Medicare Part D

Costa Mesa, CA: Part D Cost Ceiling for 2027

Costa Mesa, CA — If you take prescription drugs and have Medicare, the way you pay for them is changing again on January 1, 2027. The firm annual ceiling on what you can spend out of pocket at the pharmacy counter under Part D rises — and a payment option still lets you spread those costs across the year instead of getting hit all at once.

Here is what that means in plain English, and the mistakes to sidestep before you fill your first prescription of the new year.

The out-of-pocket cap, explained

Starting January 1, 2027, once you have paid $2,400 out of pocket for covered prescription drugs under a Medicare Part D plan, you pay nothing for the rest of the calendar year for those covered drugs. The cap resets every January.

A few things to keep in mind:

• The $2,100 in 2026 ($2,400 in 2027) counts what you pay toward covered drugs — deductibles, copays, and coinsurance. Monthly plan premiums do not count toward it.
• Only drugs covered by your plan's formulary count. If you fill a prescription that your plan does not cover, that spending does not move you toward the cap.
• The cap applies to Part D drugs (the ones you pick up at the pharmacy), not to drugs given in a doctor's office, which usually fall under Part B.

The Part D maximum deductible is $615 in 2026 and $700 in 2027. Plans can set a lower deductible, but not a higher one.

The coverage gap is really gone

For years, the "donut hole" was the confusing middle stage where costs jumped up after you and your plan had spent a certain amount together. That gap was eliminated in 2025, and 2027 keeps the simpler three-phase structure:

1. Deductible phase — you pay the 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, and your plan pays the rest, until your out-of-pocket spending hits $2,400. 3. Catastrophic phase — you pay nothing for covered drugs for the remainder of the year.

That's it. No fourth stage, no surprise price spike halfway through the year.

The Medicare Prescription Payment Plan

Here's the piece a lot of people miss. Even with the $2,400 cap in 2027, a single expensive prescription in January could still mean a big bill on day one.

The Medicare Prescription Payment Plan is an optional program that lets you pay nothing at the pharmacy and instead get a monthly bill from your Part D plan. Your total for the year does not change — you still owe what you owe — but it's spread across the remaining months of 2027 instead of landing all at once.

A few things worth knowing:

• You have to opt in. It is not automatic.
• You can sign up before the year starts or at any point during the year, though signing up earlier spreads the cost over more months.
• If you generally have low, steady drug costs, this program may not help you much. It is designed for people facing large one-time or front-loaded pharmacy bills.

You can request it through your Part D plan. Medicare.gov has a plain-language overview and a checklist to help you decide.

Enrollment windows to circle

Costa Mesa is in Orange County, where beneficiaries can choose from 92 Medicare Advantage plans offered by 16 carriers in 2027, along with stand-alone Part D plans. The two windows that matter most:

• Annual Enrollment Period: October 15 – December 7, 2026. This is when you can join, switch, or drop a Part D or Medicare Advantage plan for 2027.
• Medicare Advantage Open Enrollment: January 1 – March 31. If you are 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.

Every plan can change its formulary, network, and cost-sharing from year to year. Even if you love your current plan, it is worth a quick check during AEP to make sure your drugs are still covered on reasonable terms.

Mistakes to avoid before January

• Skipping the formulary check. The annual cap only applies to drugs your plan covers. Log into medicare.gov and run your drug list through the Plan Finder before you commit.
• Assuming the payment plan is automatic. You have to opt in with your Part D plan. Ask if you think a big bill is coming.
• Confusing Part D with Part B drugs. Infusions and many injectables at the doctor's office are billed under Part B and do not count toward the Part D cap.
• Forgetting IRMAA. Higher-income beneficiaries pay a surcharge on Part D premiums; in 2026, those surcharges start above $109,000 in income for a single filer.
