Government Organization, Efficiency and Financial Management, 
Committee on Oversight and Government Reform, House of Representatives. 

Why GAO Did This Study: 

GAO has designated Medicare as a high-risk program because of its 
size, complexity, and susceptibility to improper payments. In 2010, 
Medicare covered 47 million elderly and disabled beneficiaries and had 
estimated outlays of $516 billion. The Centers for Medicare & Medicaid 
Services (CMS) is the agency in the Department of Health and Human 
Services (HHS) responsible for administering the Medicare program and 
leading efforts to reduce Medicare improper payments. 

This testimony focuses on estimated improper payments in the Medicare 
program for fiscal year 2010 and the status of CMS’s efforts to 
implement key strategies to help reduce improper payments. This 
testimony is primarily based on previous GAO reporting related to 
governmentwide improper payments, Medicare high-risk challenges and 
program integrity efforts, and CMS’s information technology systems 
intended to identify improper payments. GAO supplemented that prior 
work with additional information on the nature and extent of Medicare 
improper payments reported by HHS in its fiscal year 2010 agency 
financial report. GAO also received updated information from CMS in 
February 2011 and, in select cases, as of July 2011, on its actions 
related to relevant laws, regulations, guidance, and open 
recommendations pertaining to key remediation strategies. 

What GAO Found: 

For fiscal year 2010, HHS reported an estimate of almost $48 billion 
in Medicare improper payments, representing about 38 percent of the 
total $125.4 billion estimate for the federal government. However, 
this Medicare improper payment estimate is incomplete because HHS has 
yet to develop a comprehensive estimate for the Medicare prescription 
drug benefit. The improper payment estimate includes both overpayments 
and underpayments. Causes cited include inadequate documentation, 
medically unnecessary services, coding errors, and payment calculation 
errors. It is important to recognize that the $48 billion is not an 
estimate of fraud in Medicare. Because the improper payment estimation 
process is not designed to detect or measure the amount of fraud that 
may exist, there may be fraud that is not reflected in HHS’s reported 
estimate. 

CMS faces challenges in designing and implementing internal controls 
to effectively prevent or detect and recoup improper payments. In 
2010, CMS established the Center for Program Integrity to serve as its 
focal point for all national Medicare program integrity issues. Based 
on past work, GAO identified five key strategies to help reduce fraud, 
waste, and abuse and improper payments in Medicare, which CMS has 
reported initiating actions to address. GAO has made recommendations 
to strengthen CMS’s implementation of these strategies, some of which 
the agency has not implemented. 

Strengthen provider enrollment standards and procedures. Strong 
standards and procedures can help reduce the risk of enrolling 
providers intent on defrauding the program. CMS has taken action to 
implement provisions of the Patient Protection and Affordable Care Act 
by screening providers by levels of risk and providing more stringent 
review of high-risk providers, but has yet to implement certain GAO 
recommendations in this area. 

Improve prepayment reviews. Prepayment reviews of claims help ensure 
that Medicare pays correctly the first time. According to CMS, as of 
July 1, 2011, CMS has begun applying predictive modeling analysis to 
claims and plans to expand Medicare prepayment controls. CMS has not 
implemented GAO’s recommendation to improve prepayment reviews. 

Focus postpayment reviews on vulnerable areas. Postpayment reviews are 
critical to identifying payment errors and recouping overpayments. In 
March 2009, CMS began instituting a national recovery audit contractor 
(RAC) program to help the agency supplement its postpayment reviews. 
CMS has also developed information technology to help it better 
identify claims paid in error, but GAO recently reported that the 
systems are not being used to the extent originally planned and made 
several recommendations to address the issues. 

Improve oversight of contractors. CMS has taken action to improve 
oversight of prescription drug plan sponsors’ fraud and abuse 
programs, which addresses GAO’s recommendation, but is still 
developing specific performance statistics. 

Develop a robust process to address identified vulnerabilities. Having 
mechanisms in place to resolve vulnerabilities that lead to improper 
payments is critical. While CMS has begun actions in this area, it has 
not developed a robust corrective action process for vulnerabilities 
identified by Medicare RACs as GAO recommended.

Chairman Platts, Ranking Member Towns, and Members of the Subcommittee: 

Thank you for the opportunity to be here today to discuss improper 
payments in the Medicare program, as well as the Centers for Medicare 
& Medicaid Services' (CMS) efforts to remediate them. In 2010, 
Medicare covered 47 million elderly and disabled beneficiaries and had 
estimated outlays of $516 billion, making it one of the largest 
federal programs. Medicare consists of four parts: A, B, C, and D. 
Medicare Parts A and B are known as Medicare fee-for-service. Part A 
covers hospital and other inpatient stays. Medicare Part B covers 
hospital outpatient, physician, and other services. Part C is Medicare 
Advantage, under which beneficiaries receive benefits through private 
health plans. Part D is the Medicare outpatient prescription drug 
benefit. CMS is the agency in the Department of Health and Human 
Services (HHS) responsible for administering the Medicare program and 
leading efforts to reduce Medicare improper payments. 

