What GAO Found

The 10 new demonstrations GAO examined expanded states' use of federal funds and implemented new coverage strategies. Arizona and Texas established funding pools to make new supplemental payments beyond what they could have made under traditional Medicaid requirements and receive federal matching funds for the payments. All 10 demonstrations were approved to use different coverage strategies or impose new cost sharing requirements, including limiting benefits or imposing deductibles for certain populations.

The Department of Health and Human Services' (HHS) budget neutrality policy and process did not provide assurances that all recently approved demonstrations will be budget neutral. For 4 of 10 demonstrations GAO reviewed, HHS approved spending limits that were based on assumptions of cost growth that were higher than its benchmark rates, and that, in some cases, included costs states never incurred in their base year spending. HHS's benchmark growth rates are the lower of the state's recent growth rates or projections for Medicaid program growth nationwide. For example, HHS approved a spending limit for Arizona's demonstration using outdated information on spending--1982 data that was projected forward--that reflected significantly higher spending than what the state's Medicaid program had actually cost. For Texas, HHS approved a spending limit using a base year that included billions in costs the state had not incurred. GAO found limited support and documentation for the higher-than-benchmark limits HHS approved. If HHS had held the 4 demonstrations' spending to levels suggested by its policy, the 5-year spending limits would have been an estimated $32 billion lower than what was approved; the estimated federal share of this reduction would be about $21 billion.

For 6 other demonstrations, the approved spending limits reflected the states' actual historical costs or criteria that were specified in law, which HHS followed. In examining HHS's current written budget neutrality policy, GAO found that the policy is outdated and does not include a process for assuring the reliability of the data used to set spending limits. GAO has previously suggested that Congress require HHS to improve its budget neutrality process, in part, by improving the review criteria and methods, and by documenting and making clear the basis for approved limits. In addition to these suggestions, GAO believes HHS needs to take further actions to address the findings in this report.

Why GAO Did This Study

Medicaid, a $436 billion federal and state health care program for low-income individuals and families, is a significant and growing expenditure. Section 1115 of the Social Security Act authorizes the Secretary of Health and Human Services to waive certain Medicaid requirements and allow otherwise uncovered costs for demonstration projects that are likely to promote Medicaid objectives. By HHS policy, these demonstrations should be budget neutral, that is, not increase federal spending over what it would have been if the state's existing program had continued. States estimate what their spending would have been without the demonstration, and HHS approves a spending based on projected spending.

GAO was asked to review HHS approval of recent Medicaid section 1115 demonstrations. GAO examined (1) the purpose of new demonstrations, and (2) the extent to which HHS's policy and process for reviewing proposed demonstration spending provide assurances that federal costs will not increase. For 10 new comprehensive demonstrations approved from January 2007 through May 2012, GAO reviewed application, approval, and budget neutrality documents provided by HHS; calculated estimated spending limits; and interviewed HHS officials.

Recommendations

GAO recommends that HHS update its budget neutrality policy and reexamine spending limits for the Arizona and Texas demonstrations. HHS disagreed with GAO's recommendations. GAO believes these steps are needed to improve the budget neutrality process.

Recommendations for Executive Action

Agency Affected Recommendation Status
Department of Health and Human Services
Priority Rec.
This is a priority recommendation.
1. To improve the transparency of the process for reviewing and approving spending limits for comprehensive section 1115 demonstrations, the Secretary of Health and Human Services should update the agency's written budget neutrality policy to reflect actual criteria and processes used to develop and approve demonstration spending limits, and ensure the policy is readily available to state Medicaid directors and others.
Closed - Implemented
In August 2018, the Centers for Medicare & Medicaid Services issued written guidance on the process and criteria the agency uses to develop and approve Section 1115 demonstrations. The guidance was communicated as a State Medicaid Directors Letter and is available on the CMS website. The State Medicaid Director Letter addresses the recommendation by describing the process and documenting methods the agency revised in 2016 to curtail some problematic methods. The earlier policy had not been issued and documented as State Medicaid Director Letter. We have closed this recommendation as implemented, and will continue to track how CMS applies this guidance.
Department of Health and Human Services 2. To improve the transparency of the process for reviewing and approving spending limits for comprehensive section 1115 demonstrations, the Secretary of Health and Human Services should reconsider adjustments and costs used in setting the spending limits for the Arizona and Texas demonstrations, and make appropriate adjustments to spending limits for the remaining years of each demonstration.
Open
As of January 2021, the Department of Health and Human Services (HHS) has taken steps to address GAO's 2013 recommendation, but more actions are needed for GAO to consider this recommendation implemented. In May 2016, the Centers for Medicare & Medicaid Services (CMS) began implementing a new budget neutrality policy. The policy was outlined in a Letter to State Medicaid Directors in 2018, and it addressed certain problems GAO identified regarding states' allowed methods for determining budget neutrality of their demonstrations. CMS has begun phasing in the methods established under this new policy for all states, including the two states (Arizona and Texas) for which GAO recommended adjustments. One portion of the policy--under which spending limits will be updated to reflect more recent spending data--will be implemented beginning in 2021, and it will address concerns GAO identified in Arizona's spending limit once its demonstration is renewed. CMS officials told us in December 2020 that the agency has yet to implement the cost-rebasing requirement previously scheduled to begin January 2021. However, other actions are needed for GAO to consider this recommendation implemented. In particular, CMS officials told GAO in January 2019 that the agency continues to allow states to include hypothetical costs when determining demonstration spending limits, an action GAO identified as a concern in Texas' demonstration. In December 2020, CMS confirmed that the agency continues to allow hypothetical costs in states' waiver estimates.
