What federal rules say
Medicare Advantage plans are governed by federal law, the same in North Carolina as everywhere. Under 42 CFR 422.60, a Medicare Advantage company "must accept without restriction" anyone who is eligible and joins during an allowed period. You're eligible (42 CFR 422.50) if you:
- are entitled to Part A and enrolled in Part B;
- live in the plan's service area, which in North Carolina is set county by county;
- are a U.S. citizen or lawfully present in the United States; and
- agree to follow the plan's rules.
Plans can't ask health questions or turn you down because of a condition, and since 2021 people with end-stage renal disease can join too.
When you can be turned down
- Timing. You must join in a valid period: your Initial Enrollment Period, Open Enrollment (October 15 to December 7, 2026), the January 1 to March 31 Medicare Advantage Open Enrollment Period if you're already in a plan, or a special enrollment period.
- Special needs plans. A D-SNP accepts only people who meet its Medicaid eligibility rules; a C-SNP needs your doctor to confirm a qualifying condition; an I-SNP is for people needing nursing-home-level care. See special needs plans in North Carolina.
- Capacity limits. CMS can let a plan cap enrollment only if members' health and safety are at risk, such as a network that can't serve more people. This is rare.
- One plan at a time. Joining a new Medicare Advantage plan ends your old one.
What it means in North Carolina
Because every North Carolina county has Medicare Advantage plans for 2027 (from 11 in Carteret County to 57 in Guilford), almost everyone with Part A and Part B can join one. The bigger risk runs the other way: if you leave Medigap for Medicare Advantage, North Carolina's Medigap law (G.S. Chapter 58, Article 54) gives you no yearly right to get Medigap back without health questions. Your protections are the 12-month trial right and guaranteed-issue situations, such as a plan ending. See Medigap vs. Medicare Advantage in North Carolina.
If you're a State Health Plan retiree, joining an outside plan moves you off the Plan's group Medicare Advantage plan; see State Health Plan retirees and Medicare. To compare plans from the companies they work with, you can request a call from a licensed insurance agent.

Frequently asked questions
Can I join Medicare Advantage if I have kidney failure (ESRD)?
Yes. Since January 1, 2021, people with end-stage renal disease can join any Medicare Advantage plan they're otherwise eligible for. Before 2021, most couldn't.
Can a Medicare Advantage plan charge me more because of my health?
No. A plan's premium and benefits are the same for everyone enrolled in that plan in a county, and plans can't screen applicants for health conditions.
Why would a Medicare Advantage application be turned down?
Usually because of timing (applying outside an enrollment period), not living in the plan's service area, not having both Part A and Part B, or not meeting a special needs plan's eligibility rules. You can call 1-800-MEDICARE to check.
Can I be denied a Medigap policy in North Carolina?
Yes, outside your Medigap open enrollment period and guaranteed-issue situations. North Carolina has no birthday rule or yearly switching right, so a company can ask health questions and turn you down.
