Why GAO Did This Study: 

The Social Security Act requires that the Social Security 
Administration (SSA) find an improvement in a beneficiary’s medical 
condition in order to remove him or her from either the Disability 
Insurance (DI) or Supplemental Security Income (SSI) programs. GAO was 
asked to (1) examine the proportion of beneficiaries who have improved 
medically and (2) determine if factors associated with the standard 
pose challenges for SSA when determining whether beneficiaries continue 
to be eligible for benefits. To answer these questions, GAO surveyed 
all 55 Disability Determination Services (DDS) directors, interviewed 
SSA officials, and reviewed pertinent SSA data. 

What GAO Found: 

Each year, about 13,800 beneficiaries, or 1.4 percent of all the people 
who left the disability programs between fiscal years 1999 and 2005, 
did so because SSA found that they had improved medically. More 
beneficiaries leave because they convert to regular retirement 
benefits, die, or for other reasons—including having earnings above 
program limits. In addition, while continuing disability reviews (CDR) 
are SSA’s most comprehensive tool for determining whether a recipient 
continues to have a disability, on average, 2.8 percent of 
beneficiaries were found to have improved medically and to be able to 
work following a CDR during this 7-year period. 

Several factors associated with the medical improvement standard (the 
standard) pose challenges for SSA when assessing whether beneficiaries 
continue to be eligible for benefits. First, limitations in SSA 
guidance may result in inconsistent application of the standard. For 
example, SSA does not clearly define the degree of improvement needed 
to meet the standard, and the DDS directors GAO surveyed reported that 
they use different thresholds to assess if medical improvement has 
occurred. Second, contrary to existing policy, disability examiners in 
a majority of the DDSs are incorrectly conducting CDRs with the 
presumption that a beneficiary has a disability rather than with a 
“neutral” perspective. Other challenges associated with the standard 
include inadequate documentation of evidence as well as the judgmental 
nature of medical improvement determinations. All these factors have 
implications for the consistency of CDR decisions. However, due to data 
limitations, GAO was unable to determine the extent to which these 
problems affect decisions to continue or discontinue benefits.

What GAO Recommends: 

GAO is making a recommendation to SSA to clarify guidance regarding the 
degree of medical improvement required to meet the standard, the use of 
exceptions, and the presumption of disability for assessing medical 
improvement when conducting CDRs. 

While generally agreeing with the value of additional guidance, SSA 
expressed reservations about the need for further guidance on the 
exceptions. GAO continues to see such a need since 7 of the 11 
disability examiners we spoke with were uncertain regarding when to 
apply the exceptions.

The Honorable Charles E. Grassley: 
Chairman: 
Committee on Finance: 
United States Senate: 

Dear Mr. Chairman: 

In fiscal year 2005, the Social Security Administration (SSA) paid 
about $126 billion to approximately 12.8 million beneficiaries under 
the Disability Insurance (DI) and Supplemental Security Income (SSI) 
programs. These disability programs provide income support and in most 
cases, access to medical care for people unable to work due to physical 
or mental impairments, or both. In recent years, both programs have 
grown and are poised to grow even faster as the baby boom generation 
enters its disability-prone years. For example, SSA expects that by 
2010 the number of DI beneficiaries and their eligible family members 
will increase by more than one-third over 2001 levels. 

SSA is required to conduct periodic continuing disability reviews (CDR) 
to ensure that only eligible people continue to receive benefits. These 
reviews assess whether individuals are still eligible for benefits 
based on their current medical condition and ability to work, among 
other criteria.[Footnote 1] When SSA was conducting these reviews in 
the early 1980s, there were concerns that some beneficiaries were being 
arbitrarily removed from the programs. In response, Congress passed the 
Social Security Disability Benefits Reform Act of 1984[Footnote 2] (the 
act), which among other things established a medical improvement 
standard (the standard). Under this standard, unless certain exceptions 
apply, SSA must find improvement in a beneficiary's medical condition 
and that the individual is able to work in order to discontinue 
benefits.[Footnote 3] If SSA determines that the standard has been met 
in the course of conducting a CDR, the beneficiary may continue to 
receive benefits until the individual receives another CDR (which 
potentially could result in a discontinuation of benefits), dies, or 
transitions into Social Security retirement benefits. 

Since the standard has been implemented, some observers have suggested 
that certain factors associated with the standard may lead SSA to 
continue benefits for some individuals who might otherwise be able to 
work. Given this observation and the continued growth in the DI and SSI 
programs, the Senate Committee on Finance asked us to (1) examine the 
proportion of beneficiaries who are removed from the disability 
programs because they have improved medically and (2) determine if 
factors associated with the standard pose challenges when determining 
whether beneficiaries continue to be eligible for benefits. 

To address these questions, we reviewed the act, regulations, and SSA 
guidance and processes for evaluating whether beneficiaries continue to 
be eligible for benefits. We examined SSA data on CDR outcomes for a 7- 
year period (fiscal years 1999 to 2005). We looked only at DI and SSI 
adult beneficiaries.[Footnote 4] We verified the statistical data on 
CDR outcomes, interviewed knowledgeable officials about the data, and 
determined that the data were sufficiently reliable for the purposes of 
our review. Furthermore, we conducted a national survey of all 55 
Disability Determination Services (DDS) directors and received 54 
completed responses to achieve a response rate of 98 percent. In 
addition, we interviewed various SSA officials, disability experts, and 
disability advocacy groups regarding the standard. We also conducted 
site visits in three states (Massachusetts, Texas, and California). We 
selected these states based on several criteria, including number of 
disability beneficiaries, proportion of CDRs that result in a 
discontinuation of benefits, and geographic dispersion, among other 
criteria. During these visits, we conducted in-depth interviews with 80 
selected SSA officials, including DDS directors, CDR supervisors, 
disability examiners,[Footnote 5] and medical specialists. We also 
interviewed regional office disability officials, regional Office of 
Disability Adjudication and Review officials, administrative law 
judges, and regional Office of Quality Performance officials and 
examiners. Moreover, we reviewed selected CDR cases to obtain examples 
of how the standard may impact decisions to continue or discontinue 
benefits. In addition, we consulted with outside groups including the 
Social Security Advisory Board and disability advocacy groups. We 
conducted our work from October 2005 through June 2006 in accordance 
with generally accepted government auditing standards. Appendix I 
discusses our scope and methodology in more detail. The survey and a 
tabulation of the results can be viewed at [Hyperlink, 
http://www.gao.gov/cgi-bin/getrpt?rptno=GAO-07-4sp]. 

Results In Brief: 

On average, each year about 13,800 beneficiaries, or 1.4 percent of all 
the people who left the disability programs between fiscal years 1999 
and 2005, were removed because SSA found that they had improved 
medically. More beneficiaries leave the programs because they die or 
convert to regular retirement benefits. Moreover, while CDRs are the 
agency's most comprehensive tool for determining whether a recipient 
continues to have a disability, on average, about 2.8 percent of 
beneficiaries who undergo a CDR leave the DI and SSI programs due to 
medical improvement. For example, in fiscal year 2005, SSA conducted 
about 333,000 medical CDRs and discontinued disability benefits for 
about 10,300 recipients for medical improvement. 

Our review suggests that several factors associated with the standard 
pose challenges for SSA's ability to assess whether beneficiaries 
continue to be eligible for benefits. First, limitations in SSA 
guidance may result in inconsistent application of the standard. For 
example, we found that SSA does not clearly define the degree of 
improvement needed to meet the standard, and the directors we surveyed 
reported using different thresholds to show medical improvement. From 
our survey, 17 DDS directors reported that a large or very large 
increase in a recipient's ability to perform basic work activities is 
required to show medical improvement, while 24 reported that a moderate 
increase is required. In addition, while the act does provide for 
certain exceptions to medical improvement that could result in 
additional individuals having their benefits discontinued following a 
CDR, most of the disability examiners whom we spoke with on our site 
visits (7 of the 11 examiners) told us that they were uncertain about 
when to apply the exceptions. Second, incorrect application of one 
element of the standard by a majority of DDSs--CDRs should be conducted 
on a neutral basis, without a presumption that an individual continues 
to have a disability--may make it difficult to determine if 
beneficiaries have improved medically. Finally, we found that other 
factors, such as inadequate documentation of evidence and the 
judgmental nature of the decision process concerning what constitutes 
medical improvement may make it difficult for SSA to determine whether 
a beneficiary remains eligible for benefits. These problems have 
implications for the consistency and fairness of SSA's medical 
improvement decision-making process. However, due to data limitations, 
we were unable to determine the extent to which these problems actually 
affect decisions to continue or discontinue benefits. 

We are recommending that the Commissioner of Social Security clarify 
policies for assessing medical improvement. Areas that could benefit 
from improved clarity in guidance include what degree of improvement is 
needed to meet the standard, when the use of exceptions is appropriate, 
as well as clarification for DDSs about presumption of disability when 
conducting CDRs. 

