Medicare Advantage Enrollment Update 2022

This policy brief continues the RUPRI Center's annual series of Medicare Advantage (MA) enrollment updates. In addition to tracking overall and nonmetropolitan/metropolitan enrollment, this brief also reports on changes in enrollment in types of MA plans. The Center's ongoing line of inquiry also considers policy changes from previous years that may have impacted MA plan enrollment.

Key Findings:

• Overall MA enrollment grew by 8.7 percent (2.3 million) from 2021 to 2022; the rate of growth was higher in nonmetropolitan counties (13.4 percent) than in metropolitan counties (7.9 percent).
• Overall, more than half of MA enrollees (57.9 percent) were in Health Maintenance Organization (HMO) plans. The largest proportion of nonmetropolitan enrollees (51.5 percent) were in Local Preferred Provider Organization (PPO) plans, whereas the largest proportion of metropolitan enrollees (61.4 percent) were in HMO plans.
• The percentage of nonmetropolitan MA enrollees in HMO plans increased from 36.8 percent in 2021 to 37.8 percent in 2022. However, there was a decrease in metropolitan enrollees in HMO plans (63.0 percent in 2021 to 61.4 percent in 2022).
• Enrollment in Local PPO plans increased in both nonmetropolitan (from 48.9 percent to 51.5 percent) and metropolitan counties (from 33.2 percent to 35.6 percent) between 2021 and 2022.
