What Is Medicare Supplement Insurance?
Medicare Supplement Insurance is private health insurance designed to help pay certain costs left behind by Original Medicare.
Unlike Medicare Advantage, a Medicare Supplement plan does not replace Original Medicare.
Instead, it works with Medicare Parts A and B to help reduce your share of eligible healthcare expenses.
Because benefits are standardized by the federal government, the coverage for a specific lettered plan is generally the same regardless of which insurance company offers it. The primary differences between carriers are often premium, customer service, and available discounts.
