Highlights of GAO-12-288T, a testimony before the Subcommittees on 
Government Organization, Efficiency and Financial Management and 
Health Care, District of Columbia, Census and the National Archives, 
Committee on Oversight and Government Reform, House of Representatives. 

Why GAO Did This Study: 

The Centers for Medicare & Medicaid Services (CMS), the federal agency 
that oversees Medicaid, estimated that improper payments in the 
federal-state Medicaid program were $21.9 billion in fiscal year 2011. 
The Deficit Reduction Act of 2005 established the Medicaid Integrity 
Program and gave CMS an expanded role in assisting and improving the 
effectiveness of state activities to ensure proper payments. Making 
effective use of this expanded role, however, requires that federal 
resources are targeted appropriately and do not duplicate state 
activities. 

GAO was asked to testify on Medicaid program integrity. GAO’s 
statement focuses on how CMS’s expanded role in ensuring Medicaid 
program integrity (1) poses a challenge because of overlapping state 
and federal activities regarding provider audits and (2) presents 
opportunities through oversight to enhance state program integrity 
efforts. 

To do this work, GAO reviewed CMS reports and documents on Medicaid 
program integrity as well as its own and others’ reports on this 
topic. In particular, GAO reviewed CMS reports that documented the 
results of its state oversight and monitoring activities. GAO also 
interviewed CMS officials in the agency’s Medicaid Integrity Group 
(MIG), which was established to implement the Medicaid Integrity 
Program. This work was conducted in November and December 2011. GAO 
discussed the facts in this statement with CMS officials. 

What GAO Found: 

The key challenge faced by the Medicaid Integrity Group (MIG) is the 
need to avoid duplication of federal and state program integrity 
efforts, particularly in the area of auditing provider claims. In 
2011, the MIG reported that it was redesigning its national provider 
audit program. Previously, its audit contractors were using incomplete 
claims data to identify overpayments. According to MIG data, 
overpayments identified by its audit contractors since fiscal year 
2009 were not commensurate with its contractors’ costs. The MIG’s 
redesign will result in greater coordination with states on a variety 
of factors, including the data to be used. It remains to be seen, 
however, whether these changes will result in an increase in 
identified overpayments. The table below highlights the MIG’s core 
oversight activities, which were implemented from fiscal years 2007 
through 2009. 

Table: MIG’s Core Oversight Activities and Fiscal Year Implemented: 

MIG activities: Comprehensive program integrity reviews (fiscal year 
2007); 
Description: Every 3 years, the MIG conducts a comprehensive 
management review of each state’s Medicaid program integrity 
procedures and processes. Through the reviews, CMS assesses the 
effectiveness of the state’s program integrity efforts and determines 
whether the state’s policies and procedures comply with federal 
regulations. 

MIG activities: Technical assistance (fiscal year 2007); 
Description: In fiscal year 2009, the MIG responded to 504 requests 
for technical assistance from 49 states, providers, advocates and 
others. Common topics included policy/regulatory requirements on 
disclosures, law enforcement activities, and fraud detection tools. 

MIG activities: Medicaid Integrity Institute (fiscal year 2007); 
Description: The institute is the first national Medicaid integrity 
training program. CMS executed an interagency agreement with the 
Department of Justice to house the institute at the Department’s 
National Advocacy Center, located at the University of South Carolina. 
The institute offers substantive training, technical assistance, and 
support to states in a structured learning environment. 

MIG activities: National Provider Audit Program (fiscal year 2009); 
Description: Separate contractors (1) analyze claims data to identify 
aberrant claims, and potential billing vulnerabilities; and (2) 
conduct post-payment audits based on data analysis leads in order to 
identify overpayments to Medicaid providers. 

MIG activities: State program integrity assessments (fiscal year 2009); 
Description: These annual assessments represent the first national 
baseline collection of data on state Medicaid integrity activities for 
the purposes of program evaluation and technical assistance support. 
The data provided by states are used to populate a one-page profile 
covering topics such as program integrity staffing and expenditures, 
audits, fraud referrals, and recoveries. 

