Original Medicare pays for much, but not all, of the cost for covered healthcare services and supplies. Medicare Supplement Insurance (Medigap) policies sold by private companies, can help pay some of the remaining health care costs for covered services and supplies, like copayments, coinsurance, and deductibles. Some Medigap policies also offer coverage for services that Original Medicare doesn’t cover, like medical care when you travel outside the U.S. Generally, Medigap doesn’t cover long-term care (like care in a nursing home), vision or dental care, hearing aids, eyeglasses, or private-duty nursing.
Medigap plans are standardized, Medigap must follow federal and state laws designed to protect you, and they must be clearly identified as “Medicare Supplement Insurance.” Insurance companies can sell you only a “standardized” plan, identified in most states as plans A – D, F, G, and K – N. All plans offer the same basic benefits, but some offer additional benefits so you can choose which one meets your needs.
