Medicare Advantage Explained

Medicare Advantage (Part C) is private insurance that bundles your Medicare coverage — and often drug coverage — into one plan. It can lower your monthly cost, but it changes how you get care. Here is the whole picture in plain language.

What Medicare Advantage actually is

Instead of Original Medicare (Parts A and B) paying providers directly, an Advantage plan from a private insurer administers your benefits. Most plans add prescription drugs (Part D) and extras like dental, vision and OTC allowances. You still pay your Part B premium, plus the plan's premium (often $0).

What it really costs

The premium is only part of it. You also pay copays and coinsurance as you use care, up to an annual out-of-pocket maximum (MOOP) that caps your risk. A $0-premium plan with a high MOOP can cost more in a bad year than a pricier plan with a low cap. Model both with the cost calculator and the out-of-pocket maximum calculator.

Advantage vs Original Medicare + Medigap

Advantage trades flexibility for lower upfront cost: networks, referrals and prior authorizations in exchange for a low premium and bundled extras. Original Medicare plus a Medigap policy costs more monthly but lets you see any doctor that takes Medicare with minimal surprise bills.

When you can enroll

Your first window is the 7 months around your 65th birthday. After that, the Annual Election Period (Oct 15–Dec 7) is when most people switch, and current Advantage members get another change in the Jan 1–Mar 31 window. Find your exact dates with the enrollment calculator.

How to choose well

• Check that your doctors and hospitals are in-network.
• Confirm your prescriptions are on the plan's formulary.
• Weigh the out-of-pocket maximum, not just the premium.
• Consider whether you travel — networks are local.