MIG activities: Education contractors (fiscal year 2009); 
Description: The education contractors develop materials in order to 
educate and train providers on payment integrity and quality of care 
issues.

[End of table] 

The MIG’s core oversight activities present an opportunity to enhance 
state efforts through the provision of technical assistance and the 
identification of training opportunities. The MIG’s assessment of 
state program integrity efforts during triennial onsite reviews and 
annual assessments will need to address data inconsistencies 
identified during these two activities. Improved consistency will help 
ensure that the MIG is appropriately targeting its resources. The 
Medicaid Integrity Institute appears to address a state training need 
and create networking opportunities for program integrity staff.

Chairmen Platts, Gowdy, and Members of the Subcommittees: 

I am pleased to be here today to discuss Medicaid program integrity, 
that is, preventing improper payments that result from fraud, waste, 
and abuse.[Footnote 1] Until the Deficit Reduction Act of 2005 (DRA) 
expanded the role of the Centers for Medicare & Medicaid Services 
(CMS), the federal agency that oversees Medicaid, Medicaid program 
integrity had been primarily a state responsibility.[Footnote 2] CMS's 
expanded role presents an opportunity to assist and improve the 
effectiveness of state activities, but also requires that federal 
resources are targeted appropriately and do not duplicate state 
activities. 

Medicaid is jointly funded by federal and state governments. It is one 
of the largest social programs in the federal budget--covering about 
67 million people in fiscal year 2010--and one of the largest 
components of state budgets. In fiscal year 2010, Medicaid 
expenditures totaled about $401 billion, with a federal share of $270 
billion and a state share of $132 billion. As a result of flexibility 
in the program's design, Medicaid consists of 56 distinct state-based 
programs.[Footnote 3] The challenges inherent in overseeing a program 
of Medicaid's size and diversity make the program vulnerable to 
improper payments, which may be the result of fraud, waste, and abuse. 
[Footnote 4] Because of the program's risk of improper payments as 
well as insufficient federal and state oversight, we added Medicaid to 
our list of high-risk programs in January 2003.[Footnote 5] CMS 
estimated that Medicaid improper payments were $21.9 billion for 
fiscal year 2011.[Footnote 6] 

States are the first line of defense against Medicaid improper 
payments. Specifically, they must comply with federal requirements to 
ensure the qualifications of the providers who bill the program, 
detect improper payments, recover overpayments, and refer suspected 
cases of fraud and abuse to law enforcement authorities. At the 
federal level, CMS, an agency within the Department of Health and 
Human Services (HHS), is responsible for supporting and overseeing 
state Medicaid program integrity activities. 

In 2005, we testified that CMS needed to increase its commitment--both 
the alignment of resources and strategic planning--to helping states 
fight Medicaid fraud, waste and abuse.[Footnote 7] Subsequently, the 
DRA established the Medicaid Integrity Program and included other 
provisions designed to increase CMS's support for state activities to 
address Medicaid fraud, waste, and abuse. The DRA provided 
appropriations to implement the Medicaid Integrity Program, and the 
Patient Protection and Affordable Care Act (PPACA) enacted in March 
2010 gave CMS and states additional provider and program integrity 
oversight tools.[Footnote 8] 

You asked GAO to testify today on Medicaid program integrity. My 
remarks focus on how CMS's expanded role in ensuring Medicaid program 
integrity (1) poses a challenge because of overlapping state and 
federal activities, particularly in the area of auditing provider 
claims; and (2) presents opportunities through oversight to enhance 
state program integrity efforts. To do this work, we reviewed CMS 
reports and documents on Medicaid program integrity as well as our own 
and others' reports on this topic. In particular, we reviewed CMS 
reports that documented the results of its state oversight and 
monitoring activities. We also interviewed CMS officials in the 
agency's Medicaid Integrity Group, which was established to implement 
the Medicaid Integrity Program. We conducted our work in November and 
December 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. The data presented in this statement were obtained from 
CMS and we did not independently verify their reliability. We believe 
that the evidence obtained provides a reasonable basis or our findings 
and conclusions based on our audit objectives. 