GAO has designated Medicare as a high-risk program because of its 
size, complexity, and susceptibility to improper payments.[Footnote 1] 
As defined by the Improper Payments Elimination and Recovery Act of 
2010 (IPERA), an improper payment is any payment that should not have 
been made or that was made in an incorrect amount (including 
overpayments and underpayments) under statutory, contractual, 
administrative, or other legally applicable requirements.[Footnote 2] 
For fiscal year 2010, federal agencies reported an estimated $125.4 
billion in improper payments, of which Medicare accounts for nearly 
$48 billion--the highest estimated amount of improper payments in a 
single program. The Medicare improper payment estimates do not reflect 
all of the program's risk because HHS did not report a total improper 
payment estimated amount for its Medicare prescription drug benefit 
program (Part D). Despite progress made by CMS, reducing improper 
payments in the program is a continuing challenge for CMS due to the 
size and scope of Medicare. 

Fiscal year 2010 marked the 7th year of implementation of the Improper 
Payments Information Act of 2002 (IPIA).[Footnote 3] IPIA requires 
executive branch agencies to annually review all programs and 
activities to identify those that are susceptible to significant 
improper payments, estimate the annual amount of improper payments for 
such programs and activities, and report these estimates along with 
actions taken to reduce improper payments for programs with estimates 
that exceed $10 million. IPERA, enacted July 22, 2010, amended IPIA by 
expanding the previous requirements for identifying, estimating, and 
reporting on programs and activities susceptible to significant 
improper payments and expanding requirements for recovering 
overpayments across a broad range of federal programs.[Footnote 4] 
IPERA provisions generally became effective in fiscal year 2011. The 
Office of Management and Budget (OMB) has since issued updated 
guidance for federal agencies on reporting, reducing, and recovering 
improper payments.[Footnote 5] In addition, the Patient Protection and 
Affordable Care Act (PPACA),[Footnote 6] as amended by the Health Care 
and Education Reconciliation Act of 2010,[Footnote 7] contains 
provisions designed to help reduce improper payments in the Medicare 
program. See appendix I for additional information about recent 
congressional and executive branch actions related to Medicare 
improper payments. 

Today, my testimony will focus on two areas: 

* HHS reported estimated improper payments in the Medicare program for 
fiscal year 2010, and: 

* the status of CMS's efforts to implement key strategies to help 
remediate improper payments in the Medicare program. 

My statement today is based primarily on previous GAO reporting 
related to governmentwide improper payments, Medicare high-risk 
challenges and program integrity efforts, and CMS's information 
technology systems intended to help identify improper payments. We 
supplemented that prior work with additional information on the nature 
and extent of Medicare improper payments reported by HHS in its fiscal 
year 2010 agency financial report (AFR). We also received updated 
information from CMS in February 2011 and, in select cases, as of July 
2011, on its actions related to relevant laws, regulations, guidance, 
and open recommendations pertaining to the key remediation strategies 
discussed later in this statement. A list of related GAO products is 
included at the end of this statement. Our prior work was conducted 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. 

Improper Payments in the Medicare Program: 

HHS annually reports on improper payments in its AFR. For fiscal year 
2010, HHS reported improper payment estimates for several programs, 
including Medicare. Collectively, HHS reported an estimate of almost 
$48 billion in improper payments in Medicare.[Footnote 8] The $48 
billion in estimated improper payments reported for fiscal year 2010 
is attributable to Medicare fee-for-service and Medicare Advantage. 
[Footnote 9] As shown in figure 1, the Medicare program represents 
about 38 percent of the $125.4 billion improper payment estimated 
amount reported by 20 federal agencies covering 70 programs. Further, 
Medicare's estimated improper payment amount is the highest among all 
federal programs that reported an estimated amount. 

Figure 1: Fiscal Year 2010 Estimated Improper Payment Reported Amounts 
for Federal Programs: 

[Refer to PDF for image: pie-chart] 

Medicare Fee-for-Service: 27% ($34.3 billion); 
Medicare Advantage: 11% ($13.6 billion); 
Other federal programs: 62% ($77.5 billion).

[End of figure] 

HHS's estimated amount of improper payments for Medicare is incomplete 
because it has yet to report a comprehensive improper payment estimate 
for the Medicare prescription drug benefit program, which had reported 
outlays of about $59 billion in fiscal year 2010. However, HHS has 
taken some steps to develop a comprehensive improper payment error 
rate.[Footnote 10] Specifically, for fiscal year 2010, HHS calculated 
error rates for the four components of the Medicare prescription drug 
benefit program, with the estimates ranging from $45 million to $5.4 
billion for each component. However, HHS reported that the four 
estimates overlap and consequently cannot be totaled. HHS reported 
that it expects to report a comprehensive estimate for the 
prescription drug benefit program in fiscal year 2011. 

