Medicare 2026

Before Dec 7: Your Harlingen AEP Checklist

In Harlingen, Medicare's Annual Enrollment Period is open now and runs through December 7. This is the once-a-year window when almost every Medicare beneficiary can change how they get coverage for 2027 — and the choices you make (or skip) this fall will follow you into January.

The Rio Grande Valley has a lot of Medicare-eligible residents, and Harlingen is in Cameron County, where a wide mix of Medicare Advantage and Part D plans are offered each year. Even if you like your current coverage, plans change their drug lists, pharmacy networks, and provider networks every January. AEP is your chance to check the fit before those changes take effect.

What you can actually do during AEP

The Annual Enrollment Period is broader than many people think. Between October 15 and December 7, you can:

• Switch from Original Medicare (Parts A and B) to a Medicare Advantage plan, or the other way around.
• Change from one Medicare Advantage plan to another.
• Join a stand-alone Part D prescription drug plan, switch plans, or drop your drug coverage.

You do not need to prove a life event or qualify for a special situation. If you make more than one change, the last change on file by December 7 is the one that takes effect January 1.

Read your ANOC — then compare

Every fall, your current Medicare Advantage or Part D plan mails an Annual Notice of Change (ANOC). It spells out what will be different in 2027: premiums, cost-sharing, the drug formulary, the pharmacy network, and the provider network.

Read it side-by-side with your prescription list and your doctors. Two questions to ask:

1. Are all my prescriptions still covered, and at what tier? 2. Are my doctors, specialists, and preferred hospitals still in-network in Cameron County in 2027?

If the answers changed, AEP is when to act.

Know the 2027 rules that affect your wallet

A few program-level numbers to keep in mind as you compare:

• $2,400 Part D cap. In 2027, no one on a Medicare drug plan will pay more than $2,400 out-of-pocket for covered prescriptions in the calendar year (up from $2,100 in 2026).
• $700 maximum Part D deductible in 2027. Plans can charge less, but none can charge more (the 2026 ceiling was $615).
• Coverage gap is gone. The old "donut hole" was eliminated in 2025. Part D now has three straightforward phases.
• Medicare Prescription Payment Plan. This optional program lets you spread your yearly drug costs into monthly payments instead of paying a big bill at the pharmacy counter. You have to opt in through your plan.
• IRMAA. Higher-income beneficiaries pay a surcharge on Part B and Part D. For 2026, IRMAA begins above $109,000 in income for a single filer.

How to actually compare plans in Harlingen

The most reliable tool is the Plan Finder at medicare.gov. Enter your ZIP code and your prescription list, and it will show every Medicare Advantage and Part D plan available in Cameron County, along with estimated annual drug costs based on your medications.

A few tips:

• Use your real prescription list, including dosage.
• Add your preferred pharmacy — costs can vary a lot depending on where you fill.
• If you're weighing Medicare Advantage, check that your Harlingen-area providers are listed in the plan's network for 2027, not just today.

Get free, local help — and skip the sales pitch

You don't have to figure this out alone, and you don't have to talk to a salesperson to get answers. Texas offers a free counseling program through the Health Information, Counseling and Advocacy Program (HICAP), which is Texas's State Health Insurance Assistance Program (SHIP). Counselors are trained to explain your options without steering you to a specific plan.

You can also call 1-800-MEDICARE (1-800-633-4227), which is open 24/7.

Be careful with unsolicited calls, door knocks, and texts this time of year. Medicare will not cold-call you to sign you up. If something feels like pressure, hang up.

What if I miss December 7?

For most people, the next chance to change coverage is limited. If you're already in a Medicare Advantage plan, you get one more window — the Medicare Advantage Open Enrollment Period, January 1 through March 31 — to switch to a different Advantage plan or return to Original Medicare (with a stand-alone Part D plan). Outside of those windows, you generally need a Special Enrollment Period tied to a life change, like moving out of your plan's service area.