Background: 

CMS is responsible for overseeing Medicaid and state Medicaid agencies 
are responsible for administering the program. Although each state is 
subject to federal requirements, it develops its own Medicaid 
administrative structure for carrying out the program including its 
approach to program integrity. Within broad federal guidelines, each 
state establishes eligibility standards and enrolls eligible 
individuals; determines the type, amount, duration, and scope of 
covered services; sets payment rates for covered services; establishes 
standards for providers and managed care plans; and ensures that state 
and federal funds are not spent improperly or diverted by fraudulent 
providers. However, state Medicaid programs do not work in isolation 
on program integrity; instead, there are a large number of federal 
agencies, other state entities, and contractors with which states must 
coordinate. 

State Medicaid Program Integrity Activities: 

Generally, each state's Medicaid program integrity unit uses its own 
data models, data warehouses, and approach to analysis. States often 
augment their in-house capabilities by contracting with companies that 
specialize in Medicaid claims and utilization reviews. However, as 
program administrators, states have primary responsibility for 
conducting program integrity activities that address provider 
enrollment, claims review, and case referrals. Specifically, CMS 
expects states to: 

* collect and verify basic information on providers, including whether 
the providers meet state licensure requirements and are not prohibited 
from participating in federal health care programs: 

* maintain a mechanized claims processing and information system known 
as the Medicaid Management Information System (MMIS). MMIS can be used 
to make payments and to verify the accuracy of claims, the correct use 
of payment codes, and a beneficiary's Medicaid eligibility.[Footnote 9] 

* operate a Surveillance and Utilization Review Subsystem (SURS) in 
conjunction with the MMIS that is intended to develop statistical 
profiles on services, providers, and beneficiaries in order to 
identify potential improper payments. For example, SURS may apply 
automatic post-payment screens to Medicaid claims in order to identify 
aberrant billing patterns. 

* submit all processed Medicaid claims electronically to CMS's Medical 
Statistical Information System (MSIS). MSIS does not contain billing 
information, such as the referring provider's identification number or 
beneficiary's name, because it is a subset of the claims data 
submitted by states. States provide data on a quarterly basis and CMS 
uses the data to (1) analyze Medicaid program characteristics and 
utilization for services covered by state Medicaid programs, and (2) 
generate various public use reports on national Medicaid populations 
and expenditures. 

* refer suspected overpayments or overutilization cases to other units 
in the Medicaid agency for corrective action and refer potential fraud 
cases to other appropriate entities for investigation and prosecution. 

Our reports and testimonies from 2001 through 2006 identified gaps in 
state program integrity activities and noted that the support provided 
by CMS to states was hampered by resource constraints.[Footnote 10] 
For example, in 2004, we reported that 15 of 47 states responding to 
our questionnaire did not affirm that they conducted data mining, 
defined as analysis of large data sets to identify unusual utilization 
patterns, which might indicate provider abuse. 

Recent Legislation Has Conferred New Responsibilities on CMS and 
States: 

The DRA established the Medicaid Integrity Program to provide 
effective federal support and assistance to states to combat fraud, 
waste, and abuse. To implement the Medicaid Integrity Program, CMS 
created the Medicaid Integrity Group (MIG), which is now located 
within the agency's Center for Program Integrity. The DRA also 
required CMS to hire contractors to review and audit provider claims 
and to educate providers on issues such as appropriate billing 
practices. 

The Medicaid Recovery Audit Contractor (RAC) program was established 
by PPACA.[Footnote 11] Each state must contract with a RAC, which is 
tasked with identifying and recovering Medicaid overpayments and 
identifying underpayments. Each state's RAC is required to be 
operational by January 1, 2012. Medicaid RACs will be paid on a 
contingency fee basis--up to 12.5 percent--of any recovered 
overpayments and states are required to establish incentive payments 
for the detection of underpayments.[Footnote 12] Figure 1 identifies 
the key federal and state entities responsible for Medicaid program 
integrity.

