Why GAO Did This Study: 

The large percentage of Americans that rely on private health 
insurance for health care coverage could expand with enactment of the 
Patient Protection and Affordable Care Act (PPACA) of 2010. Until 
PPACA is fully implemented, some consumers seeking coverage can have 
their applications for enrollment denied, and those enrolled may face 
denials of coverage for specific medical services. PPACA required GAO 
to study the rates of such application and coverage denials. GAO 
reviewed the data available on denials of (1) applications for 
enrollment and (2) coverage for medical services. 

GAO reviewed newly available nationwide data collected by the 
Department of Health and Human Services (HHS) from 459 insurers 
operating in the individual market on application denials from January 
through March 2010. GAO also reviewed a year or more of the available 
data from six states on the rates of application and coverage denials 
and the rates and outcomes of appeals related to coverage denials. The 
six states included all states identified by experts and in the 
literature as collecting data on the rates of application or coverage 
denials and together represented over 20 percent of private health 
insurance enrollment nationally. GAO conducted a literature review to 
identify studies related to application and coverage denials and 
reviewed data from selected studies. GAO interviewed HHS and state 
officials and researchers about factors to consider when interpreting 
the data. 

What GAO Found: 

The available data indicated variation in application denial rates, 
and there are several issues to consider in interpreting those rates. 
Nationwide data collected by HHS from insurers showed that the 
aggregate application denial rate for the first quarter of 2010 was 19 
percent, but that denial rates varied significantly across insurers. 
For example, just over a quarter of insurers had application denial 
rates from 0 percent to 15 percent while another quarter of insurers 
had rates of 40 percent or higher. Data reported by Maryland—the only 
of the six states in GAO’s review identified as collecting data on the 
incidence of application denials—indicated that variation in 
application denial rates across insurers has occurred for several 
years, with rates ranging from about 6 percent to over 30 percent in 
each of 3 years. The available data provided little information on the 
reasons that applications were denied. There are also several issues 
to consider when interpreting application denial rates. For example, 
the rates may not provide a clear estimate of the number of 
individuals that were ultimately able to secure coverage, as 
individuals can apply to multiple insurers, and the rates do not 
reflect applicants that have been offered coverage with a premium that 
is higher than the standard rate. 

The available data from the six states in GAO’s review and others 
indicated that the rates of coverage denials, including rates of 
denials of preauthorizations and claims, also varied significantly. 
The state data indicated that coverage denial rates varied 
significantly across states, with aggregate rates of claim denials 
ranging from 11 percent to 24 percent across the three states that 
collected such data. In addition, rates varied significantly across 
insurers, with data from one state indicating a range in claim denial 
rates from 6 percent to 40 percent across six large insurers operating 
in the state. There are several factors that may have contributed to 
the variation in rates across states and insurers, such as states 
varying in the types of denials they require insurers to report. The 
data also indicated that coverage denials occurred for a variety of 
reasons, frequently for billing errors, such as duplicate claims or 
missing information on the claim, and eligibility issues, such as 
services being provided before coverage was initiated, and less often 
for judgments about the appropriateness of a service. Further, the 
data GAO reviewed indicated that coverage denials, if appealed, were 
frequently reversed in the consumer’s favor. For example, data from 
four of the six states on the outcomes of appeals filed with insurers 
indicated that 39 percent to 59 percent of appeals resulted in the 
insurer reversing its original coverage denial. Data from a national 
study conducted by a trade association for insurance companies on the 
outcomes of appeals filed with states for an independent, external 
review indicated that coverage denials were reversed about 40 percent 
of the time. 

GAO provided a draft of the report to HHS and the Department of Labor 
(DOL). HHS agreed with GAO’s findings, noting the need to improve the 
quality and scope of existing data, and suggested clarifications, 
which were incorporated. HHS and DOL also provided technical comments, 
which were incorporated as appropriate.

The Honorable Kathleen Sebelius: 
Secretary of Health and Human Services: 

The Honorable Hilda L. Solis: 
Secretary of Labor: 

A large majority of Americans--nearly 64 percent as of 2009--rely on 
private insurance for health care coverage, most through employer- 
sponsored group health coverage.[Footnote 1] With the enactment of the 
Patient Protection and Affordable Care Act (PPACA) in March 2010, 
[Footnote 2] enrollment in private health insurance could expand 
significantly, particularly for individuals and families that do not 
have access to group coverage through their employer. While there are 
certain federal requirements protecting against the denial of 
applications for enrollment for individuals eligible for group 
coverage, until PPACA is fully implemented, these protections do not 
apply to some consumers seeking individual coverage from private 
health insurers.[Footnote 3] In addition, once consumers are enrolled 
in either group or individual coverage, coverage can be denied for 
specific medical services, either through a denial of authorization of 
a service before it has been provided or payment for a service that 
has been delivered.[Footnote 4] There are some national data on the 
extent to which applications for enrollment are being denied; however, 
there is not yet any comprehensive, national information on the extent 
to which coverage for medical services is being denied when consumers 
seek health care. The federal government plans to collect additional 
information on the extent of denials of applications for enrollment 
and coverage for medical services and the reasons for those denials, 
with the intent to make it easier for consumers to shop for coverage. 
According to experts, those data may also help with government 
oversight of private health insurance. 

Oversight of private health insurance has been a responsibility of 
state departments of insurance, and states vary in what they require 
of insurers and the degree to which they track insurers' activities, 
including the extent to which insurers are denying applications and 
coverage. The federal government's role in the oversight of private 
health insurance has included, for example, the establishment of 
certain consumer protections for states to enforce. It also includes 
oversight of employer-based coverage performed by the Department of 
Labor (DOL). However, the federal government's role has expanded with 
the enactment of PPACA. PPACA required the Department of Health and 
Human Services (HHS) to begin collecting, monitoring, and publishing 
information on health insurance products. HHS began publishing data 
from insurers on denials of applications for enrollment in October 
2010 and intends to collect data in the future on denials of coverage 
for medical services. 

PPACA directed us to study denials of applications for enrollment and 
coverage for medical services by considering samples of data related 
to such denials, including the reasons for the denials and favorably 
resolved disputes resulting from the denials.[Footnote 5] 
Specifically, we reviewed (1) the data available on denials of 
applications for enrollment and (2) the data available on denials of 
coverage for medical services. 

To describe the data available on denials of applications for 
enrollment--referred to as application denials in this report--we 
reviewed federal, state, and other data including data on the rates of 
and reasons for such denials. First, we reviewed data recently 
collected by HHS from 459 insurers operating in the individual market 
in all 50 states and the District of Columbia.[Footnote 6] The data 
included application denial rates by insurer for a 3-month period--
January through March--in 2010.[Footnote 7] To supplement the single 
calendar quarter of HHS data, we contacted insurance department 
officials in six states regarding data on application and coverage 
denials.[Footnote 8] The six states include all the states identified 
by experts and in the literature as states that collect data from 
insurers on the incidence of application denials, coverage denials, or 
both. Because we did not survey all states to determine whether they 
collect data on the incidence of application or coverage denials, or 
both, there may be other states that collect such data that were not 
known to experts or discussed in the literature.[Footnote 9] Of the 
six states, we identified one, Maryland, that collected data on 
application denials. We reviewed data from Maryland for 2008, 2009, 
and the first half of 2010 on the rate of application denials by 
insurers operating in the individual market in that state. (See 
appendix I for more information about our methodology for selecting 
states and the state data we reviewed.) We also conducted a structured 
literature review to identify studies related to application and 
coverage denials. We determined that a study was directly relevant to 
our objective on application denial data if it included empirical 
analyses of the frequency of application denials.[Footnote 10] Through 
our review, we identified four studies that met our criteria. Two of 
these four studies, produced by America's Health Insurance Plans 
(AHIP), included data on application denial rates in 2006 and 2008, 
and we reviewed those data. (See appendix II for a description of the 
literature review methodology and the list of studies identified 
through the review.) Finally, we interviewed officials from HHS, 
Maryland, and AHIP about factors to consider when interpreting the 
data. We also interviewed officials from three large insurance 
companies about the data they collect on application denials. 
[Footnote 11] 