SSA generally agreed with our recommendation but expressed reservations 
about the need for further guidance on the proper use of the exceptions 
to medical improvement. SSA believed that its implementation of the 
statutory exceptions is appropriate and that its instructions are 
consistent with the intent of the law. We revised the report to more 
clearly highlight that the need for further guidance stems from our 
discussions with disability examiners, most of whom expressed 
uncertainty regarding the application of the exceptions. 

Background: 

The Social Security Administration (SSA) administers two programs under 
the Social Security Act that provide benefits to people with 
disabilities: (1) Disability Insurance (DI) and (2) Supplemental 
Security Income (SSI).[Footnote 6] Established in 1956, DI is an 
insurance program that provides benefits to workers who become unable 
to work because of a long-term disability. Workers who have paid into 
the Social Security Trust Fund are insured under this program. At the 
end of calendar year 2005, the DI program served about 8.3 million 
workers with disabilities, their spouses, and dependent children and 
paid out about $85 billion in cash benefits throughout the year. Once 
found entitled, individuals continue to receive benefits until they 
either die, return to work and earn more than allowed by program rules, 
are found to have improved medically and are able to work, or reach 
regular retirement age[Footnote 7] (when disability benefits convert to 
retirement benefits). 

SSI serves people with disabilities on the basis of need, regardless of 
whether they have paid into the Social Security Trust Fund. Created in 
1972, SSI is an income assistance program that provides cash benefits 
for disabled, blind, or aged people who have low income and limited 
resources. At the end of calendar year 2005, the SSI program served 
about 6.8 million people and paid about $36 billion in federal cash 
benefits throughout the year.[Footnote 8] These cash benefits are paid 
from general tax revenues. SSI benefits generally can be discontinued 
for the same reasons as DI benefits, although SSI benefits also may be 
discontinued if a person no longer meets SSI income and resource 
requirements. Unlike the DI program, SSI benefits can continue even 
after the person reaches full retirement age. 

The Social Security Act's definition of disability for adults is the 
same under both programs. A person's physical or mental impairment must 
(1) have lasted or be expected to last at least 1 year or to result in 
death and (2) prevent or be expected to prevent him or her from being 
able to engage in substantial gainful activity (SGA) for that period of 
time. People are generally considered to be engaged in SGA if they earn 
above a certain dollar level. For 2006, SSA considers countable 
earnings above $860 a month to be SGA for an individual who is not 
blind and $1,450 a month for an individual who is blind. 

History of the Medical Improvement Standard and the Current Continuing 
Disability Review Process: 

Prior to 1980, some studies indicated that many beneficiaries of the 
disability programs no longer had a disability and could work. To 
ensure that only eligible beneficiaries remained in the programs, 
Congress passed a law requiring SSA to conduct continuing disability 
reviews (CDR) beginning in January 1982. State Disability Determination 
Services (DDS) examiners began conducting medical CDRs under the same 
criteria used to evaluate initial disability claims. In 1981 and 1982, 
about 45 percent of those individuals who received a CDR had their 
benefits discontinued.[Footnote 9] There was no statutory requirement 
for SSA to show that a beneficiary had improved medically in order to 
remove him or her from the programs. Disability advocacy groups and 
others became concerned that some beneficiaries were being 
inappropriately removed from the disability programs, and by 1984 SSA 
placed a moratorium on all CDRs. 

To address concerns that some beneficiaries were being inappropriately 
removed from the programs, Congress enacted the Social Security 
Disability Benefits Reform Act of 1984. The act included a provision 
requiring SSA to find substantial evidence demonstrating medical 
improvement before ceasing a recipient's benefits (the medical 
improvement standard). SSA resumed CDRs in January 1986 using this 
standard, which is among the first steps of the CDR evaluation 
process.[Footnote 10] The standard has the following two elements that 
need to be met: 

* Is there improvement in a beneficiary's medical condition? The 
regulations implementing the act define improvement as any decrease in 
the medical severity of the beneficiary's impairment(s) since the last 
time SSA reviewed his or her disability, based on changes in symptoms, 
signs, or laboratory findings. 

* Is this improvement related to the ability to work? Improvement 
related to the ability to work is evaluated two different ways, 
depending on whether the comparison point decision (CPD) was based on: 
(1) meeting or equaling a prior disability listing[Footnote 11] or (2) 
a residual functional capacity (RFC) assessment.[Footnote 12] 

* Meeting or equaling the prior listing: In this case, a disability 
examiner will determine if the beneficiary's same impairment(s) still 
meets or equals the prior listing. A disability examiner compares the 
beneficiary's condition with the list of impairments in effect at the 
time he or she was first awarded disability benefits.[Footnote 13] If 
the impairment(s) meets or equals the prior listing, then benefits are 
continued. If not, then the examiner proceeds with the CDR evaluation. 

* Residual functional capacity assessment: In this case, a disability 
examiner compares the beneficiary's previous functional capacity to the 
current functional capacity for the same impairment. If functional 
capacity for basic work activities has improved, then the examiner 
finds that the medical improvement is related to the ability to work 
and proceeds with the CDR evaluation. 

The act allows SSA to discontinue benefits even when the beneficiary 
has not improved medically if one of the specific "exceptions" to 
medical improvement applies[Footnote 14] 

* the person benefits from advances in medical or vocational therapy or 
technology, 

* the person has undergone a vocational therapy program that could help 
him or her work, 

* new or improved diagnostic techniques or evaluations reveal that the 
impairment is less disabling than originally thought, or: 

* the prior decision was in error. 

In order to be removed from the disability programs for one of the 
exceptions, disability examiners must also show that the individual has 
the ability to engage in SGA. 

SSA does not conduct CDRs on all beneficiaries each year. At the time 
beneficiaries enter the DI or SSI programs, DDSs determine when they 
will be due for CDRs based on their likely potential for medical 
improvement. Based on SSA regulations, DDSs classify beneficiaries into 
one of three medical improvement categories: 

* medical improvement expected--CDR generally once every 6 to 18 
months; 

* medical improvement possible--CDR once every 3 years; or: 

* medical improvement not expected--CDR once every 5 to 7 years. 

SSA has also developed a method, called profiling, to determine the 
most cost-effective method of conducting a CDR. SSA applies statistical 
formulas that use data on beneficiary characteristics--such as age, 
impairment type, length of time on disability programs, previous CDR 
activity, and reported earnings--to predict the likelihood of medical 
improvement and, therefore, of benefit discontinuation. SSA assigns a 
"score" to beneficiaries indicating whether there is a high, medium, or 
low likelihood of medical improvement. In general, beneficiaries with a 
high score are referred for full medical CDRs. Beneficiaries with lower 
scores are, at least initially, sent a questionnaire, known as a 
"mailer."[Footnote 15] Full medical CDRs involve an in-depth 
examination of a beneficiary's medical and possibly his or her 
vocational status. This may include a review of the recipient's case 
file, physical and psychological condition, and medical evidence by a 
disability examiner and physician. Unlike full medical CDRs, CDR 
mailers consist of a short list of questions asking beneficiaries to 
self-report information on their medical condition, treatments, and 
work activities. Appendix II describes the medical CDR evaluation 
process in detail. 

SSA will find that disability has ended and discontinue 
benefits[Footnote 16] if it determines that medical improvement related 
to the ability to work has occurred or that one of the exceptions 
applies, and the person's impairments are not severe or the person can 
do past work or other work. If SSA determines that medical improvement 
has not occurred and that none of the exceptions apply, then benefits 
are continued[Footnote 17] (see fig. 1).

differ for beneficiaries covered by certain work incentive programs. 

[B] If a group II exception applies, discontinue benefits immediately 
without a medical determination. 

[C] Consider age and time on the disability programs. 

[End of figure] 

If SSA finds that the individual no longer has a disability and 
discontinues benefits following a CDR, the individual has the right to 
appeal the CDR decision, first to another reviewer for a 
reconsideration, second to an administrative law judge, then to the 
Appeals Council, and finally to federal courts. At the hearing before 
the administrative law judge (ALJ), the ALJ reviews the file, including 
any additional evidence submitted after the DDS determination and may 
hear testimony from the individual as well as medical and vocational 
experts. 

SSA's Office of Quality Performance conducts quality reviews of 
disability determination outcomes. To conduct these quality reviews, 
SSA selects a random sample of cases each month from all final CDR 
decisions, stratifying the selection of cases by state and outcome 
(cases where benefits are continued and discontinued). Then, a quality 
examiner reviews the case to ensure it adheres to SSA guidance, 
including a review of the DDS decision, the documentation of that 
decision, and the evidence contained in the case. During these reviews, 
physicians[Footnote 18] evaluate the evidence to ensure that the 
decision adheres to the medical improvement standard. In fiscal year 
2005, SSA's Office of Quality Performance reported nationwide accuracy 
rates for cases where CDR benefits were continued and discontinued of 
95 percent and 93 percent respectively. The combined accuracy rate for 
all CDRs was about 95 percent. 

