Medicare Supplement Insurance, also called Medigap, helps pay costs Original Medicare doesn’t cover—like copayments, coinsurance, and deductibles. At Noble Guardian Insurance Solutions, we explain how Medigap works and help you compare plans available in Grass Valley and Nevada County.

Medicare Supplement Questions, Answered Simply


  • What does Medigap cover?

    It helps with costs like copayments, coinsurance, and deductibles that Original Medicare doesn’t cover.

  • Is prescription drug coverage included?

    No. You’d need a separate Part D plan for prescription drugs.

  • When can I enroll in a Medigap plan?

    The best time is during your Medigap Open Enrollment Period, which starts when you’re 65 and enrolled in Part B.

  • Do Medigap plans work anywhere?

    Yes. Unlike many Medicare Advantage plans, Medigap coverage is generally accepted nationwide where Medicare is accepted.
