Medicare Advantage Plans have become an increasingly popular alternative to Original Medicare. These private Medicare Plans administered by health insurers provide all Medicare Part A and Part B benefits. Medicare Advantage enrollment has been steadily growing for many years. But exactly what percentage of Medicare beneficiaries are choosing Medicare Advantage Plans over traditional Medicare?

Understanding current Medicare Advantage enrollment statistics and trends can provide helpful insight into how extensively this option has been adopted among seniors. In this article, we’ll break down the latest data on the percentage of the Medicare population enrolled in Medicare Advantage.

Medicare Advantage Plan Growth

This dramatic expansion demonstrates Medicare Advantage health plan is becoming a coverage pillar for many Medicare recipients. Next we’ll look at current enrollment percentages.

  • This would represent over 47 million members enrolled
  • For comparison, 2022 membership was just under 29 million

  • 26% are enrolled in local PPO plans
  • 10% have regional PPO coverage
  • 2% are in private fee-for-service plans

HMO plans remain the most popular Medicare Advantage option due to their low costs and extensive provider networks in many areas.

Demographic Differences in Enrollment

Certain demographics are more likely than others to enroll in Medicare Advantage:

  • 44% of Medicare males vs. 40% of females have Medicare Advantage
  • 49% of Hispanics compared to 41% of whites
  • 57% of enrollees earning less than $10k annually