Few Beneficiaries Are Removed from the Disability Programs Because They 
Are Found to Have Improved Medically: 

We found that on average, about 1.4 percent of all individuals who left 
the programs between fiscal years 1999 and 2005 were removed for 
medical improvement. More beneficiaries leave the disability programs 
because they either die or convert to social security retirement 
benefits. In addition, while full medical CDRs are the agency's most 
comprehensive tool for determining whether a beneficiary continues to 
have a disability, about 2.8 percent of those who receive these CDRs 
are found to no longer have a disability under the medical improvement 
standard. 

Few Beneficiaries Are Removed from the Programs Due to Medical 
Improvement: 

Between fiscal years 1999 and 2005, annually, an average of 
13,800[Footnote 19] people--or about 1.4 percent of all individuals who 
left the disability programs--were removed because SSA found that they 
had improved medically.[Footnote 20] More people leave the programs 
when they die, convert to full retirement benefits,[Footnote 21] or 
leave for other reasons. For example, between fiscal years 1999 and 
2005, each year an average of about 311,000[Footnote 22] recipients 
(about 32 percent of all recipients who were removed from the 
disability programs) died, and about 209,000 (about 21 percent) 
converted from DI benefits to retirement benefits. In addition, each 
year about 444,000 beneficiaries (about 45 percent) were removed from 
the disability programs for other reasons. These include about 54,000 
DI beneficiaries who SSA determined had earnings in excess of SGA, 
about 11,000 DI beneficiaries who either converted to old-age 
retirement benefits prior to reaching the full retirement age[Footnote 
23] or were found to be erroneously eligible for benefits, and about 
379,000 SSI beneficiaries who were removed from the SSI program for all 
reasons other than death and medical improvement (including earnings 
and resources above the limit allowed by program guidelines) (see fig. 
2). 

Figure 2: Average Percentage of All Beneficiaries Who Were Removed from 
the DI and SSI Programs by Category (Fiscal Years 1999 to 2005): 

[See PDF for image] 

Source: GAO analysis of SSA data. 

Note: While the combined DI and SSI programs in figure 2 illustrate the 
reasons why beneficiaries are removed from the DI and SSI programs, 
there are some differences between these two programs. For the same 
time period, for the DI program, about 2 percent of all recipients who 
were removed from the DI program improved medically; about 45 percent 
converted from disability benefits to retirement benefits; about 39 
percent died; about 12 percent had earnings in excess of SGA; and about 
2 percent left for other reasons. For the SSI program, about 1 percent 
of all recipients who were removed from the SSI program improved 
medically; about 25 percent died; and about 74 percent left for other 
reasons. 

[End of figure] 

During fiscal years 1999 to 2005, the proportion of all beneficiaries 
who were removed from the programs in each of the above categories 
remained fairly consistent. For example, during this period, the 
proportion of individuals removed from the disability programs in a 
fiscal year for medical improvement ranged from 1.0 percent to 1.7 
percent; the proportion of individuals who died ranged from 31.1 
percent to 33.0 percent; and the proportion of individuals who 
converted from disability benefits to retirement benefits ranged from 
19.7 percent to 22.7 percent. 

Few Beneficiaries Who Receive Full Medical Continuing Disability 
Reviews Are Removed from the Programs Each Year: 

SSA data show that few beneficiaries who receive medical CDRs are 
removed from the disability programs. Full medical CDRs are the 
agency's primary tool to determine whether a beneficiary has improved 
medically. Between fiscal years 1999 and 2005, the number of full 
medical CDRs conducted ranged from a high of 608,000 in 2001 to a low 
of 333,000 in 2005 (see fig. 3).[Footnote 24] Between fiscal years 1999 
and 2005, an average of about 26,000 individuals each year (about 5.3 
percent) were removed from the disability programs as a result of 
receiving a medical CDR. Some of the officials we interviewed stated 
that the medical improvement standard may artificially limit the 
percentage of recipients who are found to have improved medically. 
However, we were unable to identify any empirical data regarding the 
impact of the standard on the percentage of recipients who have their 
benefits discontinued, or what a "proper" discontinuation rate should 
be. 

While the number of CDRs conducted between fiscal years 1999 and 2005 
fluctuated,[Footnote 25] the percentage of beneficiaries removed from 
the programs remained fairly constant.[Footnote 26] For example, in 
fiscal years 1999, 2002, and 2004, the percentage of recipients who 
were removed from the disability programs as a result of receiving a 
CDR was 5.4 percent, 5.6 percent, and 5 percent respectively. In 
addition to medical improvement, SSA also removes beneficiaries for 
failing to cooperate during a CDR. For example, a beneficiary may fail 
to appear for scheduled meetings with disability examiners or 
physicians and thus may have their benefits discontinued. Of the 
individuals removed from the programs as a result of receiving a CDR 
between fiscal years 1999 and 2005, an average of about 13,800 
individuals (or 2.8 percent of all CDRs conducted between fiscal years 
1999 and 2005) were removed annually because SSA determined that they 
had improved medically, while an average of about 10,300 individuals 
(or about 2.1 percent) were removed each year for failure to cooperate.

Several Factors Challenge SSA's Ability to Assess Whether Beneficiaries 
Continue to Be Eligible for Benefits: 

Our review suggests that several factors associated with the standard 
pose challenges for SSA's ability to assess whether beneficiaries 
continue to be eligible for benefits. First, limitations in SSA 
guidance may result in inconsistent application of the standard. For 
example, we found that SSA does not clearly define the degree of 
improvement needed to meet the standard, and the DDS directors we 
surveyed reported using different thresholds to show medical 
improvement. As a result of this apparent limitation in SSA guidance, 
disability examiners may incorrectly decide to continue or discontinue 
benefits. In addition, while the act provides for certain exceptions 
that could result in additional individuals having their benefits 
discontinued following a CDR, most of the disability examiners we spoke 
with told us that they were uncertain about when to apply the 
exceptions. Second, we found that most DDSs are incorrectly conducting 
CDRs with the presumption that a beneficiary has a disability. Finally, 
other factors, such as inadequate documentation of evidence and the 
judgmental nature of the decision process for assessing medical 
improvement may make it more difficult to determine whether a 
beneficiary remains eligible for benefits. However, due to data 
limitations, we were unable to determine the extent to which these 
challenges impact decisions to continue or discontinue benefits during 
a CDR. 

Limitations in SSA Guidance for Applying the Medical Improvement 
Standard May Result in Inconsistent Disability Decisions: 

Our work shows that SSA does not clearly define the degree of 
improvement needed for examiners to determine if a beneficiary has 
improved medically. Many disability examiners and DDS officials told us 
that they were unsure about the degree of improvement required to meet 
the standard, and some said this confusion stems from unclear SSA 
guidance. In particular, SSA guidance instructs examiners to disregard 
"minor" changes in a beneficiary's condition.[Footnote 27] However, 
this guidance does not adequately describe what constitutes a minor 
change. When we asked SSA officials to clarify their understanding of 
what constitutes a minor change, they told us that only changes that 
would not affect a beneficiary's ability to work should be considered 
minor. However, this explanation of minor changes is not included in 
the agency's guidance. As a result, some DDSs may be inconsistently 
defining what constitutes a minor change. For example, five DDS 
directors told us that they define minor changes to include those that 
may actually improve functioning or allow the beneficiary to work. In 
doing so, our review suggests that some DDSs may be inconsistently 
applying the standard as to what constitutes medical improvement. 
However, DDS directors differed on the extent to which the guidance to 
disregard minor changes impacts CDRs. Of the 52 DDS directors who 
answered a question in our survey on "minor" changes, 21 reported that 
the practice of disregarding minor changes is not an impediment to 
making a disability determination, while 31 reported that it is an 
impediment.[Footnote 28] 

Similarly, we found that SSA guidance may not provide DDS examiners 
with sufficient detail to determine whether improvements in 
beneficiaries' medical conditions are related to their ability to work. 
At this step of the CDR process, examiners look for changes in a 
beneficiary's ability to perform basic work activities since the last 
review, such as lifting heavy objects or standing or sitting for 
periods of time.[Footnote 29] The guidance instructs examiners to 
ensure a "reasonable relationship" between the amount of improvement 
and the increase in the ability to perform basic work 
activities.[Footnote 30] However, the guidance does not require a 
specific amount of increase in functioning. The DDS directors we 
surveyed reported that they interpret this guidance differently. 
Specifically, 17 of 49 directors reported that a large or very large 
increase in a recipient's ability to do basic work activities is 
required; 24 reported that a moderate increase is required; and 8 
reported that a minor or any increase at all is required. Furthermore, 
two DDS directors in our survey inaccurately noted that the standard 
requires that a beneficiary's improvement be great enough so that it 
actually enables the individual to work.[Footnote 31] One of these 
directors commented that because SSA guidance on this aspect of the 
standard is open to broad interpretation, it is difficult to document 
improvement to the extent the individual is able to work. As a result, 
some DDSs may be inconsistently applying this aspect of the standard 
that could potentially impact decisions to continue or discontinue 
benefits. However, we were unable to determine how much of an impact 
clarification of this guidance would have on CDR outcomes. 

