- The Annual Enrollment Period runs Oct. 15 through Dec. 7, and it's the main window to join, switch, or drop a Part D plan.
Here is a plain-language look at how Medicare Part D drug coverage works in 2027, and what Norman-area readers should keep in mind.
The 2027 deductible: up to $700
Every Part D plan has its own deductible — the amount you pay for covered drugs before the plan starts sharing the cost. In 2027, Medicare sets the ceiling for that deductible at $700 (it was $615 in 2026). Plans can charge less, and some charge nothing, but no stand-alone Part D or Medicare Advantage drug plan can charge more than $700.
Once you meet the deductible (if your plan has one), you move into the next phase.
The $2,400 out-of-pocket cap
This is the headline change many Norman residents have been waiting for. In 2026, once your out-of-pocket spending on covered prescription drugs reaches $2,100, you pay $0 for the rest of the calendar year on covered drugs. This cap applies to every Medicare drug plan in the country — it's a program rule, not a plan-by-plan feature.
That cap resets each January, so your spending starts over at the beginning of 2028.
The three phases of Part D in 2027
Before 2025, Part D had four phases, including the dreaded coverage gap known as the donut hole. That gap has been eliminated. Here are the three phases you'll move through in 2027, in order:
1. Deductible phase. You pay the full negotiated price of your drugs until you meet your plan's deductible (up to $700 in 2027). If your plan has no deductible, you skip this phase.
2. Initial coverage phase. You and your plan share the cost of your drugs. You typically pay a copay or coinsurance while the plan pays the rest. You stay in this phase until your out-of-pocket spending hits $2,400.
3. Catastrophic phase. Once you hit the $2,400 cap, you pay nothing for covered drugs for the rest of the year.
That's it. Three phases, one cap, and no more math about "true out-of-pocket" costs in a coverage gap.
The Medicare Prescription Payment Plan
Even with the cap, hitting $2,400 in January or February can be a shock if you take expensive medications. That's why Medicare offers the Medicare Prescription Payment Plan, which lets you spread your drug costs into monthly payments across the calendar year instead of paying at the pharmacy counter.
It's free to sign up, it doesn't lower your total cost, and it's optional. You still pay the same amount over the year — just in more predictable monthly bills. Any Part D or Medicare Advantage plan with drug coverage must offer it. You can enroll through your plan any time during the year.
A note on higher incomes (IRMAA)
Most people pay only their plan's Part D premium. But if your income is above $109,000 as a single filer in 2026 (or above the corresponding joint-filer threshold), Medicare adds an Income-Related Monthly Adjustment Amount (IRMAA) on top of your Part D premium. Social Security uses your tax return from two years earlier to set this. If your income has dropped because of a life event like retirement, you can ask Social Security to reconsider.
What Norman-area readers should know about availability
Norman is in Cleveland County, where Medicare beneficiaries have a range of stand-alone Part D drug plans and Medicare Advantage plans that include drug coverage to choose from. Plan availability is set at the county level, so two neighbors on opposite sides of a county line can see different options. The 2027 lineup is detailed in each plan's Annual Notice of Change and on the Plan Finder at medicare.gov.
Key dates to circle
- Oct. 15 – Dec. 7, 2026: Annual Enrollment Period. Join, switch, or drop a Part D or Medicare Advantage plan for coverage starting Jan. 1, 2027.
- Jan. 1 – Mar. 31, 2027: Medicare Advantage Open Enrollment Period. If you're already in a Medicare Advantage plan, you can switch to a different one or return to Original Medicare (and add a stand-alone Part D plan).
Missing the fall window usually means waiting a full year to change coverage, unless you qualify for a Special Enrollment Period.

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