- Starting Jan. 1, 2027, Medicare Part D caps yearly out-of-pocket costs for covered drugs at $2,400, and once you hit that amount, you pay nothing more for the rest of the year on covered drugs.
- The old "donut hole" coverage gap is gone, phased out in 2025, leaving Part D with three simpler stages: deductible, initial coverage, and catastrophic coverage.
- A free, optional Medicare Prescription Payment Plan lets you spread your out-of-pocket drug costs into monthly installments across the year instead of paying it all at the pharmacy.
- The $2,100 cap and payment plan apply to every Part D plan by law, but coverage details like which drugs, pharmacies, and pre-cap costs are involved still vary by plan, and those with income above $109,000 (single filer) in 2026 may owe an extra IRMAA charge.
Here's a plain-language look at what's new, what stayed, and what to do during this fall's Annual Enrollment Period.
The Part D cap, explained
Under the 2027 Part D rules from the Centers for Medicare & Medicaid Services (CMS), once your out-of-pocket spending on covered drugs hits $2,400, you owe nothing more for the rest of the calendar year on those covered drugs. The cap resets each January.
A few things to keep in mind:
- The cap counts what you pay for covered Part D drugs — deductibles, copays, and coinsurance.
- Monthly premiums do not count toward the cap.
- Drugs your plan doesn't cover don't count either. That's why checking a plan's formulary matters.
- The Part D deductible can be no higher than $700 in 2027, though many plans set it lower.
The coverage gap is gone
If you've had Medicare for a while, you probably remember the "donut hole" — that middle stretch where your share of drug costs jumped. It was phased out in 2025.
Part D now has three simpler stages: the deductible, the initial coverage phase, and catastrophic coverage (where you pay nothing once you hit the annual cap). No more falling into a gap mid-year.
The Medicare Prescription Payment Plan
Even with a $2,100 in 2026 ($2,400 in 2027) ceiling, hitting a big pharmacy bill in January can sting. That's where the Medicare Prescription Payment Plan comes in.
It's a free, optional program that lets you spread your out-of-pocket drug costs across the calendar year in monthly installments, instead of paying at the pharmacy counter. You don't pay more overall — you pay the same total, just smoothed out.
Some points worth knowing:
- You sign up through your Part D or Medicare Advantage drug plan, not through Medicare directly.
- It generally helps most if you have high drug costs early in the year or take an expensive specialty medication.
- If your prescriptions are inexpensive, it may not make a meaningful difference.
- You can opt in any time, but signing up before or early in the year usually gives you the biggest smoothing benefit.
What this means locally
Little Elm sits in Denton County, where Medicare eligibles have a range of stand-alone Part D plans and Medicare Advantage plans that include drug coverage. Plan availability, formularies, and pharmacy networks are set at the county level, so your options are the same as the rest of Denton County — not city-specific.
Because the cap ($2,100 in 2026, $2,400 in 2027) and payment plan apply across all Part D plans, no single plan is "unlocking" this benefit. It's the law. What still varies plan to plan is which drugs are covered, which pharmacies are in-network, and what you pay before you hit the cap.
Key dates for this season
- Annual Enrollment Period (AEP): October 15 – December 7, 2026. This is when you can join, switch, or drop a Part D or Medicare Advantage plan for 2027.
- Medicare Advantage Open Enrollment: January 1 – March 31. If you're already in a Medicare Advantage plan, you get one chance to switch to another Advantage plan or return to Original Medicare with a Part D plan.
If your income is above $109,000 (single filer) in 2026, you may also owe an income-related monthly adjustment amount (IRMAA) on top of your Part D premium.

How Medicare Part D works in 2027
The old coverage gap (“donut hole”) was eliminated as of 2025 (three phases now). The yearly cap on what you pay out of pocket for covered drugs is $2,100 in 2026 and $2,400 in 2027, and you can spread those costs across the year with the Medicare Prescription Payment Plan.