The disability advocates we spoke with differed in their views on the 
clarity of SSA guidance on medical improvement. While some stated that 
it is clear and adequate, others stated that the guidance on assessing 
medical improvement in psychological impairments and determining if 
improvement is related to the ability to work is confusing and unclear. 
One advocate stated that current SSA policies contribute to some 
recipients remaining in the disability programs despite their ability 
to work. 

We also found that while the act provides for exceptions to medical 
improvement that could result in additional individuals having their 
benefits discontinued as a result of receiving a CDR, most of the 
disability examiners whom we spoke with on our site visits told us that 
they were uncertain about when to apply the exceptions.[Footnote 32] 
SSA policies allow for various exceptions, including when the prior 
decision was in error or when persons benefit from education or 
training programs that could help the individuals work. However, we 
found that while the examiners and ALJs routinely assess whether a 
beneficiary has improved medically, they do not routinely assess 
whether or not each of the exceptions applies to the case. Moreover, 
many of the DDS officials and examiners we interviewed told us that the 
guidelines for using the error exception are written in a way that 
precludes its use, except in the most extreme situations.[Footnote 33] 

SSA officials explained that the exceptions were written to 
intentionally limit their use in order to prevent examiners from 
circumventing the standard, and that their infrequent use is 
appropriate. In addition, SSA explained that when it issued the final 
rules governing the medical improvement standard, it intended the 
exceptions to be true "exceptions"--not to be routinely applied 
(including the error exception). The agency also noted that a broader 
application of the error exception could lead to a substitution of 
judgment by an adjudicator for the original finding of disability in 
instances where a person's medical condition had not substantially 
improved. Some disability advocates we spoke with also noted that the 
narrow interpretation of the error exception is appropriate because it 
prevents substitution of judgment and arbitrary discontinuations. 

A Majority of DDSs Incorrectly Apply SSA Guidelines Stating That CDRs 
Should Be Conducted Neutrally, without a Presumption of Disability: 

According to our survey, a majority of DDSs incorrectly presume that a 
beneficiary continues to have a disability when conducting CDRs, which 
may make it more difficult for examiners to determine if a beneficiary 
has improved medically. This is contrary to the act as well as SSA 
regulations and policy, which require that CDR decisions be made on a 
"neutral basis." SSA defines neutral basis as a review that neither 
presumes that a beneficiary (1) is still disabled because he or she was 
previously found disabled and (2) is no longer disabled because he or 
she was selected for a CDR. Under a neutral review, it is assumed that 
beneficiaries had a disability at the time of the prior decision, but 
it is not assumed they still have a disability at the time of a CDR. 
However, in survey responses, 31 DDS directors responded that in 
practice, CDRs are conducted with the presumption that a beneficiary 
continues to have a disability.[Footnote 34] When asked to explain this 
response, directors cited various factors that likely contribute to the 
presumption of disability during a CDR. Thirteen directors commented 
that the individuals are already receiving disability benefits, and as 
a result, the directors assume that the beneficiary continues to have a 
disability. Some of these directors also noted that they make this 
presumption because the beneficiary was found disabled when initially 
awarded benefits, and examiners must show medical improvement to remove 
them from the programs. 

Since a majority of DDSs are conducting CDRs with a presumption that 
beneficiaries have a disability, those DDSs may be setting a higher bar 
than required by the standard for these reviews. Moreover, by requiring 
more evidence of medical improvement than is necessary under the 
standard, it may be harder to assess whether a recipient no longer has 
a disability and is able to work. Because 31 directors reported that 
examiners conduct CDRs with the presumption that beneficiaries continue 
to have a disability, a significant number of beneficiaries may be 
evaluated under this higher standard, and some may have their benefits 
erroneously continued. While these problems raise concerns about the 
consistency of decisions when determining if medical improvement has 
occurred, the ultimate impact of presuming that an individual has a 
disability on CDR decisions is unknown because we were unable to 
empirically test how the presumption of a disability impacts CDR 
decisions to continue or discontinue benefits. 

Other Factors May Make Assessing Medical Improvement Difficult: 

Inadequate documentation of evidence and the judgmental nature of the 
process for assessing medical improvement are two additional factors 
that make it challenging to assess medical improvement. The standard 
establishes the prior decision as the starting point for conducting a 
CDR and requires examiners to find evidence of medical improvement 
since this last decision. Some DDS directors reported that it may be 
difficult to assess medical improvement in cases where the prior 
disability decision was based on incomplete or poorly documented 
evidence. For example, in one of the CDR cases we reviewed, a 
beneficiary had his benefits continued following the CDR because the 
rationale for the prior disability decision was vague, according to the 
examiner who reviewed the case with us. This beneficiary was originally 
awarded benefits on appeal based on recurrent stomach problems and 
depression. When the case was selected for a CDR, the case file 
included a general description of the beneficiary's medical condition, 
but lacked sufficient evidence to determine if medical improvement had 
occurred since the initial decision, according to the examiner. As a 
result, medical improvement could not be shown and benefits were 
continued. While many examiners and officials we interviewed agreed 
that it is difficult to show medical improvement in cases that lack 
adequate documentation, they differed in their opinions about how 
frequently this occurs. Of the directors who answered our survey 
question on insufficient documentation, 33 responded that they 
encounter cases with insufficient documentation infrequently or very 
infrequently, and 17 responded that such cases occurred more 
often.[Footnote 35] 

Survey respondents also differed in their opinions about the types of 
cases that more typically lack adequate documentation, but 15 directors 
commented that cases decided on appeal were the most likely to lack 
adequate documentation. One possible explanation for this may be 
streamlined processes at the appeals level. For example, one ALJ we 
interviewed noted that, in an effort to process cases in a timely 
manner, ALJs sometimes issue quick decisions in which most of the 
evidence is on tapes that are not transcribed or placed in the 
beneficiary's case file. In such instances, it is unlikely that the DDS 
examiner would have complete information for conducting a CDR and 
determining if medical improvement had taken place. Furthermore, 
several officials told us that guidance instructs ALJs to include 
enough information in their decisions so that the decisions will be 
legally sufficient. However, the guidance does not specifically 
instruct ALJs to include all of the evidence that will be needed to 
assess medical improvement at a future CDR. However, in recent 
regulations to implement changes to its disability determination 
process, SSA is taking steps that may help to address the problem of 
incomplete documentation for future CDRs. Specifically, SSA is 
developing requirements for training examiners to ensure they 
understand the information needed to make accurate and adequately 
documented decisions, has adopted guides for decision writing at the 
appeals level, and is in the process of developing guides for use at 
the DDS level. 

In addition to the challenges associated with problems of inadequate 
documentation, many examiners also told us that the judgmental nature 
of the decision process concerning what constitutes an improvement can 
make it difficult to assess medical improvement. One examiner may 
determine that a beneficiary has improved medically and discontinue 
benefits, while another examiner may determine that medical improvement 
has not been shown and will continue the individual's benefits. For 
example, in one of the CDR cases that we reviewed, the examiner 
conducting the initial CDR determined that medical improvement was 
shown and discontinued the individual's benefits. The recipient was 
initially awarded disability benefits for a back injury with limited 
range of motion in the recipient's back. When the CDR was conducted, 
the examiner evaluated all of the relevant evidence and concluded that 
the individual's range of motion had improved. The examiner also noted 
that the individual's allegations of pain did not correlate with the 
findings from both the physical exam and the laboratory findings. As a 
result, the examiner concluded that medical improvement had occurred. 
On appeal to reconsideration 6 months later, a different DDS examiner 
conducted a review using the same medical evidence as the original 
examiner, but determined that medical improvement had not occurred, and 
continued benefits. The examiner conducting the appeal concluded that 
the beneficiary continued to experience pain consistent with the back 
condition, and thus medical improvement was not shown. However, we had 
no basis for determining which decision was correct. 

The amount of judgment involved in the decision-making process 
increases when the process involves certain types of impairments that 
are difficult to assess. More specifically, assessing medical 
improvement may be more difficult in cases that involve certain types 
of psychological impairments, such as depression, than cases with 
physical impairments, such as amputations. In elaborating on their 
survey responses, 17 directors commented that assessing medical 
improvement is more difficult in cases with psychological impairments 
because evidence of these impairments is generally more subjective than 
evidence of many physical impairments. In addition, six directors 
commented that evaluations of psychological impairments tend to rely 
more heavily on assessment of functionality. According to some of these 
officials, an assessment of functionality is more subjective because it 
relies more on the beneficiaries' account of their own conditions than 
on laboratory findings. Furthermore, some officials reported that the 
severity of psychological impairments can fluctuate over time, making 
it difficult to assess whether improvement has taken place. Two 
directors commented that determining whether there is medical 
improvement for some types of psychological impairments can also be 
complicated because medical experts' opinions can vary. One of these 
directors commented that the evidence to support psychological 
impairments, such as evaluations for depression, rely less on 
laboratory findings and more on clinical judgment. In contrast, certain 
tests for physical impairments tend to be less open to interpretation. 
For example, one director commented that X-rays of joint deterioration 
can generally be interpreted consistently among radiologists. The 
potential difficulty of assessing medical improvement in beneficiaries 
whose disability is based on certain types of psychological impairments 
is especially relevant, given that the proportion of all individuals in 
the disability programs whose disability is based on a psychological 
impairment has grown in recent years. 