To describe the data available on denials of coverage for medical 
services--referred to as coverage denials in this report--we reviewed 
state and other data, including data on the rates of and reasons for 
denials and the outcomes of appeals related to denials, such as 
disputes resolved in favor of consumers. First, of the same six states 
we contacted regarding application denial data, we reviewed the most 
recent year of data available on the rate of coverage denials from the 
four that reported collecting such data.[Footnote 12] Second, we 
reviewed data on the outcomes of appeals related to coverage denials 
from all of the six states for the most recent year available. We also 
interviewed officials from departments of insurance and other 
departments involved in overseeing insurance or responding to appeals 
in the six states about considerations for interpreting the data. To 
supplement the information from selected states, we reviewed data 
reported by 49 states and the District of Columbia to the National 
Association of Insurance Commissioners (NAIC) on the number of 
complaints related to coverage denials resolved in 2009 and the 
reasons for and outcomes of those complaints.[Footnote 13] We also 
reviewed information on the outcomes of complaints and appeals 
submitted by 35 states and the District of Columbia to HHS in 
applications for Consumer Assistance Program grants.[Footnote 14] As 
part of our literature review, we identified studies that included 
empirical analyses of the frequency of coverage denials, the reasons 
for such denials, the frequency of appeals of coverage denials, or the 
outcomes of such appeals. Through the review, we identified annual 
studies produced by the American Medical Association (AMA) in 2008, 
2009, and 2010 that included data on the incidence and reasons for 
claim denials. We reviewed data from the 2010 study and interviewed 
AMA officials about factors to consider when interpreting the data. 
Finally, we reviewed data from DOL on complaints related to coverage 
denials for those with employer-sponsored coverage from fiscal year 
2010, including the number and value of financial recoveries made by 
the department on behalf of consumers as a result of complaints. 

To assess the reliability of the data we reviewed on the incidence of 
application and coverage denials, the reasons for such denials, and 
the outcomes of appeals and complaints related to those denials, we 
interviewed federal, state, and other officials about their efforts to 
ensure the quality of the data. This included discussing whether they 
required insurers to certify the accuracy of data reported on the 
incidence of application or coverage denials and what steps were taken 
to ensure the quality of data tracked by states and DOL on the 
outcomes of appeals and complaints related to denials. We also asked 
officials about the limitations of the data and reviewed any 
statements about data limitations in published reports of the data. We 
determined the data to be sufficiently reliable for the purposes of 
describing the (1) denial rates, (2) reasons for denials, and (3) 
outcomes of appeals related to denials indicated by the data; where 
relevant we stated the limitations of the data in the findings. 

We conducted our performance audit from September 2010 through January 
2011 in accordance with generally accepted government auditing 
standards. Those standards require that we plan and perform the audit 
to obtain sufficient, appropriate evidence to provide a reasonable 
basis for our findings and conclusions based on our audit objectives. 
We believe that the evidence obtained provides a reasonable basis for 
our findings and conclusions based on our audit objectives. 

Background: 

In 2009, approximately 156 million nonelderly individuals obtained 
health insurance through their employer and another 16.7 million 
purchased health insurance in the individual market. Of those with 
employer-sponsored group health plans, in 2009, 43 percent were 
covered under a fully insured plan where the employer pays a per-
employee premium to an insurance company.[Footnote 15] The remaining 
57 percent were covered under self-funded plans where instead of 
purchasing health insurance from an insurance company the employer 
sets aside its own funds to pay for at least some of its employees' 
health care.[Footnote 16] 

Application Denials: 

Application denials result when an insurer determines that it will not 
offer coverage to an applicant either because the applicant does not 
meet eligibility requirements or because the insurer determines that 
the applicant is too high of a risk to insure. Underwriting is a 
process conducted by insurers to assess an applicant's health status 
and other risk factors to determine whether and on what terms to offer 
coverage to an applicant. 

Many consumers are protected from having their application for 
enrollment denied. Consumers who obtain health coverage through their 
employment by enrolling in a group health plan sponsored by their 
employer have certain protections against application denials. For 
example, under federal law, individuals enrolling in group health plan 
coverage are protected from being denied enrollment because of their 
health status.[Footnote 17] Under federal law, insurers also generally 
are prohibited from denying applications for individual health 
coverage for certain individuals leaving group health plan coverage 
and applying for coverage in the individual market.[Footnote 18] 

Currently, some consumers who apply for private health insurance 
through the individual market can have their applications denied for 
eligibility reasons or as a result of underwriting. For example, 
applications filed by some consumers with preexisting health 
conditions can be denied, unless prohibited by state or federal law. 
[Footnote 19] Additionally, insurers may accept the application but 
offer coverage at a premium level that is higher than the standard 
rate or that excludes coverage for certain benefits. The options for 
appealing application denials in the individual market can be limited 
to filing a complaint with the state department of insurance. However, 
in 35 states, individuals who--due to a preexisting health condition--
have been denied enrollment or charged higher premiums in the 
individual market are typically eligible for coverage through high-
risk health insurance pools (HRP).[Footnote 20] Additionally, as 
required under PPACA, individuals who have preexisting health 
conditions and have been uninsured for 6 months are eligible for 
enrollment in a temporary national HRP program.[Footnote 21] 

Coverage Denials: 

Coverage for medical services can be denied before or after the 
service has been provided, either through denial of preauthorization 
requests or denial of claims for payment. As a condition for coverage 
of some services, providers or consumers are required to request 
authorization prior to providing or receiving the service. 
Preauthorization denials occur when a determination is made that (1) 
the consumer is not eligible to receive the requested service, for 
example, because the service is not covered under the individual's 
policy, or (2) the service is not appropriate, meaning that it is not 
medically necessary or is experimental or investigational. Denials of 
claims occur for various reasons. Claims may be denied for billing 
reasons, such as the provider failing to include a piece of required 
information on the claim, such as documentation that the provider 
received preauthorization for a service, or submitting a duplicate 
claim. Claims may also be denied because of eligibility issues. For 
example, a claim may be submitted for a service provided before an 
individual's coverage began or after it was terminated, or a claim may 
be submitted for a service that has been excluded from coverage under 
an individual's policy. Another reason for denials reported by some 
insurers is that the individual has not met the cost-sharing 
requirements of his or her policy, such as the required deductible. 
Finally, claim denials can occur when a determination is made that the 
service provided was not appropriate, specifically that the service 
was not medically necessary or was experimental or investigational. 
Depending on the reason for a claim denial, either the provider or the 
consumer may bear the financial responsibility for the denied coverage 
amount. Claims that are denied because of such billing errors as the 
provider not providing a required piece of information can be 
resubmitted and ultimately paid. 

For claim denials, the full claim may be denied or, if the claim 
contained multiple lines, such as a surgery with charges for multiple 
procedures and supplies, only certain lines of the claim may be 
denied. How insurers and self-funded group health plans track claim 
denials and the reasons for denials may vary. For example, AMA 
officials noted that there is no guidebook for how reason codes should 
be assigned to claim denials. Officials noted that denials are often 
assigned the code for the most general reason even though the denial 
may be for a more specific reason. 

