Exploring the Growth of Medicaid Managed Care

States typically use two types of payment system to provide Medicaid benefits: fee-for-service (FFS) and managed care. In FFS Medicaid, the state reimburses health care providers for the services they deliver to beneficiaries. In contrast, in Medicaid managed care, states pay private health insurance plans or provider groups (called managed care organizations or MCOs) to provide services to enrollees. In this presentation, we use individual-level data to examine trends in the proportion of Medicaid beneficiaries who receive benefits through managed care and the proportion of Medicaid spending that consists of payments for managed care. We also use qualitative data about state programs’ characteristics to examine the changes in state policies that have affected enrollment in and spending for Medicaid managed care.
From 1999 to 2012, the share of Medicaid beneficiaries enrolled in managed care grew from 64 percent to 89 percent. The share of Medicaid spending attributed to payments for managed care was much smaller, however, rising from 15 percent to 37 percent during that period. The percentage of beneficiaries enrolled in managed care exceeds the percentage of Medicaid spending that pays for managed care for three main reasons. First, although many beneficiaries are enrolled in MCOs that cover a broad range of benefits (under “comprehensive” Medicaid managed care programs), many of those beneficiaries receive some benefits through FFS Medicaid. Second, many beneficiaries are enrolled in MCOs that cover only a narrow range of benefits and receive most of their services through FFS Medicaid. Third, enrollment in managed care is more common among beneficiaries in eligibility groups that have lower average Medicaid spending.
Medicaid managed care grew primarily because state policies expanded the scope of comprehensive managed care programs in three ways. First, comprehensive managed care programs became more likely to cover an entire state rather than only certain counties, cities, or regions. Second, mandatory enrollment in comprehensive managed care became more common among all eligibility groups. Third, states increased the scope of services included in their contracts with MCOs; the most pronounced increases occurred for long-term services.

Exploring the Growth of Medicaid Managed Care

  1. 1. Congressional Budget Office Association for Public Policy Analysis & Management Fall Research Conference November 2, 2017 Alice Burns, Ben Layton, Noelia Duchovny, and Lyle Nelson Health, Retirement, and Long-Term Analysis Division The information in this presentation is preliminary and is being circulated to stimulate discussion and critical comment as developmental work for analysis for the Congress. Exploring the Growth of Medicaid Managed Care
  2. 2. 1CONGRESSIONAL BUDGET OFFICE Medicaid is a federal–state program that provides health benefits to over 70 million low-income individuals and accounted for $348 billion of federal spending and $205 billion in state spending in fiscal year 2015.
  3. 3. 2CONGRESSIONAL BUDGET OFFICE States typically use two payment systems: fee-for-service (FFS) and Medicaid managed care (MMC). States may adopt MMC to:  Increase predictability of spending or  Improve coordination of care, which may reduce costs or improve outcomes.
  4. 4. 3CONGRESSIONAL BUDGET OFFICE This project aims to improve our understanding of:  Whether MMC is “the predominant delivery system in Medicaid” and  How and why MMC has grown over time. The project will therefore inform expectations for future growth.
  5. 5. 4CONGRESSIONAL BUDGET OFFICE Key to understanding the growth in MMC is understanding the difference between the percentage of Medicaid enrollment in MMC and the percentage of Medicaid spending that is attributed to payments for MMC.
  6. 6. 5CONGRESSIONAL BUDGET OFFICE Percentage of Total Medicaid Enrollment and Spending Accounted for by MMC 0% 20% 40% 60% 80% 100% 1999 2001 2003 2005 2007 2009 2011 Enrollment Spending
  7. 7. 6CONGRESSIONAL BUDGET OFFICE A major challenge to understanding the growth of MMC is the variation in state programs and the lack of systematic data. We constructed and plan to disseminate a new dataset to support comparisons of states’ MMC programs.
  8. 8. 7CONGRESSIONAL BUDGET OFFICE Beneficiaries’ Enrollment in and Spending on Medicaid Managed Care
  9. 9. 8CONGRESSIONAL BUDGET OFFICE CBO used Medicaid Analytic eXtract data on beneficiaries’ spending and enrollment from 1999 to 2012 (the most recent period for which the data were available). Analyses included beneficiaries who were eligible for full Medicaid benefits.

Such considerations have significant implications for developing policy analysis and expectations for future growth.
