Medicare Part D

Simi Valley Part D enrollees can spread 2026 drug costs across 12 months

SIMI VALLEY, Calif. — If a big pharmacy bill early in the year has ever caught you off guard, Medicare now offers a way to smooth those costs out. The Medicare Prescription Payment Plan, which started in 2025 and continues in 2026, lets people with Medicare Part D pay their share of prescription costs in monthly amounts across the year instead of all at once at the counter.

It is a payment-timing tool, not a discount. You will owe the same total by December — you just spread it out.

What the payment plan actually does

Under normal Part D rules, you pay your share of a prescription when you pick it up. If one drug costs several hundred dollars in January, you pay several hundred dollars in January.

The Medicare Prescription Payment Plan changes the billing, not the price. Your Part D plan pays the pharmacy for your share, then sends you a monthly bill for that amount, divided across the months left in the year. You still owe the same total, and you keep paying your Part D premium separately.

Because Part D out-of-pocket spending is capped at $2,100 in 2026, the most anyone in the program could spread across a full year is that cap plus any deductible amounts allowed under the rules. The Part D maximum deductible in 2026 is $615.

Who it tends to help

This option is built for people whose drug costs are uneven — big in one month, small the next. That includes:

• People starting a high-cost specialty drug early in the year.
• People who hit the deductible in January and face a large first fill.
• People on a fixed monthly income who can plan around a predictable bill.

It may not help people whose drug costs are already low and steady each month. In that case, monthly billing could actually feel like more paperwork for the same total.

There is no income test. Anyone with a Part D plan or a Medicare Advantage plan that includes drug coverage can ask to join.

How to opt in

You sign up through your drug plan, not through Medicare directly. Every Part D plan and Medicare Advantage plan with drug coverage is required to offer the program.

You can:

• Call the member services number on the back of your plan ID card.
• Ask for the "Medicare Prescription Payment Plan" election request.
• Sign up before the plan year begins, or at any point during the year.

If you join mid-year, your remaining costs are spread across the months left in 2026, so monthly bills tend to be higher the later you join.

How to opt out

You can leave the program at any time. Contact your plan the same way you joined. After you opt out, you go back to paying your share at the pharmacy counter, and you still owe any balance already billed under the payment plan.

Missing payments matters. If you fall behind, the plan can remove you from the payment program, though it cannot drop you from your Part D coverage for that reason alone.

What Simi Valley residents should know

Simi Valley is in Ventura County, where Medicare Part D and Medicare Advantage plans follow the same federal rules as the rest of California. The payment plan option is the same no matter which county plan you have.

For personalized help comparing whether the payment plan makes sense with your prescriptions, California's State Health Insurance Assistance Program (SHIP) — known here as HICAP — offers free one-on-one counseling.

The Annual Enrollment Period, October 15 through December 7, is a good time to think about it, because you can also review whether your drug plan still fits your prescriptions for the coming year. Medicare Advantage Open Enrollment runs January 1 through March 31.