Consumers have several avenues available to dispute coverage denials. 
First, consumers can file an appeal of a denial with the insurer or 
self-funded group health plan for review, referred to as an internal 
appeal. Internal appeals can result in the denial being upheld or 
reversed. In addition, consumers in most states can have their appeal 
reviewed by an external party, such as an independent medical review 
panel established by the state.[Footnote 22] These appeals, referred 
to as external appeals, can also result in denials being reversed and 
in states recovering funds for consumers for the cost of the denied 
service. State external appeal options may only be available once the 
consumer has exhausted the internal appeal process or for consumers 
with certain types of coverage. Historically, those with self-funded 
group health plans generally did not have access to an external appeal 
process, but consumers could file suit against a health plan in court 
to challenge a denial. PPACA, however, required that group health 
plans, including self-funded plans, provide access to an external 
appeal process that meets federal standards for plan years beginning 
on or after September 2010.[Footnote 23] Finally, consumers may file 
complaints regarding coverage denials with the state, generally the 
department of insurance, or, for those with group health plans, with 
DOL. Filing a complaint can be a less formal mechanism for disputing a 
coverage denial than filing an appeal; however, complaints can result 
in reversals of denials and in financial recoveries for consumers. 

State and Federal Oversight of Private Health Insurance: 

States have responsibility for regulating private health insurance, 
including insurers operating in the individual market and the fully 
insured group market. In overseeing insurer activity, states vary in 
the data they require insurers to submit on denials and internal 
appeals of denials. According to NAIC officials, few states require 
insurers to report data regularly on the frequency of denials and 
internal appeals, and NAIC has not issued any model laws or 
regulations that include requirements for insurers to report such 
data. States also may use data on complaints and external appeals to 
identify trends in the practices of insurers and target examinations 
of specific insurers' practices. Nearly all states and the District of 
Columbia regularly report complaint data, which includes information 
on the numbers of, reasons for, and outcomes of complaints, to NAIC. 

Historically, the federal government's role in oversight of private 
health insurance has included establishing requirements for states to 
enforce. For example, the Health Insurance Portability and 
Accountability Act of 1996 (HIPAA) established consumer protections on 
access, portability, and renewability of coverage.[Footnote 24] In 
addition, with respect to group health plans, the federal government 
enforces disclosure, reporting, fiduciary, and claims-filing 
requirements under the Employee Retirement Income Security Act of 1974 
(ERISA).[Footnote 25] DOL conducts a number of efforts to enforce the 
ERISA requirements. For example, the department conducts civil 
investigations that can result in corrective actions, such as monetary 
recoveries for consumers who are enrolled in employment-based plans. 
In addition to these formal methods, DOL also works to resolve 
complaints filed with the department. These efforts are considered 
informal resolutions, although complaints can also serve as a trigger 
for formal enforcement actions. 

PPACA expanded the federal oversight role by requiring HHS to begin 
collecting, monitoring, and publishing data from certain insurers. 
Specifically, PPACA required the establishment of an internet Web site 
through which individuals can identify affordable health insurance 
coverage options in their state.[Footnote 26] To implement this 
requirement, in May 2010, HHS issued an interim final rule requiring 
insurers in the individual and small group markets to submit data to 
HHS on their products, including data on the number of enrollees, 
geographic availability of the products, and customer service contact 
information, by May 21, 2010, and annually after that.[Footnote 27] In 
July 2010, HHS began publishing these data on the new Web site, which 
is designed for individuals and small businesses to obtain information 
on coverage options available in their state. In October 2010, HHS 
began posting additional data collected from insurers, including data 
on the percentage of applications denied for each product offered in 
the individual market. The interim final rule also required insurers 
to submit other data, such as data on the percentage of claims denied 
in the individual and small group markets, and the number and outcomes 
of appeals of denials to insure, pay claims, and provide 
preauthorization, in accordance with guidance to be issued by HHS. As 
of December 2010, HHS had not issued any guidance on reporting these 
additional data. 

Federal, State, and Other Data Indicated Variation in Application 
Denial Rates and Provided Little Information on the Reasons for 
Denials: 

Nationwide data from HHS showed variation in application denial rates 
across insurers operating in the individual market. Specifically, data 
collected by HHS from 459 state-licensed insurers on the number of 
applications received and denied from January through March 2010 
indicated that, while the aggregate rate of application denials was 19 
percent nationally, the rate varied significantly across insurers. For 
example, just over a quarter of insurers had application denial rates 
from 0 percent to 15 percent while another quarter of insurers had 
rates of 40 percent or higher.[Footnote 28] However, the insurers with 
rates of 40 percent or higher reported fewer applications. See table 1 
for additional information on the range in application denial rates 
across insurers. 

Table 1: Range of Application Denial Rates among State-Licensed 
Insurers, Based on HHS Data, January-March 2010: 

Application denial rates (percentage of applications denied): 0 to 15; 
Number of insurers reporting rates in range[A]: 132; 
Number of applications received[B]: 499,239. 

Application denial rates (percentage of applications denied): 16 to 23; 
Number of insurers reporting rates in range[A]: 102; 
Number of applications received[B]: 471,878. 

Application denial rates (percentage of applications denied): 24 to 39; 
Number of insurers reporting rates in range[A]: 113; 
Number of applications received[B]: 230,846. 

Application denial rates (percentage of applications denied): 40 or 
higher; 
Number of insurers reporting rates in range[A]: 112[C]; 
Number of applications received[B]: 57,923. 

Source: GAO analysis of HHS data. 

[A] Data were reported to HHS by 459 state-licensed insurers operating 
in 50 states and the District of Columbia. Data on insurers operating 
in states with guaranteed issue requirements that prohibit any insurer 
from denying coverage to an individual based on his or her current 
medical conditions or risk of poor health were included in the 
analysis. 

[B] Insurers were instructed to report the number of applications 
received for products offering comprehensive medical coverage. HHS 
officials told us that they identified instances where insurers 
included data on applications for more limited products, such as one 
that covers only hospital services. The application data may also 
include applications for products being sold for only a portion of the 
3-month period. 

[C] The data indicated that two insurers had denial rates of 100 
percent and each of these insurers reported receiving one application 
in the 3-month reporting period. 

[End of table] 

HHS officials noted that the data the department collected on 
application denials, which represent a single calendar quarter of 
applications, are only a starting point. They told us that as insurers 
report additional quarters of data, the value and usefulness of the 
data will increase. In addition, officials said that they have taken 
steps to ensure the accuracy of the data and noted that the accuracy 
of these data is critical to HHS, because no other source of 
information on private health insurance has a complete catalog of 
insurers operating in the individual market and what products those 
insurers are selling. 

Data reported by Maryland--the only state we identified as collecting 
data on the incidence of application denials--indicated that variation 
in application denial rates across insurers operating in the state's 
individual market has occurred in that state for several years. 
Maryland data showed that the range of application denial rates across 
insurers was 26 percentage points or more in each of three reporting 
periods, 2008, 2009, and the first half of 2010. (See table 2 for the 
range in denial rates in the data reported by Maryland.)

Data reported in studies by AHIP also showed variation in application 
denial rates. The AHIP data illustrated that application denial rates 
varied across age groups, with denial rates increasing as the age of 
the primary applicant increased. In 2008, when AHIP data showed that 
13 percent of all medically underwritten applications were denied, 
[Footnote 29] in general the denial rate progressively increased as 
the applicant's age increased, from a low of 5 percent for applicants 
under 18 years of age to a high of 29 percent for applicants from 60 
to 64 years of age.[Footnote 30] Similar variation in AHIP application 
denial rates was seen in data from 2006.[Footnote 31] (See figure 1.)