It is important to recognize that the $48 billion in estimated 
improper payments reported by HHS in fiscal year 2010 is not an 
estimate of fraud in Medicare.[Footnote 11] Reported improper payment 
estimates include many types of overpayments, underpayments, and 
payments that were not adequately documented. In addition, because the 
improper payment estimation process is not designed to detect or 
measure the amount of fraud in Medicare, there may be fraud that 
exists in the Medicare program that is not included in the reported 
improper payment estimate. 

In addition to inadequate documentation, HHS cited a number of other 
causes for the estimated $48 billion in reported improper payments, 
including the provision of services that were found not to be 
medically necessary, coding errors, incorrect interpretation of data, 
and payment calculation errors. HHS reported that its analysis showed 
most Medicare fee-for-service improper payments were for medically 
unnecessary durable medical equipment and inpatient hospital services. 
For Medicare Advantage, HHS reported that the majority of the improper 
payment estimate resulted from insufficient documentation to support 
the diagnoses submitted by private health plans for payment. 

CMS's methodology for estimating improper payments has evolved. 
Beginning in 1996, HHS's Office of Inspector General (OIG) estimated 
improper payments in the Medicare fee-for-service program as part of 
its annual financial statement audit. In fiscal year 2003, CMS assumed 
responsibility for estimating Medicare fee-for-service improper 
payments and modified the methodology to improve error detection and 
provide more detailed information on the errors. During fiscal year 
2009, HHS revised its methodology for calculating the Medicare fee-for-
service improper payment error rate based on HHS OIG audit reports and 
input from CMS advisory medical staff. According to HHS, the revised 
methodology is more stringent. Using this revised methodology for a 
limited number of claims reviewed in fiscal year 2009, HHS reported 
estimated Medicare fee-for-service improper payments of $24.1 billion 
in its fiscal year 2009 AFR, representing an error rate of 7.8 
percent. However, HHS subsequently restated the fiscal year 2009 
improper payment estimate for Medicare fee-for-service by applying the 
results of the revised methodology to the entire year and reported a 
revised estimate of $35.4 billion and an error rate of 12.4 percent. 

CMS set key performance measures to reduce improper payments for 
Medicare fee-for-service and Medicare Advantage. For fiscal year 2010, 
HHS reported error rates of 10.5 percent and 14.1 percent for Medicare 
fee-for-service and Medicare Advantage, respectively. HHS reported 
that it met its improper payment error rate target for Medicare 
Advantage in fiscal year 2010 by achieving a 14.1 percent error rate, 
which was better than its goal of 14.3 percent. However, CMS was not 
able to demonstrate sustained progress in reducing its Medicare fee-
for-service improper payment rate. As discussed previously, HHS 
reported that it made changes to improve the estimation methodology, 
which meant that previous estimates were not comparable to those HHS 
made in fiscal year 2010. For fiscal year 2012, CMS reported that it 
set improper payment reduction targets as part of the strategic plan 
prepared under the Government Performance and Results Act of 1993. 
[Footnote 12] The 2012 target error rates are 6.2 percent for Medicare 
fee-for-service and 13.2 percent for Medicare Advantage. 

Further, in response to Executive Order 13520,[Footnote 13] HHS 
designated the Assistant Secretary for Financial Resources and Deputy 
Administrator for Program Integrity at CMS as the accountable 
officials responsible for efforts to reduce improper payments and 
establish improper payment reduction targets for Medicare fee-for-
service and Medicare Advantage as shown in figure 2.

In 2010, CMS created the Center for Program Integrity (CPI) to serve 
as its focal point for all national Medicare program integrity issues. 
CPI is responsible for addressing program vulnerabilities leading to 
improper payments, including collaborating with other CMS components 
to develop and implement a comprehensive strategic plan, objectives, 
and measures to carry out the agency's program integrity mission and 
goals. According to CMS documentation describing the program, CPI was 
designed to promote Medicare integrity through the following 
activities: 

* conducting provider and contractor audits and policy reviews; 

* identifying and monitoring program vulnerabilities; 

* providing support and assistance to states; 

* collaborating on the development and advancement of new legislative 
initiatives and improvements to deter, reduce, and eliminate fraud, 
waste, and abuse; 

* overseeing all CMS interactions and collaboration with key 
stakeholders related to program integrity (e.g., the Department of 
Justice, HHS OIG, and state law enforcement agencies) for the purposes 
of detecting, deterring, monitoring, and combating fraud and abuse; 
and: 

* taking action against those who commit or participate in fraudulent 
or other unlawful activities. 

