If you're turning 65 in Austin, your most important Medicare decisions happen inside a single 7-month window — and the choices you make now are hard to undo later. This roadmap walks you through that timeline, the four parts of Medicare, how to read the Austin-area plan landscape, and the one local question that decides more than any premium.

Every figure below comes from public sources — Medicare.gov, the Medicare Plan Finder, and CMS 2026 cost rules. No invented numbers, no "call for pricing."

Step 1: Know your 7-month window

Your Initial Enrollment Period (IEP) is built around your 65th birthday. When you act inside it changes when your coverage starts:

The takeaway: the first 3 months are the sweet spot. Enroll then and your coverage begins the first day of your birthday month with no gap. Wait until after the window closes and — unless you qualify for a Special Enrollment Period because you kept working with employer coverage — you can face Part B and Part D late penalties that last for life. You enroll in Parts A and B through Social Security.

Step 2: Understand the four parts

"Medicare" is really four pieces, and turning 65 means deciding how to assemble them:

• Part A (hospital) — premium-free for most people who worked 10+ years. Almost everyone takes it at 65.
• Part B (medical) — carries a monthly premium set by CMS each year; higher earners pay an IRMAA surcharge. Delaying it without other creditable coverage triggers a lifelong penalty.
• Part C (Medicare Advantage) — a private bundle of A + B (usually + drugs) with a network and a yearly out-of-pocket cap.
• Part D (drugs) — prescription coverage, either inside an Advantage plan or stand-alone alongside Original Medicare + a Medigap supplement.

The real fork at 65 is Medicare Advantage vs. Original Medicare + a Medigap supplement + Part D. And there's a clock on it: your turning-65 window is the one time you can buy Medigap with guaranteed issue in most cases — no medical underwriting. That one-time right is why this decision deserves real attention now, not later.

Step 3: Read the Austin plan landscape

The Austin metro is one of the most competitive Medicare Advantage markets in Texas. Travis, Williamson, and Hays counties together offer dozens of Part C plans — many at a $0 premium — plus stand-alone Part D drug plans and Medigap supplements sold separately. That sounds like good news, and it is, but volume is also the trap: a $0 premium tells you nothing about whether your doctors and your drugs are covered.

The smart move is to narrow the list with three filters, in this order:

1. Network — does the plan include your primary-care doctor, your specialists, and your hospital? (More on the three Austin systems below.)
2. Formulary — are your exact prescriptions on the plan's drug list, and at what tier?
3. Total cost — premium plus deductibles, copays, and the plan's out-of-pocket maximum — not the premium alone.

Run your ZIP through the official Medicare Plan Finder or use the live tool below to see what's available where you live.

Step 4: Do the 2026 cost math

The most common new-to-Medicare mistake is choosing on premium alone. A $0 premium covers exactly one thing — the monthly fee. Here's the 2026 framework that actually matters:

The genuinely good 2026 news: the Part D out-of-pocket maximum is now $2,100, so no matter which plan you choose, your annual drug spending is capped. That shifts the smart comparison toward the formulary tier of your specific drugs and the plan's out-of-pocket maximum — not the premium in isolation. See current drug-cost rules at Medicare.gov — Drug coverage (Part D) costs.

Step 5: Settle the network question

This is the local decision that quietly drives everything. Austin care runs through three competing systems, and your plan's network is the bridge to them:

If your doctors are concentrated in one system, the plans that include that system jump to the top of your list — and the rest fall away no matter how attractive the premium. Confirming your specific physicians and hospital are in-network for 2026 is the non-negotiable step before you enroll.

Step 6: Match the plan to your local health picture

Austin is a big, mostly young market — but the people aging into Medicare carry the chronic-condition load that decides which coverage actually pays off. Here is the Travis County picture by the numbers:

Premium and network only get you halfway — coverage of your conditions and medications decides the rest. CDC data shows the real chronic-condition load among Travis County adults:

If you manage high blood pressure (about 28% of local adults), diabetes, or arthritis, the plan's drug formulary and specialist network matter far more than its premium. And with medical-care prices still rising +2.16% a year, the 2026 $2,100 Part D cap is doing real work to protect your downside. Bring your exact medication list when you compare.

What to watch as you approach 65 in 2026

1. Mark your 7-month window on a calendar — and aim to enroll in the first 3 months.
2. Decide Advantage vs. Medigap early, while your one-time guaranteed-issue Medigap right is active.
3. Confirm your system — Ascension Seton, St. David's, or Baylor Scott & White — and your specific doctors are in any plan's 2026 network.
4. Run your real drug list against each plan's formulary; weigh the deductible and the $2,100 cap, not just the premium.
5. If you're still working at 65, check whether a Special Enrollment Period lets you delay Part B penalty-free.