The available data on application denial rates provided little 
information on the reasons that applications were denied. For 
instance, the HHS and Maryland data did not include any information on 
the reasons for application denials. The AHIP data, however, provided 
limited information. Specifically, AHIP's data showed that a higher 
percentage of applications were denied because of the applicant's 
health status than for nonmedical reasons, such as the plan not being 
offered in the applicant's geographic area. AHIP data showed that in 
2008, of the 1.8 million applications for enrollment that insurers 
either denied or made offers of coverage, 1 percent were denied for 
nonmedical reasons and 12 percent were denied after underwriting when 
the applicant's health status and other risk factors were assessed. 
According to an AHIP official, applications that were denied after 
underwriting were presumably denied because the applicant's medical 
questionnaire responses were beyond the insurer's threshold for 
issuing a policy. 

There are several issues to consider when interpreting application 
denial rates. First, application denial rates may not provide a clear 
estimate of the number of individuals that were ultimately able to 
secure health coverage, because individuals may submit applications 
with more than one insurer and be denied by one insurer but offered 
enrollment by another. Second, denial rates also do not reflect 
applications that have been withdrawn. For example, AHIP data for 2008 
indicated that 8 percent of applicants withdrew their applications 
before underwriting occurred. Experts also noted that some individuals 
may not submit applications for health coverage because they believe 
or have been advised, for example by an insurance agent, that their 
application would likely be denied. Third, an insurer's denial rates 
may be affected by requirements of the states in which the insurer 
operates. For example, officials from one insurance company explained 
that for applicants in the state for which they are the insurer of 
last resort, state law prohibits them from denying applications for 
enrollment based on the health status of the applicant.[Footnote 32] 
Officials told us that a denial can occur only for nonmedical 
eligibility reasons, which the AHIP data indicate are far less 
frequent. 

Another consideration when interpreting application denial rates is 
that the rates do not reflect applications that have been accepted by 
an insurer but for coverage with a premium that is higher than the 
standard rate or with exclusions for coverage of specified services. 
Data from HHS, Maryland, and AHIP all indicated that some portion of 
applicants received offers at a premium that was higher than the 
standard rate. For example, the HHS data demonstrated that from 
January through March of 2010, about 20 percent of individual market 
applicants were offered coverage with premiums higher than the 
standard rate. Maryland data also indicated that for the first half of 
2010, 8 percent of applicants were offered either coverage with 
premiums higher than the standard rate or coverage that excluded 
specified health conditions. Finally, AHIP data from 2008 showed that 
34 percent of offers for coverage were for coverage at a higher 
premium rate. The AHIP data also showed that 6 percent of offers for 
coverage were for coverage that excluded specified health conditions. 

State and Other Data Indicated That Coverage Denial Rates and the 
Reasons for Denials Vary and That Denials, If Appealed, Are Often 
Reversed: 

Data from selected states and others indicated that the rates of 
coverage denials, including denials for preauthorizations and claims, 
varied significantly, and a number of factors may have contributed to 
that variation. The data also indicated that coverage denials occurred 
for a variety of reasons, frequently for billing errors and 
eligibility issues and less often for judgments about the 
appropriateness of a service. Further, the data we reviewed indicated 
that coverage denials, if appealed, were frequently reversed in the 
consumer's favor and that appeals and complaints related to coverage 
denials sometimes resulted in financial recoveries for consumers. 

State and Other Data Indicated Wide-Ranging Coverage Denial Rates, and 
a Number of Factors May Have Contributed to This Variation: 

State data that we reviewed showed that rates of coverage denials by 
insurers operating in the group and individual markets varied 
significantly across states. Specifically, aggregate claim denial 
rates for the three states that we identified as collecting such data 
ranged from 11 percent in Ohio in 2009 to 24 percent in California in 
the same year.[Footnote 33] Data reported by the remaining state, 
Maryland, indicated a claim denial rate of 16 percent in 2007. 
[Footnote 34] A fourth state, Connecticut, collected data on a 
different measure, preauthorization denials, and these data indicated 
a denial rate of 14 percent in 2009.[Footnote 35] In addition, claim 
denial rates indicated by AMA data--3 percent during 2 months of 2010--
varied from coverage denial rates in the four states.[Footnote 36] 

Several factors may have contributed to the variation in rates across 
the four states and the AMA data. For example, Ohio and AMA data were 
based on denials of electronic claims.[Footnote 37] AMA officials told 
us that providers with electronic billing systems and insurers that 
accept electronic claims are more sophisticated in terms of billing 
management, and therefore the denial rates calculated by AMA may be 
lower than rates of denials for all claims, including both electronic 
and paper-based. In another example, Maryland's rate was calculated 
using data for categories of denials that accounted for about 90 
percent of all claims denied. In contrast, according to California 
officials, California's data represented all claim denials. [Footnote 
38] Differences in the time frames for the data may have also 
contributed to the variation. AMA officials noted that their data were 
from a 2-month period of the year (February through March) when there 
was less contractual activity, such as open enrollment periods, and 
when denials related to meeting deductible requirements--which 
according to officials from one insurance company can be significant--
have already been resolved. In contrast, data from the four states, 
except Ohio, covered a full year and therefore reflect all denials for 
the year, including those related to enrollment and deductible issues. 
See table 3 for the rates of coverage denials indicated by state data 
and a description of the characteristics of the data, some of which 
may have contributed to the variation in rates. 

Table 3: Rates of Claim or Preauthorization Denials across States in 
GAO's Review and Characteristics of the State Data: 

State: Ohio; 
Rate of claim or preauthorization denials: 11 percent across all 
insurers licensed in the state; 
Data year[A]: 2009; 
Characteristics of the data: Data limited to denials of electronic 
claims in the first and third quarters of the fiscal year[B]. 

State: Connecticut; 
Rate of claim or preauthorization denials: 14 percent across 21 
managed care organizations licensed in the state; 
Data year[A]: 2009; 
Characteristics of the data: Data were limited to denials of 
preauthorization for services and did not include data on denials of 
claims[C]. 

State: Maryland; 
Rate of claim or preauthorization denials: 16 percent across 41 
insurers licensed in the state; 
Data year[A]: 2007; 
Characteristics of the data: Data were limited to 16 categories of 
denials of claims, representing 90 percent of total claim denials[D]. 

State: California; 
Rate of claim or preauthorization denials: 24 percent across six of 
the largest managed care organizations licensed in the state; 
Data year[A]: 2009; 
Characteristics of the data: Data were limited to denials of claims 
and reflected each insurer's inventory of denials, which means that 
some insurers may have reported denials for government-sponsored 
health coverage, such as Medicaid[E].

[End of table] 

In addition to variation across states in aggregated rates, state and 
other data also indicated that coverage denial rates varied 
significantly across insurers. For example, the California data 
indicated that in 2009 claim denial rates ranged from 6 percent to 40 
percent across six of the largest managed care organizations operating 
in the state. Similarly, preauthorization denial rates in Connecticut 
varied across 21 insurers, with rates among the seven largest insurers 
ranging from 4 percent to 29 percent in 2009. Somewhat narrower 
variation across insurers was also evident in the AMA data, with claim 
denial rates in 2010 that ranged from less than 1 percent to over 4 
percent across the seven insurers represented in those data.[Footnote 
39] 

State and other officials told us about several factors that may have 
contributed to the variation across insurers and make it difficult to 
compare data across insurers. First, California officials told us that 
insurers may interpret a state's reporting requirements differently 
and noted that some insurers may count certain claims transactions as 
denials that the state would not consider a denial. This was evidenced 
by discussions with one insurer who told us that if asked to report 
the number of claims denied, some insurers might include claims where 
the service was approved but the insurer paid nothing because the 
member was liable for the charge, which California officials would not 
characterize as a denial. Officials from the insurer said that their 
current overall denial rate is 27 percent, but it would be 18 percent 
if member liability denials were excluded. Officials from California 
and AMA also indicated that circumstances unique to an insurer may 
affect their denial rate. For example, California officials told us 
one insurer's denials rose sharply in a month because providers were 
submitting claims to the insurer's HMO when they should have gone to 
the preferred provider organization (PPO). Rather than transferring 
the claims, the HMO denied all of them, and then the PPO paid the 
claims shortly after that. 

