Original Medicare vs. Medicare Advantage: How to Choose

Start with the way you want to receive care, then compare plans. Premiums alone do not reveal the best fit.

Original Medicare

You can generally use any provider in the United States that accepts Medicare. Specialist referrals and prior authorization are less common. You may add Part D and Medigap. Without supplemental coverage, there is no annual limit on what you pay for covered Part A and B services.

Medicare Advantage

A private plan provides Part A and Part B benefits, usually with Part D. Plans have an annual out-of-pocket limit for covered Part A and B services and may add dental, vision, hearing or fitness benefits. Networks, service areas, referrals and prior authorization may apply.

Compare these eight items

1. Your doctors and hospitals.
2. Every prescription and dosage.
3. Monthly premiums.
4. Normal-year copays.
5. The in-network and out-of-network maximum.
6. Prior-authorization and referral rules.
7. Travel or seasonal residence needs.
8. How easy it would be to obtain Medigap later in your state.
