If you are enrolled in a Medicare Advantage plan, Medicare services are covered through the plan, and Original Medicare will not pay for any healthcare services received by an enrollee in a Medicare Advantage plan.

  • Helps cover the cost of prescription drugs
  • May help lower your prescription drug costs and help protect against higher costs in the future


Medigap plans are supplemental insurance plans sold by private insurance companies to fill "gaps" in Original Medicare coverage. These plans are standardized across every carrier, meaning they must provide the same benefits. As of 2010, there are 11 available Medigap policies (A, B, C, D, F, high deductible F, G, K, L, M, and N). To qualify for enrollment in a Medigap policy, you must have Medicare Part A and Part B. Medigap policies only work in conjunction with the Original Medicare plan and will not pay for costs associated with Medicare Advantage. People in Medicare Advantage plans should not purchase Medigap policies. Below is a chart of the 11 available Medigap policies.
