Can Medicare Advantage plans deny coverage for pre-existing conditions?

Answered by 10 licensed agents

Short answer: no. Medicare Advantage plans are guaranteed issue. If you have Part A and Part B, live in the plan's service area, and enroll during a valid enrollment period, the plan has to take you — no health questions, no medical underwriting, no rate-ups for your history. That's been true across the board since 2021, when even the old End-Stage Renal Disease exclusion was removed. There is no health condition that can keep you out of a Medicare Advantage plan.

I think this question comes up so often because people are remembering how health insurance worked before 65, or they're mixing up two different products. The place pre-existing conditions do matter in Medicare is Medigap (Medicare Supplement). Outside your one-time six-month Medigap Open Enrollment window — and outside a handful of guaranteed-issue situations — Medigap carriers in most states can ask health questions and decline you based on your answers.

That distinction is worth sitting with, because it cuts both ways. Your health history can't keep you out of Medicare Advantage today — but if you join an Advantage plan and later decide you want to switch to Original Medicare with a Medigap policy, that's the move where your health may be underwritten. A lot of people don't learn this until they're trying to make that switch.

One more thing people confuse with a "denial": an Advantage plan can never deny you enrollment for a condition, but it can require prior authorization for specific treatments once you're a member. That's a coverage-management issue, not a pre-existing condition exclusion — and you have appeal rights when it happens.

If you're weighing Advantage vs. Medigap right now and you have health history, the order you make decisions in matters. A local independent agent can walk you through which doors stay open and which ones may close.

Medicare Advantage plans generally cannot deny enrollment or coverage because of pre-existing conditions. As long as you're eligible for Medicare and enroll during a valid enrollment period, the plan must accept you, with only a few limited exceptions such as End-Stage Renal Disease rules that have largely been eliminated in recent years.

No Medicare Advantage plans will not deny coverage for pre-existing conditions. There are certain Medicare advantage plans called CSNP plans Chronic Special needs plans where you have to have a pre existing condition to join these plans. Medicare Supplement plans can deny for the pre existing conditions though.

No, Medicare Advantage plans cannot deny your enrollment nor limit your coverage based on preexisting conditions. By law, private insurance companies must accept any application as long as the person is eligible and has a valid enrollment period.
