Medicare Part D in 2027: The $2,400 Out-of-Pocket Cap and What Else to Know

If you take prescription drugs covered by Medicare, 2027 brings another step in the ongoing reshaping of Part D. The headline change is a higher annual out-of-pocket cap on covered drugs, along with updated program-level numbers that affect how plans are allowed to design their coverage. Here is a plain-English look at what is changing, what is staying the same, and what to watch for before coverage begins on January 1, 2027.

The $2,400 cap, in context

The biggest ongoing story in Part D is the annual limit on what you personally pay out of pocket for covered prescription drugs. That cap was $2,000 in 2025 and $2,100 in 2026. For 2027, it rises to $2,400.

Here is what the cap actually means. When your own spending on covered Part D drugs — things like deductibles, copays, and coinsurance at the pharmacy — adds up to $2,400 during the calendar year, you stop paying for those covered drugs for the rest of the year. The cap resets each January. Premiums do not count toward it, and drugs not on your plan's formulary do not count either. But for people who take expensive medications, hitting that ceiling can bring real relief compared with the pre-cap era, when there was no annual limit at all on what a person could spend.

What plans may charge in 2027

Two program-level numbers help frame what Part D plans may do in 2027:

• Maximum deductible: $700. A plan may set a deductible up to this amount, but many plans set theirs lower, and some set no deductible at all. The amount depends on the plan.
• Base beneficiary premium: $41.33. This is a program-wide reference figure used in setting Part D costs; it is not the premium you will pay. Actual plan premiums vary from plan to plan and from one area to another.

Because premiums, formularies, pharmacy networks, and cost sharing are set plan by plan, no one can tell you nationally what your plan will charge. That is why reviewing your own plan's materials matters.

The Annual Notice of Change

By September 30, 2026, every Part D plan and every Medicare Advantage plan with drug coverage must send its enrollees an Annual Notice of Change (ANOC). This document spells out what will be different in 2027: the premium, the deductible, the copays or coinsurance tiers, and — importantly — any changes to the drug list (formulary).

Read it. If a medication you take is moving to a higher tier, being removed, or getting new restrictions like prior authorization, you will want to know before January 1. The ANOC is the single best starting point for deciding whether to keep your current coverage or shop for something different.

Annual Enrollment: October 15 to December 7, 2026

Annual Enrollment is the window when anyone with Medicare can:

• Switch from Original Medicare to a Medicare Advantage plan, or vice versa.
• Change from one Medicare Advantage plan to another.
• Join, switch, or drop a stand-alone Part D drug plan.

Choices made during this window take effect January 1, 2027. If you do nothing, your current coverage generally continues into the new year with whatever changes the ANOC described.

If you are weighing Medicare Advantage against Original Medicare paired with a Medigap policy and a stand-alone Part D plan, both paths have trade-offs. Medicare Advantage often bundles drug coverage and may include extras, but typically uses provider networks and plan rules. Original Medicare with Medigap and Part D generally offers broader provider access and more predictable cost sharing, but usually at a higher combined premium. Neither path is "better" in the abstract; the right fit depends on your doctors, your medications, your budget, and how you prefer to use coverage.

The Medicare Prescription Payment Plan

The $2,400 cap limits your yearly total, but it does not change the fact that a big pharmacy bill can land in a single month. The Medicare Prescription Payment Plan — sometimes called "smoothing" — lets you pay your out-of-pocket drug costs in monthly installments spread across the year rather than all at once at the pharmacy counter.

Two things to understand clearly: it does not lower what you owe, and it is optional. For someone whose costs are modest or spread evenly, it may add paperwork without much benefit. For someone facing a large early-year prescription bill, it can smooth the cash-flow shock. You can opt in through your Part D plan.

What has not been announced yet

Several 2027 figures tied to Medicare more broadly — the standard Part B premium, the Part B deductible, and the income-related monthly adjustment (IRMAA) thresholds that affect higher-income beneficiaries — have not yet been set. CMS announces those in the fall. Be cautious about any source that quotes 2027 numbers for them before the official release.

To speak with someone by phone, call 1-800-MEDICARE (1-800-633-4227), available 24 hours a day, seven days a week. Reading your plan's Annual Notice of Change and comparing it against your current medications is a good first step before Annual Enrollment opens.
