Medicare drug plan members can spread their 2027 prescription costs across the year instead of paying a big bill at the pharmacy in January. The Medicare Prescription Payment Plan lets Part D enrollees pay out-of-pocket drug costs in monthly installments, and it is open to everyone with drug coverage regardless of income. It does not lower what anyone owes, only when the money is due.
The standard Part D deductible in 2027 is $700, and the yearly cap on out-of-pocket drug spending is $2,400, according to KFF. Enrollment in the monthly plan is voluntary, and Medicare’s own fact sheet says “there’s no cost to participate.”
Anyone on a Part D plan, whether a stand-alone drug plan or a Medicare Advantage plan with drug coverage, can ask for the monthly option by contacting that plan. KFF’s open enrollment explainer describes the program as available to all Part D enrollees. Anyone with limited income who is asking whether help exists should look at Extra Help, a separate program, covered below.

How the monthly bills are figured
Under the plan, the pharmacy no longer collects at the counter. The drug plan bills the member each month instead, and any monthly premium is still paid separately, according to the Medicare fact sheet, published in September 2026. The covered period is the calendar year, January through December.
Each month’s bill equals what the person would have paid for prescriptions that month, plus any balance carried from earlier months, divided by the number of months left in the year. The first month has a ceiling. It is the lesser of the actual cost or the $2,400 yearly maximum divided by 12, which is $200.
That ceiling is what softens January. The $700 deductible is the first cost many members meet, and under the plan the January bill cannot exceed $200 even when the fills cost more. Medicare’s example starts with $600 in drug costs every month beginning in January 2027. The January bill is $200, then $90.91 in February and $150.91 in March.
The bill peaks at $217.58 in April, the month the $2,400 out-of-pocket maximum is reached, and holds at $217.57 from May through December. The total is $2,400, the same as without the plan. Payments can rise later in the year when new costs are added, because fewer months remain to spread them across.
Costs already paid earlier in the year count too. In the fact sheet’s April example, a member who has already paid $15 out of pocket starts with a first-month cap of $2,385, spread over the nine months that remain.
Who gains, and who does not
The fact sheet says the plan helps most people with high drug costs early in the year who sign up before September. It may not suit people with low or steady costs, people who sign up late in the year, people eligible for Extra Help or a Medicare Savings Program, or people who receive other drug assistance.
The reason is simple. Someone whose drugs cost little gains nothing from a payment schedule, and a person already getting help with costs has less to spread out. The plan changes timing. It never changes the $2,400 total.
Signing up, staying in and leaving
People can join at any point in the calendar year by contacting their plan, the fact sheet says, and participation renews automatically each year unless the person changes plans or opts out. Leaving is as simple as joining: a call to the plan ends it. The remaining balance is still owed and can be paid at once or in monthly bills.
Changing to a different Medicare drug or health plan ends participation, so anyone who switches during open enrollment, which runs Oct. 15 to Dec. 7, has to re-enroll with the new plan, the fact sheet says. Every Medicare drug plan is required to offer the benefit, the Centers for Medicare & Medicaid Services says.
Missed payments do not bring interest or late fees. A member gets a reminder before any removal, though a member who does not pay by the reminder’s deadline can be removed from the plan. Drug coverage itself stays in place either way.
Extra Help is a different program
Extra Help is the Social Security program that actually lowers Part D premiums, deductibles and drug costs, for people with limited income and resources. Applications go through Social Security. The monthly payment plan is available to everyone, and Extra Help is the route for people who qualify by income and savings.
Medicare’s fact sheet says people eligible for Extra Help may find the monthly plan less useful, which is the point of the difference. The open question for most households is which of the two fits the budget, and the answer starts with the Part D plan’s own drug list and the person’s income.
Drug costs eating the monthly budget?
A switch during open enrollment ends the monthly drug payment arrangement, and the plan year starts Jan. 1. A member who does not re-enroll with the new plan can find the January pharmacy bill back at the counter.
