The two main approaches
| Question | Original Medicare | Medicare Advantage |
|---|---|---|
| How do I get care? | Generally, providers that accept Medicare. | Often through a plan network; check out-of-network rules. |
| Where do prescriptions fit? | Usually through a separate Part D plan. | Most plans include Part D. |
| How are medical costs limited? | No annual out-of-pocket cap without supplemental or other coverage. | An annual limit on covered Medicare health services. |
| What about supplemental coverage? | Medigap may help with certain out-of-pocket costs. | Medigap does not pay Medicare Advantage cost sharing. |
Compare the details you will use
Use each plan’s exact name, identifier and coverage year. Confirm providers, prescriptions, pharmacy choices, service area, premiums, cost sharing and approval requirements. Ask how care works if you travel or live in more than one place.
Keep a written record of questions you have not resolved. A blank space on a comparison sheet should mean “needs an answer,” not “probably fine.”
Put extra benefits in context
Dental, hearing, vision, OTC or food benefits may be useful, but their limits and eligibility can differ. Ask for the benefit terms and avoid combining amounts from different plans.
