Medicare Part D

Fargo, N.D.: Part D's $2,400 Cap for 2027

FARGO, N.D. — Starting January 1, 2027, no one enrolled in a Medicare Part D drug plan will pay more than $2,400 out of pocket for covered prescriptions in a calendar year. For Fargo residents who take costly medications — think insulin combinations, cancer pills, or specialty drugs for autoimmune conditions — this cap continues to reshape Part D, and the Annual Enrollment Period to lock in 2027 coverage runs through December 7.

The cap is a hard ceiling written into federal law. Once your covered drug spending reaches the yearly limit, your Part D plan pays 100% of the cost of covered drugs for the rest of the year. Here is what changed, what stayed the same, and how to think about it.

What the Part D cap actually covers

The cap applies to what you spend out of pocket on drugs that are covered by your Part D plan's formulary. That includes your deductible (no more than $615 in 2026, rising to no more than $700 in 2027), any copays, and coinsurance at the pharmacy counter.

It does not include your monthly Part D premium, and it does not apply to drugs your plan does not cover. It also does not include Part B drugs — those are medications given in a clinic, like most infusions, which fall under a different part of Medicare.

If your plan's formulary excludes a drug you take, you would pay full price for it and none of that would count toward the out-of-pocket cap. That is one reason it pays to check formularies during open enrollment.

The coverage gap is officially over

For years, Part D had a confusing middle stage called the "donut hole," where enrollees suddenly paid a bigger share of drug costs after hitting an initial coverage limit. The Inflation Reduction Act removed it starting in 2025, and the simpler structure has been in place since 2026.

Part D now has three phases:

1. Deductible phase — you pay full negotiated price until you meet your plan's deductible (no more than $615 in 2026 and no more than $700 in 2027). 2. Initial coverage phase — you pay a copay or coinsurance while your plan pays the rest. 3. Catastrophic phase — once your out-of-pocket total reaches the annual cap ($2,100 in 2026, $2,400 in 2027), you pay nothing for covered drugs the rest of the year.

No more math about which side of the donut hole you are on. No more sticker shock in July.

The monthly payment plan option

Even with the cap, hitting the yearly limit in the first quarter of the year is real for people on expensive medications. That is where the Medicare Prescription Payment Plan comes in. This is a free, optional program that lets you pay your share of drug costs to your plan in level monthly installments over the calendar year, instead of paying the pharmacy in full each visit.

You still owe the same total. You just spread it out. For a Fargo retiree facing a $600 pharmacy bill in January, this can be the difference between filling a prescription and skipping it.

You have to opt in — it is not automatic. You can sign up before the plan year starts or any month during the year by contacting your Part D or Medicare Advantage prescription drug plan directly. Medicare.gov has more detail on how the program works.

What Fargo residents should do during open enrollment

Fargo is in Cass County, where Medicare beneficiaries can choose between stand-alone Part D plans and Medicare Advantage plans that include drug coverage. Every plan has its own formulary, pharmacy network, and premium — and all of them have to honor the same federal out-of-pocket cap: $2,100 in 2026 and $2,400 in 2027. The 2027 plan lineup is detailed in each plan's Annual Notice of Change and on Medicare.gov's Plan Finder.

That means comparing plans is less about finding the "cheapest" and more about matching the plan to your actual prescriptions. A few questions worth asking before December 7:

• Is every drug I take on the plan's formulary for 2027? Formularies change annually.
• Which pharmacies in Fargo are in-network — and are they preferred?
• Does the plan require prior authorization or step therapy for anything I take?
• Would the monthly payment plan help me manage cash flow?

The Medicare Plan Finder at medicare.gov lets you enter your drugs and ZIP code to see how each plan would cover them.

A note on higher incomes

If your income was above $109,000 as a single filer (or $218,000 married filing jointly) on your 2024 tax return, you will pay an IRMAA surcharge on top of your Part B and Part D premiums in 2026. IRMAA does not affect the cap ($2,100 in 2026, $2,400 in 2027) — it only changes your premium.
