Turning 65: Your Medicare Step-by-Step
Turning 65 is when Medicare starts — and the choices you make now are some of the hardest to undo. This is the whole journey in 10 steps: when your window opens, whether to delay for employer coverage, how to sign up, the big Medigap-vs-Advantage decision, drug coverage, and what it all costs. Work through it here, or let us walk you through it free.
"I'm turning 65 — what do I actually do?" Here's the whole thing, in order. Each step links to a deeper guide or a calculator, and you can hand any of it to us to do together, free.
Your Step-by-Step Timeline
-
3 months before your 65th-birthday month
Your enrollment window opens
Your Initial Enrollment Period (IEP) is a 7-month window — the 3 months before your birthday month, the month itself, and the 3 months after. Signing up in the first 3 months gets your coverage started the soonest.

What’s next: Before you enroll, check your employer coverage (next).
-
Before you enroll
Check your employer coverage
If you (or your spouse) still have active, creditable employer coverage, you may be able to delay Part B without a penalty and get a Special Enrollment Period later. If you don’t, enroll on time to avoid permanent penalties. Retiree and COBRA coverage usually do NOT count — check before you delay.
Special Enrollment Period & creditable coverage →
What’s next: Decide whether to enroll now or delay — then sign up for Part A & B.
-
During your IEP
Sign up for Part A and Part B
Enroll through Social Security (online, by phone, or in person). Part A is usually premium-free; Part B has a monthly premium. This is your foundation — everything else builds on it.
What’s next: Now choose how to cover Original Medicare’s gaps.
-
The big decision
Choose your path: Medigap or Medicare Advantage
Original Medicare alone has gaps (no drug coverage, no out-of-pocket cap). You fill them one of two ways: Original Medicare + a Medigap policy + a Part D plan, or an all-in-one Medicare Advantage plan. This is the most consequential choice — and the hardest to reverse later.

What’s next: If you lean Medigap → step 6. If you lean Advantage → step 7.
-
If you choose Medigap
Pick a Medigap plan while you have guaranteed issue
Your 6-month Medigap Open Enrollment starts when your Part B does — during it, insurers can’t deny you or charge more for health reasons. It’s the best time to lock in Plan G or Plan N. Miss it and Utah generally allows medical underwriting.
Plan G vs Plan N → · estimate Medigap costs
What’s next: Add a Part D drug plan (step 8).
-
If you choose Medicare Advantage
Compare Medicare Advantage plans
Advantage plans bundle everything (usually including drugs) and cap your yearly out-of-pocket, often for a $0 premium — but they use networks. Verify your doctors, hospital, and pharmacy are in-network before you enroll, especially in the rural Basin.

What’s next: Advantage usually includes drug coverage — but confirm it covers your meds (step 8).
-
Everyone taking medications
Get Part D drug coverage that fits your prescriptions
With Medigap you add a standalone Part D plan; with Advantage it’s usually built in. Either way, the cheapest premium is rarely the cheapest plan — match the formulary and preferred pharmacy to your exact medication list.
What’s next: Now put real numbers to it.
-
Know your numbers
Estimate your costs — and check IRMAA
Add up your Part B premium, any Part D and supplement premiums, and expected out-of-pocket. Higher earners also pay an income surcharge (IRMAA) on Part B and Part D — worth checking before you finalize.
Medicare costs → · run the cost estimator
What’s next: You’re set — coverage begins on schedule.
-
Your birthday month
Coverage begins
If you signed up during the 3 months before your birthday month, coverage starts the 1st of your birthday month. Keep your Medicare card and plan materials handy, and confirm your doctors and pharmacy have your new info.
What’s next: Then review your plan every year.
-
Every year after
Review at Annual Enrollment (Oct 15 – Dec 7)
Plans change their formularies, premiums, and networks every year — so the plan that fit you at 65 may not fit you at 66. A free yearly review during AEP keeps you in the best plan for your current doctors and medications.
What’s next: That’s the whole journey — and we’re here for all of it.