Fraud Investigation and Prosecution: 

Fraud detection and investigations often require more specialized 
skills than are required for the identification of improper payments 
because investigators must establish that an individual or entity 
intended to falsify a claim to achieve some gain. As a result, fraud 
is more difficult to prove than improper payments and requires the 
involvement of entities that can investigate and prosecute fraud 
cases. In 1977, Congress authorized federal matching funds for the 
establishment of independent state Medicaid Fraud Control Units 
(MFCU).[Footnote 13] MFCUs are responsible for investigating and 
prosecuting Medicaid fraud. In general, they are located in State 
Attorneys Generals' offices. MFCUs can, in turn, refer some cases to 
federal agencies that have longstanding responsibility for combating 
fraud, waste, and abuse in Medicare and Medicaid--the HHS's Office of 
Inspector General (HHS-OIG), the Federal Bureau of Investigation 
(FBI), and the Department of Justice. 

CMS's MIG Implemented Core Activities from 2006 through 2009 but 
Effective Coordination Is Needed Because of Overlap with Ongoing State 
Efforts: 

A key challenge CMS faces in implementing the statutorily required 
federal Medicaid Integrity Program is ensuring effective coordination 
to avoid duplicating state program integrity efforts. CMS established 
the MIG in 2006 and it gradually hired staff and contractors to 
implement a set of core activities, including the (1) review and audit 
of Medicaid provider claims; (2) education of state program integrity 
officials and Medicaid providers; and (3) oversight of state program 
integrity activities and provision of assistance. Because states also 
routinely review and audit provider claims, the MIG recognized that 
coordination was key to avoiding duplication of effort. In 2011, the 
MIG reported that it was redesigning its national provider audit 
program to allow for greater coordination with states on data, 
policies, and audit measures. According to MIG data, overpayments 
identified by its review and audit contractors over the first 3 years 
of the national audit program were not commensurate with the 
contractors' costs. 

Core MIG Activities Were Implemented Gradually from 2006 to 2009: 

The DRA provided CMS with the resources to hire staff whose sole 
duties are to assist states in protecting the integrity of the 
Medicaid program. The MIG's core activities were implemented gradually 
from fiscal year 2006 to 2009. The DRA provided start up funding of $5 
million for fiscal year 2006, increasing to $50 million for each of 
the subsequent 2 fiscal years, and $75 million per year for fiscal 
year 2009 and beyond.[Footnote 14] One of the first activities 
initiated by the MIG in fiscal year 2007 was comprehensive program 
integrity reviews to assess the effectiveness of states' activities, 
which involved eight, week-long onsite visits that year.[Footnote 15] 
One of the last activities to be implemented was the statutorily 
required National Provider Audit Program where MIG contractors review 
and audit Medicaid provider claims. In fiscal year 2005, we reported 
that CMS devoted 8.1 full time equivalent staff years to support and 
oversee states' anti-fraud-and-abuse operations, which, in 2010, had 
grown to 83 out of the 100 DRA authorized full time equivalent staff 
years.[Footnote 16] Table 1 describes six core MIG activities and the 
fiscal year in which those activities began. 

Table 1: Medicaid Integrity Group's Core Oversight Activities, by 
Fiscal Year Implemented: 

Fiscal year 2007: 

MIG activities: Comprehensive program integrity reviews; 
Description: Every 3 years, the MIG conducts a comprehensive 
management review of each state's Medicaid program integrity 
procedures and processes. Through the reviews, the MIG assesses the 
effectiveness of the state's program integrity efforts and determines 
whether the state's policies and procedures comply with federal 
statutes and regulations. The review areas include provider 
enrollment, provider disclosures, program integrity, managed care 
operations, and the interaction between the state's Medicaid agency 
and its Medicaid Fraud Control Unit (MFCU). Each review results in a 
report which is posted on CMS's Web site that summarizes best 
practices, compliance issues, and vulnerabilities. The MIG also 
conducts follow-up reviews to evaluate state's corrective action plans 
addressing any identified vulnerabilities. 

