By the Numbers

As of 2021, more than 42% of the eligible Medicare population (27 million+ older Americans and individuals with disabilities) have made the choice to enroll in a Medicare Advantage plan.  Use the interactive maps below for a closer look at the Medicare population in your state or district.

About Medicare Advantage

For over 20 years, the Medicare Advantage (MA) program has been integral to the Medicare guarantee, offering choices and meeting the comprehensive healthcare needs of American seniors. Under this public-private partnership, plans must cover the same services as fee-for-service Medicare. The savings generated through care coordination are reinvested into lowering beneficiaries’ premiums and out-of-pocket costs and providing supplemental benefits such as dental, vision, hearing, meals, and transportation.

Budget Cut Impact

The following map displays the potential impact of various proposed policy scenarios on Medicare Advantage beneficiaries. Use the ‘Policy Scenario’ filter to understand how a specific policy proposal could directly impact a selected state or district.

Policy Scenario

Would increase the Centers for Medicare & Medicaid Services (CMS) coding intensity adjustment from the statutory minimum of 5.9% to 7.0%. Federal law currently requires CMS to apply an across-the-board reduction to Medicare Advantage (MA) plan payments that is intended to reflect the difference in coding intensity between MA and Traditional Medicare. The adjustment is applied as a reduction to MA risk scores and reduces plan payment.

Certain counties with both low fee-for-service spending and historically high Medicare Advantage enrollment are designated as "double bonus counties." The quality bonuses applied to benchmarks in those counties are twice as high as in other counties. This policy would lower Stars quality bonus payments for qualifying plans in those counties from 10% to 5%. Qualifying plans are those that have composite quality scores with at least 4 out of 5 stars.

Would reduce Medicare Advantage (MA) benchmarks 2% across-the-board. Applies an across-the-board cut to the existing MA benchmarks.

Would remove the quartile adjustment to county fee-for-service (FFS) rates and instead use an average of the county and national FFS spend as recommended by MedPAC. Currently, the Centers for Medicare & Medicaid Services establishes county-level benchmarks and assigns those benchmarks quartile categories based on relative levels of spend. This quartile system is intended to increase the benchmarks in areas with historically low FFS costs and to achieve savings from areas with high FFS costs. For example, county benchmarks are 95%, 100%, 107.5% or 115% of projected county FFS costs, with the 25% of counties with the highest FFS costs assigned the lowest percentage (95%) and the 25% of counties with lowest FFS costs assigned the highest percentage (115%).

In their June 2021 Report to Congress, MedPAC included a number of Medicare Advantage benchmark policy recommendations. The Commission’s recommendations are as follows:

  • Eliminate the quartile adjustment and replace with blended local/national benchmark
  • Calculate benchmarks for Part A and Part B fee-for-service (FFS) population
  • Eliminate benchmark cap
  • Reduce benchmarks 2% across-the-board
  • Use geographic markets (not county) to calculate the benchmarks
  • Apply 75% rebate percentage
