Medicare Part D Changes Coming in 2027: Medicare Part D is set for another important update in 2027. These changes are mainly linked to the Inflation Reduction Act (IRA), which has been changing how prescription drug costs work for people with Medicare.
For seniors, the biggest things to watch are the higher annual deductible and the higher out-of-pocket spending limit. There are also new Medicare-negotiated prices for 15 prescription drugs, which could lower costs for people who use those medicines.
The changes will start on January 1, 2027. CMS has already released the final 2027 Part D benefit amounts.

Medicare Part D Costs Will Change in 2027
The standard Medicare Part D benefit will have a $700 deductible in 2027. This means a person with a standard Part D benefit may have to pay the first $700 of covered prescription drug costs before the plan starts paying its share.
The annual out-of-pocket threshold will also rise from $2,100 in 2026 to $2,400 in 2027. Once a person reaches this amount in out-of-pocket spending on covered Part D drugs, they won’t have to pay additional cost sharing for covered Part D drugs for the rest of the year.
| Part D Benefit | 2026 | 2027 |
|---|---|---|
| Standard deductible | $615 | $700 |
| Out-of-pocket threshold | $2,100 | $2,400 |
The increase doesn’t mean every senior will pay exactly these amounts. Actual costs can be different because Part D plans set their own premiums, formularies, copays and other cost-sharing rules.
Another important point is that the old coverage gap, often called the “donut hole,” is no longer part of the standard Part D benefit. The redesigned benefit has three main stages: the deductible, initial coverage and catastrophic coverage. After the out-of-pocket limit is reached, there is no cost sharing for covered Part D drugs during the catastrophic phase.

15 More Drugs Will Get Medicare-Negotiated Prices
One of the biggest changes for 2027 is the next round of Medicare drug price negotiations. CMS has negotiated prices for 15 high-cost drugs covered by Medicare Part D. These negotiated Maximum Fair Prices will take effect on January 1, 2027. The drugs are used for conditions including diabetes, cancer, asthma and other serious health problems. The 15 drugs are:
- Austedo and Austedo XR
- Breo Ellipta
- Calquence
- Ibrance
- Janumet and Janumet XR
- Linzess
- Ofev
- Otezla and Otezla XR
- Ozempic, Rybelsus and Wegovy
- Pomalyst
- Tradjenta
- Trelegy Ellipta
- Vraylar
- Xifaxan
- Xtandi
This is separate from the first 10 negotiated drugs whose new prices began in 2026. That means a total of 25 negotiated drugs will have Medicare-negotiated prices in effect by 2027.

The lower prices won’t mean every person automatically gets the same savings. What a senior actually pays will still depend on the person’s Part D plan and coverage. However, the negotiated prices can reduce the amount Medicare and beneficiaries spend on these selected medicines.
What Seniors Should Check Before 2027
Part D plans can change their premiums, drug lists, pharmacies and cost-sharing rules every year. So seniors shouldn’t simply keep the same plan without checking the new 2027 details.
CMS says the 2027 national base beneficiary premium, which is used in calculating plan premiums, will be $41.33. The national average monthly bid amount will be $296.05. The base beneficiary premium isn’t the exact premium every person will pay because actual premiums depend on the plan and other factors.
Seniors should especially check whether their regular medicines are still covered and how much they will cost in 2027. They should also look at whether their preferred pharmacy is still in the plan’s network.
Medicare’s Open Enrollment period runs from October 15 through December 7 each year. Changes made during this period generally take effect January 1 of the next year. This is the main time to compare 2027 Part D plans and switch plans when another option works better. People with high prescription costs can also use the Medicare Prescription Payment Plan. It spreads covered Part D out-of-pocket costs across the year, but it doesn’t reduce the total amount a person owes.
For many seniors, the most important 2027 numbers are therefore easy to remember: a $700 standard deductible, a $2,400 annual out-of-pocket threshold and 15 more drugs with negotiated Medicare prices.
