A review of the 2025 Medicare Advantage plans available for individual enrollment shows that the total number of plans declined by 7% (from 3,959 to 3,699). The average Medicare beneficiary will have the option of 34 Medicare Advantage prescription drug (MA-PD) plans in 2025, just 2 fewer than the 36 options available in 2024. Since 2018, the number of plans available to the average beneficiary has doubled.
Nearly 50 million prior authorization requests were submitted to Medicare Advantage insurers on behalf of Medicare Advantage enrollees in 2023, of which 3.2 million (6.4%) were denied. Just 11.7% of denied requests were appealed, though 81.7% of appeals overturned the initial denial in Medicare Advantage. Substantially fewer prior authorization requests were made in traditional Medicare, reflecting the small number of services subject to prior authorization requirements.
This analysis looks at traditional Medicare spending among people who choose to disenroll from Medicare Advantage and obtain coverage under traditional Medicare during the annual Medicare open enrollment period. It compares their traditional Medicare spending (Parts A and B) in the year following disenrollment to similar people who were continuously covered by traditional Medicare, using data from the Medicare Beneficiary Summary File (MBSF) for 2021 and 2022.
People who are dually eligible for both Medicare and Medicaid coverage can get their Medicare coverage in a variety of ways. The brief breaks out the data for traditional Medicare, Medicare Advantage plans that are available to all Medicare beneficiaries, and plans that are designed specifically for dual-eligible beneficiaries.
Using health insurer financial data for 2023, we find that in 2023, per enrollee gross margins were highest in the Medicare Advantage market, and medical loss ratios were lowest in the individual insurance market. Across most markets, gross margins have been relatively stable in recent years.
In 2024, more than half (54%) of eligible Medicare beneficiaries are enrolled in Medicare Advantage plans. This brief provides current information about Medicare Advantage enrollment, by plan type and firm, and shows how enrollment varies by state and county.
This issue brief merged beneficiary-level Medicare and Medicaid data from 2021 to document sources of coverage for dual-eligible individuals nationwide and by state.
This brief analyzes 2024 Medicare Part D enrollment, premiums, and cost sharing. The analysis highlights the continued growth in Medicare Advantage enrollment in the Part D marketplace and substantially higher average monthly premiums for stand-alone Part D drug plan coverage. Changes to the Part D benefit included in the Inflation Reduction Act are helping to lower out-of-pocket costs for patients but could also contribute to higher-priced Part D coverage.
This analysis examines the extent to which states are providing health benefits to their Medicare-eligible retirees through Medicare Advantage arrangements. In 2024, a majority of states offer Medicare Advantage plans to their state retirees, with 13 offering Medicare Advantage exclusively.
For 2024, the average Medicare beneficiary has access to 43 Medicare Advantage plans and can choose from plans offered by 8 firms. Among the majority of Medicare Advantage plans that cover prescription drugs, 66 percent will charge no premium in addition to the monthly Medicare Part B premium. As in previous years, the vast majority of Medicare Advantage plans will offer supplemental benefits, including fitness, dental, vision, and hearing benefits.