Conclusions: 

SSA is responsible for assuring that individuals who truly have a 
disability that prevents them from being able to work continue to 
receive benefits. At the same time, SSA has a stewardship 
responsibility to identify those beneficiaries who have improved 
medically and are no longer eligible for benefits. The medical 
improvement standard is intended to help SSA accomplish both of these 
responsibilities. However, several factors associated with the standard 
pose challenges for ensuring that the standard is implemented in a 
consistent and fair manner. Specifically, potential limitations in SSA 
guidance regarding the degree of improvement needed to meet the 
standard as well as a lack of clarity with respect to the appropriate 
use of the exceptions to medical improvement may make it difficult to 
assess if medical improvement has occurred. Clear guidance is 
especially important in view of the judgmental nature of the disability 
determination process. Additionally, while SSA guidelines regarding the 
presumption of disability during CDRs tend to be generally clear, 
incorrect application of these guidelines by several DDSs suggests that 
the outcomes of CDRs could be affected and may result in benefit 
continuation for some individuals who might otherwise been found to 
have improved medically. Other factors, including inadequate 
documentation of evidence, are more difficult to address in the short 
term. However, SSA is taking actions intended to address some of these 
problems. 

Recommendation: 

To ensure that SSA is able to consistently assess whether DI and SSI 
beneficiaries have improved medically, we recommend that the 
Commissioner of Social Security clarify guidance for assessing medical 
improvement when conducting CDRs. More specifically, SSA should clarify 
guidance concerning (1) what degree of improvement is required to meet 
the standard and (2) when the use of exceptions to medical improvement 
is appropriate. SSA should also work with DDSs to ensure that CDRs are 
conducted on a neutral basis, without a presumption that beneficiaries 
continue to have a disability. 

Agency Comments and Our Evaluation: 

We obtained written comments on a draft of this report from the 
Commissioner of the Social Security Administration (SSA). The agency 
generally agreed with our recommendation, but expressed reservations 
about the need for further guidance on the use of exceptions. More 
specifically, SSA believed that its implementation of the statutory 
exceptions to medical improvement is appropriate and that its 
instructions are consistent with the intent of the law. As such, SSA 
was concerned about language in the draft report that characterized 
SSA's guidance as discouraging and limiting the use of the exceptions. 
After considering these comments, we revised the report to include 
additional information on (1) examiners' confusion on the use of the 
exceptions when conducting CDRs and (2) SSA's rationale for its current 
exception guidance. Having made these changes, we continue to believe 
that additional guidance in this area is warranted if only, as the 
report notes, because most of the disability examiners whom we spoke 
with told us that they were uncertain about when to apply the 
exceptions. Moreover, while answering a survey question on the 
exceptions to medical improvement, 4 DDS directors commented that more 
guidance regarding the use of the exceptions is needed. 

SSA generally agreed with the need for clarifying guidance concerning 
the degree of improvement required to meet the medical improvement 
standard. However, the agency believed that the report was unclear with 
regard to whether this part of the recommendation applied only to 
guidance for determining if there has been any medical improvement, or 
also to the guidance for determining if any medical improvement is 
related to the ability to work. As stated in the draft report, our 
discussion of medical improvement encompasses both elements 
(improvement in a beneficiary's medical condition and its relation to 
the ability to work). However, we did further clarify this throughout 
the entire report to minimize any confusion on this matter. 
Additionally, SSA indicated that clarification of this guidance would 
probably have little noticeable impact on the number of cases in which 
SSA finds that a disability has ended. As our report notes, we cannot 
quantify the impact that clearer guidance would have on the 
discontinuation of benefits. Even so, we continue to believe that it is 
important for DDSs to consistently apply this aspect of the medical 
improvement standard and that, towards that end, additional guidance 
would be useful. 

SSA agreed with the need for further training to ensure that CDRs be 
conducted on a neutral basis. However, it believed that more 
adjudicator training in this area would likely have little impact on 
discontinuing benefits. We cannot predict the impact additional 
guidance and training would have on continuing or discontinuing 
benefits. However, as the report points out, there are large numbers of 
DDS directors who are incorrectly applying the neutrality standard and, 
in our view, would benefit from additional guidance in this area. 

Beyond commenting on our recommendation, SSA suggested that we provide 
additional context for some of the statistical information presented in 
our discussion of the proportion of beneficiaries removed from the 
disability programs each year. For example, SSA commented that the 
disability discontinuation rates in the early 1980s may not have been 
representative of the discontinuation rates prior to the implementation 
of the medical improvement standard due to special targeted initiatives 
aimed at removing individuals from the DI program who no longer had a 
disability. We revised the report to take into account these 
suggestions. 

The Commissioner's comments have been reproduced in appendix III. SSA 
also provided additional technical comments, which have been 
incorporated in the report as appropriate.

Appendix I: Scope and Methodology: 

This appendix provides additional details about our analysis of the 
medical improvement standard (the standard), including challenges the 
standard poses for the Social Security Administration (SSA) when 
conducting medical continuing disability reviews (CDR). To meet the 
objectives of this review, we reviewed prior studies by GAO, SSA, SSA's 
Inspector General, Congressional Research Service, and external 
organizations related to the disability determination process and CDRs. 
We also reviewed the Social Security Disability Benefits Reform Act of 
1984, regulations, and SSA policies and processes for assessing whether 
beneficiaries continue to be eligible for benefits. In addition, we 
analyzed SSA data on CDR outcomes over a 7-year period for fiscal years 
1999 to 2005 as well as reports identifying the number of beneficiaries 
who leave the disability programs and the reasons why they leave. For 
the purposes of our study, we only assessed DI and SSI adult 
beneficiaries who left the programs as a result of receiving a full 
medical CDR. We did not include children or "age 18 re-determinations" 
in our analysis since there are differences between the medical CDR 
sequential evaluation processes for adults and children. We also did 
not assess the outcome of CDR mailers or work CDRs. We verified the 
statistical data on CDR outcomes for internal logic, consistency, and 
reasonableness. We determined that the data were sufficiently reliable 
for the purposes of our review. We also met with knowledgeable SSA 
officials to further document the reliability of these data. 

We interviewed 34 officials from SSA's central offices (including 
officials from the Office of the Chief Actuary, the Office of Quality 
Performance, the Office of General Counsel, the Office of Research and 
Evaluation Statistics, the Office of Disability Programs, the Office of 
Disability Adjudication and Review, and the Office of Program 
Development and Research) to discuss the disability programs and the 
CDR process. 

We conducted a national Web-based survey of all 55 Disability 
Determination Services (DDS) directors in the 50 states, the District 
of Columbia, Puerto Rico, the Virgin Islands, the Western Pacific 
Islands, and the federal DDS. DDSs are the agencies responsible for 
conducting periodic CDRs to determine if beneficiaries' medical 
conditions have improved and if they are able to work. We received 54 
completed surveys for a response rate of 98 percent. The purpose of 
this survey was to assess the extent to which the standard impacts 
outcomes of CDRs and determine if the standard poses any special 
challenges for SSA when determining whether beneficiaries continue to 
be eligible for benefits. We asked the directors about particular 
elements of the standard and how these elements, alone or in 
combination with other factors, impact CDR outcomes. We also asked them 
how SSA guidance on implementing the standard affects CDR outcomes. We 
determined that the survey data are sufficiently reliable. Because this 
was not a sample survey, there are no sampling errors. However, the 
practical difficulties of conducting any survey may introduce errors, 
commonly referred to as nonsampling errors. For example, difficulties 
in how a particular question is interpreted, in the sources of 
information that are available to respondents, or in how the data are 
entered into a database or were analyzed, can introduce unwanted 
variability into the survey results. We took steps in the development 
of the questionnaire, the data collection, and the data analysis to 
minimize these nonsampling errors. For example, social science survey 
specialists designed the questionnaire in collaboration with GAO staff 
with subject matter expertise. Then, the draft questionnaire was 
pretested with a number of state officials to ensure that the questions 
were relevant, clearly stated, and easy to comprehend. The 
questionnaire was also reviewed by an additional GAO survey specialist. 
When the data were analyzed, a second, independent analyst checked all 
computer programs. Since this was a Web-based survey, respondents 
entered their answers directly into the electronic questionnaire. This 
eliminated the need to have the data keyed into a database thus 
removing an additional source of error. We conducted three pretests of 
this survey with DDS directors in three different states. We modified 
the survey to take their comments into account. We also provided SSA 
with a copy of the survey and incorporated its technical comments into 
the final version. This report does not contain all the results from 
the survey. The survey and a more complete tabulation of the results 
can be viewed at [Hyperlink, http://www.gao.gov/cgi-
bin/getrpt?rptno=GAO-07-4sp]. 

