Medicare Supplement Plans (Medigap)

The best time is during the 6-month Medigap Open Enrollment Period, starting when you're both age 65 and enrolled in Part B. You have guaranteed issue rights — no medical underwriting.

Yes, outside your enrollment period — but insurers may deny coverage or charge higher premiums based on health status.

There are 10 standardized plans labeled A–D, F, G, K–N. Benefits are identical across insurers; only prices vary.

You must be enrolled in Original Medicare (Parts A & B). Some states also allow Medigap for disability or ESRD (End-Stage Renal Disease) recipients under 65.

Coverage varies by plan but often includes: Part A/B coinsurance, hospital deductible, blood transfusions, skilled nursing coinsurance, foreign travel emergencies — some plans even cover Part B excess charges.

No — Medigap policies sold after 2005 don't include drug coverage. You'll need a separate Part D drug plan.

Yes. Medigap allows you to see any doctor or provider who accepts Medicare assignment — giving you nationwide flexibility.

Yes — Medigap is guaranteed renewable for life, as long as premiums are paid. Insurers cannot cancel your policy based on health or claims.

Premiums depend on the insurer and pricing method (community, issue-age, attained-age), plus your location, age, gender, and smoking status.

There are three types of methods used to determine Medigap premiums:

• Community-rated — same for all enrollees
• Issue-age rated — based on your age when you enroll
• Attained-age rated — based on current age, may rise over time

Yes — depends on rating. Attained-age rises with age; community-rated increases with inflation; issue-age stays stable but may adjust due to overall cost changes.

During your Open Enrollment, all conditions are covered. Outside that, insurers may impose waiting periods (usually up to 6 months) or deny coverage based on health history.

Yes, but outside enrollment, you may be subject to underwriting. Some states allow switching on birthday rules or plan discontinuation without underwriting.

If you leave Advantage within 12 months, you have a “trial right” to buy Medigap without underwriting. After that, you'll need to reapply and potentially qualify medically.

Many plans (like C, F, G, and N) include foreign travel emergency coverage, paying up to a specified limit abroad.

Usually, your provider bills Medicare, and Medicare sends the remainder to your Medigap insurer automatically. Some companies may ask you to submit claims directly.

No. Medigap doesn't set an annual cap — instead, it covers cost-sharing per service. This differs from Medicare Advantage, which has an out-of-pocket maximum.

Medigap offers provider freedom and predictable costs, while Advantage includes additional perks but restricts providers and may need referrals. Choice depends on needs and preferences.

Medigap premiums vary by plan letter, carrier, age, gender, tobacco use, and location. Since benefits are standardized within each letter, price differences reflect the carrier's rating method and pricing strategy — not different coverage. A personalized quote is the only accurate way to see what a specific plan letter would cost you.

Guaranteed issue rights allow you to buy certain Medigap plans without health questions if you meet specific events (like leaving a Medicare Advantage plan under a trial right).

Yes — but to use it, you must first leave the Medicare Advantage plan. Medigap won't cover your out-of-pocket costs under Advantage.

Yes. Though covered benefits are standardized, premiums vary by insurer, location, age, gender, and pricing strategy.

Yes — states like Massachusetts, Minnesota, and Wisconsin have additional coverage standards and different rules for Medigap policies.

In most cases, yes. Your Medigap plan stays valid if you move to another state — though your premium amount may change.