State and Other Data Indicated That Coverage Denials Occurred for 
Various Reasons and That Denials, If Appealed, Were Frequently 
Reversed: 

According to state and other data, coverage denials occurred for 
various reasons. For example: 

* Claim denials were often made for billing errors such as duplicate 
claims and missing information on the claim. For example, data from 
Maryland showed that the most prevalent reason for claim denials in 
2007 was duplicate claim submissions, accounting for 32 percent of all 
denials.[Footnote 40] Among six of the largest managed care 
organizations in California, the four that reported on the most 
prevalent reasons for claim denials in 2009 all reported duplicate 
claims as one of those reasons. With regard to claims missing required 
information, the 2010 AMA data indicated that five of the seven 
insurers represented in the data made 15 percent or more of denials on 
the basis that the claim was missing information, such as 
documentation of preauthorization. Data from Maryland showed that 74 
percent of denied claims did not meet the state's criteria for "clean" 
claims, those claims that include all of the required information 
needed for processing.[Footnote 41] 

* Denials of claims also frequently resulted from eligibility issues. 
For example, for six of the seven insurers in the 2010 AMA data, over 
20 percent of claim denials occurred as a result of eligibility issues 
such as services being provided before coverage was initiated or after 
coverage was terminated. 

* Insurers also denied preauthorizations and claims as a result of 
judgments about the appropriateness of the service, such as that the 
service was not medically necessary or was experimental or 
investigational, although less frequently than for billing errors and 
eligibility issues. Data from Maryland showed that in 2007 insurers 
denied nearly 40,000 preauthorizations or claims because they 
determined the services were not medically necessary.[Footnote 42] 
This was a relatively small number compared to the 6.3 million claim 
denials reported in the same year.[Footnote 43] The 2010 AMA data 
showed that only one of the seven insurers denied claims on the basis 
that services were not appropriate, specifically that the service was 
experimental or investigational, with about 9 percent of denials made 
for that reason.[Footnote 44] NAIC data on complaints filed with 
states in 2009 also provided some information on coverage denials 
related to the appropriateness of services. Specifically, the data 
showed that of the approximately 14,000 complaints related to coverage 
denials, at least 8 percent were related to the insurer's 
determination that the service was not medically necessary and 2 
percent were related to the determination that the service was 
experimental. 

State and other data indicated that coverage denials, if appealed, 
were frequently reversed in the consumer's favor.[Footnote 45] The 
data from the four states that we identified as collecting data on the 
outcomes of internal appeals filed with insurers indicated that at 
least 39 percent of internal appeals resulted in the insurer reversing 
its original coverage denial. Officials from two insurance companies 
explained that denials are frequently reversed because the consumer or 
provider submits additional information, such as the consumer's 
medical records. Officials from one of these insurance companies also 
explained that because insurers receive additional information through 
the appeals process, reversals of denials are expected even when the 
company is using accepted medical criteria to make the initial 
assessment of the appropriateness of the service; and regulators are 
sometimes concerned when few appeals result in reversals of denials. 
See table 4 for a summary of the outcomes of internal appeals reported 
by insurers to Connecticut, Maryland, New York, and Ohio.

Data on the results of appeals filed with states for external review 
also indicated that denials were frequently reversed. A study 
conducted by AHIP on 37 states' external appeal programs showed that 
for 2003 and 2004, about 40 percent of external appeals resulted in 
denials being reversed.[Footnote 46] More recent data from the six 
states we contacted indicated similar rates of denials being reversed 
upon external appeal. See table 5 for a summary of the outcomes of

frequently reversed than denials because the service was not 
appropriate. 

[End of table] 

The data on the outcomes of external appeals also indicated that the 
rate at which denials are reversed, if appealed, may vary depending on 
the reason for the denial and the type of service denied. For example, 
one study identified through our literature review looked at 740 
external appeal decisions in California in 2001 and 2002. The study 
showed that appeals resulted in denials being reversed in 42 percent 
of cases where the denial resulted from the determination that 
services were not medically necessary and 20 percent of cases where 
services were determined to be experimental and investigational. 
[Footnote 47] Further, the study showed that reversals of denials were 
more likely for certain services, such as gastric bypass surgery, stem 
cell transplants, and breast reduction surgery, than for other 
services, such as residential behavioral health care. Data from 
Florida also indicated variation in outcomes of external appeals based 
on the reason for the denial and the type of service denied. For 
example, for state fiscal year 2010, denials were reversed in 49 
percent of cases where the denial resulted from the determination that 
services were not medically necessary and in 60 percent of cases where 
the service was deemed experimental or investigational, although there 
were fewer appeals of coverage denials for this reason.[Footnote 48] 
Further, the data showed that appeals were more likely to result in a 
denial being reversed when the denial was for diagnostic testing and 
pharmaceuticals than for other services, such as cosmetic surgery and 
durable medical equipment. 

Finally, federal and state data indicated that appeals and complaints 
related to coverage denials sometimes resulted in financial recoveries 
for consumers. According to data from DOL, more than 9,600 complaints 
related to coverage denials by group health plans resulted in about 
500 recoveries of payments totaling nearly $7 million in fiscal year 
2010. Data reported by states to HHS in applications for the Consumer 
Assistance Program grants also documented that complaints and appeals 
resulted in recoveries.[Footnote 49] Specifically, 21 of the 35 states 
submitting applications reported financial recoveries. For example, 
Maryland reported recovering more than $1.4 million for consumers in 
fiscal year 2009 as a result of internal appeals. NAIC data on 
complaints filed with states also gave some indication of recoveries. 
For example, NAIC's 2009 data indicated that of the approximately 
14,000 complaints related to coverage denials, over 4 percent resulted 
in an outcome where money or benefits were returned to the consumer 
and about 7 percent resulted in the insurer paying more of a claim 
than was initially paid. 

Agency Comments and Our Evaluation: 

HHS provided us with written comments on a draft version of this 
report. These comments are reprinted in appendix III. HHS agreed with 
our findings, noting in particular the need to improve the quality and 
scope of existing data, and suggested clarifications, which we 
incorporated. HHS and DOL also provided technical comments to the 
draft report, which we incorporated as appropriate. 

In its written comments, HHS emphasized the importance--for 
policymakers, regulators, and consumers--of data on health insurance 
application and coverage denials. HHS noted that data on application 
and coverage denials can help increase transparency in the private 
health insurance market and that these data can also provide an 
important baseline measure for evaluating the impact of changes 
resulting from PPACA. In its comments, HHS also noted that data 
collection on application and coverage denials has been uneven across 
insurers, plans, and states and that very little information is 
available to help analysts understand the causes or sources of 
variation in the data that are available. According to HHS, more 
effort is needed to improve the quality and scope of existing data 
collection to give policymakers and regulators better and richer data 
to evaluate health insurance plan practices and market changes and to 
produce measures that may be useful to consumers when they are 
shopping for insurance. 

In its written comments, HHS also identified a limitation to our data 
that needed some clarification. Specifically, HHS pointed out-- 
correctly--that while our draft report provided information on the 
percentage of claims that were denied, as well as data on the outcomes 
of internal appeals and external reviews of denied claims, our draft 
report did not provide data on the frequency with which claim denials 
are appealed by consumers. These data were not included in the report 
because the data we reviewed did not allow for a systematic 
calculation of an "appeal rate"--the number of coverage denials for 
which an appeal was initiated--for several reasons, including 
different sources or years of denials and appeals data we reviewed. In 
response to HHS' comments, we added language to the report clarifying 
this limitation. For context, we also added information on the appeal 
rate from one quarter for one state--the only information we 
identified on internal claims appeal rates. HHS also noted that the 
statement in our draft report that "denials are frequently reversed" 
upon appeal may be confusing, because readers may assume a large 
number of claim denials are ultimately overturned. We revised the 
language in our draft report to prevent this misinterpretation of our 
data, by stating that coverage denials, if appealed, were frequently 
reversed in the consumer's favor. 