To augment information from our state survey, we conducted independent 
audit work in three states (California, Massachusetts, and Texas) to 
examine how SSA policies and procedures are carried out in the field. 
We selected locations for field visits based on the following criteria: 
(1) geographic dispersion; (2) states with large numbers of CDRs 
conducted; (3) states with CDR discontinuation rates above, below, and 
at the national average; (4) states with varying DDS structures (i.e., 
centralized and decentralized); and (5) states with large numbers of 
Disability Insurance (DI) beneficiaries and large DI expenditures. In 
each state, we visited a DDS office, the SSA regional office, the 
regional Office of Quality Performance, and the regional Office of 
Disability Adjudication and Review (formerly known as the Office of 
Hearings and Appeals). In total, we conducted in-depth interviews with 
80 SSA and DDS managers and line staff responsible for conducting 
medical CDRs, including DDS directors, CDR supervisors and examiners, 
medical consultants, and administrative law judges.[Footnote 36] 

During our meetings with SSA and DDS officials, we documented 
management and staff views on the challenges associated with applying 
the medical improvement standard. In particular, we documented 
management and staff views on (1) the impact of the standard on CDR 
outcomes, (2) the effectiveness of SSA policies and procedures for 
applying the standard, and (3) the degree to which factors external to 
the standard create challenges when determining if a beneficiary has 
improved medically and is able to work. To further assess how the 
standard is applied in practice, we took a nonprobability sample of 12 
CDR case files from the DDSs in California and Texas. We asked CDR 
supervisors to provide several cases that were (1) discontinued for 
medical improvement, (2) continued because the beneficiary was clearly 
disabled, and (3) ambiguous cases where it was difficult to apply the 
standard and determine if benefits should be continued or discontinued. 
These case files serve to illustrate the difficulties examiners face 
when determining if a beneficiary has improved medically and is able to 
work. 

In addition, we interviewed seven disability policy experts from 
national disability research and advocacy organizations to obtain their 
input on the impact of the standard on the disability programs and any 
challenges it poses when assessing individuals' continued eligibility 
for benefits. We spoke with individuals affiliated with the following 
organizations: 

* American Association of People with Disabilities, 

* Center for Health Services Research and Policy at George Washington 
University, 

* Center for the Study and Advancement of Disability Policy, 

* Consortium for Citizens with Disabilities, 

* Disability Law Center, 

* Disability Policy Collaboration, 

* National Organization of Social Security Claimants' Representatives, 
and: 

* National Organization on Disability. 

Finally, we spoke with representatives from the National Association of 
Disability Examiners, the National Council of Disability Determination 
Directors, and the Social Security Advisory Board. We spoke with these 
disability experts about the effect of the standard on CDR outcomes and 
any challenges it presents when conducting CDRs. We conducted our work 
from October 2005 through June 2006 in accordance with generally 
accepted government auditing standards. 

[End of section] 

Appendix II: The Continuing Disability Review Evaluation Process: 

In the first step of the CDR evaluation process for adult 
beneficiaries, an SSA field office representative determines if the 
beneficiary is working at the level of substantial gainful activity 
(SGA). A beneficiary who is found to be not working or working but 
earning less than the SGA level (minus allowable exclusions) has his or 
her case forwarded to the state Disability Determination Services 
(DDS).[Footnote 37] 

The second step is to determine if the individual's current 
impairment(s) is included on the current list of disabilities that SSA 
maintains. The list describes impairments that, by definition, are so 
severe that they are disabling. If the individual's current 
impairment(s) does meet or equal a current listing, then the DDS 
continues the individual's benefits and does not continue with the 
evaluation process. If the individual's current impairment(s) does not 
meet or equal a current listing, then the DDS proceeds to step three in 
the evaluation process. 

The third step is to determine if improvement in the individual's 
medical condition has occurred. This improvement is any decrease in the 
medical severity of the impairment(s) that was present at the time of 
the most recent favorable medical decision (i.e., the initial decision 
to award disability benefits or the most recent CDR continuance-- 
usually referred to as the comparison point decision, or CPD). At this 
step, the DDS examiner compares the current signs, symptoms, and 
laboratory findings associated with the beneficiary's impairment(s) to 
those recorded from the last review. If improvement has not occurred, 
the disability examiner skips to the fifth step in the evaluation. If 
improvement has occurred, the disability examiner proceeds to next 
step, the fourth step. 

The fourth step is to determine if the improvement found in step three 
is related to the ability to work. Improvement related to the ability 
to work is evaluated two different ways, depending on whether the CPD 
was based on: (1) meeting or equaling a prior listing or (2) a residual 
functional capacity (RFC) assessment: 

* Meeting or equaling the prior listing: In this case, the disability 
examiner will determine if the beneficiary's same impairment(s) still 
meets or equals the prior listing. Unlike step two, the examiner 
compares the beneficiary's condition with the list of impairments in 
effect at the time he or she was first awarded disability 
benefits.[Footnote 38] If the impairment(s) no longer meets or equals 
the prior listing, then the examiner finds that the improvement is 
related to the ability to work and proceeds to step six of the 
evaluation process. If the impairment(s) meets or equals a prior 
listing, then benefits are continued. 

* Residual functional capacity assessment: In this case, the disability 
examiner compares the beneficiary's previous functional capacity to the 
current functional capacity for the same impairment. If functional 
capacity for basic work activities has improved, then the examiner 
finds that the improvement is related to the ability to work and 
proceeds to step six of the evaluation process. If the current 
assessment does not show improvement, then the disability examiner 
proceeds to step five. 

The fifth step is to determine whether an exception to medical 
improvement applies. The law provides for certain limited situations 
when the DDS may discontinue a recipient's benefits even though medical 
improvement has not occurred. The specific group I exceptions are (a) 
the individual is the beneficiary of advances in medical or vocational 
therapy or technology (related to the ability to work), (b) evidence 
shows that the individual has undergone vocational therapy (related to 
the ability to work), (c) evidence shows that, based on new or improved 
diagnostic or evaluative techniques, the individual's impairment(s) is 
not as disabling as it was considered at the time of the CPD, and (d) 
evidence shows that any prior determination or decision was in error. 
If an exception applies, the examiner continues through to step six of 
the evaluation process.[Footnote 39] If an exception does not apply, 
benefits are continued. 

The sixth step is to determine if the current impairments are severe. 
At this step, the examiner considers all of the beneficiary's 
impairments--those present at the previous decision as well as any new 
impairments found in the current review. If the DDS determines that the 
beneficiary's current impairment(s) is not severe, benefits are 
discontinued without further development. If it is determined that the 
impairment(s) is severe, then the examiner considers the impact of the 
beneficiary's impairment(s) on his or her ability to function. This 
consideration will result in a current residual functional capacity 
(RFC) assessment that shows the beneficiary's ability to do basic work 
activities and the evaluation continues to the seventh step. 

The seventh step is to determine whether the beneficiary has the 
capacity to do the work that he or she did before having a disability. 
If the beneficiary has the ability to do past work, then benefits are 
discontinued. If the beneficiary does not have the ability to do work 
he or she has done in the past, the evaluation continues to the eighth 
step. 

The eighth step is to determine if the beneficiary has the ability to 
do other work. At this step, the disability examiner considers the 
complete vocational profile (the beneficiary's age, education, and past 
relevant work experience) together with the beneficiary's RFC to 
determine if he or she has the ability to do other work. If the 
beneficiary has the ability to do other work, disability benefits are 
discontinued. If he or she does not have the ability to do other work, 
benefits are continued.

Comments On The Government Accountability Office (GAO) Draft Report, 
"Disability Programs: Clearer Guidance Could Help SSA Apply The Medical 
Improvement Review Standard More Consistently" (GAO-07-08): 

Thank you for sharing the draft report with us for comment. 

We agree with GAO that our medical improvement review standard (MIRS) 
regulatory framework, and present-day application of such framework, 
protects beneficiaries' rights. We also agree with GAO that we should 
provide refresher training on MIRS to ensure consistent adjudication in 
all MIRS cases. 

We appreciate that the draft report does not make specific 
recommendations about what GAO believes to be the appropriate degree of 
medical improvement necessary to meet the standard or how we should 
provide clarification of the rules for deciding medical improvement. As 
we indicate in several of our more detailed comments below, there is an 
inherent degree of judgment in these determinations, as well as 
virtually limitless variations in case facts, such that it may not be 
possible to quantify a more specific standard that would be meaningful 
and helpful. We also note that GAO gathered survey opinions that might 
suggest lowering the threshold for showing medical improvement; we 
believe that requiring evidence of only de minimis or minor medical 
improvement would arguably circumvent and be contrary to the intent and 
spirit of the MIRS statutory provision. 

Our more detailed comments follow. 

GAO was asked (1) to examine the proportion of beneficiaries who are 
removed from the disability programs because they have medically 
improved and (2) to determine if factors associated with the standard 
pose challenges when determining whether beneficiaries continue to be 
eligible for benefits. With regard to the second request, GAO concluded 
that: 

* Limitations in SSA guidance for assessing medical improvement may 
result in inconsistent application of the standard. 

