Medicare Advantage vs Original Medicare

Two ways to get your Medicare. Here is how they compare in 2026 — costs, flexibility, and the trade-offs.

Compare coverage routes using your care needs

Can a plan’s premium tell me which route is better?

A premium alone does not answer that question. Review access to providers, drugs, cost sharing and plan rules. Use the official side-by-side explanation to understand the route, then the actual plan documents to compare your care.

Is Medigap another name for Medicare Advantage?

No. Medigap is supplemental insurance used with Original Medicare; it is not a Medicare Advantage plan. Before switching coverage, check the official Medigap purchase rules and whether you have rights to buy the policy you want.

What should I check for my doctor and medicines?

Confirm provider participation and pharmacy and drug coverage using current official plan information. A provider list or drug formulary can change. Keep the plan name and coverage year attached to any notes you use.

Can this site recommend a particular plan?

This site supplies educational comparisons, not licensed insurance advice or plan enrollment. Use Medicare Plan Finder and qualified help for your own circumstances. The most useful comparison records actual services and coverage restrictions rather than a generic claim that one route is best.

Original Medicare (Parts A + B)

The government program. See any doctor that accepts Medicare nationwide, no networks. You typically add a standalone Part D drug plan and often a Medigap supplement to cover out-of-pocket costs. You pay the $202.90 Part B premium (2026) plus any IRMAA.

Medicare Advantage (Part C)

A private plan that bundles A, B, and usually D, often with $0 premium and extras like dental, vision, and hearing. The trade-off: provider networks and referrals, and care is managed by the plan. You still pay your Part B premium.

Switching between them

You can move between Advantage and Original Medicare during the Annual Enrollment Period (Oct 15 – Dec 7) or the Medicare Advantage Open Enrollment Period (Jan 1 – Mar 31). Note that going back to Original Medicare with a Medigap plan can require medical underwriting outside your first enrollment.

Frequently asked questions

Is Medicare Advantage cheaper than Original Medicare?

Advantage plans often have lower or $0 premiums and bundle drug coverage, but use networks and can have higher costs when you need a lot of care. Original Medicare plus Medigap costs more monthly but offers nationwide access and predictable costs.

Can I switch from Medicare Advantage back to Original Medicare?

Yes, during the Annual Enrollment Period (Oct 15-Dec 7) or the Medicare Advantage Open Enrollment Period (Jan 1-Mar 31). Adding a Medigap plan later may require underwriting.

Does Medicare Advantage include drug coverage?

Most Medicare Advantage plans include Part D prescription drug coverage, but not all — always check the specific plan.