We are sending copies of this report to the Secretaries of HHS and 
DOL, the congressional committees of jurisdiction, and other 
interested parties. In addition, the report is available at no charge

Appendix I: Methodology for Selecting States and State Data Reviewed by 
GAO: 

In order to describe the data on denials of applications for enrollment 
and coverage of medical services, we contacted six states to interview 
officials and to obtain data the states collect and track on denials 
and appeals related to denials. The six states we selected included 
states identified in the literature, through searches of state 
insurance department Web sites, or in interviews with experts as a 
state collecting data on the incidence of application or coverage 
denials.[Footnote 50] These also included states that collect or track 
data on appeals related to coverage denials reviewed by insurers 
(internal appeals) or reviewed by external parties (external appeals). 
The six states accounted for at least 20 percent of national enrollment 
in private health insurance. 

Once we selected the states, we asked officials from each state whether 
they collected the following types of data: (1) incidence of 
application denials; (2) incidence of coverage denials, including 
incidence of denials of preauthorizations and claims; (3) incidence and 
outcomes of appeals reviewed by insurers (that is, internal appeals); 
and (4) incidence and outcomes of appeals reviewed by external parties 
(that is, external appeals). If state officials reported collecting the 
data, we reviewed at least the most recent year of data available. We

Appendix II: Methodology for and Studies Identified by Structured 
Literature Review: 

To identify research that examined private health insurance denials, 
including the incidence of denials of applications for enrollment and 
of coverage for medical services (i.e., "coverage denials") and the 
incidence and outcomes of appeal related to coverage denials, we 
conducted a structured literature review. This review resulted in 24 
studies that we determined to be relevant to our objectives. To conduct 
this review, we searched 23 reference databases for articles or studies 
published from January 2000 through July 2010,[Footnote 51] using a 
combination of search terms, such as "denial" and "insurer."[Footnote 
52] We determined that a study was directly relevant to our objectives 
if it: (1) included empirical analysis related to the incidence of 
application denials, the incidence of coverage denials, or the 
incidence and outcomes of appeals related to such denials; and (2) 
analyzed, at minimum, denial or appeal data from an entire state or two 
or more insurers. In addition to searching the reference databases, we 
checked the bibliographies of the relevant studies to identify other 
potentially relevant research and interviewed several private health 
insurance experts about research done on denials. 

We identified 24 studies in the literature that included empirical 
analyses examining (1) the frequency of denials of applications for 
enrollment or (2) the frequency of or reasons for denials of coverage 
for medical services and outcomes of appeals related to such denials. 
Table 7 identifies the number of studies that address these topics, 
with some studies addressing more than one topic.

General Comments Of The Department Of Health And Human Services (HHS) 
ON THE GOVERNMENT ACCOUNTABILITY OFFICE'S (GAO) Draft Report Entitled, 
"Private Health Insurance: Data On Application And Coverage Denials" 
(GAO-I1-268): 

The Department appreciates the opportunity to review and comment on 
this draft report. 

The Affordable Care Act (ACA) of 2010 required GAO to study the rates 
of such application and coverage denials. GAO reviewed the data 
available on denials of the applications of enrollment and coverage 
for medical services. 

We would like to emphasize the importance-—for policy makers, 
regulators and consumers—-of the data presented in your report, and 
make note of Center for Consumer Information and Insurance Oversight's 
(CCIIO) role in improving and expanding data collection on application 
and coverage denials to help bring about increased transparency in 
private health insurance. 

We would like to also bring your attention to an important piece of 
data not included in your analysis. Although GAO's draft report 
provides information on the percentage of claims that are denied by 
private health insurance plans, as well as data on the outcomes of 
internal appeals and external review of denied claims, it does not 
provide data on the frequency with which claims denials are appealed 
by consumers. This letter offers views on why the gap matters and what 
might be done to close that data gap. It also highlights HHS' role, 
together with our Federal partners in the Departments of Labor (DoL) 
and Treasury, in crafting federal regulations to both create more 
uniform federal protections for internal appeals and external review 
and enforce notice requirements so that consumers are aware of their 
appeal rights, as required by the ACA. 

Why the Data on Application and Coverage Denials Matter: 

Data on application and coverage denials help increase transparency in 
private health insurance. However, more effort is needed to improve 
the quality and scope of existing data collections to give 
policymakers and regulators better and richer data to evaluate health 
insurance plan practices and market changes, and to produce measures 
that may be useful to consumers when they are shopping for insurance. 

The GAO's draft report makes it abundantly clear that data collection 
on application and coverage denials have been uneven across insurers 
and plans and across states. The report also reveals that very little 
information is available to help analysts understand the causes or 
sources of variation in the data that are available. For example, the 
GAO analyzed data—collected by CCIIO and displayed in the individual 
market plan finder on HealthCare.gov—on applications denials by plans 
in the individual health insurance market. The data perform an 
important function—alerting consumers to the uncertainty that goes 
along with applying for private coverage in the current market. The 
data also provide an important baseline measure for evaluating the 
impact of the ACA. We should, for example, expect to see a sharp 
reduction in these application denials over time, since denials for 
pre-existing conditions will be a thing of the past after 2014. 

Similarly, the GAO's analysis of claims denials primarily serves to 
illustrate that there is variation across issuers. Unfortunately, not 
much more can be said about these data. Although the data illustrate 
wide variation in the reported rate of claims denial, the GAO was 
unable to describe the sources or significance of that variation. 
Further, it is possible that the states that do provide data are also 
the states with stronger appeals protections such that the reported 
rates are not representative of the national picture. 

The GAO report also reveals that the scope of existing data collection 
needs to be expanded to assure transparency across the health 
insurance market. 

How Often Do Consumers Appeal Claims Denials and What Obstacles Do 
They Face? 

Together with our Federal partners in DOL and Treasury, HHS has 
crafted Federal regulations to create more uniform Federal protections 
for internal appeals and external review and to implement improved 
notice requirements for consumers. In order for the Departments to 
provide oversight for those new protections, data on the rate at which 
claims denials are appealed (and the outcomes of those internal 
appeals and external reviews) are needed. 

ACA directed the GAO to study data on denials including denials where 
a "health plan later approves such coverage." Unfortunately, due to 
the limitations of existing data collections, the GAO, with one small 
exception, was not able to report data on the frequency with which 
claims denials are appealed in any segment of the market. 
Consequently, the GAO risks confusion when it states that "denials are 
frequently reversed." Readers may reasonably assume that a large 
percentage of claim denials are ultimately overturned (with a consumer 
receiving a previously denied benefit payment). It is unclear that 
this is the case, especially in the pre-ACA patchwork of appeals 
protections. For example, in its own discussion, the GAO seems to 
suggest that reversals and recoveries for consumers may be rare, 
citing a favorable outcome for a plan enrollee in 5.2 percent of 
reported cases (i.e., the GAO reports that recoveries were made in 500 
cases out of 9,600 complaints about benefit denials received by the 
DOL from enrollees in self-funded plans). 

Systematic, standardized and richer data collection on claims denials 
and appeals is needed across market segments-–in both the commercially 
insured market and in self-funded group plans-—to provide transparency 
for consumers and meaningful information for policymakers.

Footnotes: 

[1] Private health insurance includes all forms of health insurance 
that are not funded by the government and may be purchased on an 
individual or group basis. 

