Medicare basics in North Carolina
Medicare is a federal program, so the core rules are the same in North Carolina as everywhere else — but the specific plans available, premiums, and carrier networks vary by ZIP code and county.
Most North Carolina residents become eligible at 65 through Social Security. See eligibility for full rules.
For the 7-month enrollment window timeline, see Turning 65.

North Carolina timing rules
The federal Medigap Open Enrollment window is the same everywhere — 6 months starting the month you turn 65 AND have Part B. During that window, no medical underwriting.
Outside that window, most states (including North Carolina unless otherwise noted) allow Medigap carriers to use medical underwriting. Check North Carolina's State Health Insurance Assistance Program (SHIP) for current state-specific rules.
