Medicare Advantage vs Medigap in Pennsylvania

Kristy Hicks Jul 16, 2026

What is the difference between Medicare Advantage and Medigap?

Medicare Advantage is an alternative way to receive Medicare-covered services through a private plan approved by Medicare. Medigap is supplemental insurance that works with Original Medicare to help pay certain deductibles, copayments, or coinsurance. A person cannot use a Medigap policy to pay Medicare Advantage cost sharing, so these are different coverage paths rather than products normally used together.

How does provider access differ?

Many Medicare Advantage plans use provider networks and may require referrals or prior authorization for some care. Original Medicare with Medigap generally provides broad access to clinicians who accept Medicare, although the exact Medigap benefits depend on the standardized plan letter and policy. Anyone considering a plan should verify doctors, hospitals, specialists, and travel needs before enrolling.

How should yearly costs be compared?

Compare premiums, expected copayments, coinsurance, and the maximum out-of-pocket limit that applies to Medicare Advantage medical benefits. For Original Medicare with Medigap, review the Part B premium, Medigap premium, and expenses not covered by the selected policies. A plan with a low premium is not automatically the lowest-cost option for a specific person’s care pattern.

Where does prescription coverage fit?

Many Medicare Advantage plans include prescription coverage. Review the provider network, plan benefits, and current plan documents before enrolling. Use the official Medicare plan comparison tools to verify current information.

How to prepare for a Medicare comparison

  1. List doctors, hospitals, pharmacies, prescriptions, travel, and budget priorities.
  2. Compare suitable Medicare Advantage and Original Medicare/Medigap paths using current plan evidence.
  3. Confirm enrollment rights, effective dates, underwriting considerations, and prescription coverage before applying.