[2] Pub. L. No. 111-148, 124 Stat. 119 (Mar. 23, 2010), as amended by 
the Health Care and Education Reconciliation Act of 2010, Pub. L. No. 
111-152, 124 Stat.1029 (Mar. 30, 2010). 

[3] Throughout this report, the term “insurer” refers to commercial, 
state-licensed issuers of health insurance coverage and entities such 
as health maintenance organizations (HMO). Insurers can offer coverage 
in the group market, individual market, or both. In this report, the 
term “insurer” does not include self-funded group health plans where 
instead of purchasing health insurance from an insurance company an 
employer sets aside its own funds to pay for at least some of its 
employees’ health care. 

[4] Throughout this report, we refer to denials of authorization for 
services not yet provided as “preauthorization denials” and denials of 
payment for services rendered as “claim denials.” 

[5] PPACA also directed that we submit our report to the Secretaries 
of HHS and DOL. Pub. L. No. 111-148, § 10107, 124 Stat. 911-2. 

[6] The data were reported by state-licensed health insurers offering 
coverage in the individual market. 

[7] This is the only quarter of data that HHS had collected as of 
December 2010. 

[8] The six states we selected to contact were California, 
Connecticut, Florida, Maryland, New York, and Ohio. 

[9] For example, through the course of our work, we found that Texas 
requires certain insurers to report on the number of requests for 
preauthorization of coverage for proposed services that insurers 
declined. 

[10] To conduct this review, we searched a number of reference 
databases, such as EconLit and Social SciSearch, for peer-reviewed, 
industry, or government studies published from January 2000 through 
July 2010. In addition, we checked the bibliographies of the studies 
and interviewed a number of experts regarding the research done on 
private health insurance denials to identify other relevant studies. 

[11] The insurance companies we contacted offered coverage in both the 
individual and group markets and, according to AHIP, were among the 10 
largest by enrollment, together accounting for nearly 26 million 
enrollees. 

[12] The data obtained from states on the incidence of coverage 
denials were not broken out by the types of medical services being 
denied. 

[13] State regulators established NAIC to help promote effective 
insurance regulation, to encourage uniformity in approaches to 
regulation, and to help coordinate states’ activities. Among other 
activities, NAIC collects data from state regulators on insurers, 
including complaints about insurer practices filed by consumers with 
states. We requested NAIC to provide us with data on the number of 
complaints reported by states that were related to coverage denials. 
The complaint data did not include information on the type of service 
for which coverage was denied. 

[14] Under PPACA, $30 million was appropriated to the Secretary of HHS 
for the award of federal grants to states to establish, expand, or 
provide support for offices of health insurance consumer assistance or 
health insurance ombudsmen programs. Pub. L. No. 111-148, § 1002, 124 
Stat. 138. To receive these grants, called Consumer Assistance Program 
grants, states must ensure that their programs assist consumers with 
such tasks as enrolling in health coverage and filing complaints and 
appeals. In the applications for the grants, HHS directed states to 
report on complaints and appeals. States varied in the data they 
included in their application and the time frames for those data. 

[15] Throughout this report, the term “group health plan” refers to 
employer-sponsored health plans, including both fully insured and self-
funded plans. 

[16] As of 2009, 85 percent of small employers, those with 3 to 199 
employees, that offered health benefits were fully insured while 88 
percent of large employers, those with 5,000 or more employees, 
offered self-funded plans. See The Kaiser Family Foundation and Health 
Research & Educational Trust, Employer Health Benefits: 2009 Annual 
Survey (2009). 

[17] Group health plans and health insurance issuers offering group 
coverage are prohibited from implementing eligibility rules based on 
health-status-related factors defined as health status, medical 
condition, claims experience, receipt of health care, medical history, 
genetic information, evidence of insurability, or disability. See, for 
example, 42 U.S.C. § 300gg-1 (2006). PPACA extends this prohibition to 
health insurance issuers offering coverage in the individual market 
for plan years beginning on or after January 1, 2014. Pub. L. No. 111-
148, § 1201(4), 124 Stat. 156. 

Health insurance issuers that offer coverage in the small group market 
in a state generally are required to accept every small employer that 
applies for health coverage in that state. In addition, issuers cannot 
deny an application for enrollment by individuals employed by such 
employers due to health-status-related factors if the individuals 
apply when they are first eligible. See 42 U.S.C. § 300gg-11 (2006). 
For plan years beginning on or after January 1, 2014, PPACA requires 
health insurance issuers offering group or individual coverage in a 
state to accept every employer and individual that applies for 
coverage in that state, subject to certain requirements. Pub. L. No. 
111-148, § 1201(4), 124 Stat. 156. 

[18] Health insurance issuers offering individual coverage are 
prohibited from denying coverage for individuals who (1) have had at 
least 18 months of prior creditable coverage with no break of more 
than 63 days; (2) have exhausted any available continuation of 
coverage; (3) are uninsured and are not eligible for other group 
coverage, Medicare, or Medicaid; and (4) did not lose group coverage 
because of the nonpayment of premiums or fraud. See 42 U.S.C. § 300gg-
41 (2006). As referenced above, PPACA requires health insurance 
issuers to guarantee coverage to all individuals seeking coverage in 
that state for plan years beginning on or after January 1, 2014, 
subject to certain requirements. 

[19] According to data from the Kaiser Family Foundation, as of 
January 2010, six states have guaranteed issue requirements that 
prohibit any insurer from denying coverage to an individual based on 
their current medical conditions or risk of poor health. Another seven 
states have guaranteed issue requirements that only apply to certain 
insurance plans or during limited times during the year.
As referenced above, in certain circumstances, federal law also 
protects consumers seeking individual coverage from application 
denials. For example, health insurance issuers cannot deny 
applications for eligible consumers who had prior group or other 
coverage. 

[20] See GAO, Health Insurance: Enrollment, Benefits, Funding, and 
Other Characteristics of State High-Risk Health Insurance Pools, 
[hyperlink, http://www.gao.gov/products/GAO-09-730R] (Washington, 
D.C.: July 22, 2009). 

[21] The temporary national HRP program will terminate in 2014. Pub. 
L. No. 111-148, § 1101, 124 Stat. 141. As referenced above, for plan 
years beginning on or after January 1, 2014, PPACA prohibits health 
insurance issuers offering individual coverage from implementing 
eligibility rules based on health status-related factors and requires 
health insurance issuers offering individual coverage to accept every 
individual in the state who applies for coverage, subject to certain 
requirements. In addition, PPACA prohibits group health plans and 
insurers offering group and individual coverage from excluding 
coverage for pre-existing health conditions. This prohibition is 
generally effective for plan years beginning on or after January 1, 
2014 for adults and plan years beginning on or after September 23, 
2010 for individuals under age 19. Pub. L. No. 111-148, § 1201(2), 
10103(e), (f), 124 Stat. 154, 895. 

[22] According to research completed by AHIP, as of January 2006, 44 
states and the District of Columbia operated external review programs. 
Such programs are generally available to consumers purchasing coverage 
from insurers regulated by states. 

[23] Under PPACA and implementing regulations, group health plans and 
health insurance issuers offering group or individual coverage, 
subject to certain exceptions, must comply with a state external 
review process that, at a minimum, includes consumer protections 
identified in the NAIC Uniform External Review Model Act. If a state 
external review process does not incorporate these consumer 
protections or a self-insured group health plan is not required to 
comply with the state external review process, then the health plan 
must follow a federal external review process. Pub. L. No. 111-148, §§ 
1001(5), 10101(g), 124 Stat. 137, 887; Interim Final Rules for Group 
Health Plans and Health Insurance Issuers Relating to Internal Claims 
and Appeals and External Review Processes under PPACA, 75 Fed. Reg. 
43,330 (July 23, 2010). 