MIG activities: Technical assistance; 
Description: In fiscal year 2009, the MIG responded to 504 requests 
for technical assistance from 49 states, providers, advocates and 
others. Common topics included the National Provider Audit Program, 
policy/regulatory requirements on disclosures, law-enforcement 
activities, and fraud detection tools. Examples of other assistance 
provided to the states included (1) hosting regional State Program 
Integrity Director conference calls to discuss emerging issues and 
best practices, and (2) issuing a State Medicaid Director letter in 
January 2009 which provided guidance to Medicaid providers on 
screening their employees and contractors for individuals excluded 
from participation in the program. 

MIG activities: Medicaid integrity institute; 
Description: The institute is the first national Medicaid integrity 
training program. CMS executed an interagency agreement with the 
Department of Justice to house the institute at the National Advocacy 
Center, located at the University of South Carolina. The institute 
offers substantive training, technical assistance, and support to 
states in a structured learning environment. In time, the institute 
intends to create a credentialing process to elevate the professional 
qualifications of state Medicaid program integrity staff. 

Fiscal year 2009: 

MIG activities: National Provider Audit Program[A]; 
Description: Separate contractors (1) analyze claims data to identify 
aberrant claims and potential billing vulnerabilities, and (2) conduct 
post-payment audits based on data analysis leads in order to identify 
overpayments to Medicaid providers. 

MIG activities: State program integrity assessments; 
Description: These annual assessments represent the first national 
baseline collection of data on state Medicaid integrity activities for 
the purposes of program evaluation and technical assistance support. 
The data provided by states are used to populate a one page profile 
covering topics such as program integrity staffing and expenditures, 
audits, fraud referrals to the state's MFCU, and recoveries. 

MIG activities: Education contractors; 
Description: The education contractors develop materials in order to 
educate and train providers on payment integrity and quality of care 
issues.

[A] To gain a better understanding of audit processes and procedures 
as well as variation across the states, the MIG initiated test audits 
in fiscal year 2007, prior to the implementation of the National 
Provider Audit Program.

Figure 2 shows MIG expenditures by program category for fiscal year 
2010. The Medicaid Integrity Institute accounted for about 2 percent 
of the MIG's fiscal year 2010 expenditures, while the National 
Provider Audit Program accounted for about half of expenditures.

The MIG Recognized the Need for Effective Coordination: 

At the outset, the MIG recognized that effective coordination with 
internal and external stakeholders was essential to the success of the 
Medicaid Integrity Program. In a report issued prior to establishment 
of the program, we found that CMS had a disjointed organizational 
structure and lacked the strategic planning necessary to face the 
risks involved with the Medicaid program.[Footnote 17] We identified 
the need for CMS to develop a strategic plan in order to provide 
direction to the agency, its contractors, states, and its law 
enforcement partners. In designing and implementing the program, the 
MIG convened an advisory committee consisting of (1) state program 
integrity, Medicaid, and MFCU directors from 16 states; and (2) 
representatives of the FBI, HHS-OIG, and CMS regional offices. This 
committee provided planning input and strategic advice and identified 
key issues that the MIG needed to address, including: 

* The MIG's efforts should support and complement states' Medicaid 
integrity efforts, not be redundant of existing auditing efforts. 

* Program integrity activities of the MIG and other federal entities 
require coordination with states regarding auditing and data requests. 

* The focus of state activities should be shifted from postpayment 
audits to prepayment prevention activities. 

The advisory committee also highlighted the lack of state resources 
for staffing, technology, and training. CMS's July 2009 Comprehensive 
Medicaid Integrity Plan, the fourth such plan since 2006, stated that 
fostering collaboration with internal and external stakeholders of the 
Medicaid Integrity Program was a primary goal of the MIG. 

