- Starting Jan. 1, 2027, Medicare Part D out-of-pocket drug costs are capped at $2,400 per year, up from the $2,100 limit in 2026, and once you hit that amount your covered drugs cost $0 for the rest of the year.
- Part D has just three phases—deductible (no more than $700 in 2027), initial coverage, and catastrophic—since the old four-phase system with the mid-year "donut hole" gap ended in 2025.
- The optional, free Medicare Prescription Payment Plan (M3P) lets you spread your out-of-pocket drug costs into monthly payments instead of paying it all at the pharmacy at once.
- These federal rules, including the $2,100 cap and $615 deductible limit, apply to every stand-alone Part D and Medicare Advantage drug plan, though formularies, pharmacy networks, and premiums still vary by plan, and higher earners (single filers above $109,000 in 2026) may still owe an IRMAA surcharge, which can be reconsidered if income has dropped.

Sulphur, La. — A big change hits your pharmacy counter in 2027
Starting Jan. 1, 2027, no one with a Medicare Part D drug plan will pay more than $2,400 out of pocket for covered prescriptions in a calendar year. Once you hit that ceiling, your covered drugs cost you $0 for the rest of the year. For people in Sulphur who take pricey medications — think brand-name insulin regimens, cancer pills, or specialty drugs for autoimmune conditions — this continues the most meaningful shift in Part D in years.
The cap moves up from the $2,100 limit set for 2026, and it applies whether your drug coverage comes through a stand-alone Part D plan or a Medicare Advantage plan that includes drugs.
The "donut hole" is gone — here's what replaced it
For years, Part D had four confusing phases, including the dreaded coverage gap where costs jumped mid-year. That's over.
As of 2025, Part D has just three phases, and the same structure continues in 2027:
1. Deductible phase — you pay full negotiated price until you meet your plan's deductible (no more than $700 in 2027; some plans set it lower or waive it). 2. Initial coverage phase — you pay a copay or coinsurance for each prescription until your out-of-pocket spending hits $2,400. 3. Catastrophic phase — you pay $0 for covered drugs the rest of the year.
There's no more "you're doing fine, then suddenly you're not" surprise in the middle of the year. Once the meter hits $2,400, you're done paying for covered drugs until January.
The Medicare Prescription Payment Plan: spreading costs over the year
Hitting a $2,400 cap sounds great in December — but what if a big bill lands in January? That's where the Medicare Prescription Payment Plan comes in. It's a free, optional program (sometimes called "M3P") that lets you spread your out-of-pocket drug costs across monthly payments instead of paying the pharmacy all at once.
A few things to know:
- You still owe the same total amount — the payment plan doesn't lower your costs; it just smooths them out.
- You sign up through your Part D or Medicare Advantage drug plan, not at the pharmacy.
- It tends to help most if you have a large drug expense early in the year.
- You can join anytime during the year, though enrolling before you fill a big prescription makes the math work best.
If you're not sure whether this option fits your situation, call your plan or 1-800-MEDICARE.
What this looks like in Sulphur
Sulphur is in Calcasieu Parish, where a range of stand-alone Part D plans and Medicare Advantage plans with drug coverage are offered each year. The $2,400 cap, the $700 maximum deductible, and the payment plan apply to all of them in 2027 — those are federal Part D rules, not plan-by-plan features. For the 2027 lineup, check each plan's ANOC and Medicare.gov's Plan Finder.
Plan-specific details like formularies (which drugs are covered), pharmacy networks, and premiums vary. Before you decide anything for 2027, check that your medications are on a plan's formulary and that your usual pharmacy — whether that's a chain on Ruth Street or an independent nearby — is in-network.
Higher-income filers: IRMAA still applies
If your income is above certain thresholds, you'll pay an Income-Related Monthly Adjustment Amount (IRMAA) on top of your Part D premium. For 2026, IRMAA kicks in for single filers with income above $109,000 (and married couples filing jointly at higher thresholds). Social Security uses your tax return from two years earlier to decide. If your income has dropped since then — retirement, loss of a spouse, reduced hours — you can ask for a reconsideration.
Key dates to remember
- Oct. 15 – Dec. 7, 2026: Medicare Annual Enrollment Period. This is when you can join, switch, or drop a Part D or Medicare Advantage plan for 2027.
- Jan. 1, 2027: New coverage begins. The $2,400 cap starts fresh.

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