Medicare Advantage in 2025: Enrollment Update and Key Trends

In 2025, more than half (54%) of eligible Medicare beneficiaries - 34.1 million out of about 62.8 million with both Medicare Parts A and B - are enrolled in Medicare Advantage plans. The Congressional Budget Office projects that the share will rise to 64% by 2034.

One in five (21%) Medicare Advantage enrollees is in a special needs plan (SNP), reflecting a steady increase in recent years. Overall, Medicare Advantage enrollment is highly concentrated among plans owned by a few firms.

The Effect of Delaying the Selection of Small Molecule Drugs for Medicare Drug Price Negotiation

Part of a recent executive order from President Trump directs the Secretary of HHS to work with Congress to implement a change in the Medicare Drug Price Negotiation Program to delay negotiation of so-called “small molecule” drugs beyond 7 years after FDA approval under current law. If that timeframe had already been in place, more than half of the Part D drugs that were selected for price negotiation in the first or second rounds – 13 out of 25 – would not have been eligible at the time drugs were selected.
