The $2,400 Part D Cap in 2027: What It Actually Saves You

For some people this number is the most important one in Medicare. For others it is a line they will never reach. Worth knowing which you are.

The short answer

In 2027 there is a hard ceiling of $2,400 on what you pay out of pocket for covered prescriptions in a calendar year, up from $2,100 in 2026. Hit it and you pay nothing more for covered drugs until January. Your deductible payments count toward it. Your monthly premium does not, and neither does anything spent on a drug your plan does not cover at all.

Before 2025 there was no ceiling at all on Part D spending. Someone on an expensive specialty drug could pay thousands of dollars a year, every year, with no point at which it stopped. The cap changed that, and it is the single most consequential thing to happen to Medicare drug coverage in a long time — for the people it applies to.

How the year actually goes

Three phases, in order. The numbers below are Medicare’s program-wide figures, not any particular plan’s.

01
You pay the deductible
Up to $700 in 2027, if your plan charges the full standard amount. Many charge less or none, and some apply it only to certain drug tiers. During this stretch you are paying the plan's price for your medication.
02
You share the cost
Once the deductible is met, you pay copays or coinsurance and the plan pays the rest. How much depends on which tier your specific drug sits on, which is why two people with identical plans can have very different years.
03
You reach $2,400 and stop
Add up everything from phases one and two. When your own spending on covered drugs reaches $2,400, you are done paying for covered prescriptions for the rest of the calendar year.

The word doing the heavy lifting is “covered”

The cap applies to covered prescriptions. If a medication is not on your plan’s drug list, what you spend on it does not count toward the $2,400, and the cap will never protect you from it. You could spend well past $2,400 on an uncovered drug and still be paying full price in December.

This is why comparing plans on the cap alone is a mistake. The cap is identical everywhere — it is set by Medicare, not by the plan. What differs between plans is which of your drugs are covered and on what tier, and that is what decides your actual year.

Two people, same plan, very different years

Someone taking three low-cost generics may spend a couple of hundred dollars across the whole year and never come near the ceiling. For them the cap is insurance against a bad year they have not had yet — real value, but invisible.

Someone on a single specialty medication can reach $2,400 inside the first few months and then pay nothing for the remaining three-quarters of the year. Same plan, same rules, completely different experience. Which one you are depends entirely on your own prescriptions.

Why the deductible increase matters here

The standard deductible rises to $700 in 2027 while the cap rises to $2,400. More of your spending happens before the plan starts sharing costs, which front-loads the year. If you are someone who reaches the cap anyway, the practical effect is mostly about timing. If you are not, the deductible is a larger share of what you will actually pay, and tier placement matters more than ever. More on the $700 deductible here.

What to do with this

Write down every prescription you take, with the dosage. Then the question to ask about any plan is not “what is the cap” — it is the same everywhere — but “are all of my drugs covered, and on which tiers.”

If you want to change plans, Annual Enrollment runs October 15 – December 7, 2026, and coverage starts January 1, 2027. Specific 2027 plan details become available on October 1, 2026.

Bring the list, not the questions

A drug list review takes about twenty minutes and tells you what your medications will actually cost. No cost to you, and no obligation to change anything.

Out-of-pocket cap questions, answered

What is the Medicare Part D out-of-pocket cap for 2027?+

It is $2,400, up from $2,100 in 2026. Once what you have paid for covered prescriptions reaches $2,400 in a calendar year, you pay nothing more for covered drugs for the rest of that year. The figure comes from the CMS Contract Year 2027 Rate Announcement released April 6, 2026.

Does the deductible count toward the cap?+

Yes. What you pay toward your Part D deductible counts toward the $2,400 cap, as does what you pay in copays and coinsurance afterward. None of it is wasted or counted twice.

What does not count toward the cap?+

Your monthly plan premium does not count. Neither does anything you spend on a drug your plan does not cover, which is the part that catches people out. If a medication is off your plan's drug list entirely, paying for it yourself does not move you toward the cap at all.

Who actually reaches the $2,400 cap?+

Mostly people taking brand-name or specialty medications. Someone on a handful of low-cost generics may never come close in a year, and for them the cap is insurance against a bad year rather than something they will use. Someone on an expensive specialty drug can reach it within the first few months.

Does the cap reset?+

Yes, every January 1, along with the deductible. That is why prescription costs tend to feel worst early in the year and ease off later.

Can I spread these costs over the year instead of paying them up front?+

Medicare offers a payment option that lets you spread what you owe for covered prescriptions across monthly payments rather than paying the full amount at the pharmacy counter. It does not reduce what you owe in total, it changes the timing. Whether it helps depends on your situation, so it is worth asking about specifically rather than assuming.
