Medicare Part D

Part D Rules for 2027: Apache Junction, Ariz.

APACHE JUNCTION, Ariz. — If you take prescription drugs and have a Medicare Part D plan, the way you pay at the pharmacy counter is changing again on Jan. 1, 2027. The out-of-pocket ceiling is moving up to $2,400, the old "donut hole" stays gone, and there is a payment option that lets you spread big drug bills across the calendar year. Here is what Apache Junction readers should understand before they pick up their first refill of the new year.

What the Part D cap actually means

The Part D out-of-pocket cap is $2,100 in 2026 and $2,400 in 2027. Once your spending on covered prescriptions reaches that number, you move into what Medicare calls the catastrophic phase, and you pay nothing for the rest of the calendar year on drugs your plan covers.

A few important details:

• The cap only counts spending on drugs your Part D plan actually covers. Drugs that aren't on your plan's formulary don't count toward it.
• The cap resets every Jan. 1.
• Part B drugs (things usually given in a doctor's office, like many infusions) are separate — they do not count toward the Part D cap.
• Plans can still charge a deductible in 2027, up to a maximum of $700 before standard cost-sharing kicks in.

The donut hole is gone — for good

For years, Part D had a confusing middle stage called the coverage gap, where costs could jump before catastrophic coverage started. That phase was eliminated in 2025 and stays gone in 2027.

Part D now has three phases:

1. Deductible phase — you pay full negotiated price until you meet your plan's deductible (up to $700 in 2027). 2. Initial coverage phase — you pay a copay or coinsurance for each prescription until your out-of-pocket total hits $2,400. 3. Catastrophic phase — you pay nothing for covered drugs for the rest of the year.

That's it. No more donut hole math.

The Medicare Prescription Payment Plan

Even with the cap ($2,100 in 2026, $2,400 in 2027), $2,100 in January is still a lot of money at once, especially if you take a high-cost specialty drug. This is where the Medicare Prescription Payment Plan comes in.

Here is how it works:

• It is optional and free to join. You are not charged interest or fees.
• Instead of paying the pharmacy directly for your share, your Part D plan pays the pharmacy and then bills you monthly.
• The bill is spread across the remaining months of the calendar year, so the earlier in the year you enroll and have a large fill, the more months you have to spread it over.
• You still owe the same total amount — the payment plan just changes the timing.

You sign up through your Part D plan, not through Medicare directly. Most people who benefit are those facing one or two expensive fills early in the year.

Common mistakes to avoid

A few missteps show up every year — worth watching out for as 2027 begins:

• Assuming the cap means "free drugs." You still pay until you hit $2,100 in 2026 ($2,400 in 2027). And drugs not on your plan's list don't count.
• Skipping the formulary check. Plans update their drug lists every year. A drug that was covered in 2026 may be tiered differently — or dropped — in 2027.
• Ignoring the Annual Notice of Change. Your plan mails this every fall. It is the single best summary of what will be different in 2027.
• Missing the enrollment windows. Oct. 15 – Dec. 7 is the Annual Enrollment Period. Jan. 1 – March 31 is Medicare Advantage Open Enrollment, when Advantage members can switch or drop back to Original Medicare.

Where Apache Junction fits in

Apache Junction is in Pinal County, and Part D plan availability is set at the county level. That means the plans available to a neighbor across the county line in Maricopa County may look different from the ones offered in Pinal. When you use Medicare's Plan Finder, it asks for your ZIP code for exactly that reason.

Whatever plan you choose, the cap ($2,100 in 2026, $2,400 in 2027), the $615 maximum deductible, and the payment plan option are program-level rules — they apply the same in Apache Junction as anywhere else in the country.

A note on higher incomes

If your income is above $109,000 as a single filer (or $218,000 filing jointly) in 2026, you may pay an Income-Related Monthly Adjustment Amount, or IRMAA, on top of your Part D premium. This is based on your tax return from two years earlier. Social Security notifies you if it applies to you.
