Medicare Part D

$2,100 Part D Ceiling Arrives Jan 1 for Rancho Cordova

RANCHO CORDOVA, Calif. — Starting January 1, 2026, people with Medicare Part D drug coverage will hit a firm ceiling on what they pay out of pocket for prescriptions: $2,100 for the year. Once you reach it, you pay nothing more for covered drugs until the calendar resets. For local residents comparing coverage during this fall's Annual Enrollment Period, which runs through December 7, understanding how the cap works — and how to spread costs over the year — is one of the most important decisions on the table.

What the $2,100 cap actually means

The $2,100 figure is the maximum you can be asked to pay out of pocket for covered Part D drugs in 2026, according to CMS. It applies whether your drug coverage comes through a stand-alone Part D plan or is built into a Medicare Advantage plan.

The cap only counts what you pay for drugs on your plan's formulary. Premiums don't count toward it. Neither do drugs your plan doesn't cover. So if a prescription isn't on your plan's list, spending on it won't move you closer to the ceiling.

The Part D deductible is also capped in 2026, at $615. Plans can charge less than that, but not more.

The coverage gap is gone

For years, people learned to dread the "donut hole" — a middle stretch where costs suddenly jumped after you and your plan had spent a certain amount. That gap was eliminated in 2025, and it stays gone in 2026.

Part D now has three phases instead of four:

1. Deductible phase — you pay the full negotiated price until you meet the deductible (up to $615). 2. Initial coverage phase — you pay a copay or coinsurance while your plan pays the rest. 3. Catastrophic phase — once your out-of-pocket spending hits $2,100, you pay $0 for covered drugs for the rest of the year.

That third phase used to require thousands more in spending before kicking in. The new structure is simpler and easier to plan around.

The Medicare Prescription Payment Plan

Even with a $2,100 ceiling, hitting that number in January or February can sting. That's where the Medicare Prescription Payment Plan comes in.

This is a free, optional program available through every Part D plan. Instead of paying the pharmacy at pickup, you get a monthly bill from your plan that spreads your out-of-pocket drug costs across the remaining months of the year. You still owe the same total — the program doesn't lower your costs — but it evens out the cash flow.

It tends to help most if you take an expensive specialty medication or expect a big bill early in the year. It may not help much if your drug costs are low and steady. You can opt in before the year starts or at any point during the year by contacting your plan.

How Rancho Cordova residents can decide

Rancho Cordova is in Sacramento County, where residents can choose from a range of stand-alone Part D plans and Medicare Advantage plans that include drug coverage. Because formularies, pharmacy networks, and cost-sharing rules vary from plan to plan, the same medication can be priced very differently across options.

A few practical steps for this enrollment season:

• Make a current drug list. Include dosages and how often you fill each prescription.
• Use the Plan Finder at medicare.gov. It lets you enter your drugs and ZIP code, then estimates your yearly out-of-pocket cost under each available plan.
• Check the pharmacy network. A plan's price can change depending on whether your pharmacy is "preferred," standard, or out of network.
• Ask about the payment plan. If you expect high drug costs, find out how to enroll in the Medicare Prescription Payment Plan through the plan you're considering.

Higher-income enrollees should also note that IRMAA surcharges — extra amounts added to Part B and Part D premiums — begin above $109,000 in income for a single filer in 2026.

Deadlines to keep in mind

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