Medicare in 10 Minutes
Parts A, B, C, D — what each actually does and what it costs.
Parts A, B, C, D — what each actually does and what it costs.
Part A — Hospital
Covers inpatient hospital, skilled nursing, hospice. Free for most people who paid Medicare taxes 10+ years. Deductible per benefit period, not per year.
Part B — Medical
Covers doctors, outpatient care, preventive services. Standard 2026 premium: $202.90/month, higher based on income (IRMAA). Annual deductible $283, then Medicare pays 80%.
Part C — Advantage
Private plan that replaces A + B (often includes D). Lower monthly premium, but network restrictions and prior authorizations. Not the same as Original Medicare + Medigap.
Part D — Prescription drugs
Standalone drug plan. Premiums vary by plan. In 2026, annual out-of-pocket drug costs are capped at $2,100 (up from $2,000 in 2025) — a huge change from pre-2025 years when there was no cap.
Medigap (Supplement)
Fills gaps in Original Medicare (the 20% not covered by Part B). Higher monthly premium, but predictable costs and no networks. Best time to buy: your 6-month open enrollment window at 65.
The choice between Advantage and Original + Medigap is the biggest Medicare decision you'll make — and switching later is often not possible without underwriting.
