In 2027, what you pay out of pocket for drugs covered by your Medicare Part D plan is capped at $2,400 for the year, up from $2,100 in 2026. Once you reach the cap, you pay $0 for covered Part D drugs for the rest of the calendar year. No Part D plan can charge a yearly deductible above $700 in 2027, and some plans have no deductible at all. This guide explains how the cap works, how to track your spending, how to spread large costs across the year, and where to get help if your income is limited.

1. How the 2027 Out-of-Pocket Cap Works

The cap counts what you pay for drugs on your plan's list (formulary) during the calendar year, including your deductible and your copays or coinsurance. It also counts payments other people or programs make on your behalf, such as Medicare's Extra Help. Your monthly premium does not count toward the cap, and neither do drugs your plan does not cover.

Under the CMS standard benefit for 2027, the math works like this: you pay up to $700 during the deductible, then 25% of the cost of covered drugs. Once your total out-of-pocket spending reaches $2,400, the catastrophic stage begins and you pay nothing more for covered drugs until January 1. Your actual plan may use flat copays or a lower deductible instead of the standard 25% design, but the $2,400 cap applies to everyone with Medicare drug coverage.

2. The Three Coverage Stages

• Deductible stage: you pay the full negotiated price of covered drugs until you meet your plan deductible, if it has one. In 2027 no plan deductible can be higher than $700.
• Initial coverage stage: you pay copayments or coinsurance. In the standard benefit that is 25% of the drug cost.
• Catastrophic stage: once your out-of-pocket spending reaches $2,400, you pay $0 for covered Part D drugs for the rest of 2027.

There is no longer a "coverage gap" or "donut hole" stage. CMS removed it as part of the Part D redesign, and the 2027 standard benefit goes straight from initial coverage to the out-of-pocket threshold.

3. Spread Large Costs With the Medicare Prescription Payment Plan

If you expect big drug bills early in the year, the Medicare Prescription Payment Plan lets you pay your out-of-pocket costs in monthly installments instead of all at the pharmacy counter. Key points from Medicare.gov:

• Every Medicare drug plan offers it, and joining is voluntary and free.
• Instead of paying the pharmacy, you get a monthly bill from your plan. The bill is based on what you would have paid for your prescriptions plus any earlier balance, divided by the months left in the year.
• It can make monthly budgeting easier, but it does not lower your total drug costs. You still never pay more than the yearly cap for covered drugs.
• Because payments are spread over the months that remain, joining early in the year usually means smaller monthly bills than joining late in the year.

4. How to Track Your Spending

• Read your monthly Explanation of Benefits (EOB) from your plan. It shows which stage you are in and how much you have paid toward the $2,400 cap.
• Keep pharmacy receipts and a simple list of every prescription, dose and cost.
• Check your plan's online account or call the number on your plan card if a total looks wrong.
• If someone else or a program pays part of your costs, make sure it shows on your EOB, because those payments can count toward the cap.

Optional: a large-print weekly pill organizer and a simple medication log can help you keep doses and pharmacy costs straight during the year. You do not need any product to use Part D.

5. Ways to Lower Your Drug Costs

• Compare plans with your exact drug list. Use the Medicare Plan Finder and enter every drug, dose and your preferred pharmacy. Formularies, pharmacy networks and premiums change each year.
• Ask about generics or lower-tier drugs. Your doctor or pharmacist can tell you whether a covered alternative costs less.
• Use in-network and preferred pharmacies, and compare 30-day, 90-day and mail-order prices in your plan.
• Look at the whole year. A plan with a higher premium can still cost less overall if your drugs are expensive and you will hit the cap.
• Check outside discount programs for drugs your plan does not cover. See our prescription discount programs guide.

6. Extra Help If Your Income Is Limited

Extra Help is a Medicare program that helps people with limited income and resources pay Part D premiums, deductibles and copays. According to Medicare.gov, the 2026 limits for most states are:

Your situation	Income limit	Resource limit
Individual	$23,940	$18,090
Married couple	$32,460	$36,100

Limits are higher in Alaska and Hawaii, and Medicare notes they may go up each year. You get Extra Help automatically if you have full Medicaid coverage, get help paying Part B premiums from a Medicare Savings Program, or receive Supplemental Security Income (SSI). Otherwise, apply through Social Security at SSA.gov Extra Help. If you qualify, you keep Extra Help through December 31 even if your income changes mid-year.

Receiving SSI? See our SSI Benefits 2027 guide for payment amounts. Low-income adults under 65 may also want our Medicaid 2027 guide.

Frequently Asked Questions

Does my monthly premium count toward the $2,400 cap?

No. The cap counts deductibles, copays and coinsurance for covered drugs. Premiums and drugs your plan does not cover do not count.

Is the $2,400 cap the same in every Part D plan?

Yes. The 2027 out-of-pocket threshold applies to everyone with Medicare drug coverage, whether through a stand-alone Part D plan or a Medicare Advantage plan with drug coverage. Plans can have lower deductibles or different copays, but not a higher cap.

Will the Medicare Prescription Payment Plan save me money?

No. It spreads your out-of-pocket costs into monthly bills but does not lower them. If cost is the problem, check whether you qualify for Extra Help.
