Yes. The Medicare Advantage Plan is one of two alternatives for Medicare recipients who want to supplement the coverage they receive. Both are available through private insurers. Medicare Advantage Plan A Medicare Advantage Plan replaces your Medicare card with a private insurer's Medicare Advantage Plan card. That insurer manages your Part A, Part B, and (optional) Part D services and costs. Its coverage has its own premiums (an average of $19 monthly in 2022), copayments, and coinsurance costs. It will offer additional coverage and additional services at an additional cost. The costs vary widely, as do the options for coverage. Medigap Plan Medicare Supplement Insurance, known as Medigap, covers some of the deductibles, coinsurance, and copayments due for Medicare services. For example, you can choose a Medigap plan that has a low monthly premium but requires you to pick up the deductible every year. But if you're hospitalized for more than 60 days, it will pick up your share of the costs.
