Medicare Part D

$2,400 Part D Cap in Helena, Mont. for 2027

Helena, Mont. — Starting Jan. 1, 2027, people with Medicare drug coverage will see the annual out-of-pocket limit on prescriptions rise to $2,400, up from $2,100 in 2026. The cap itself first took effect in 2025 at $2,000. For Helena residents managing costly medications, it remains one of the most significant Part D features — and plan choices for 2027 are made during Medicare's Annual Enrollment Period, which runs Oct. 15 through Dec. 7, 2026.

Here's a plain-language look at what's changing, what stays the same, and where to get answers you can trust.

The Part D cap, explained

Once your out-of-pocket spending on covered Part D drugs hits $2,400 in 2027 (it is $2,100 in 2026), you owe nothing more for the rest of the calendar year on those covered prescriptions. The cap resets each January.

A few things worth knowing:

• The cap applies to covered Part D drugs. Medications your plan doesn't cover don't count toward it.
• Premiums do not count toward the annual cap.
• The cap applies whether your drug coverage comes through a stand-alone Part D plan or a Medicare Advantage plan that includes drug coverage.

This is a program-wide rule set by CMS, so it works the same in Helena as it does anywhere else in the country.

The "donut hole" is gone

If you've been on Medicare for a while, you may remember the coverage gap — the dreaded "donut hole" where your share of drug costs jumped after you hit a spending threshold. That phase was eliminated in 2025.

Part D now has just three phases:

1. Deductible phase — you pay the 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 share of the cost (a copay or coinsurance) and your plan pays the rest. 3. Catastrophic phase — once your out-of-pocket spending reaches the annual cap ($2,100 in 2026, $2,400 in 2027), you pay nothing more for covered drugs the rest of the year.

Simpler math, fewer surprises.

The Medicare Prescription Payment Plan

Hitting the annual cap is good news at year's end — but what if a big prescription bill lands in January or February? That's what the Medicare Prescription Payment Plan is designed to help with.

It's a free, optional program that lets you spread your out-of-pocket drug costs across the calendar year in monthly payments instead of paying the pharmacy all at once. You still owe the same amount overall; you just pay your plan monthly instead of the pharmacy at pickup.

To sign up, you contact your drug plan directly — not the pharmacy, and not Medicare. It may be most useful for people who take expensive medications early in the year, or whose costs are uneven month to month. It isn't the right fit for everyone, and Medicare has a worksheet on medicare.gov to help you think it through.

Higher-income surcharges (IRMAA) in 2027

If your income is above certain thresholds, you pay an extra amount on top of your Part B and Part D premiums, called IRMAA. For 2026, the surcharge begins for single filers with income above $109,000, and higher thresholds apply for joint filers. Social Security uses your tax return from two years prior to figure this out, and you can appeal if your income has since dropped due to a life event like retirement or the death of a spouse.

What Helena shoppers should do during AEP

Helena is in Lewis and Clark County, where plan availability — the number of stand-alone Part D plans and Medicare Advantage plans offered — is set at the county level by CMS and participating carriers. Every fall, plans can change their formularies (the list of drugs they cover), their pharmacy networks, and their cost-sharing. That's why reviewing your Annual Notice of Change letter matters, even if you're happy with your current coverage.

A few practical steps:

• Read the Annual Notice of Change your plan mailed you in September.
• Make a current list of your prescriptions, doses, and preferred pharmacy.
• Use the Plan Finder at medicare.gov to compare how your drugs are covered under the plans available in Lewis and Clark County.
• If something is confusing, call 1-800-MEDICARE (1-800-633-4227) or Montana's State Health Insurance Assistance Program (SHIP), which offers free, unbiased counseling.

Key dates to keep in mind:

• Oct. 15 – Dec. 7, 2026: Annual Enrollment Period. Changes take effect Jan. 1, 2027.
• Jan. 1 – March 31, 2027: Medicare Advantage Open Enrollment. If you're already in a Medicare Advantage plan, you get one chance to switch to another MA plan or return to Original Medicare.

Reader questions

Does the cap ($2,100 in 2026, $2,400 in 2027) include what I spend on insulin or vaccines? Insulin covered by Part D is capped separately at $35 for a month's supply, and most recommended adult vaccines are $0 under Part D. Your out-of-pocket spending on covered drugs still counts toward the $2,100 in 2026 ($2,400 in 2027) annual cap.

If I don't take many prescriptions, does this change matter to me? Maybe not right now — but Part D is also insurance against future costs. A single new specialty medication can push anyone toward the cap quickly, and the cap is now a guaranteed backstop.

Can I join the Prescription Payment Plan mid-year? Yes. You can opt in at any point during the year by contacting your Part D or Medicare Advantage drug plan. Joining earlier in the year generally gives you more months to spread costs across.

What if my income dropped after I retired — am I stuck with IRMAA? No. You can file Form SSA-44 with Social Security to request a reconsideration based on a qualifying life-changing event, including retirement.