In implementing more recent statutory requirements, CMS again stressed 
the need for effective coordination and collaboration. CMS's 
commentary accompanying the final rule on the implementation of 
Medicaid RACs acknowledged the potential for duplication with states' 
ongoing efforts to identify Medicaid overpayments. States have been 
responsible for the recovery of all identified overpayments, including 
those identified since fiscal year 2009 by the MIG's audit 
contractors. The new requirement for states to contract with an 
independent Medicaid RAC introduces another auditor to identify and 
collect Medicaid overpayments. The Medicaid RAC program was modeled 
after a similar Medicare program, which was implemented in March 2009 
after a 3-year demonstration.[Footnote 18] Because Medicare RACs are 
paid a fixed percentage of the dollar value of any improper payments 
identified, they generally focused on costly services such as 
inpatient hospital stays. Our prior work on Medicare RACs noted that 
the postpayment review activities of CMS's other contractors would 
overlap less with the RACs' audits if those activities focused on 
different Medicare services where improper payments were known to be 
high, such as home health.[Footnote 19] Because Medicaid RACs are not 
required to be operational until January 1, 2012, the extent to which 
states will structure their RAC programs to avoid duplication and 
complement their own provider review and audit activities remains to 
be seen. 

The MIG Is Redesigning the National Provider Audit Program, Whose 
Returns Were Not Commensurate with Contractors' Costs: 

In its most recent annual report to the Congress, the MIG indicated 
that it was redesigning the National Provider Audit Program. According 
to the MIG, the National Provider Audit Program has not identified 
overpayments in the Medicaid program commensurate with the related 
contractor costs. About 50 percent of the MIG's $75 million annual 
budget supports the activities of its review and audit contractors. 
From fiscal years 2009 through 2011, the MIG authorized 1,663 provider 
audits in 44 states. However, the MIG's reported return on investment 
from these audits was negative. While its contractors identified $15.2 
million in overpayments, the combined cost of the National Provider 
Audit Program was about $36 million in fiscal year 2010. The actual 
amount of overpayments recovered is not known because states are 
responsible for recovering overpayments and the MIG is not the CMS 
entity that tracks recoveries. Actual recoveries may be less than the 
identified overpayments. 

The National Provider Audit Program has generally relied on MSIS, 
which is summary data submitted by states on a quarterly basis that 
may not reflect voided or adjusted claims payments. As a result, the 
MIG's audit contractors may identify two MSIS claims as duplicates 
when the state has already voided or denied payment on one of these 
claims. For their program integrity efforts, states use their own MMIS 
data systems, which generally reflect real-time payments and 
adjustments of detailed claims for each health care service. States 
are required to have a SURS component that performs data mining as a 
part of their program integrity efforts. The MIG's review contractors 
use data mining techniques that may be similar to those employed by 
states, and they may not identify any additional improper claims. 

Moreover, MIG officials told us that the National Provider Audit 
Program did not prioritize the activities according to the dollar 
amount of the claim, that is, it did not concentrate its efforts on 
audits with the greatest potential for significant recoveries. 
Although the amount of overpayment identified from any given audit can 
vary by thousands or millions of dollars, the MIG's comprehensive 
reviews of several states' Medicaid integrity programs show that these 
states identified significantly higher levels of overpayments in 1 
year than the National Provider Audit Program identified over 3 years. 
For example, the number of national provider audits (1,663) over three 
fiscal years was similar to the number that New York conducted in 
fiscal year 2008 (1,352), yet CMS reported that New York had 
identified more than $372 million in overpayments--considerably more 
than the $15.2 million identified through national provider audits. 
[Footnote 20] 

The MIG's proposed redesign of the National Provider Audit Program 
appears to allow for greater coordination between its contractors and 
states on a variety of factors, including the data to be used. 
[Footnote 21] In fiscal year 2010, the MIG launched collaborative 
audits in 13 states. For these audits, the states and the MIG agreed 
on the audit issues to review and, in some cases, states provided the 
MIG's audit contractors with more timely and complete claims data. 
These collaborative projects (1) allowed states to augment their own 
audit resources, (2) addressed audit targets that states may not have 
been able to initiate because of a lack of staff, and (3) provided 
data analytic support for states that lacked that capability. Although 
these activities are ongoing and the results have not yet been 
finalized, such collaborative projects appear to be a promising 
approach to audits that avoids a duplication of federal and state 
efforts. It remains to be seen, however, whether these changes will 
result in an increase in identified overpayments. 

