Choosing Between Medigap Plan F vs. Plan B

Christian Worstell by Christian Worstell    |    Published Jan 31, 2020    |    Reviewed by John Krahnert

What’s the difference between Medigap Plan F and Plan B?

Plan F is the only plan that covers all nine standardized benefit areas, while Plan B covers five of them. Whether you need all of the benefits of Plan F depends on your circumstances and your budget. 

Refer to the chart below to compare the basic benefits of each type of 2020 Medigap plan.

Understanding Medigap Benefits

There are nine benefit areas a Medigap plan (also called Medicare Supplement Insurance) may cover. All Medigap plans must provide at least partial coverage for four of them:

  • Part A hospital care coinsurance and hospital costs

  • Part A hospice care coinsurance or copayment

  • Part B coinsurance or copayment

  • First 3 pints of blood

The plans may cover — either partially or in full — some, all or none of the five additional benefits.

Plan F Coverage

Medigap Plan F offers all nine basic benefits available to Medigap insurance plans. 55% of Medicare beneficiaries that were enrolled in a Medigap plan had Plan F.1

Plan F’s popularity may be due to the fact that it is the most comprehensive type of Medigap policy.

In addition to the four basic Medigap benefits, Plan F also covers:

  • Medicare Part A deductible

  • Medicare Part B deductible

  • Medicare Part B excess charges

  • Skilled nursing care

  • Foreign travel emergency care

Plan F may be more expensive than other plans. When deciding which Medigap plan benefits you the most, it’s important to consider the monthly premiums and the type of health care services you require.

Plan F is no longer available for sale to new Medicare beneficiaries who became eligible for Medicare on or after January 1, 2020. If you were already eligible for Medicare before that date, you may still be able to buy Plan F if it is available where you live.

If you already had Medigap Plan F before Jan. 1, 2020, you can keep your plan as long as you continue to pay your plan premiums on time.

Plan B Coverage

Medigap Plan B coverage includes full coverage for the four basic Medigap benefits, plus the Medicare Part A deductible.

In 2020, the Medicare Part A deductible is $1,408 per benefit period.

If you don’t mind paying your Medicare Part B deductible ($198 in 2020) out of pocket — or don’t think you’ll need help paying for skilled nursing care, Part B excess charges or emergency medical care abroad — Medigap Plan B might be an attractive, more affordable option.

But if you enjoy the peace of mind of having “first-dollar” coverage for your health care expenses — and want coverage for every Medigap benefit area — Plan F may be the plan for you, if you’re qualified to apply for it.
