2027 Medicare Plan Change Notices Are Landing in Mailboxes Now, With Two Key Part D Cost Thresholds Rising
Members should expect their Annual Notice of Change by September 30, and two drug-benefit benchmarks inside those letters are higher for 2027: the standard deductible ceiling rises to 700 dollars and the annual out-of-pocket spending cap rises to 2,400 dollars.

Medicare Advantage and standalone prescription drug plan members should be receiving their Annual Notice of Change this week. Plans are required to deliver the notice by September 30. The letter specifies every change to premiums, deductibles, copays, covered drugs, and provider networks scheduled to take effect January 1, 2027.
Two cost thresholds in the Part D prescription drug benefit are higher for 2027. The ceiling on the standard deductible a Medicare drug plan may charge rises to 700 dollars, up from 615 dollars in 2026. The annual out-of-pocket spending cap for covered drugs rises to 2,400 dollars, up from 2,100 dollars in 2026. Once a member's spending reaches the cap, the plan covers the full cost of covered drugs for the rest of the year.
Your 2027 Medicare plan change letter is due by September 30. Two numbers to watch: the Part D deductible ceiling rises to 700 dollars and the out-of-pocket cap rises to 2,400 dollars.
Not every plan charges the maximum deductible, and not every plan will show a premium increase. The notice reflects each member's specific current plan and lists only that plan's changes. Members should read the letter carefully and compare it against competing plans before deciding whether to stay or switch.
Beyond cost-sharing figures, the letters may also reflect formulary changes, pharmacy network adjustments, and updated rules for accessing specific medications.
Annual enrollment, the period when most members can join, switch, or drop a Medicare Advantage plan or drug plan, runs October 15 through December 7, 2026. Members who have not received their notice by October 1 are advised to contact their plan directly to request one.
In plain words
If you have a Medicare drug plan or a Medicare Advantage plan, a letter should arrive in your mailbox soon. It must be sent to you by September 30. The letter shows every change your plan is making for 2027. Two drug cost limits are going up. The highest deductible a plan can charge rises to 700 dollars. The most you can pay out of pocket for covered drugs in a year rises to 2,400 dollars. Once you reach that limit, you pay nothing more for covered drugs for the rest of that year. Read your letter carefully. Not every plan charges the highest amount. Compare your options before enrollment closes on December 7.