Status of CMS's Efforts to Implement Key Strategies to Help Remediate 
Improper Payments: 

CMS has begun a number of initiatives related to the five strategies 
identified in our previous reporting that are key to reducing Medicare 
improper payments. However, CMS still faces significant challenges in 
designing and implementing internal controls to effectively prevent or 
detect and recoup improper payments and to prevent fraud, waste, and 
abuse. In March 2011, we testified that effective implementation of 
GAO recommendations, provisions in recently enacted laws, and recent 
guidance related to five key strategies could help remediate fraud, 
waste, abuse, and improper payments in the Medicare program.[Footnote 
14] Figure 3 provides an overview of those key strategies.

Program:

We testified in March 2011 that PPACA had a number of provisions that, 
if effectively addressed, could aid CMS in its efforts to minimize 
improper payments.[Footnote 15] Specifically, PPACA included 
provisions related to strengthening provider enrollment and improving 
contractor oversight. CMS had issued final rules implementing some of 
these provisions. In addition, in June 2011, we reported on challenges 
CMS has faced in implementing information technology systems to help 
it identify potentially fraudulent or abusive claims that had been 
paid.[Footnote 16] 

The following sections provide an overview of CMS reported actions 
related to each of the five strategies we identified in our prior 
reporting as key to helping reduce Medicare improper payments. GAO has 
made recommendations to strengthen CMS's actions to address these 
strategies, some of which have not been implemented. 

Strengthening provider enrollment standards and procedures. 
As discussed in our March 2011 testimony,[Footnote 17] strengthening 
the standards and procedures for provider enrollment could help reduce 
the risk of enrolling providers intent on defrauding or abusing the 
program. CMS has previously identified two types of providers whose 
services and items are especially vulnerable to improper payments--
home health agencies (HHA) and suppliers of durable medical equipment, 
prosthetics, orthotics, and supplies (DMEPOS). In our 2009 report on 
HHAs, we found problems with the enrollment procedures--for example, 
CMS's contractors were not requiring HHAs to resubmit enrollment 
information (including information about key officials, operating 
capital, and practice location) for reverification every 5 years as 
required by CMS.[Footnote 18] CMS implemented one of the 
recommendations from that report but did not implement a 
recommendation to revoke billing privileges from HHAs engaged in a 
pattern of improper billing practices. In a 2005 report on DMEPOS 
suppliers, we found that CMS had not taken sufficient steps to prevent 
entities intent on defrauding Medicare from enrolling, and we reported 
that more effective screening and stronger enrollment standards were 
needed to ensure that new suppliers were legitimate 
businesses.[Footnote 19] Partly in response to our recommendation to 
improve the provider enrollment process, CMS took steps to implement 
new supplier quality standards as part of an accreditation rule issued 
in August 2006 and proposed new supplier enrollment standards in 
January 2008. It proposed that suppliers would be required to meet 
these new accreditation standards in 2009. However, the new supplier 
enrollment standards were not finalized until August 2010. 

Several requirements in PPACA focus on strengthening provider 
enrollment procedures, which could help prevent Medicare from making 
improper payments and address some of our previous concerns and 
recommendations. For example, PPACA requires the Secretary of HHS, in 
consultation with the HHS OIG, to establish procedures for screening 
providers enrolling in Medicare, including assessing the risk levels 
of fraud, waste, and abuse by categories of providers. At a minimum, 
PPACA requires all providers to be subject to licensure checks, which 
may include checks across state lines. Further, PPACA provides for 
enhanced oversight of new providers for specific periods of time and 
of initial claims of DMEPOS suppliers. On February 2, 2011, CMS and 
the HHS OIG published a final rule to implement these new screening 
procedures.[Footnote 20] In addition, PPACA imposes specific 
requirements for providers to disclose any current or previous 
affiliation with a provider that has uncollected debt; has been or is 
subject to a payment suspension under a federal health care program; 
has been excluded from participation under Medicare, Medicaid, or the 
Children's Health Insurance Program or has had its billing privileges 
denied or revoked. The law allows CMS to deny enrollment to any such 
provider whose previous affiliations pose an undue risk. In February 
2011, CMS officials told us that they were drafting a proposed rule to 
implement this authority. Further, providers that order home health 
services must have a face-to-face encounter with the beneficiary 
before the services can be ordered. CMS issued a final rule regarding 
this requirement in November 2010. To reduce spending for durable 
medical equipment and related supplies, the Medicare Prescription 
Drug, Improvement, and Modernization Act of 2003 (MMA) required that 
CMS phase in, with several rounds of bidding, a large scale 
competitive bidding program for certain DMEPOS.[Footnote 21] CMS began 
to implement a Medicare competitive bidding program for durable 
medical equipment and supplies with prices that took effect in January 
2011 from the first round of bidding. This program has the potential 
to help reduce fraud, waste, and abuse because it requires CMS to 
select DMEPOS suppliers based in part on new scrutiny of their 
financial documents and other application materials, among other 
things. PPACA required CMS to expedite implementation of the 
competitive bidding program for durable medical equipment, expanding 
the number of areas to be included in the second round of bidding from 
70 to 91 by the end of 2011. CMS told us that it was working on round 
2 of the competitive bidding program, which is anticipated to be 
operational in summer 2013. 