Expanded Role Offers Opportunity to Enhance State Efforts, but More 
Consistent Data Are Needed: 

While the MIG's audit program is challenged to avoid duplicating 
states' own audit activities, its other core functions present an 
opportunity to enhance states' efforts. The MIG's state oversight 
activities are extensive and labor intensive. Although the data 
collected during reviews and assessments are not always consistent 
with each other, these oversight activities have a strong potential to 
inform the MIG's technical assistance and help identify training 
opportunities. The Medicaid Integrity Institute appears to address an 
important state training need. 

MIG's Core Oversight Activities Are Broad, but the Data Collected 
During Reviews and Assessments Were Not Always Consistent with Each 
Other: 

The MIG's core oversight activities--triennial comprehensive state 
program integrity reviews and annual assessments--are broad in scope 
and provide a basis for the development of appropriate technical 
assistance. However, we found that the information collected during 
reviews and the information collected from assessments was sometimes 
inconsistent with each other. 

As of November 2011, the MIG had completed the first round of reviews 
for 50 states and had initiated a second round of reviews in 10 
states. The reviews cover the entirety of a state's program integrity 
activities and assess compliance with federal regulations. In advance 
of the MIG's week-long onsite visit, state program integrity officials 
are asked to respond to a 71-page protocol containing 195 questions 
and to provide considerable documentation.[Footnote 22] Table 2 
summarizes the topics covered in the protocol. Typical compliance 
issues and vulnerabilities identified during the reviews include 
provider enrollment weaknesses, inadequate oversight of providers in 
Medicaid managed care, and ineffective fraud referrals to state MFCUs.

[End of table] 

Much of the information collected during the assessments--Medicaid 
program integrity characteristics, program integrity planning, 
prevention, detection, investigation and recoveries--is also collected 
during the triennial comprehensive reviews.[Footnote 23] In addition, 
we found inconsistencies between the information reported in the 
comprehensive reviews and in the assessments for several states that 
were conducted at about the same time. For example, there was a 
significant discrepancy for one state in the number of staff it 
reported as being dedicated to program integrity activities. According 
to the MIG, knowing the size of state program integrity staff helps it 
to more appropriately tailor content during training events. Improved 
consistency will help the MIG ensure that it is targeting its training 
and technical assistance resources appropriately. Despite the 
frequency of the annual assessments, the most current data cover 
fiscal year 2008, which the MIG began collecting in fiscal year 2010. 

Although the MIG provides states with a glossary explaining each of 
the requested data elements, it is not clear that the information 
submitted is reliable or comparable across states. Our review of a 
sample of assessments revealed missing data and a few implausible 
measures, such as one state reporting over 38 million managed care 
enrollees. In other states, there were dramatic changes in the data 
reported from 2007 to 2008, which either raises a question about the 
reliability of the data or suggests that states be allowed to explain 
significant changes from year to year. For example, the number of 
audits in one state declined from 203 to 35. 

According to MIG officials, the comprehensive reviews and the 
assessments inform the MIG's technical assistance activities with the 
states. For example, we found that the MIG published best practices 
guidance in 2008 after finding weaknesses in coordination between 
state program integrity officials and their respective MFCU's in a 
number of states. In its report to Congress on fiscal year 2010 
activities, the MIG indicated it completed 420 requests for technical 
assistance from 43 states, providers, and others. The most common 
topics included the National Provider Audit Program, policy and 
regulatory requirements on disclosures, provider exclusions and 
enrollment, and requests for statistical assistance related to 
criminal and civil court actions. Examples of assistance provided to 
the states by the MIG included (1) hosting regional state program 
integrity director conference calls to discuss program integrity 
issues and best practices; and (2) helping develop a State Medicaid 
Director Letter (issued in July 2010) on the return of federal share 
of overpayments under PPACA. 

