Medicare, explained clearly.

Your Initial Enrollment Period lasts 7 months: the 3 months before your 65th-birthday month, your birthday month, and the 3 months after. Enrolling on time helps you avoid lifetime late-enrollment penalties on Part B and Part D.

The big decision is between two paths: Original Medicare + a Supplement + Part D, or a Medicare Advantage plan. There's no universal right answer — it depends on your doctors, medications, budget, and travel.

✓ Your checklist

1. 3–4 months before your birthday, confirm your Part A/B enrollment — automatic if you already receive Social Security; otherwise apply at ssa.gov or 1-800-772-1213.
2. Write down your doctors, medications with doses, and preferred pharmacy.
3. Compare both paths against that list — never choose on premium alone.
4. Still working with employer coverage? Ask your benefits office how it coordinates with Medicare before declining Part B.
5. Enroll before your 7-month window closes.

Medicare Advantage (Part C) bundles your benefits through a private carrier — usually with drug coverage, often with extras like dental, vision, OTC, or transportation on some plans — in exchange for a network and plan rules. Benefits vary by plan, county, and eligibility.

Medicare Supplement (Medigap) works with Original Medicare to pay your share of costs, lets you see any doctor in the U.S. who accepts Medicare, and pairs with a separate Part D plan — typically at a higher monthly premium.

✓ Your checklist

1. List what matters most: lowest premium? any-doctor freedom? predictable costs? extra benefits?
2. For Advantage: verify every doctor in-network, your drugs on the formulary, and the max out-of-pocket.
3. For Supplement: compare plans G and N across companies, and apply in your 6-month Medigap open enrollment for guaranteed acceptance.
4. Re-check your choice every fall — plans change each January 1.

Every Part D plan has its own covered-drug list (formulary), tiers, and pharmacy network. The plan with the lowest premium is frequently not the cheapest once your actual prescriptions are priced.

✓ Your checklist

1. List every medication, dose, and frequency.
2. Compare plans by total yearly cost — premium + deductible + copays — using Medicare.gov's Plan Finder or a licensed advisor.
3. Confirm your pharmacy is in-network; 'preferred' pharmacies often cost less.
4. Enroll when first eligible — 63+ days without creditable drug coverage can mean a permanent late penalty.