Improving prepayment review of claims. 
Our prior reporting on Medicare found that prepayment reviews of 
claims are essential to help ensure that Medicare pays correctly the 
first time. Conducting these reviews is challenging due to the volume 
of claims. Overall, less than 1 percent of Medicare's claims are 
subject to a medical record review by trained contractor personnel. 
Therefore, having robust automated payment controls--called edits--in 
place to deny inappropriate claims or flag them for further review is 
critical. However, in our 2007 report, we identified weaknesses in 
these prepayment controls.[Footnote 22] For example, we found that 
contractors responsible for reviewing DMEPOS claims did not have 
automated prepayment controls in place to identify questionable 
claims, such as those associated with atypically rapid increases in 
billing or for items unlikely to be prescribed in the normal course of 
medical care. Since then, CMS has added computer edits to flag claims 
for services unlikely to be provided in the normal course of medical 
care, but has not implemented our recommendation to have edits in 
place based on thresholds for unexplained increases in billing. 

If implemented, several recent legislative requirements and 
administrative directives could help CMS with its prepayment review to 
prevent improper payments. First, the Small Business Jobs Act of 2010 
requires CMS to use predictive modeling and other analytic techniques--
known as predictive analytic technologies--both to identify and to 
prevent improper payments under the Medicare fee-for-service program. 
[Footnote 23] These predictive analytic technologies will be used to 
analyze and identify Medicare provider networks, billing patterns, and 
beneficiary utilization patterns and detect those that represent a 
high risk of fraudulent activity. Through such analysis, unusual or 
suspicious patterns or abnormalities could be identified that could be 
used to prioritize additional review of suspicious transactions before 
payment is made. CMS published a solicitation in December 2010 for 
these technologies and a case management system to track findings. The 
legislation provides that the solicitation require contractors that 
are selected to begin using these technologies on July 1, 2011, in the 
10 states identified by CMS as having the highest risk of fraud, 
waste, or abuse in Medicare fee-for-service payments. After the 
initial year, based on the results of the predictive analytic 
technologies, CMS reported that it plans to expand their use to other 
states beyond the 10 states identified as having the highest risk for 
fraud, waste, and abuse. According to CMS, as of July 1, 2011, initial 
predictive modeling has been used on claims prior to payment to 
identify their level of risk for being improper and to focus 
investigative efforts. 

Second, a June 2010 presidential memorandum directed agencies to check 
certain databases--known as the "Do Not Pay List"--before making 
payments, to ensure that payments do not go to individuals who were 
deceased or excluded from receiving federal payments or to entities 
that had been excluded from receiving federal payments. As of July 
2011, this governmentwide database was still under development. 
However, CMS officials stated that, in response to the presidential 
memorandum, the agency reviewed selected databases that it and its 
Medicare contractors were using to determine payment eligibility for 
providers and took action to ensure that the agency's method of 
ensuring payment eligibility was consistent with the intent of the "Do 
Not Pay List." 

Focusing postpayment claims review on most vulnerable areas. 
We previously reported that postpayment reviews are critical to 
identifying payment errors to recoup overpayments in Medicare. CMS's 
claims administration contractors conduct limited postpayment reviews. 
Therefore, it is important that they target their postpayment review 
resources on providers with a demonstrated high risk of improper 
payments. Further, we previously reported that CMS could strengthen 
postpayment home health claims review by focusing postpayment claims 
review on the most vulnerable areas and increasing the amount of 
postpayment review by using recovery audit contractors (RAC) for the 
Medicare program. CMS has not acted to implement our recommendation 
about focusing postpayment home health claims review based on high 
rates of improper billing identified through prepayment reviews. CMS 
has had efforts focusing on postpayment review of claims, most 
recently its national RAC program, begun in March 2009, after 
completion of a 3-year demonstration program in 2008.[Footnote 24] The 
national program was designed to help the agency supplement the 
postpayment reviews conducted by contractors other than RACs. The RACs 
review fee-for-service claims after payment, but because RACs are paid 
a contingent fee based on the dollar value of the improper payments 
identified, they have focused on claims from inpatient hospital stays, 
which are generally more costly services. PPACA expanded Medicare's 
RAC program to Medicare Advantage and the prescription drug benefit 
program. CMS published a request for comments on the development of 
RACs for those programs in December 2010. CMS awarded a Medicare 
prescription drug benefit RAC task order for a 1-year base period that 
began January 2011 and included 4 option years. 

