January is the most expensive month for Part D. The deductible resets, and one refill of a brand-name drug can land you with a bill of several hundred dollars before the year has even started. Medicare’s Prescription Payment Plan doesn’t lower that cost, but it lets you pay it in smaller monthly pieces instead of all at the pharmacy counter.
Open enrollment runs October 15 through December 7, so now is a good time to find out whether it fits your budget for 2027.
What the Medicare Prescription Payment Plan Is
The plan is a payment option for people with Medicare drug coverage. Instead of paying your out-of-pocket drug costs when you pick up each prescription, you pay $0 at the pharmacy. Your Part D plan then sends you a bill each month.
- Every Part D plan must offer it, including Medicare Advantage plans that include drug coverage.
- It is opt-in. Nobody is enrolled automatically.
- There is no fee to use it, and you can opt out at any time.
- It covers every drug your plan covers, not just expensive ones.
Why January Hurts: the 2027 Numbers
Under the standard Part D benefit in 2027, you pay the first $700 as a deductible. After that you pay 25% of each prescription’s cost until your out-of-pocket spending reaches $2,400 for the year. Once you hit that cap, covered drugs cost you nothing for the rest of the year. In 2026 the deductible is $615 and the cap is $2,100.
That means a person on an expensive medication can face a large share of the $2,400 in the first few months of the year. The payment plan spreads that same total across the remaining months.
A Worked Example: $700 in January
Here is a simplified illustration. Your plan runs the real math, so treat these numbers as a guide.
- In January you fill a prescription that costs you the full $700 deductible.
- Without the plan, you pay $700 at the counter.
- With the plan, you pay $0 at the counter. Your January bill is $700 divided by the 12 months left in the year, or about $58.33.
- If you fill nothing else, you keep paying about $58 a month. If you fill more drugs, the remaining balance is re-divided over the months left, so the monthly amount can rise.
The most you can owe in any single month is also limited. For someone who opts in at the start of 2027, the first month’s bill is capped at $200, which is the $2,400 cap divided by 12.
Who Benefits and Who Should Skip It
| Your situation | Payment plan a good fit? | Why |
|---|---|---|
| One or more costly brand-name drugs | Yes | Early-year costs are high, so splitting them smooths your budget. |
| Likely to reach the $2,400 cap before December | Yes | You pay the same total, but in installments. |
| Only low-cost generics, small monthly copays | Probably not | Your costs are already small, so there is little to spread. |
| You get Extra Help (Low-Income Subsidy) | Usually not | Extra Help already brings low, fixed copays, which is typically a better deal. |
The plan does not reduce what you owe. It only changes when you pay it. If you expect your total to be small, you gain little by adding a monthly bill.
How to Join
- Call, write to, or go online with your Part D plan. The number is on your member ID card.
- Tell them you want to opt in to the Medicare Prescription Payment Plan.
- Ask whether it is effective right away. You can opt in at the start of the plan year or in any month after.
- Watch for your first monthly bill and set a reminder for the due date.
What Happens if You Miss a Payment
If a monthly bill goes unpaid, your plan sends a notice and gives you a 2-month grace period to catch up. If you still don’t pay, you are removed from the payment plan, but you stay enrolled in your Part D plan and keep your drug coverage. If you pay the overdue amount, or show good cause such as serious illness or a disaster, you can stay in the plan.
If you leave the plan, any balance you already owe is still due.
Checklist Before Open Enrollment Ends December 7
- List your prescriptions and estimate what you’d pay in January with the $700 deductible.
- Check whether you receive Extra Help. If so, ask your plan whether the payment plan adds anything.
- Compare 2027 plans in the Medicare Plan Finder, since the payment plan works the same way across plans but your drug prices won’t.
- Decide on a budget date each month for the payment.
