How much of your own money can a prescription cost you in a single year? Until 2025 the honest answer was that it depended on how sick you got.
Then the ceiling arrived. Part D out of pocket spending was capped at $2,000 that year, and the old coverage gap went away with it.
The cap is indexed, so it climbs. It went to $2,100 this year. CMS has set it at $2,400 for 2027.
At the same time the drugs themselves got cheaper, and that part is not small.
Ten high-spend medicines got negotiated prices effective the first of January this year. Eliquis, Jardiance, Xarelto, Januvia, Farxiga, Entresto and four more. The negotiated prices run 38 to 79 percent below the old list prices.
Fifteen more were settled in November and start January 1, 2027. That list includes semaglutide, priced at $274 for a thirty day supply. Real money, for real people.

The shape of next year shows up.
The deductible you pay before coverage starts goes up. The base premium goes up. And the program that has been holding premium increases down expires with this year, which CMS confirmed in July.
So who actually banks the negotiated savings?
CMS puts the first year at roughly $6 billion net for the program. The out of pocket share is about $1.5 billion. It spreads across the 9 million enrollees who take one of those ten drugs. There are 54 million people in Part D. Do that division.
Which means most enrollees meet the new ceiling and the higher deductible without ever touching a negotiated price.
Where the cohort’s money sits this quarter, and the bill that gets reset every January.
The honest limit is that the cap is a genuine win, and it is aimed at the people who need it most.
Anybody on a high-cost specialty drug now has a worst case they can name. That used to be the frightening part of a diagnosis, and it is gone. That matters.
Somebody funds it, though, and that is the premium line for all 54 million. A ceiling that protects the sickest is paid for monthly by everyone standing under it.
The arithmetic
Centers for Medicare and Medicaid Services Part D parameters: an out of pocket cap of $2,000 in 2025, $2,100 in 2026 and $2,400 in 2027, with the maximum deductible rising from $615 in 2026 to $700 in 2027, and the base beneficiary premium going from $38.99 to $41.33. CMS announced in July 2026 that the Part D premium stabilization demonstration ends after this year. Medicare Drug Price Negotiation Program: negotiated prices for the first ten drugs took effect January 1, 2026 at 38 to 79 percent below list, with CMS estimating about $6 billion in net program savings in the first year and roughly $1.5 billion in out of pocket savings for about 9 million of the 54 million Part D enrollees. CMS announced negotiated prices for the second cycle of 15 drugs on November 25, 2025, effective January 1, 2027, including semaglutide at $274 for a thirty day supply, with projected out of pocket savings of $685 million. The annual enrollment window runs October 15 to December 7.
Your plan mails an annual notice of change in September. It is dull, it is thin, and it holds next year’s deductible and the tier your own prescriptions land in. Read that before the window opens on October 15, because the window is when it can be fixed. Nothing about your medicine has changed this week. The price of standing still has.
