Understand Medicare
before you decide.
A clear, no-jargon guide to how Medicare works — the parts, the costs, the deadlines, and the decisions that matter most.
Are you eligible for Medicare?
Answer a few quick questions to find out your eligibility status and what steps to take next.
How old are you?
Your age determines when you first become eligible for Medicare.
Do you currently have health coverage?
This affects when you need to enroll and whether late penalties could apply.
Are you (or your spouse) still working?
This determines whether you can delay Medicare enrollment without penalty.
The four Parts of Medicare.
Medicare isn't one thing — it's a system of parts, some public and some private, that you assemble into coverage that fits your life.
Hospital InsuranceCovers inpatient hospital care, skilled nursing facilities, hospice, and some home health services. — When you're admitted

Medical InsuranceCovers doctor visits, outpatient care, preventive services, lab work, and durable medical equipment. — When you see a doctor
Covers everything outpatient — doctor visits, preventive care, lab work, outpatient surgery, and durable medical equipment. Monthly premium of $202.90 in 2026 (higher earners pay more). You pay 20% of approved services with no cap — that's why most people pair it with MedigapMedicare Supplement plans that fill the 'gaps' in Original Medicare, such as the 20% coinsurance. Standardized into lettered plans (G, N, etc.).. Late-enrollment penalty: 10% added to your premium for every 12 months you were eligible but didn't sign up — for life.
Medicare AdvantagePrivate plans (Part C) that deliver your Part A and Part B benefits — plus usually Part D — through one plan with a provider network. — All-in-one, private

PPO = Preferred Provider Organization (can go out-of-network at higher cost).) with a yearly out-of-pocket maximumThe most you'd pay out-of-pocket in a year for covered services. Original Medicare has NO annual cap — that's a key difference. required by law. You must be enrolled in Parts A and B first.

When to enroll.
Medicare has more enrollment periods than most people expect. Missing the right one can mean lifetime penalties.
Initial Enrollment Period
A 7-month window: 3 months before your 65th birthday month, the birthday month itself, and 3 months after. Enroll in the first 3 months so coverage starts on day one.
General Enrollment Period
Your backup if you missed your IEP. Covers Part A and/or Part B enrollment only (not plan switching). Coverage starts the month after you enroll. Late penalties may apply.
Special Enrollment Period
Triggered when you leave employer coverage past 65. You get up to 8 months for Part B penalty-free, but only 63 days for Part D. Don't miss the Part D window.
Annual Enrollment Period
Every fall, switch MA plans, change Part D, or move between Original Medicare and Advantage. Changes take effect January 1. Review your plan every year.
Medicare Advantage Open Enrollment
If you're already in MA, you get one chance to switch to a different MA plan or return to Original Medicare + standalone Part D.
Your Initial Enrollment Period (IEP)
A 7-month window centered on the month you turn 65.
Late-enrollment penalties.
Miss your enrollment window without creditable coverage, and Medicare will charge you extra — often for the rest of your life. Use the sliders below to see how penalties add up.
If you enroll late without creditable coverageCoverage from an employer with 20+ employees that's considered at least as good as Medicare. If you have this, you can delay without penalty.
The penalty is added to your Part B premium for as long as you have Part B — for most people, that means for life. It's based on the standard premium ($202.90/mo in 2026).
If you go 63+ days without creditable drug coverage
The 2026 national base beneficiary premium is $36.78/mo. The penalty is added to your Part D premium for as long as you have Part D. It's small per month but compounds fast.
