When you become eligible for Medicare, you face a foundational decision: do you enroll in a Medicare Advantage plan (Part C), or do you stick with Original Medicare and add a Medicare Supplement (Medigap) policy? Both paths have real advantages — and real drawbacks. The right answer depends on your health, your budget, your doctors, and how you prefer to manage medical expenses.
Original Medicare + Medigap: Predictability First
Original Medicare covers approximately 80% of your approved medical expenses. The remaining 20% — with no annual cap — is your responsibility. A Medigap policy steps in to cover that gap, and depending on the plan letter you choose, it can cover your 20% coinsurance, Part A and B deductibles, and even foreign travel emergencies.
Pros: No networks. See any doctor or hospital that accepts Medicare anywhere in the country. Your out-of-pocket costs become highly predictable. Plan G, for example, covers virtually everything after the annual Part B deductible.
Cons: Higher monthly premiums. Medigap does not include drug coverage — you'll need a separate Part D plan. In many states, you can only enroll in Medigap without medical underwriting during a limited window (your Initial Enrollment Period or a guaranteed issue situation).
Medicare Advantage: Lower Premiums, More Variables
Medicare Advantage plans are sold by private insurers approved by Medicare. They bundle your Part A, Part B, and usually Part D coverage into one plan. Many plans have $0 or low monthly premiums and offer extra benefits Original Medicare doesn't cover — dental, vision, hearing, gym memberships, over-the-counter allowances, and more.
Pros: Often lower (or zero) monthly premiums. Built-in drug coverage. Extra benefits. An annual out-of-pocket maximum (MOOP) that protects you if you have a catastrophic year.
Cons: Provider networks (HMO or PPO). Prior authorizations for certain services. Benefits, premiums, networks, and formularies change every year. Plans are county-specific, so moving can disrupt your coverage.
The Real Question: What Is Your Risk Tolerance?
Medigap is a high-floor, high-ceiling approach: you pay more every month, but you're protected from large surprises. Medicare Advantage is a low-floor approach: lower premiums, but if you have a serious health event, your out-of-pocket costs can be significant up to your MOOP.
For a healthy 65-year-old with modest drug needs and a preferred network, Medicare Advantage may make excellent financial sense. For someone with chronic conditions, frequent specialist visits, or a preference for provider flexibility, Medigap may offer better protection over time.
