Medicaid managed care enrollment update – Q4 2022

This week, our In Focus section reviews recent Medicaid enrollment trends in capitated, risk-based managed care in 32 states.^[1] Many state Medicaid agencies post monthly enrollment figures by health plan for their Medicaid managed care population to their websites. This data allows for the timeliest analysis of enrollment trends across states and managed care organizations. All 32 states highlighted in this review have released monthly Medicaid managed care enrollment data into the fourth quarter (Q4) of 2022. This report reflects the most recent data posted. HMA will continue tracking enrollment throughout the eligibility redetermination period. HMA has made the following observations related to the enrollment data shown on Table 1 (below):

• The 32 states in this report account for an estimated 71 million Medicaid managed care enrollees as of December 2022. Based on HMA estimates of MCO enrollment in states not covered in this report, we believe that nationwide Medicaid MCO enrollment was likely about 75 million in December 2022. As such, the enrollment data across these 32 states represents approximately 95 percent of all Medicaid MCO enrollment.
• Across the 32 states tracked in this report, Medicaid managed care enrollment is up 7.5 percent year-over-year as of December 2022.
• All states, besides Mississippi, saw increases in enrollment in December 2022, compared to the previous year, due to the gains from the COVID-19 pandemic. Mississippi Medicaid managed care enrollment fell because the state shifted members to FFS during the public health emergency.
• Twenty-three of the 32 states – Arizona, California, District of Columbia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Jersey, New Mexico, New York, Ohio, Oregon, Pennsylvania, Virginia, Washington, and West Virginia – expanded Medicaid under the Affordable Care Act and have seen increased Medicaid managed care enrollment since expansion.
• The 23 expansion states listed above have seen net Medicaid managed care enrollment increase by 3.5 million members, or 7.2 percent, in the past year, to 52.2 million members at the end of 2022.
• The nine states that have not yet expanded Medicaid as of December 2022 – Florida, Georgia, Kansas, Mississippi, North Carolina, South Carolina, Tennessee, Texas, and Wisconsin – have seen Medicaid managed care enrollment increase 8.3 percent to 19 million members at the end of 2022.

Table 1 – Monthly MCO Enrollment by State – July 2022 through December 2022

Note: In Table 1 above and the state tables below, “+/- m/m” refers to the enrollment change from the previous month. “% y/y” refers to the percentage change in enrollment from the same month in the previous year.

Below, we provide a state-specific analysis of recent enrollment trends in the states where HMA tracks data.

It is important to note the limitations of the data presented. First, not all states report the data at the same time during the month. Some of these figures reflect beginning-of-the-month totals, while others reflect an end-of-the-month snapshot. Second, in some cases the data is comprehensive in that it covers all state-sponsored health programs for which the state offers managed care; in other cases, the data reflects only a subset of the broader Medicaid managed care population. This is the key limiting factor in comparing the data described below and figures reported by publicly traded Medicaid MCOs. Consequently, the data we review in Table 1 and throughout the In Focus section should be viewed as a sampling of enrollment trends across these states rather than a comprehensive comparison, which cannot be developed based on publicly available monthly enrollment data.