* SSA guidance regarding the exceptions to the medical improvement 
review standard (MIRS) tends to limit their use and may result in 
benefits continuing for some individuals who may be able to work. 

* There is an incorrect application of one element of the standard, 
specifically that continuing disability reviews (CDRs) should be 
conducted on a neutral basis and without a presumption that an 
individual continues to be disabled. 

* Decisions whether disability ends are limited by inadequate 
documentation of evidence and the judgmental nature of the decision 
process concerning what constitutes medical improvement. 

We address each of these issues in turn, after first commenting on some 
of the statistical data included in the draft report. 

1. The proportion of beneficiaries who are removed from the disability 
programs because they have medically improved and other data in the 
draft report: 

The draft report (on page 5) provides data for the 1981-82 period, when 
about 45 percent of CDRs resulted in termination, which can be 
contrasted with the data provided for the 1999-2005 period (on pages 1 
and 2), when only 2.8 percent of beneficiaries who received a CDR were 
terminated. Presumably, this comparison is intended to illustrate the 
dramatic effect of the change to the MIRS in 1985 as a result of the 
1984 legislation enacted by Congress. However, the 1981-82 period is 
not representative of the results of the CDR process before the MIRS 
standard was introduced. In response to the 1980 Social Security 
amendments and reports that suggested there were many non-disabled 
persons receiving disability benefits, an aggressive effort was 
initiated in 1981 to remove beneficiaries from the DI program whose 
impairments were not severe enough to entitle them to benefits. This 
effort focused on beneficiaries who were deemed at the time most likely 
to be determined not disabled and led to a temporary large increase in 
the number of DI program terminations in the early to mid-1980's. We 
suggest that GAO use a period prior to 1981 for a more appropriate 
comparison of the effects of the two approaches to evaluating 
continuing disability. 

Also, the pie chart on page 12 of the draft report shows that 19 
percent of terminations are due to conversion to retirement benefits 
and 45 percent are due to "other" reasons. However, about 44 percent of 
DI terminations are due to retirement conversion and less than 5 
percent are for "other" reasons, while there is no retirement 
conversion in the SSI program and the most prominent reason for SSI 
terminations is excess income, which accounts for about 60 percent of 
all terminations. We believe that using one pie chart for both programs 
may be misleading and mask program differences. Therefore, we suggest 
that the report include a separate pie chart for each program. 

2. Limitations in SSA guidance for assessing medical improvement may 
result in inconsistent application of the standard: 

The draft report actually seems to make two related recommendations in 
this regard, although only one of them is presented consistently. The 
draft report correctly notes that under the Act we may find that an 
adult's disability has ended only if the evidence establishes both that 
there has been medical improvement and that any medical improvement is 
"related to the ability to work." Under our regulations, these are 
separate inquiries, but the draft report does not consistently state 
whether GAO is recommending that we clarify both policies or just the 
policy for determining if there has been medical improvement. However, 
we were impressed by the extent and variety of opinions GAO was able to 
gather from our Disability Determination Services, Administrative Law 
Judges, and others within the agency who use and interpret our 
instructions and it is clear to us that we should do some training to 
clarify how adjudicators should address these issues. 

Nevertheless, the implication in the draft that any such clarification 
will have a noticeable, if not significant, impact on the number of 
cases in which we find that disability has ended is probably not well 
founded. For example, even if f we were to "clarify" that a relatively 
small change in a sign, symptom, or laboratory finding would be 
sufficient to show that there was medical improvement it would be very 
unlikely that such a small change would be shown to be "related to the 
ability to work" at the next step of the MIRS sequential evaluation 
process or result in a finding that the individual has again become 
able to work. Therefore, unless they are using very high thresholds for 
determining whether there is medical improvement, the fact that some 
DDSs report that they use relatively higher thresholds than 
others[Footnote 40] is unlikely to make a significant difference in the 
number of their determinations that disability has ended.[Footnote 41] 

3. SSA guidance regarding the exceptions to the medical improvement 
review standard tends to limit their use and may result in benefits 
continuing for some individuals who may be able to work: 

The purpose of GAO's recommendation that we provide training on the 
appropriate use of the exceptions was not clear to us. The body of the 
draft report suggests that SSA guidance "appears to discourage and 
limit the use of the exceptions," especially the exception that allows 
a subsequent adjudicator to determine that a prior adjudicator's 
finding of disability (or continuing disability) was in error.[Footnote 
42] The draft reports anecdotal information from adjudicators who may 
have expressed concerns that they were unable to change prior favorable 
decisions in as many cases as they might have liked. 

The draft does not provide a GAO opinion about this finding, nor does 
it indicate that GAO found any evidence that the exceptions are being 
misapplied or not used in situations in which they should be used. 
Therefore, it was not clear what GAO is suggesting we should train 
about, and we suggest that the report explain why GAO believes we 
should provide such training; for example, whether GAO believes that we 
should broaden our interpretation of the error exception and allow 
adjudicators to make findings of decisional error more often or 
encourage them to consider whether prior decisions were in error more 
often than they do now. 

We believe that our implementation of the statutory exceptions to 
medical improvement is appropriate and that our instructions are 
consistent with the intent of the law. We recommend that, in presenting 
this issue in the final report, GAO discuss not only the anecdotal and 
opinion information they gathered but the legislative history of the 
exception provisions and SSA's statements about those provisions in the 
preamble to the publication of the original MIRS regulations in 
1985.[Footnote 43] In the preamble to the final rules, we explained in 
essence that we did intend the exceptions to be true "exceptions"--that 
is, not to be applied routinely--including our reasons for limiting the 
"error" exception in the manner that GAO found and our adjudicators 
reported. A broader application of the error exception could lead to a 
substitution of judgment by an adjudicator for the original finding of 
disability when the person's "medical condition has not changed 
substantially." This quote from the 1984 legislative history indicates 
disapproval of termination for individuals whose medical condition had 
not changed substantially since the time they were awarded benefits. 

4. There is an incorrect application of one element of the standard, 
specifically that continuing disability reviews (CDRs) should be 
conducted on a neutral basis and without a presumption that an 
individual continues to be disabled: 

Based on GAO's findings regarding adjudicator knowledge and application 
of this provision of the statute and our regulations, we agree that 
training is needed and will provide it. However, we would also like to 
comment that the implication in the draft report that better, more 
consistent adjudicator understanding of this provision would result in 
more cessations is unlikely. We believe that the major reasons for the 
provision in the statute were to address the climate of the times: the 
perception that the Agency had gone too far in the early 1980's in 
terminating beneficiaries, perhaps based on a presumption of non- 
disability, and court decisions of the time that held that there was a 
continuing presumption of disability on the other. The conference 
report for the legislation (98-1039, September 19, 1984) explained: 

The conference agreement attempts to strike a balance between the 
concern that a medical improvement standard could be interpreted to 
grant claimants a presumption of eligibility, which might make it 
extremely difficult to remove ineligible individuals from the benefit 
rolls, and the concern that the absence of an explicit standard of 
review or some alternative standard could be interpreted to imply a 
presumption of ineligibility or to allow arbitrary termination 
decisions, which might lead to many individuals being improperly 
removed from the rolls. 

These issues are best addressed by ensuring that the MIRS sequential 
evaluation process is correctly followed. However, we agree with the 
draft that determinations of continuing disability, like determinations 
of initial entitlement, are often inherently subjective so we agree 
that it is appropriate that we take steps to ensure that adjudicators 
approach these cases neutrally, as required by the statue and our 
regulations. 

5. Decisions that disability ends are limited by inadequate 
documentation of evidence and the judgmental nature of the decision 
process concerning what constitutes medical improvement: 

We appreciate the recognition in the draft report that we are taking 
steps to improve the quality of our case development and decisions. The 
report also correctly recognizes that the determinations in many of 
these cases are inherently subjective. It appears that there is no 
additional recommendation in the report regarding these issues.

FOOTNOTES 

[1] In addition to medical CDRs, SSA also conducts "work CDRs" where it 
assesses if an individual's earnings exceeded program limits. Our 
analysis only looked at medical CDRs. It did not include work CDRs. 

[2] Pub. L. No. 98-460 (1984). 

[3] For this report, we refer to "medical improvement" and individuals 
who have "improved medically" as a finding that meets the requirements 
of the medical improvement standard (improvement in a beneficiary's 
medical condition that is related to the ability to work). 

[4] For the purposes of our study, we only assessed DI and SSI adult 
beneficiaries who received a full medical CDR. We did not include 
children or the "age 18 re-determinations" in our analysis since there 
are differences between the medical CDR sequential evaluation processes 
for adults and children. Also, we only assessed the outcome of the full 
medical CDRs. 

[5] During our site visits, we met with 11 CDR supervisors and 
disability examiners who the DDS directors selected as the most 
knowledgeable in their office about the CDR process and the medical 
improvement standard. 

[6] Some disability recipients receive both DI and SSI benefits because 
of the low level of their income and resources. 

