Medigap insurance in North Carolina, explained
Medicare Supplement Insurance — usually called Medigap — is private insurance that fills the cost-sharing gaps in Original Medicare (Parts A and B). Without a Medigap policy, Original Medicare leaves you exposed to deductibles, 20% coinsurance with no out-of-pocket maximum, and other charges that can add up fast on a serious hospital stay or chronic condition.
With Medigap, you get the best of both worlds: any-doctor-anywhere access from Original Medicare combined with predictable, capped out-of-pocket costs from your Medigap plan. No referrals. No prior authorizations. No network restrictions.
The key Medigap distinction
Medigap supplements work only with Original Medicare. You cannot have a Medigap plan and a Medicare Advantage plan at the same time. The choice between Medigap and Medicare Advantage is the biggest fork in your Medicare planning.
Standardized Medigap plans
Medigap plans are standardized by the federal government, which means a "Plan G" from one carrier covers exactly the same things as "Plan G" from another carrier. The only differences between carriers are the price, customer service, and rate stability.
| Plan | What it covers | Best for |
|---|---|---|
| Plan G | Almost everything except the small annual Part B deductible ($257 in 2026). Most popular Medigap plan in NC. | Most clients — predictable costs, comprehensive coverage |
| Plan N | Like Plan G but with small office-visit copays ($20 doctor / $50 ER if not admitted) and you pay the Part B deductible. Lower premium than G. | People who want lower monthly premiums and don't mind small copays |
| High-Deductible Plan G (HDG) | Plan G but you pay the first $2,870 of out-of-pocket costs (2026 deductible) before the plan kicks in. Much lower premium. | Healthy people who rarely use medical care and want catastrophic-only protection |
| Plan A, B, D, K, L, M | Various lesser-coverage plans. Less common in NC for new enrollees. | Specific situations only — usually we recommend G or N |
| Plan F | Was the most popular plan, covers everything including the Part B deductible. Only available to people who became Medicare-eligible before January 1, 2020. | Existing Plan F enrollees who can keep it |
For people newly eligible for Medicare in NC: it's almost always Plan G or Plan N. The other plans either offer worse value or aren't available to new enrollees.
Medigap pricing in North Carolina
Carriers can price Medigap policies three different ways. NC allows all three.
Issue-age rated
Premium based on your age when you bought the policy. Increases over time only with inflation, not your age. Generally the best long-term value.
Attained-age rated
Premium based on your current age and goes up each year as you get older. Usually the cheapest at younger ages but most expensive long-term.
Community-rated
Same premium for everyone regardless of age (though some adjustments for tobacco use). Less common in NC.
We always look at the rate history of a carrier, not just the current premium. A carrier that's been raising rates 8% per year for 5 years is a worse deal than one that's been raising 3% per year, even if today's premium is similar. This is one of the most overlooked parts of Medigap shopping — and where independent agent comparisons really matter.
Top Medigap carriers in North Carolina

When you can buy Medigap (this is critical)
Medigap Open Enrollment Period — the only "guaranteed issue" window
The 6-month period that begins on the first day of the month you're 65 AND enrolled in Part B. During this window:
- You can buy any Medigap plan from any carrier in NC
- You cannot be denied for pre-existing conditions
- You cannot be charged more for health reasons
Outside the Open Enrollment Period
You can apply for Medigap any time, but you'll typically need to medically underwrite — the carrier reviews your health and can deny you or charge more. There are some exceptions called "guaranteed issue rights" (e.g., if your Medicare Advantage plan terminates, or you move out of its service area within the first year).
This is the single most important Medigap rule
Buy your Medigap policy during your 6-month Open Enrollment window. After that, your right to buy any plan you want without health questions is gone. We'll help you time everything correctly.
Medigap vs. Medicare Advantage — how to choose
The high-level trade-off:
- Medigap: Higher monthly premium ($90–$200+/mo in NC). Any doctor in the country who accepts Medicare. No referrals. No prior auth. Add separate Part D for drugs and stand-alone dental/vision.
- Medicare Advantage: Often $0 premium. Network-based. Drug coverage, dental, vision, fitness usually bundled. Referrals and prior auth often required.
For people who travel, see specialists at academic medical centers, or want the most predictable healthcare experience, Medigap usually wins. For people who stay in NC, are comfortable with networks, and value extras, Medicare Advantage often wins. We compare both paths for every client.

Frequently asked questions
What's the difference between Medicare Supplement and Medicare Advantage?
Medicare Supplement (Medigap) works WITH Original Medicare to fill cost-sharing gaps — you keep Medicare's any-doctor freedom and add predictability. Medicare Advantage REPLACES Original Medicare with a private plan that uses networks. You can have one or the other, not both.
Which Medigap plan is best?
For most newly eligible NC clients, Plan G is the most popular and offers the best balance of comprehensive coverage and reasonable premium. Plan N is the second-most-popular and runs a bit cheaper with small office-visit copays. We pick based on your specific budget and health usage.
How much does Medigap cost in North Carolina?
For Plan G in NC, premiums typically run $100–$200/month for a 65-year-old non-smoker, depending on the carrier and your ZIP code. Plan N usually runs $20–40/month less. High-Deductible Plan G can be as low as $40–60/month. Premiums increase with age (on attained-age plans) or with inflation only (on issue-age and community-rated plans).
Can I be denied Medigap?
Not during your 6-month Medigap Open Enrollment Period (the 6 months starting when you're 65 AND on Part B). Outside that window, in most cases yes — carriers can deny or charge more based on health, except in specific 'guaranteed issue' situations.
Can I switch Medigap plans later?
Yes, but you typically need to medically qualify for the new plan. If you're healthy, switching to a lower-premium carrier with the same plan letter (e.g., Plan G to Plan G) is a common way to save money. We help clients shop their Medigap every 1–3 years to keep premiums in check.
Does Medigap include drug coverage?
No. Medigap plans don't cover prescriptions. You'd add a stand-alone Part D plan for drugs. (This is a key difference from Medicare Advantage, which usually bundles drug coverage in.)
Does my Medigap plan travel with me?
Yes — that's one of the best parts. Medigap covers any doctor or hospital in the U.S. that accepts Medicare. Some plans even include limited foreign travel emergency coverage.
Can I have Medigap if I'm under 65 on Medicare due to disability?
It depends. Federal law doesn't require carriers to issue Medigap to under-65 disabled enrollees, but many states require it. North Carolina law allows but doesn't require carriers to offer Medigap to under-65 enrollees, and the limited plans available are often expensive. We help under-65 clients navigate this carefully.