In June 2011, we reported that CMS has also developed information 
technology to help it better identify claims paid in error, but the 
systems are not being used to the extent originally planned, and CMS 
has not measured whether they have helped in reducing payment errors. 
[Footnote 25] To integrate claims information and improve its ability 
to identify fraud, waste, and abuse, CMS initiated two information 
technology system programs in 2006: the Integrated Data Repository 
(IDR)[Footnote 26] and One Program Integrity (One PI) to centralize 
and make more accessible the data needed to conduct these analyses. 
The IDR was intended to provide a central source of data related to 
Medicare and Medicaid claims, and the One PI system is a web-based 
portal and suite of analytical software tools to be used to extract 
data from IDR and enable complex analyses of these data. 

As we reported in June 2011, although CMS has developed and 
implemented IDR and One PI for use by its program integrity analysts, 
IDR did not include all the data the agency planned to have 
incorporated by the end of 2010.[Footnote 27] For example, IDR 
includes most types of Medicare claims data, but did not include data 
from other CMS systems that are needed to help analysts identify 
improper payments. According to IDR program officials, these data were 
not incorporated into IDR because funding for the development of the 
software and acquisition of the hardware needed to meet this 
requirement was not approved until the summer of 2010. Since then, IDR 
program officials have developed project plans and identified users' 
requirements, and plan to incorporate these additional data by 
November 2011. 

In addition, CMS has developed and deployed One PI, but the system has 
been used by a limited number of analysts--less than 7 percent of the 
intended user community--and did not yet provide as many tools as 
planned. According to agency officials, plans to train and deploy the 
system to a broad community of users were disrupted when resources 
dedicated to these activities were redirected to address a need to 
improve the user training program. Further, as of June 2011, plans and 
schedules for completing the remaining work had not been finalized, 
and CMS had not identified risks and obstacles to project schedules 
that may affect its ability to ensure broad use and full 
implementation of the systems. Consequently, the agency may miss an 
opportunity to effectively use these information technology solutions 
to enhance its ability to detect fraud, waste, and abuse in the 
Medicare program. In our June 2011 report, we made seven 
recommendations to help ensure that the development and implementation 
of IDR and One PI help CMS meet its program integrity goals and 
objectives.[Footnote 28] CMS concurred with GAO's recommendations and 
agreed to act upon them. 

Improving oversight of contractors. 
As called for in our Standards for Internal Control in the Federal 
Government,[Footnote 29] monitoring the activities used by an 
organization to address improper payments should be performed 
continually and should be ingrained in the entity's operations. Over 
the years, we have found areas where CMS's oversight of contractor 
activities that provide services to Medicare beneficiaries had been 
insufficient to ensure that required program control activities were 
conducted and working well. For example, all Part D drug-plan sponsors 
are required to have programs to prevent, detect, and correct fraud, 
waste, and abuse--also referred to as fraud and abuse programs. CMS is 
responsible for ensuring that sponsors are in compliance with this 
requirement. However, in 2008 we found that CMS's oversight of these 
programs was limited.[Footnote 30] We recommended that CMS conduct 
timely audits of sponsors' fraud and abuse programs. CMS agreed with 
this recommendation. In March 2010, we reported that CMS had completed 
desk audits of selected sponsors' programs and was beginning to 
implement an expanded oversight strategy, including on-site audits to 
assess the effectiveness of these programs more thoroughly.[Footnote 
31] In November 2010, CMS officials reported that the agency had 
conducted on-site audits of 33 of the 290 sponsors in 2010 covering 62 
percent of the enrolled beneficiaries in 2010, which addresses our 
recommendation. As a result of the on-site audits, CMS had taken 
formal enforcement actions against several sponsors. In addition, CMS 
published a final rule in April 2010 to increase its oversight efforts 
and ensure that sponsors have effective programs in place.[Footnote 
32] PPACA included provisions for CMS to evaluate contractors 
receiving Medicare Integrity Program and Medicaid Integrity Program 
funding every 3 years. In addition, PPACA requires these contractors 
to provide performance statistics to HHS and its OIG upon request. In 
February 2011, CMS officials told us that they were taking action to 
implement these requirements for Medicare. At that time, officials 
told us that CMS was tracking performance statistics and adding to and 
refining these statistics and was also developing the specific 
performance statistics for its Part D integrity contractors and 
expected to finalize these statistics this year. 

