What GAO Found
In the 10 selected states reviewed, GAO found the use of varying types of information technology (IT) systems to support efforts to prevent and detect improper payments. All 10 states had implemented a Medicaid Management Information System (MMIS) to process claims and support their program integrity efforts, and 7 had implemented additional types of systems to meet specific needs. Three states were operating MMISs that were implemented more than 20 years ago, but 7 states had upgraded their MMISs, and 2 of those had done so in the past 2 years. In addition, 7 states had implemented other systems, such as data analytics and decision support systems that enabled complex reviews of multiple claims and identification of providers' billing patterns that could be fraudulent. While the MMISs and other systems implemented by the 10 states were designed primarily for administering Medicaid as a fee-for-service program, in which providers file claims for reimbursement for each service delivered to patients, officials with 7 of the 10 states also administered managed care plans–plans for which provider organizations are reimbursed based on a fixed amount each month–and 1 state administered Medicaid exclusively as managed care. Officials with the 9 states who administered fee-for-service plans said they used their systems to help conduct pre- and post-payment reviews of claims.
All 10 states received technical and financial support from the Centers for Medicare & Medicaid Services (CMS) for implementing the systems. For example, they accessed the agency's databases to collect information that helped determine providers' eligibility to enroll in Medicaid. In addition, all 10 states had participated in training, technical workgroups, and collaborative sessions facilitated by CMS. With the agency's approval, the 10 states received up to 90 percent in federal matching funds to help implement systems. All 10 states reported that agency support, particularly training, helped them to implement systems needed to prevent and detect improper payments.
However, the effectiveness of the states' use of the systems for program integrity purposes is not known. CMS does not require states to measure or report quantifiable benefits achieved as a result of using the systems; accordingly, only 3 of the 10 selected states measured benefits. Without identifying and measuring such benefits (i.e., money saved or recovered) that result from using MMISs and other systems, CMS and the states cannot be assured of the systems' effectiveness in helping to prevent and detect improper payments. Moreover, without requiring states to institute approaches for measuring and reporting such outcomes, CMS officials lack an essential mechanism for ensuring that the federal financial assistance that states receive to help fund these systems effectively supports Medicaid program integrity efforts.
Five of the 10 states faced challenges with using systems for managed care program integrity–introduced by the content, quality, and definitions of data on services provided. However, 1 state had taken steps to overcome such challenges and had integrated data and implemented functionality needed to review managed care data both prior to and after payment. For its part, CMS had conducted training related specifically to collecting and analyzing these data to help prevent and detect improper payments in the Medicaid program.
Why GAO Did This Study
Medicaid is a joint federal-state program that provides health care coverage to certain low-income individuals. The program is overseen by CMS, while the states that administer Medicaid are tasked with taking actions to ensure its integrity. Such actions include implementing IT systems that provide program integrity analysts with capabilities to assess claims, provider, beneficiary, and other data relevant to Medicaid; and supporting efforts to prevent and detect improper payments to providers.
GAO was asked to review states' implementation of IT systems that support Medicaid. GAO determined (1) the types and implementation status of the systems used by states to support program integrity initiatives; (2) the extent to which CMS is making available data, technical resources, and funds to support Medicaid programs' efforts to implement systems, and the effectiveness of the states' systems; and (3) key challenges that Medicaid programs have faced in using IT to enhance program integrity initiatives, and CMS's actions to support efforts to overcome them. To do this, GAO analyzed information from 10 selected states covering a range of expenditures on such systems, reviewed program management documentation, and interviewed CMS officials.
What GAO Recommends
GAO recommends that CMS require states to measure and report quantifiable benefits of program integrity systems when requesting federal funds, and to reflect their approach for doing so. The agency agreed with the recommendation.
Recommendation for Executive Action
Status: Closed - Not Implemented
Comments: In comments on our report, agency officials agreed with this recommendation and provided information on CMS's plans to use a template to track cost savings resulting from state Medicaid offices' use of information systems for program integrity purposes. In April 2017, CMS officials said that they were no longer planning to use the template to gather information from the states, because of the varied approaches that states take to implement systems support for program integrity purposes. The officials stated that they were developing an alternative approach for capturing this information from the states, which would be provided to us when completed. However, in December 2017 and in July 2018, CMS officials stated that they no longer concur with the recommendation we made in March 2015 and do not intend to take actions to address the recommendation. They stated that the agency is taking steps to reduce the regulatory and reporting burden for states and that requiring states to measure benefits achieved as a result of implementing systems for program integrity and other purposes is not feasible. While we still believe that requiring states to measure whether the potentially billions of dollars of federal funds spent to support Medicaid program integrity efforts result in savings, we are closing the recommendation as unimplemented.
Recommendation: To ensure that the federal government's and states' investments in information systems result in outcomes that are effective in supporting efforts to save funds through the prevention and detection of improper payments in the Medicaid program, the Secretary of Health and Human Services should direct the Administrator of CMS to require states to measure quantifiable benefits, such as cost reductions or avoidance, achieved as a result of operating information systems to help prevent and detect improper payments. Such measurement of benefits should reflect a consistent and repeatable approach and should be reported when requesting approval for matching federal funds to support ongoing operation and maintenance of systems that were implemented to support Medicaid program integrity purposes.
