Original Medicare vs Medicare Advantage
Original Medicare (Parts A & B) and Medicare Advantage (Part C) solve the same problem in different ways. Original Medicare is the federal health program for people 65+ and certain younger people with disabilities. Part A covers hospital stays (usually premium-free if you paid Medicare taxes long enough) and Part B covers outpatient and physician care for a monthly premium. It has no network — most U.S. doctors accept it — but it has no out-of-pocket maximum on its own, which is why many beneficiaries add a Medigap policy and a Part D drug plan. By contrast, Medicare Advantage plans are offered by private insurers approved by Medicare and bundle Part A, Part B, and usually Part D, often adding dental, vision, hearing, and fitness perks. Premiums can be as low as $0 on top of Part B, and every plan has an annual out-of-pocket maximum. The trade-off is provider networks and prior-authorization rules, so plan choice hinges on whether your doctors are in-network and how your prescriptions are covered. Below we compare them on cost, coverage, eligibility, and who each one fits best — with sources you can check.

|---|---|---|
| Typical monthly cost | Part B approx. $185/mo (2025 standard; higher for high incomes); Part A usually $0 | Approx. $0-$100/mo plan premium on top of the Part B premium |
