Glendale Medicare Checklist: 5 Moves to Make by Dec. 7

GLENDALE, Ariz. — The clock is ticking on Medicare's Annual Enrollment Period. Between now and December 7, people with Medicare in Glendale can change how they get their coverage for 2027 — and the choices they make (or skip) will lock in for the whole year. With the Part D out-of-pocket drug cap rising to $2,400 in 2027 and plans mailing out updated benefit notices, this is the window to look before you leap.

Key takeaways

  • The Annual Enrollment Period runs **October 15 through December 7**, and changes you make take effect January 1, 2027.
  • In 2027, Part D out-of-pocket drug spending is capped at **$2,400**, and the Part D deductible can be no more than **$700**.
  • You can switch between Original Medicare and Medicare Advantage, change Part D drug plans, or join a plan for the first time during AEP.
  • Glendale is in Maricopa County, where plan availability is set at the county level — so compare options using your ZIP code on medicare.gov.

What you can actually do during AEP

The Annual Enrollment Period is the one window each fall when almost anyone with Medicare can make a change. During AEP you can:

Whatever you choose by December 7 starts on January 1, 2027.

Why this year deserves a fresh look

Even if you're happy with your current coverage, 2026 brings real changes worth checking:

Your current plan also sends an Annual Notice of Change (ANOC) each fall. Read it. Premiums, drug formularies, provider networks, and copays can all shift year to year.

A simple checklist for Glendale residents

1. Pull out your ANOC and Evidence of Coverage. Check what's different for 2026. 2. List your prescriptions and doctors. Include dosages — formularies change. 3. Confirm your providers. If you're in a Medicare Advantage plan, make sure your Glendale-area doctors and hospitals are still in-network for 2026. 4. Use the Plan Finder. At medicare.gov, enter your Glendale ZIP code to see plans available in Maricopa County. 5. Check income-related surcharges. If your 2024 income was above $109,000 (single filer), IRMAA surcharges may apply to Parts B and D in 2026.

What happens if you do nothing

If you take no action by December 7, you'll generally stay in your current plan for 2027 — with whatever changes your plan has made. That's fine if the plan still fits. It's a problem if your drugs were dropped from the formulary or your doctor left the network.

One more date to know: the Medicare Advantage Open Enrollment Period runs January 1 through March 31. If you're already in a Medicare Advantage plan, you get one chance during that window to switch to a different Advantage plan or return to Original Medicare. It's a safety net — not a substitute for using AEP well.

Frequently asked questions

What is the deadline for Medicare's Annual Enrollment Period?
The Annual Enrollment Period ends December 7. Any changes you make between October 15 and December 7 take effect on January 1 of the following year.
Can I change my Medicare Advantage plan after December 7?
Yes, but your options narrow. From January 1 through March 31, the Medicare Advantage Open Enrollment Period lets people already in a Medicare Advantage plan switch to another Advantage plan or go back to Original Medicare (with a stand-alone Part D plan if needed). You cannot use this window to switch from Original Medicare into a Medicare Advantage plan.
Do I have to do anything during AEP if I like my current plan?
No. If you take no action, you'll generally stay in your current plan. But your plan's costs, drug list, and network can change for 2027, so it's smart to read your Annual Notice of Change before deciding to stay put.
Where can I get help comparing plans in Glendale?
Start at medicare.gov and use the Plan Finder with your Glendale ZIP code — plans are set at the Maricopa County level. You can also call 1-800-MEDICARE anytime or contact Arizona's SHIP for free one-on-one counseling.
