1. What is Medicare Supplement Plan F?

What Plan F Medicare Supplement is? Medicare Supplement Plan F, also known as Medigap Plan F, is a type of private insurance that helps cover costs not paid by Original Medicare (Part A and Part B). These may include deductibles, copayments, and coinsurance, reducing the amount you need to pay yourself.

Often considered the most comprehensive option, it can cover nearly all remaining healthcare expenses after Medicare pays. However, this plan is only available to individuals who became eligible for Medicare before 2020, as it is no longer offered to new enrollees.

2. What Does Medicare Supplement Plan F Cover?

If you’re wondering “What is a medicare supplement plan F?”, it is a Medigap policy designed to fill coverage gaps such as deductibles, copayments, and coinsurance for both Part A and Part B services, offering greater financial predictability for healthcare expenses.

Medicare Part A

Plan F provides extensive coverage for Medicare Part A (hospital insurance), making it especially valuable for inpatient care. It covers 100% of the Part A deductible, $1,736 in 2026, along with hospital coinsurance and up to an additional 365 days of hospital coverage after Medicare benefits are exhausted.

It also includes coverage for skilled nursing facility (SNF) coinsurance after day 20, hospice care coinsurance or copayments, and the first three pints of blood needed for a transfusion.

Medicare Part B

For Medicare Part B (outpatient services), Plan F helps eliminate many routine out-of-pocket expenses. It covers the Part B deductible, as well as 100% of coinsurance or copayments, which are typically around 20% of approved costs. 

In addition, Plan F pays for Part B excess charges, meaning if a provider bills more than the Medicare-approved amount, you won’t have to pay the difference. This makes it easier to budget for doctor visits and outpatient treatments.

Other Parts

Beyond Parts A and B, Plan F also includes additional protections that enhance overall coverage. It covers 80% of emergency medical care outside the United States, up to plan limits (typically a lifetime cap of $50,000), which can be helpful for travelers. This benefit is part of standardized Medigap plans defined by Medicare.

However, it’s important to note that Plan F does not cover services that Medicare itself excludes. For example, most prescription drugs are covered under Part D, not Medigap. As for acupuncture, Medicare does provide limited coverage, but only for chronic lower back pain under specific conditions, not for general use.

This means its coverage is comprehensive, but still aligned with Medicare’s approved services.

3. Is Medicare Supplement Plan F Still Available?

Medicare Supplement Plan F is no longer available to individuals who became eligible for Medicare on or after January 1, 2020. This change was implemented to phase out “first-dollar coverage” plans that cover all out-of-pocket costs from the start.

However, if you qualified for Medicare before this date, you may still be able to enroll in Plan F or keep your existing coverage. For those who are eligible, Plan F remains a comprehensive option that can significantly reduce healthcare expenses by covering many of Medicare’s remaining costs.

4. FAQs About Medicare Supplement Plan F

If you’re still unsure about how Plan F compares to other Medigap options, you’re not alone. Below, we’ll answer some of the most common questions our customers have about coverage, costs, and long-term value to help you make a more confident decision.

Why is Plan F more expensive?

Plan F usually comes with higher premiums because it offers one of the most comprehensive levels of coverage available. It covers nearly all remaining costs after Original Medicare pays its share, helping limit unexpected medical bills. This level of protection provides greater financial predictability, which is why many beneficiaries are willing to pay more for it.

Additionally, since Plan F has been closed to newly eligible Medicare enrollees since 2020, its member pool may gradually age, which can put upward pressure on premiums.

As a result, while Plan F offers strong coverage, it’s important to consider long-term affordability when comparing it with other Medigap options.

Can I switch to Plan G?

Yes, you can switch to Plan G, but approval may depend on medical underwriting unless you qualify for a guaranteed issue right. 

Plan G is a popular alternative because it offers similar coverage, except for the Part B deductible. Many beneficiaries choose to switch to lower premiums while still maintaining strong overall coverage.

5. Final Thoughts

Medicare supplement plan F remains one of the most comprehensive options for those who are still eligible, offering strong financial protection against unexpected medical costs. While it is no longer available to new Medicare enrollees, it can still provide excellent value for those who qualify. Understanding its benefits and limitations helps you make smarter coverage decisions over time.
