Key takeaways
- Starting Jan. 1, 2027, the Medicare Part D yearly cap on out-of-pocket drug costs is $2,400, and once you hit it, covered drugs cost nothing for the rest of the year.
- The old "donut hole" coverage gap is gone, leaving just three simple phases: deductible (up to $700 in 2027), initial coverage, and catastrophic coverage.
- The Medicare Prescription Payment Plan is a free, optional program you sign up for through your drug plan that lets you spread out-of-pocket drug costs into monthly payments instead of paying it all at once at the pharmacy.
- Because plan drug lists and pharmacy networks can change each year, and IRMAA surcharges in 2026 start above $109,000 in income for single filers (based on 2024 taxes), it's worth reviewing your coverage during the Annual Enrollment Period.
Here's a plain-language guide to what's changing, and where to get help locally.
The Part D cap, explained simply
In 2027, no one with a Medicare Part D plan will pay more than $2,400 out of pocket for covered prescription drugs in a calendar year. Once your spending on covered medications hits that ceiling, you pay nothing for the rest of the year on those drugs.
This cap applies whether your drug coverage comes through a stand-alone Part D plan or is built into a Medicare Advantage plan that includes prescription coverage. It replaces the old "catastrophic" threshold that used to leave beneficiaries paying a small percentage of very high drug costs indefinitely.
For anyone in Edmond who takes expensive brand-name medications — such as certain diabetes, cancer, or autoimmune drugs — this is one of the biggest structural changes to Medicare in years.
Goodbye, "donut hole"
For nearly two decades, the "coverage gap" — commonly called the donut hole — was a confusing middle phase where Part D members suddenly paid more once their drug spending crossed a threshold. As of 2025, that phase is gone. Part D now has just three phases:
1. Deductible phase — you pay full negotiated price until you meet the plan deductible (up to a maximum of $700 in 2027). 2. Initial coverage phase — you pay copays or coinsurance until your out-of-pocket total reaches $2,400. 3. Catastrophic phase — you pay nothing for covered drugs the rest of the year.
That's it. No more sudden jump in cost mid-year.
The Medicare Prescription Payment Plan
Even with the $2,400 cap, some people still face a large bill early in the year — for example, if a $600 prescription is filled in January.
That's what the Medicare Prescription Payment Plan is designed to help with. It's a free, optional program that lets you spread your out-of-pocket drug costs across monthly payments through the year, instead of paying the pharmacy the full amount up front. You still owe the same total, but the timing is smoother.
Key things to know:
- You must opt in — it's not automatic.
- You can sign up before the plan year starts or any time during the year.
- You pay $0 at the pharmacy for covered drugs after enrolling; the plan bills you monthly instead.
- If you have very low drug costs, this program may not help you and could add paperwork.
Anyone with a Part D plan is eligible. You sign up through your drug plan, not through Medicare directly.
What this means locally in Edmond
Edmond sits in Oklahoma County, and Medicare plan availability is set at the county level. Beneficiaries here typically have access to a wide range of stand-alone Part D plans and Medicare Advantage plans with drug coverage, offered by multiple carriers. The exact list changes every year, which is why the Annual Enrollment Period exists.
Because plans update their formularies (their lists of covered drugs) and pharmacy networks each year, a plan that worked well for you in 2026 may not be the best fit for 2027 — even without the new cap amount. It's worth checking.
Dates to circle
- Oct. 15 – Dec. 7, 2026: Annual Enrollment Period. Join, switch, or drop a Part D or Medicare Advantage plan for 2027 coverage.
- Jan. 1, 2027: New coverage starts. The $2,400 cap and $700 maximum deductible take effect.
- Jan. 1 – March 31, 2027: Medicare Advantage Open Enrollment. If you're already in a Medicare Advantage plan, you get one chance to switch to another Advantage plan or return to Original Medicare.
Also worth noting: higher-income beneficiaries pay an IRMAA surcharge on Part B and Part D premiums. In 2026, those surcharges begin above $109,000 in income for a single filer (based on your 2024 tax return).
