The MHA recently updated its analysis of Medicaid and Medicare enrollment based on February 2025 data. The analysis includes program enrollment as a percentage of each county’s total population and the split between fee-for-service and managed care organization. Just over 27% of Michigan’s total population is enrolled in Medicaid and 23% is enrolled in Medicare.
Roughly two-thirds of Michigan’s 2.66 million Medicaid beneficiaries are enrolled in one of nine managed care plans.
Total Medicare enrollment is 2.26 million with 63% of beneficiaries enrolled in a Medicaid Advantage (MA) plan with only two counties having less than 50% of total Medicare enrollment in MA plans. MA enrollment by county ranges from 46% to 78%, with 72 counties having 55% or more of their Medicare population enrolled in an MA plan.
February enrollment is spread across 47 MA plans with up to 26 plans covering beneficiaries in several Michigan counties, with a minimum of six plans available in each county.
Members with enrollment questions should contact the Health Finance team at the MHA.