[24] For example, with respect to those leaving group coverage and 
applying for coverage in the individual market, HIPAA prohibited 
health insurance issuers from denying coverage for individuals who (1) 
have had at least 18 months of prior creditable coverage with no break 
of more than 63 days; (2) have exhausted any available continuation of 
coverage; (3) are uninsured and are not eligible for other group 
coverage, Medicare, or Medicaid; and (4) did not lose group coverage 
because of the nonpayment of premiums or fraud. See 42 U.S.C. § 300gg-
41 (2006). 

[25] ERISA established certain federal requirements that apply when 
employers offer their employees, retirees, and dependents employee 
benefit plans that include health coverage, retirement plans such as 
pensions, and other benefits such as life insurance. See Pub. L. No. 
93-406, 88 Stat. 829 (1974). ERISA requirements generally apply 
regardless of the size of the business, although some requirements are 
streamlined for smaller employers. ERISA imposes certain reporting and 
disclosure requirements, fiduciary obligations, and requirements for 
claims-filing procedures. ERISA is enforced through DOL’s Employee 
Benefits Security Administration. PPACA expands upon ERISA’s 
requirements for claims-filing procedures by applying new standards 
for internal claims appeals and for external claims review processes, 
as referenced above. Pub. L. No. 111-148, §§ 1001(5), 10101(g), 137, 
887.

[28] The data indicated that two insurers had denial rates of 100 
percent and each of these insurers reported receiving one application 
in the 3-month reporting period. 

[29] In 2008, according to AHIP data, 84 percent of applications were 
medically underwritten and 16 percent were not medically underwritten. 
Just over 1 percent of applications were denied before going through 
medical underwriting, and those denials were unrelated to the applicant’
s health status.

study and other studies with information on application denial rates 
identified through our literature review.)

2006–2007: A Comprehensive Survey of Premiums, Availability, and 
Benefits (Washington, D.C.: 2007). 

[32] According to data from the Kaiser Family Foundation, as of 
January 2010, four states—-Michigan, Pennsylvania, Rhode Island, and 
Virginia—-and the District of Columbia have insurers of last resort, 
which are insurers that typically accept consumers with health 
conditions that prevent those consumers from obtaining coverage in the 
individual market. 

[33] The Ohio data included the number of electronically submitted 
claims paid and denied in the first and third quarters of calendar 
year 2009 and represented all insurers licensed in Ohio. The 
California data included the number of claims received and denied by 
six of the largest managed care insurers licensed in the state, each 
with enrollment in 2009 of over 400,000. We obtained these data from 
the Department of Managed Health Care’s Web site from June through 
September 2010 [hyperlink, http://www.wpso.dmhc.ca.gov/fe/search]. 

[34] The Maryland data were obtained from the Maryland Insurance 
Administration’s Report on Semi-Annual Claims Data Filing for Calendar 
Years 2005-2007 and represented data for calendar year 2007 from 41 
insurers licensed in the state. 

[35] The Connecticut data were obtained from the Connecticut Insurance 
Department’s Consumer Report Card on Health Insurance Carriers in 
Connecticut and represented data for calendar year 2009 from 21 
managed care insurers licensed in the state. 

[36] The data were reported to GAO by AMA and represented claims from 
February 1, 2010, through March 31, 2010. The data indicated the total 
number of claim lines-—charges for specific services included in the 
claim—-that were denied. AMA defines a denial as a claim line where 
the amount allowed and the amount billed were equal, but the amount 
paid was $0. Though not included in the claim denial rate, AMA also 
reported data indicating that 5 percent of claim lines were edited, 
that is, the claim lines were automatically reduced to a payment of $0 
by the insurer’s payment system. According to AMA officials, both 
claim-line denials and claim-line edits result in no payment for the 
service, and therefore are denials from the perspective of the 
provider. The data on claim lines denied and edited were used as the 
basis for rates reported in AMA’s 2010 National Health Insurer Report 
Card. See citations to the 2010 report card and previous AMA report 
cards as well as other studies related to coverage denials in appendix 
II. 

[37] Providers can submit paper or electronic claims. According to 
Ohio and AMA officials, electronic claims represented roughly 70 to 80 
percent of their total claims activity. 

[38] California officials told us they currently require plans to 
report on their full “inventory” of denials but the state is revising 
its claim denial reporting instructions to clarify the denials that 
should be included and excluded from the numbers reported. 

[39] According to officials, the AMA claim data included data for 
insured products offered by the companies represented and self-insured 
products administered by the companies. 

[40] The calendar year 2007 data were obtained from the Maryland 
Insurance Administration’s Report on Semi-Annual Claims Data Filing 
for Calendar Years 2005-2007. 

[41] Maryland reports the total claim denial rate, as well as a denial 
rate for “clean claims”—those health care claims submitted by a health 
care provider on one of two widely used industry standard billing 
forms and that also include all of the essential information needed by 
a plan for processing—in their Semi-Annual Claims Data Filing Reports. 

[42] The data were obtained from The Maryland Insurance 
Administration’s 2007 Report on the Health Care Appeals & Grievances 
Law. 

[43] The data were obtained from the Maryland Insurance 
Administration’s Report on Semi-Annual Claims Data Filing for Calendar 
Years 2005-2007. 

[44] The data on the reasons for claim denials reflect the reasons 
assigned by the insurer that denied the claim. According to AMA 
officials, there is no requirement that insurers assign the most 
specific reason for the claim denial, and they sometimes assign more 
general reasons. For example, although a denial may have occurred 
because the insurer determined a service was not medically necessary, 
the insurer may document that the claim was denied because the service 
was not covered, which could be for reasons other than that the 
service was not medically necessary. 

[45] Reversals of coverage denials were limited to denials for which 
an appeal was initiated. The data we reviewed did not allow for a 
systematic calculation of an “appeal rate”-—the number of coverage 
denials for which an appeal was initiated—-for several reasons, 
including different data sources or data years for denials and appeals 
data. Data from Ohio did provide limited information; specifically, 
for the first quarter of calendar year 2010, Ohio data indicated that 
0.5 percent of claim denials were internally appealed.

(Washington, D.C.: 2006). 

[47] C. R. Gresenz and D. M. Studdert, “External Review of Coverage 
Denials by Managed Care Organizations in California” (RAND Institute 
for Civil Justice, Santa Monica, Calif.: 2005). See appendix II for 
the list of studies that included external appeal data by the reason 
for the denial being appealed and the type of service being denied. 

[48] Data were reported to GAO by the Florida Agency for Health Care 
Administration. Maryland’s data, obtained from the Maryland Insurance 
Administration’s 2009 Report on the Health Care Appeals & Grievances 
Law, also included some information on external appeals by the type of 
service being denied. 

[49] In October 2010, HHS awarded nearly $30 million in Consumer 
Assistance Program grants to 35 states and the District of Columbia. 
States receiving the grants are required to begin reporting data 6 
months after the award notice on the number of inquiries filed with 
the state about health coverage, the reasons for the inquiries, and 
the outcomes of the inquiries. 

[50] Because we did not survey all states to determine whether they 
collect data on the incidence of application or coverage denials, there 
may be other states that collect such data that were not known to 
experts or discussed in the literature. For example, through the course 
of our work, we found that Texas requires certain insurers to report on 
the number of requests for verification of coverage for proposed 
services that insurers declined.

[52] We searched the reference databases for the terms "denial" or 
"refusal" and "health plan," "insurer," "carrier," or "issuer" with all 
of the following combinations of terms: (1) "application" or 
"enrollment;" (2) "coverage," "claim," or "preauthorization;" and (3) 
"complaint," "appeal," or "dispute" and "coverage," "claim," "service," 
or "preauthorization."
