Turning 65 comes with a stack of Medicare mail and a few decisions that matter for the rest of your life. Here is the plain-English version — what to do, when, and which deadlines you really don’t want to miss — with the Minnesota twists that most guides leave out. When you are ready, we walk through your specific options at no cost.
1. Your enrollment window: the 7-month Initial Enrollment Period
Your Initial Enrollment Period (IEP) is seven months long: the three months before the month you turn 65, your birthday month, and the three months after. Signing up in the three months before your birthday means coverage starts the first of your birthday month. You enroll through Social Security (online at ssa.gov, by phone, or at an office); if you already draw Social Security you are enrolled in A and B automatically.
- Part A (hospital) is premium-free for most people, so most enroll when first eligible.
- Part B (medical) carries the $202.90 standard monthly premium in 2026 — and a timing decision if you are still working (see below).
2. The parts of Medicare, briefly
- Part A — inpatient hospital, skilled nursing, hospice.
- Part B — doctors, outpatient care, preventive services.
- Part C (Medicare Advantage) — a private all-in-one alternative that bundles A, B and usually drug coverage.
- Part D — prescription drug coverage.
- Medicare Cost plans — a Minnesota survival: a network plan at home that falls back on Original Medicare elsewhere, sold in 21 counties.
3. Your big decision: two paths (three, in 21 counties)
| Path | What it looks like |
|---|---|
| Original Medicare + extras | Parts A & B, usually plus a Minnesota Basic or Extended Basic supplement and a standalone Part D plan. Any provider nationwide that accepts Medicare; predictable costs; monthly premiums. |
| Medicare Advantage | A single Part C plan that bundles everything, often $0 premium, with extras like dental and vision — using a local network that changes yearly. |
| Medicare Cost plan (21 counties) | A network plan at home that uses Original Medicare anywhere else; enroll or leave any month. Popular with snowbirds. |
If you lean toward a supplement, there is a second deadline that is easy to miss: your Medigap open enrollment is its own six-month window, separate from the seven-month one above, and it does not repeat. Our research site sets the two side by side for Minnesota — turning 65 in Minnesota.
4. Deadlines that carry lifelong penalties
Part B late penalty. If you don’t enroll in Part B when first eligible (and don’t have qualifying employer coverage), a permanent penalty of 10% per 12 months is added to your premium for life.
Part D late penalty. Going 63+ days without creditable drug coverage can add a permanent surcharge to your Part D premium.
Medigap open enrollment. Your six-month Medigap open enrollment begins when you are 65 and enrolled in Part B — during it Minnesota guarantees you the Basic and Extended Basic plans without medical underwriting. Under a law effective August 1, 2026, Minnesota also gives people aged 65 through 70 a one-time chance to buy a supplement without underwriting during the Annual Election Period or the Medicare Advantage Open Enrollment Period, with a premium surcharge of 15% to 35% that lasts as long as the policy; it is a safety net, not a substitute for using the first window well.
5. Still working at 65?
If you (or your spouse) have qualifying employer coverage, you may be able to delay Part B without penalty and get a Special Enrollment Period when that coverage ends. The rules depend on employer size (20 or more employees is the usual line) and whether the drug coverage is creditable. Minnesota’s big employers — the state, the university, the health systems, 3M, Target — generally qualify; a small business or a retiree plan may not. It is worth a quick conversation before you decide, and a form (CMS-L564) from your employer when you do enroll.
6. A simple checklist
- Mark your 7-month IEP on the calendar (it starts 3 months before your birthday month).
- Decide on Part B based on whether you have other creditable coverage.
- Find out whether your county is one of the 21 Cost-plan counties.
- Choose your path: Original Medicare + supplement + Part D, Medicare Advantage, or a Cost plan.
- Check that your doctors and prescriptions are covered before you enroll — especially if Mayo Clinic is in the picture.
- If you winter away, read the snowbird guide first; if you are a veteran, see how TRICARE or VA benefits coordinate; if you have Medical Assistance, see MSHO.
- Estimate your costs on our 2026 costs & IRMAA page.

Frequently asked questions
When should I sign up for Medicare if I’m turning 65?
During your Initial Enrollment Period — the seven months that span the three months before your birthday month, your birthday month, and the three months after. Signing up in the first three months means coverage starts on the first of your birthday month.
Do I have to take Part B at 65 if I’m still working?
Not always. If you have qualifying employer coverage (generally from an employer with 20 or more employees), you may delay Part B without penalty and get a Special Enrollment Period later. The rules depend on the employer’s size, so confirm before you decide.
Is it better to get Medicare Advantage or Original Medicare with a supplement in Minnesota?
Neither is automatically better — it depends on your doctors, prescriptions, travel and budget, and in 21 counties a Cost plan is a third choice. We compare them with you so the choice fits your life.
What is different about turning 65 in Minnesota?
Your supplement choices are Basic and Extended Basic rather than the lettered plans, Cost plans still exist in 21 counties, and if you later regret an Advantage choice, a 2025 state law (effective August 1, 2026) gives people aged 65 through 70 a one-time chance to buy a supplement without health questions during the Annual Election Period or the Medicare Advantage Open Enrollment Period, with a lasting surcharge of 15% to 35%.
