After you have Medicare Parts A and B, most people choose how to handle the costs Original Medicare does not cover. There are two common structures.
Path A
Original Medicare + Medigap + Part D
- See any provider who accepts Medicare, in most cases
- Medigap helps with deductibles and coinsurance
- Prescriptions usually need a separate Part D plan
- Monthly cost is often higher; bills are more predictable
Path B
Medicare Advantage (Part C)
- Private plan that delivers Medicare benefits
- Usually includes Part D and extra benefits
- Typically uses a network and plan rules
- Premium may be low; you still pay the Part B premium
Five questions to guide your comparison
- Which doctors and hospitals do you want to keep? Check participation in the exact Medicare Advantage plan, or confirm that your providers accept Original Medicare if you are considering Medigap.
- Do you travel or split time between states? Networks can be local. Original Medicare + Medigap often travels more easily.
- How do you prefer to manage out-of-pocket costs? Advantage uses copays and an annual maximum. Medigap is designed to make Original Medicare’s 20% more predictable.
- What prescriptions do you take? Check the formulary and pharmacy network either inside Advantage or on a standalone Part D plan.
- Could you need to switch later? Switching from Medicare Advantage to Medigap may require medical underwriting outside protected enrollment opportunities. Review your switching rights before choosing coverage.
