This week, our In Focus section reviews recent Medicaid enrollment trends in capitated, risk-based managed care in 30 states.1 Many state Medicaid agencies post monthly enrollment figures by health plan for their Medicaid managed care population on their websites. These data allow for timely analysis of enrollment trends across states and managed care organizations. All 30 states highlighted in this review have released monthly Medicaid managed care enrollment data into quarter four (Q4) of 2023. The analysis that follows reflects the most recent data posted. HMA continues tracking enrollment as states work towards concluding their Public Health Emergency (PHE) unwinding-related redeterminations and resuming normal eligibility operations.
Health Management Associates, Inc., (HMA) has reviewed the Q4 enrollment data (see Table 1) and offers the following observations:
- Across the 30 states tracked in this report, Medicaid managed care enrollment declined by 7.3 percent year-over-year as of December 2023.
- Of the 30 states, 26 experienced decreased enrollment in December 2023, compared with the previous year, as the result of Medicaid redeterminations.
- A total of 23 of the states—Arizona, California, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, Nebraska, Nevada, New Jersey, New Mexico, New York, North Carolina, Ohio, Oregon, Pennsylvania, Virginia, Washington, and West Virginia—saw net Medicaid managed care enrollment decrease by 469,000 (0.9%) to 51.5 million members at the end of Q4 2023. (Note: North Carolina expanded Medicaid in December 2023 and was added to the expansion group, in part inflating the change).
- The seven states that had yet to expand Medicaid as of December 2022—Florida, Georgia, Mississippi, South Carolina, Tennessee, Texas, and Wisconsin—have seen Medicaid managed care enrollment decrease 25.2 percent to 13.9 million members at the end of Q4 2023.

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, whereas others provide an end of the month snapshot. Second, in some cases the data are comprehensive in that they cover all state-sponsored health programs offering managed care; in other cases, the data reflect only a subset of the broader managed Medicaid population, making it the key limitation to comparing the data described below and figures that publicly traded Medicaid MCOs report. Consequently, the data in Table 1 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 information.