Medicaid Integrity Institute Trains State Staff and Facilitates 
Networking: 

The federally sponsored Medicaid Integrity Institute not only offers 
state officials free training but also provides opportunities to 
develop relationships with program integrity staff from other states. 
The institute addresses our prior finding that CMS did not sponsor any 
fraud and abuse workshops or training from 2000 through 2005.[Footnote 
24] From fiscal years 2008 through 2012, the institute will have 
trained over 2,265 state employees at no cost to states. Given the 
financial challenges states currently face, it is likely that 
expenditures for training and travel are limited. Expenditures on the 
institute accounted for about $1.3 million of the MIG's $75 million 
annual budget. MIG officials told us that states uniformly praised the 
opportunity to network and learn about best practices from other 
states. A special June 2011 session at the institute brought together 
Medicaid program integrity officials and representatives of MFCUs from 
39 states in an effort to improve the working relations between these 
important program integrity partners. 

In addition to the institute, the MIG has a contractor that provides 
(1) education to broad groups of providers and beneficiaries, and (2) 
targeted education to specific providers on certain topics.[Footnote 
25] For example, the education contractor has provided outreach 
through its attendance at 17 conferences with about 36,000 attendees. 
These conferences were sponsored by organizations devoted to combating 
health care fraud such as the National Association of Medicaid Program 
Integrity and National Health Care Anti-Fraud Association, as well as 
meetings of national and regional provider organizations (hospital, 
home care and hospice and pharmacy). An example of a more targeted 
activity is one focused on pharmacy providers. The MIG's education 
contractor is tasked with developing provider education materials to 
promote best prescribing practices for certain therapeutic drug 
classes and remind providers of the appropriate prescribing guidelines 
based on FDA approved labeling. The education program includes some 
face-to-face conversations, mailings to providers, and distribution of 
materials on a website and at conferences and meetings. These 
activities are collaborative efforts with the states so that states 
are: aware of the aberrant providers, participate in the education 
program, and can implement policy changes to address these issues, as 
appropriate. 

We discussed the facts in this statement with CMS officials. 

Chairmen Pratts and Gowdy, this concludes my prepared remarks. I would 
be happy to answer any questions that you or other Members may have.

Footnotes: 

[1] Medicaid is the federal-state program that covers acute health 
care, long-term care, and other services for certain categories of low-
income individuals. 

[2] See Pub. L. No. 109-171, § 6034, 120 Stat. 3, 74-78 (2006). 

[3] The federal government matches states' expenditures for most 
Medicaid services using a statutory formula based on each state's per 
capita income. The 56 Medicaid programs include one for each of the 50 
states, the District of Columbia, Puerto Rico, Samoa, Guam, the 
Commonwealth of the Northern Mariana Islands, and the United States 
Virgin Islands. 

[4] Fraud involves an intentional act or representation to deceive 
with the knowledge that the action or representation could result in 
gain. Waste results from clerical errors or the provision of medically 
unnecessary services. Abuse typically involves actions that are 
inconsistent with acceptable business and medical practices that 
result in unnecessary program costs. See, e.g., 42 C.F.R. § 455.2 
(2010).

[6] In its Fiscal Year 2011 Agency Financial Report, HHS calculated 
and reported the 3-year (2009, 2010, and 2011) weighted average 
national payment error rate for Medicaid of 8.1 percent. See 
Department of Health and Human Services FY 2011 Agency Financial 
Report (Washington, D.C.: Nov. 15, 2011).

Education Reconciliation Act of 2010 (HCERA), Pub. L. No. 111-152, 124 
Stat. 1029. For example, PPACA required states to have Medicaid 
Recovery Audit Contractors, increased provider ownership reporting 
requirements, and allowed CMS to suspend payments to providers on the 
basis of a credible allegation of fraud. 

[9] States provide CMS with claims data for use in estimating a 
Medicaid payment error rate. CMS developed the Payment Error Rate 
Measurement program to comply with the Improper Payments Information 
Act of 2002. The error rate is not a "fraud rate" but simply a 
measurement of payments made that did not meet statutory, regulatory, 
or administrative requirements.
