Medicare Part D

How Rancho Cucamonga residents can pay Part D drug costs monthly in 2027

RANCHO CUCAMONGA, Calif. — If a large prescription bill at the pharmacy counter has ever caught you off guard, Medicare now offers a way to handle those costs a little differently. The Medicare Prescription Payment Plan lets people with a Part D drug plan spread their out-of-pocket drug costs over the calendar year in monthly amounts, instead of paying the full share the moment a prescription is filled.

It is not a discount program and it does not change what a drug costs. It changes when you pay.

What the payment plan actually does

Under normal Part D rules, when you pick up a prescription, you pay your share (a copay, coinsurance, or the deductible amount) right there at the pharmacy. If you take an expensive medication, that share can be hundreds of dollars in a single visit — especially early in the year, before you have moved through the deductible phase.

The Medicare Prescription Payment Plan changes that flow. If you opt in, you pay $0 at the pharmacy for covered Part D drugs. Your plan then sends you a monthly bill for what you would have owed, spread across the remaining months of the year.

Two things to be clear about:

• The total you owe over the year is the same. You are not saving money; you are smoothing payments.
• This only applies to Part D covered drugs. It does not cover Part B drugs, over-the-counter items, or anything your plan does not cover.

Who tends to benefit — and who may not

This option was designed with a specific problem in mind: a single big bill at the pharmacy that is hard to absorb in one month.

It may help if you:

• Take a high-cost brand-name drug and expect to hit a large share of the annual out-of-pocket cap ($2,100 in 2026, $2,400 in 2027) early in the year.
• Would rather budget a predictable monthly amount than face an uneven bill in January or February.
• Have had trouble in the past picking up a prescription because of the cost that day.

It may not do much for you if:

• Your prescriptions are generics with small, steady copays each month.
• You do not expect your yearly drug costs to add up to much.
• You are comfortable paying at the counter and prefer not to manage another monthly bill.

One caution: if you enroll and then do not pay the monthly bills from the plan, you can be removed from the payment program. You would still keep your Part D coverage, but you would go back to paying the pharmacy directly.

How to opt in — or out

You sign up through your Part D plan or your Medicare Advantage plan with drug coverage — not through Medicare directly. Every Part D plan is required to offer this option.

You can:

• Opt in before the plan year begins, so it applies from January.
• Opt in any month during the year. Your plan has to process the request within a set timeframe.
• Opt out at any time and return to paying at the pharmacy.

To start, call the member services number on your plan ID card, or check your plan's website for a "prescription payment plan" election form. If you want to compare Part D options during the Annual Enrollment Period (October 15 – December 7) or the Medicare Advantage Open Enrollment Period (January 1 – March 31), medicare.gov's Plan Finder is the official tool.

Rancho Cucamonga is in San Bernardino County, where a range of stand-alone Part D plans and Medicare Advantage plans with drug coverage are offered. All of them must make this monthly payment option available to enrollees, per CMS rules.

How it fits with 2027 Part D changes

The payment plan works alongside other Part D rules that took effect recently:

• The old coverage gap ("donut hole") is gone as of 2025. Part D now has three phases: deductible, initial coverage, and catastrophic.
• In 2027, once your out-of-pocket spending on covered drugs reaches $2,400, you pay nothing for covered Part D drugs for the rest of the year. The 2026 figure was $2,100.
• The maximum Part D deductible is $700 in 2027, up from $615 in 2026, though many plans set theirs lower.
• Higher-income enrollees may pay an IRMAA surcharge on top of their Part D premium; for single filers in 2026, that begins above $109,000 in income.

Even with the annual cap in place ($2,400 in 2027), someone with a very expensive drug could hit much of that cap in the first month or two. That is exactly the situation the monthly payment option was built for.

What to think about before you decide

A short checklist before you call your plan:

• Look at what you paid for prescriptions last year and when those costs hit.
• Ask your plan what your estimated monthly bill would be if you opted in.
• Consider whether you would rather one predictable monthly amount or pay-as-you-go at the counter.
• Remember: opting in is not permanent. You can leave the program if it does not fit.
