This brief provides an overview of premiums and benefits in Medicare Advantage plans that are available for 2025 and key trends over time. Two-thirds of all Medicare Advantage plans with Part D prescription drug coverage (MA-PDs) (67%) will charge no premium (other than the Part B premium) in 2025, similar to 2024 (66%). Nearly all Medicare Advantage plans (97% or more) are offering vision, dental and hearing, as they have in previous years. However, the share of plans offering certain benefits has declined, such as over-the-counter benefits (85% in 2024 vs. 72% in 2025), remote access technologies (74% in 2024 vs. 53% in 2025), meal benefits (72% in 2024 vs. 65% in 2025) and transportation (36% in 2024 vs. 29% in 2025).
