Medicare Supplement Insurance (Medigap)
How does Medigap work?
Original Medicare pays for much, but not all, of the cost for covered health care 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.
