These are called Medicare Gaps, and private insurance companies offer Medicare Supplement (Medigap) policies that pay for these benefit gaps in Medicare Part A and Part B plans. Medigap helps you pay the deductible, co-insurance, and co-pay, as well as additional charges not covered by your Medicare plan.
