Medicare Part D

What the new Medicare Part D cap means in Mission, Texas

MISSION, Texas — On Jan. 1, 2027, the hard yearly ceiling on what you pay out of pocket for covered Part D prescriptions rises to $2,400, up from $2,100 in 2026. The structure that took effect in 2026 continues, with a higher cap for the new plan year.

That single number is the headline of a broader structure that also keeps the old "donut hole" closed and lets you spread your drug costs across the year in monthly installments. Here's a plain-language guide to what's new for 2027, what stays the same, and what to check before the Annual Enrollment Period closes on December 7.

The $2,100 out-of-pocket cap, explained

Under Medicare Part D rules, once your out-of-pocket spending on covered prescription drugs reaches the yearly cap, you pay nothing more for the rest of the calendar year on those covered drugs. The cap is $2,100 in 2026 and $2,400 in 2027. It resets each January.

A few important details from CMS:

• The cap applies to covered Part D drugs. Drugs your plan doesn't cover don't count toward it.
• Your plan premium does not count toward the $2,100.
• The Part D deductible in 2026 is capped at $615. Plans can set a lower deductible, but not a higher one.
• The cap is per person, not per household.

For people who take expensive specialty medications, hitting that ceiling early in the year means predictable costs for the months that follow — something Part D has never offered before.

The "donut hole" is gone

If you've been on Medicare for a while, you probably remember the coverage gap — the stretch where you paid more out of pocket after your plan and you had spent a certain amount together. That phase was eliminated in 2025.

Part D now has just three phases:

1. Deductible — you pay the full negotiated price until you meet the plan's deductible (up to $700 in 2027). 2. Initial coverage — you pay a copay or coinsurance; your plan pays the rest. 3. Catastrophic coverage — once your out-of-pocket spending reaches the yearly cap ($2,400 in 2027), you pay nothing more for covered drugs the rest of the year.

No more confusing middle stage. No more sticker shock in the summer when someone suddenly landed in the gap.

The Medicare Prescription Payment Plan

Hitting the yearly cap in January or February is still that full amount out of your pocket. To help with that, Medicare offers the Medicare Prescription Payment Plan — sometimes called "M3P" — which lets you spread your covered drug costs across the calendar year in monthly bills instead of paying all at once at the pharmacy.

Key things to know:

• It's optional and free to join. There's no interest or fee.
• You still owe the same total amount — it's smoothed, not reduced.
• You can opt in before the plan year starts or at any point during the year.
• Once enrolled, you pay $0 at the pharmacy counter for covered drugs and get a monthly bill from your plan.

This tends to help most if you take a high-cost drug and would otherwise face a big bill in the first few months of the year. If your drug costs are low and steady, the payment plan may not change much for you. You can learn more or sign up through your Part D plan or at medicare.gov.

Before Dec. 7, it's worth taking a few minutes to:

• Log in to your account at medicare.gov and run the Plan Finder with your current medication list.
• Confirm each drug you take is still on your plan's formulary for 2027.
• Check whether your preferred pharmacy is still in network.
• Review any Annual Notice of Change (ANOC) letter your plan mailed in September.

If you'd rather talk to a person, call 1-800-MEDICARE or reach out to Texas's State Health Insurance Assistance Program (SHIP), called the Health Information, Counseling and Advocacy Program (HICAP) in Texas, for free one-on-one help. There is no charge and no sales pressure.

A note on higher-income households

If your income is above $109,000 as a single filer (or above the corresponding threshold for joint filers) on your most recent IRS return used by Social Security, you may pay an IRMAA surcharge on top of your standard Part B and Part D premiums in 2026. IRMAA is set by Social Security, not by your plan, and it's based on tax returns from two years earlier. If your income has dropped since then — for example, because of retirement — you can ask Social Security to reconsider.
