What Are Medicare Supplement Plans?
Medicare Supplement (Medigap) plans are private insurance policies that help cover the costs that Original Medicare (Part A and Part B) does not pay in full, such as:
- Deductibles
- Copayments
- Coinsurance
Medigap plans work alongside Original Medicare, but they do not cover prescription drugs, vision, dental, or hearing services.
Among the available Medigap options, Plan F and Plan G offer the most comprehensive coverage. Let’s compare them.
Medicare Plan F: Overview
Medicare Plan F provides the most extensive coverage of all Medigap plans. It covers:
- Medicare Part A Deductible & Coinsurance
- Medicare Part B Deductible & Coinsurance
- Skilled Nursing Facility Coinsurance
- Foreign Travel Emergency Coverage
Plan F Cost & Availability
- Premiums: Higher than Plan G due to full coverage.
- Availability: Only available to those who qualified for Medicare before January 1, 2020.
Medicare Plan G: Overview
Medicare Plan G offers almost the same benefits as Plan F, with one key difference:
🚨 It does NOT cover the Medicare Part B deductible.
Plan G Cost & Availability
- Premiums: Typically lower than Plan F.
- Availability: Open to all Medicare beneficiaries.
Key Differences Between Plan F and Plan G
The following Medigap Plan Comparison Chart shows the coverage differences between all plans. Plan G does not cover the Part B deductible, which begs the question, is that coverage worth the cost?
High Deductible Plan F & Plan G
Both Plan F and Plan G offer a High Deductible (HD) version. These plans have lower premiums but require you to pay a higher out-of-pocket deductible before coverage begins.
High Deductible Plan F (HDF)
High Deductible Plan F offers the same benefits as regular Plan F but requires you to meet a high deductible of $2,900 before coverage kicks in.

High Deductible Plan G (HDG)
High Deductible Plan G functions like regular Plan G, except you must pay a high deductible of $2,900 before it covers expenses.
Since Plan F is no longer available to new enrollees, many are choosing HDG as a low-cost alternative.
