What does it cost under Part D in 2027?

A negotiated price
Medicare negotiated a lower price for Enbrel, in effect from January 1, 2026: $2,355 for a 30-day supply, against a list price of $7,106 (2023). Where your share is a percentage of the drug's price, it is a percentage of the lower price; a flat copay stays as your plan sets it.
Your yearly cap in 2027
Out-of-pocket spending on covered Part D drugs stops at $2,400 in 2027 ($2,100 in 2026); after that, you pay nothing for covered drugs for the rest of the year.
The deductible
A plan's drug deductible is at most $700 in 2027 ($615 in 2026); many plans charge less or none.

Data, not medical advice. Coverage is the share of plan formularies listing the drug; your plan's formulary, tier and pharmacy decide what you pay.