Developing a robust process for addressing identified vulnerabilities. 
Having mechanisms in place to resolve vulnerabilities that lead to 
improper payments is key to effective program management. But our work 
has shown that CMS has not developed a robust process to specifically 
address identified vulnerabilities that lead to improper payments in 
Medicare. We have reported that an agency should have policies and 
procedures to ensure that (1) the findings of all audits and reviews 
are promptly evaluated, (2) decisions are made about the appropriate 
response to these findings, and (3) actions are taken to correct or 
resolve the issues promptly.[Footnote 33] We have also stressed the 
importance of holding individuals accountable for achieving agency 
objectives. However, as we reported in March 2010, CMS had not 
established an adequate process during its recovery audit contracting 
demonstration or in planning for the subsequent recovery audit 
national program to ensure prompt resolution of identified improper 
payment vulnerabilities in Medicare.[Footnote 34] During the 
demonstration, CMS did not assign responsibility to agency officials 
or contractors for taking corrective action. According to CMS 
officials, the agency took corrective action only for vulnerabilities 
with national implications, and let the contractors that processed and 
paid claims decide whether to take action for vulnerabilities that 
might occur only in certain geographic areas. Additionally, we 
reported that during the demonstration CMS did not specify in a plan 
what type of corrective action was required or establish a time frame 
for corrective action. We also found that the lack of documented 
responsibility assignments impeded CMS's efforts to promptly resolve 
the vulnerabilities identified during the demonstration. 

For the national Medicare RAC program, although CMS established a 
corrective action team to compile, review, and categorize identified 
vulnerabilities and discuss corrective action recommendations, the 
corrective action process was still incomplete. CMS appointed the 
Director of the Office of Financial Management to be responsible for 
the day-to-day operations of the program, and the CMS Administrator to 
be responsible for vulnerabilities that span agency components. 
However, the corrective action process did not include any steps to 
either assess the effectiveness of the corrective actions taken or 
adjust them as necessary based on the results of the assessments. 
Further, the agency had not developed time frames for implementing 
corrective actions. Because of these weaknesses, we recommended that 
CMS develop and implement a corrective action process that includes 
policies and procedures to ensure that the agency promptly (1) 
evaluates findings of RAC audits, (2) decides on the appropriate 
response and a time frame for taking action based on established 
criteria, and (3) acts to correct the vulnerabilities 
identified.[Footnote 35] CMS concurred with this recommendation. 
Agency officials said they intended to review vulnerabilities on a 
case-by-case basis and were considering assigning them to risk 
categories to help prioritize their actions. In February 2011, CMS 
reported that the agency was still working to address the 
vulnerabilities identified during the demonstration program. Specific 
to corrective actions, CMS officials told us that its contractors were 
required to consider and evaluate vulnerabilities identified by 
various entities, including the RACs. However, as of March 2011, CMS 
had not yet implemented this recommendation. We will continue to 
follow up with CMS on its progress in this area. 

Concluding Observations: 

With the amount of estimated improper payments and the unknown amounts 
of potential fraud, waste, and abuse in the Medicare program, it is 
critical for CMS to act quickly and decisively to reduce them. As it 
implements PPACA provisions concerning Medicare, CMS has an 
opportunity to use new tools to help address fraud, waste, abuse, and 
improper payments in the program. CMS has taken a number of actions 
related to rule making and issuing guidance to implement recent 
legislative and regulatory provisions, but because many efforts are in 
process, it is too early to gauge their effectiveness. These 
requirements will be critical in helping ensure integrity in Medicare 
operations, as will additional evaluation and oversight to determine 
whether they are implemented as intended and have the desired effect 
on ensuring that payments are made for intended and proper purposes. 
Notably, we are beginning new work to assess CMS's efforts to 
strengthen the standards and procedures for Medicare provider 
enrollment to reduce the risk of enrolling providers that are intent 
on defrauding or abusing the program. We are also examining the 
effectiveness of different types of prepayment edits in Medicare 
systems and of CMS's oversight of its contractors in implementing 
those edits to help ensure that Medicare pays claims correctly the 
first time. The level of importance CMS places on effectively 
implementing our recommendations and the requirements established by 
recent laws and guidance will be a key factor in reducing improper 
payments and potential fraud, waste, and abuse in the Medicare program 
and ensuring that federal funds are used efficiently and for their 
intended purposes. In this regard, we plan to continue monitoring 
these issues. 

Chairman Platts, Ranking Member Towns, this completes my prepared 
statement. I would be happy to respond to any questions you or other 
members of the subcommittee may have at this time.

Appendix I: Recent Key Legislative and Executive Branch Efforts: 

Over the past couple of years, Congress and the executive branch have 
taken a number of actions intended to heighten the attention given to 
the issue of improper payments and to promote corrective actions. The 
Centers for Medicare & Medicaid Services' (CMS) efforts to identify 
and remediate Medicare improper payments will be affected by these new 
initiatives. Table 1 summarizes the recent legislative and executive 
branch efforts intended to improve oversight and accountability over 
improper payments governmentwide, as well as key actions specific to 
Medicare.

