Part D in 2027: Reading's Guide to the $2,400 Cap

By the numbers

Reading, Pa. — What Changes for Part D in 2027

If you take prescription drugs and have Medicare, 2027 brings continued updates to how your coverage works. For folks here in Reading, the headline number is simple: once you spend $2,400 out of pocket on covered drugs in 2027, you're done paying for them for the rest of the year.

That cap is set by Medicare and applies the same way whether you live in Reading, Wyomissing, or anywhere else. But the plan choices available to you are decided at the county level. Reading is in Berks County, where Medicare beneficiaries can compare Part D drug plans and Medicare Advantage plans that include drug coverage during the fall enrollment window.

Here's a plain-language walk-through of how Part D actually works in 2027.

The Deductible: Where Costs Start

Every Part D plan is allowed to charge a deductible before drug coverage kicks in. For 2027, the maximum deductible any plan can charge is $700. Some plans charge less than that, and some charge nothing at all for certain drug tiers. The exact amount depends on the plan you pick.

Once you've paid the deductible (if your plan has one), you move into the next phase.

The Three Phases of Part D in 2027

Medicare used to have a confusing "donut hole" in the middle of the year. That coverage gap was eliminated in 2025, and in 2027 there are just three phases:

1. Deductible phase — You pay full negotiated price for your drugs until you hit your plan's deductible (up to $700 in 2027). 2. Initial coverage phase — You pay a copay or coinsurance, and your plan pays the rest. This continues until your out-of-pocket spending reaches the annual cap. 3. Catastrophic phase — Once your out-of-pocket drug costs hit $2,400 for the year in 2027, you pay $0 for covered drugs through the end of the calendar year.

That $2,400 cap is a big deal. Before 2024, there was no yearly limit at all on what you could spend on Part D drugs. Now there is.

The Monthly Payment Plan Option

Medicare also offers something called the Medicare Prescription Payment Plan. It doesn't lower your drug costs — it spreads them out. Instead of paying a large amount at the pharmacy counter one month, you can choose to pay your yearly share in level monthly bills.

This is optional and free to sign up for. It can help if you have a costly prescription early in the year and don't want a big hit all at once. You can enroll through your Part D plan.

A Word on Higher-Income Surcharges (IRMAA)

If your income is above a certain level, Medicare charges an extra monthly amount on top of your Part D premium, called IRMAA (the Income-Related Monthly Adjustment Amount). For 2026, IRMAA starts kicking in for single filers with income above $109,000, and at a higher threshold for married couples filing jointly. Social Security uses your tax return from two years earlier to decide.

If your income has dropped since then — say, because you retired — you can ask Social Security to reconsider.

Plan Availability in Berks County

Reading is in Berks County, where Medicare beneficiaries can choose from a range of stand-alone Part D drug plans as well as Medicare Advantage plans that bundle in drug coverage. The exact list changes every year, and plans can adjust their formularies (the list of covered drugs), pharmacy networks, and costs.

The best way to see what's offered in Berks County is to use the Plan Finder tool at medicare.gov, which lets you enter your ZIP code and your prescriptions to compare what's available.

Key Dates to Circle

• October 15 – December 7, 2026: Annual Enrollment Period. This is when you can join, switch, or drop a Part D or Medicare Advantage plan for 2027.
• January 1 – March 31: Medicare Advantage Open Enrollment. If you're already in a Medicare Advantage plan, you get one chance in this window to switch to another one or return to Original Medicare.

Missing the fall window usually means waiting a full year to make changes, so mark those dates.