[7] Beginning at age 62, workers receiving DI benefits may elect to 
receive retirement benefits in lieu of disability benefits. 

[8] Of these beneficiaries, about 5.7 million were blind or had a 
disability and received about $31.8 billion in benefits. About 1.1 
million beneficiaries did not have a disability, but were aged and 
received about $4.1 billion in benefits. 

[9] SSA officials noted that the discontinuation rate in the early 
1980s may not have been representative of the results of the CDR 
process before the implementation of the medical improvement standard. 
SSA officials stated that in response to reports that suggested that 
many individuals who did not have a disability were receiving benefits, 
an aggressive effort was initiated in 1981 to remove individuals from 
the DI program whose impairments were not severe enough to entitle them 
to benefits. The agency reported that this effort focused on 
beneficiaries who were deemed at the time most likely to be determined 
not to have a disability and led to a large, temporary increase in the 
number of DI program discontinuances in the early to mid-1980s. 

[10] Before disability examiners assess if a beneficiary has improved 
medically, they first assess if the beneficiary is working at the level 
of SGA. If beneficiaries are working at or above the SGA level, then 
benefits are discontinued. If not, then the CDR process proceeds to the 
second step. 

[11] SSA maintains a list of impairments that, by definition, are so 
severe that they are disabling. 

[12] The assessment of a beneficiary's actual ability to work comes 
later in the CDR process (steps 7 and 8). See appendix II for a more 
detailed description of the CDR process. 

[13] At this step of the evaluation, a disability examiner considers 
only the listings that were met (or equaled) the last time the 
beneficiary was evaluated, not all of the listings that existed at the 
time of the last review. 

[14] In addition to the Group I exceptions listed above, benefits may 
also be discontinued if a DI beneficiary is engaging in substantial 
gainful activity. The act also provides for other situations (called 
Group II exceptions) where SSA can discontinue either DI or SSI 
benefits. Group II exceptions are: (a) the prior determination or 
decision was fraudulently obtained, (b) the beneficiary does not 
cooperate with SSA, (c) SSA is unable to locate the beneficiary, and 
(d) the beneficiary fails to follow prescribed treatment which would be 
expected to restore his or her ability to do SGA. For Group II 
exceptions, SSA discontinues benefits immediately without further 
development. 

[15] If beneficiaries' responses to a mailer indicate possible 
improvement in medical condition or vocational status, SSA may refer 
these individuals for a full medical review. However, in most cases, 
SSA decides that a full medical review is not warranted and that 
benefits should be continued. 

[16] Beneficiaries may elect to have benefits continued while they 
appeal the decision that their disability has ended. 

[17] SSA also conducts work CDRs where it may remove a beneficiary from 
the disability programs if their earnings exceed SGA. 

[18] A psychologist may evaluate the evidence if the individual has a 
psychological impairment. 

[19] For the purposes of our study, we only assessed DI and SSI adult 
beneficiaries who received full medical CDRs. We did not include 
children or the "age 18 re-determinations" in our analysis since there 
are differences between the medical CDR sequential evaluation processes 
for adults and children. Also, we only assessed the outcome of the full 
medical CDRs. We did not assess the outcome of the CDR mailers or CDRs 
of beneficiaries' earnings and work activity--referred to as work CDRs. 

[20] The 13,800 people who were removed from the disability programs 
for medical improvement as a result of receiving a CDR represent about 
0.1 percent of all adult DI and SSI disability beneficiaries. Of these 
13,800 recipients, about 9,260 were DI recipients and about 4,580 were 
SSI recipients. 

[21] SSA converts DI beneficiaries to retirement benefits when they 
attain full retirement age. 

[22] The 311,000 recipients who died consisted of about 180,000 DI 
recipients and about 131,000 SSI recipients. 

[23] Beginning at age 62, workers receiving DI benefits may elect to 
receive retirement benefits in lieu of disability benefits. Although 
most beneficiaries receiving DI benefits elect to receive their 
disability benefits until full retirement age--at which time disability 
benefits convert to benefits paid from the Old-Age and Survivors 
Insurance program--some choose to switch earlier. 

[24] For fiscal years 2000 to 2004, in addition to the full medical 
CDRs, SSA also conducted an average of about 834,000 CDR mailers 
annually, ranging from a high of 960,000 mailers in 2000 to a low of 
692,000 mailers in 2003. 

[25] In the late 1990s Congress appropriated special funds for SSA to 
alleviate backlogs of CDRs. These special funds began in fiscal year 
1996 and expired at the end of fiscal year 2002. Because of this 
special funding, the number of full medical CDRs conducted by SSA 
increased. 

[26] We did not determine why the discontinuation rate remained 
consistent considering the change in the number of CDRs conducted. 

[27] See SSA Program Operations Manual System (POMS) section DI 
28010.015. 

[28] While we received 54 completed surveys, not every director 
responded to every question. In presenting our results, we only 
included the directors who answered a particular question with a value 
on our response scale. If a director answered "no basis to judge," we 
did not count that response. 

[29] At this step (step 4 of the CDR evaluation process), the 
assessment of working at the level of SGA is not considered. SGA is 
evaluated in the first step of the CDR evaluation process. See appendix 
II for a detailed description of the CDR process. 

[30] See POMS section DI 28015.320. 

[31] The assessment of a beneficiary's actual ability to work comes 
later in the CDR process (steps 7 and 8). See appendix II for a more 
detailed description of the CDR process. 

[32] During our site visits, we met with 11 CDR supervisors and 
disability examiners who the DDS directors selected as the most 
knowledgeable in their office about the CDR process and the medical 
improvement standard. Seven of these 11 individuals stated that they 
were uncertain about when to apply the exceptions to medical 
improvement. 

[33] The error exception applies when an error was evident in the prior 
decision. 

[34] Of the 48 DDS directors who responded to this question, 17 
indicated that CDR decisions are made on a neutral basis. 

[35] We asked directors to exclude cases missing the entire case file 
(i.e. lost folders) in their responses to this survey question. We 
asked the directors a separate question regarding how frequently or 
infrequently they encounter cases where the entire case file is 
missing. Although SSA has established a new electronic system to 
process initial claims, it has yet to expand this new process to CDRs. 
As a result, CDRs are still being conducted in a paper environment. 

[36] During our site visits, we met with 11 CDR supervisors and 
disability examiners who the DDS directors selected as the most 
knowledgeable in their office about the CDR process and the medical 
improvement standard. 

[37] For SSI beneficiaries, do not consider SGA but skip to the second 
step in the CDR evaluation. 

[38] At this step of the evaluation, a disability examiner considers 
only the listings that were met (or equaled) the last time the 
beneficiary was evaluated, not all of the listings that existed at the 
time of the last review. 

[39] In addition to Group I exceptions, the law provides for additional 
situations (called Group II exceptions) to show that that disability 
discontinues. Group II exceptions are: (a) the individual's prior 
determination or decision was fraudulently obtained, (b) the individual 
does not cooperate with SSA, (c) SSA is unable to find the individual, 
and (d) the individual fails to follow prescribed treatment that would 
be expected to restore his or her ability to do SGA. In these 
situations, SSA discontinues benefits immediately without further 
development. SSA does not determine if medical improvement has occurred 
or if the individual is able to do SGA. 

[40] We noted on page 16 of the draft the statement that, 
"Specifically, 17 of 49 [DDS] directors reported that a large or very 
large increase in a recipient's ability to do basic work activities is 
required; 24 reported that a moderate increase is required; and 8 
reported that a minor or any increase at all is required." However, 
since at least one of the terms ("moderate") used in the question was 
itself vague, it is not clear what standard the DDS administrators had 
in mind when they answered the question, nor do we believe that it 
would be especially helpful to add such terms to our instructions; for 
example, we do not believe it would be significantly better to require 
that there must be a "moderate" improvement in a sign, symptom, or 
laboratory finding to show medical improvement instead of more than 
"minor." It would be difficult, if not impossible, to quantify "the 
degree of improvement required to meet the standard" (draft, page 22) 
in every case. Also, please see the technical comments that follow 
these comments. It appears that the survey question may have improperly 
conflated the policy of "medical improvement" with consideration of the 
ability to do work-related activities. 

[41] In this regard, we note on page 15 of the draft the statement, "Of 
the 52 DDS directors who answered a question in our survey on `minor' 
changes, 21 reported that the practice of disregarding minor changes is 
not an impediment to making a disability determination, while 31 
reported that it is an impediment." The draft draws no inferences from 
this statement, but we must point out that our policy not to consider 
"minor" changes appears to be consistent with the Act's requirement 
that there be "substantial evidence" demonstrating not only that there 
has been "any medical improvement" but that the improvement must be 
related to the ability to work. While a requirement for more than a 
minor change in the individual's medical condition might be an 
"impediment" to a subsequent reviewer's ability to cease entitlement, 
we believe that such a requirement is consistent with legislative 
history of the 1984 amendments indicating disapproval of termination 
for individuals "whose medical condition has not changed substantially 
since they were allowed."