[End of table] 

In November 2009, Executive Order 13520, Reducing Improper Payments, 
was intended to focus on increasing transparency and accountability 
for reducing improper payments and creating incentives for reducing 
improper payments.[Footnote 36] Under the Executive Order, the Office 
of Management and Budget (OMB) designated 14 programs as high-priority 
programs to focus attention on the programs that significantly 
contribute to the federal government's improper payments. Medicare fee-
for-service, Medicare Advantage, and Medicare prescription drug 
programs have been designated as high-priority programs as part of the 
Executive Order.[Footnote 37] Additionally, OMB established a Web site 
(www.PaymentAccuracy.gov) on the 14 high-priority programs that 
provides information on (1) the programs' senior accountable officials 
responsible for efforts to reduce improper payments; (2) current, 
targeted, and historical estimated rates of improper payments; (3) why 
improper payments occur in the programs; and (4) what federal agencies 
are doing to reduce improper payments and recover overpayments. 

To supplement program integrity efforts, the Medicare Prescription 
Drug, Improvement, and Modernization Act of 2003 directed CMS to 
conduct a 3-year demonstration project on the use of a new type of 
contractors--recovery audit contractors (RAC)--in identifying 
underpayments and overpayments, and recouping overpayments in the 
Medicare program.[Footnote 38] The RAC demonstration program began in 
2005. Subsequently, the Tax Relief and Health Care Act of 2006 
required CMS to implement a national RAC program by January 1, 2010. 
[Footnote 39] CMS began implementing it in March 2009. 

In March 2010, the President issued a memorandum intended to expand 
agency efforts to recapture improper overpayments using recapture 
audits.[Footnote 40] Also, the Patient Protection and Affordable Care 
Act (PPACA),[Footnote 41] as amended by the Health Care and Education 
Reconciliation Act of 2010,[Footnote 42] contains provisions intended 
to improve accountability over Medicare. These provisions include: 

* establishing procedures for screening providers enrolling in 
Medicare, including assessing the risk levels of fraud, waste, and 
abuse by categories of providers; 

* expanding the Medicare RAC program to Medicare Advantage and 
Medicare prescription drug benefit program; 

* adding requirements for providers to disclose any current or 
previous affiliation with a provider that has uncollected debt; has 
been or is subject to a payment suspension under a federal health care 
program; has been excluded from participation under Medicare, 
Medicaid, or the Children's Health Insurance Program or has had its 
billing privileges denied or revoked; 

* expanding the number of areas to be included in the competitive 
bidding program for durable medical equipment; and: 

* strengthening the Health Care Fraud and Abuse Control Program, a 
joint effort of the HHS Inspector General and the Department of 
Justice, which is designed to coordinate law enforcement activities 
regarding health care fraud and abuse, including that in Medicare. 

In June 2010, the President announced that the Administration would 
reduce the error rate for the Medicare fee-for-service program by half 
by fiscal year 2012. Also, the President directed agencies to check 
certain databases--known as the "Do Not Pay List"--before making 
payments to ensure payments did not go to individuals who were 
deceased or excluded from receiving federal payments or to entities 
that had been excluded from receiving federal payments. 

In addition to amending the Improper Payments Information Act of 2002 
(IPIA)[Footnote 43] improper payment estimation requirements, the 
Improper Payments Elimination and Recovery Act of 2010 (IPERA) 
[Footnote 44] established additional requirements related to (1) 
federal agency management accountability; (2) recovery auditing aimed 
at identifying and reclaiming payments made in error; (3) compliance 
and noncompliance determinations based on an inspector general's 
assessment of an agency's adherence to IPERA requirements, and 
reporting that determination; and (4) an opinion on internal controls 
over improper payments. OMB issued IPERA implementing guidance on 
April 14, 2011.[Footnote 45] 

The Small Business Jobs Act of 2010 also contains a provision 
regarding claims review to prevent improper payments.[Footnote 46] It 
requires CMS to use predictive modeling and other analytic techniques--
known as predictive analytic technologies--both to identify and to 
prevent improper payments under the Medicare fee-for-service program. 
The law requires these predictive analytic technologies to be used to 
analyze and identify Medicare provider networks, billing patterns, and 
beneficiary utilization patterns and detect those that represent a 
high risk of fraudulent activity. Through such analysis, unusual or 
suspicious patterns or abnormalities could be identified that could be 
used to prioritize additional review of suspicious transactions before 
payment is made.

GAO's Mission: 

The Government Accountability Office, the audit, evaluation and 
investigative arm of Congress, exists to support Congress in meeting 
its constitutional responsibilities and to help improve the performance 
and accountability of the federal government for the American people. 
GAO examines the use of public funds; evaluates federal programs and 
policies; and provides analyses, recommendations, and other assistance 
to help Congress make informed oversight, policy, and funding 
decisions. GAO's commitment to good government is reflected in its core 
values of accountability, integrity, and reliability.
