Medicare Supplement (Medigap)

Medicare Supplement Insurance (also called Medigap) is optional coverage sold by private insurance companies that helps pay some of the costs Original Medicare doesn’t—like copayments, coinsurance, and certain deductibles. Medigap works only with Original Medicare (Part A and Part B), and it can make your healthcare expenses easier to budget because it helps reduce what you pay when you receive care.
Medigap plans come in different standardized options (often labeled by letters), pricing can vary by company, and your ability to enroll may depend on timing, especially around your initial Medigap enrollment window. Choosing the right plan means balancing monthly premium vs. out-of-pocket risk, and making sure the plan fits your doctors, travel needs, and long-term budget.
