Medicare Plan F vs Plan G: Which Is Right for You?

If you’re exploring Medicare Supplement Insurance—also known as Medigap—you’ve likely come across Plans F and G. Both are popular for their comprehensive benefits, but they differ in availability and how they handle certain costs. Before making a decision, it’s important to understand who can sign up for each option, the differences in coverage, and how to compare costs. The more you know, the easier it will be to pick the right plan for your situation.

Who Can Enroll in Medicare Plan F?

Medigap Plan F has long been a top choice because it covers nearly every out-of-pocket cost under Original Medicare, including the Medicare Part B deductible. However, Plan F isn’t available to everyone. Only beneficiaries who were eligible for Medicare before January 1, 2020, can enroll in Plan F. If you qualified for Medicare prior to that date—even if you didn’t sign up right away—you may still have the option to purchase a Plan F policy.

Already have Plan F and like it? You can keep it. But if you became eligible for Medicare in 2020 or later, Plan F won’t be on your list of options.

Who Can Enroll in Medicare Plan G?

If you’re new to Medicare or became eligible after January 1, 2020, Medigap Plan G is the most comprehensive option currently available. Even if you do qualify for Plan F, you might find that Plan G gives you similar benefits at a better overall cost.

Plan G covers almost everything Plan F does, except the Medicare Part B deductible. This makes it a strong contender for anyone who wants robust coverage but isn’t able to enroll in Plan F—or prefers to save on premiums and handle the Part B deductible out of pocket.

Coverage Differences: Medicare Plan F vs Plan G

What Both Plans Cover:

• Medicare Part A Coinsurance & Hospital Costs: Both F and G cover these expenses for an additional 365 days beyond Medicare’s standard limits.

• Part A Deductible: Enjoy full coverage of this cost, avoiding hefty hospital bills.

• Part B Coinsurance or Copayment: Both plans pay your share of doctor and outpatient services, helping keep healthcare more affordable.

• Part B Excess Charges: If your provider charges more than the Medicare-approved amount, both plans have you covered.

• Skilled Nursing Facility Care Coinsurance: Extend your financial protection during rehabilitation or extended care.

• Blood (First Three Pints): Both F and G cover these initial, often-overlooked expenses.

• Foreign Travel Emergency Care: Receive medically necessary emergency care abroad (with certain limits).

What Only Plan F Covers:

• Medicare Part B Deductible: Plan F pays this for you, which can save you upfront costs. Plan G, on the other hand, requires you to pay the Part B deductible out of pocket.

This single benefit difference might seem minor, but it can influence cost and value when you compare monthly premiums.

Cost Considerations: Is Plan F Worth It?

Since Plan F is more comprehensive, it typically comes with higher monthly premiums. The crucial question: Is the convenience of having your Part B deductible covered worth paying extra each month?

For 2025, the Medicare Part B deductible is $257. Spread out over a year, that’s about $21.42 per month. If Plan F costs more than $21.42 per month than Plan G, you might actually save money by choosing Plan G and covering the Part B deductible yourself. Conversely, if Plan F’s premium is close to Plan G’s—less than a $21 difference each month—Plan F might be the better deal, as it simplifies your coverage and eliminates the deductible hassle.

When to Consider Switching from Plan F to Plan G

If you currently have Plan F, it’s worth reviewing your policy every year. Over time, premiums may rise, changing the cost-benefit equation. If you find that you’re paying significantly more than Plan G would cost—especially above that monthly $21 threshold—switching to Plan G could put money back in your pocket. Keep in mind that switching plans might require medical underwriting, so it’s best to explore your options during open enrollment periods or when you have guaranteed issue rights.

High-Deductible Options

In some states, both Plan F and Plan G offer high-deductible versions. These plans come with lower monthly premiums but require meeting a higher deductible before coverage kicks in. If you’re in good health and prefer lower monthly costs, a high-deductible plan might be appealing. Just be sure you’re comfortable paying more out of pocket before receiving benefits.

How to Compare Medigap Plans

1. Check Availability:

Not all insurance companies offer every Medigap plan, and availability can vary by state. Focus first on what’s offered in your area.

2. Compare Premiums:

For identical coverage, premiums can vary widely by insurer. Don’t settle for the first quote you see—shop around and request multiple estimates.

3. Consider Future Costs:

Plans often increase in price as you get older. While Plan F and Plan G benefits are standardized, pricing methods differ. Check the company’s track record for rate increases to avoid surprises down the road.

4. Look for Extras:

While Medigap benefits are standardized, some insurers offer perks such as discounts, gym memberships, or wellness programs. These can add value to your plan without affecting the core coverage.

Choosing the Right Plan for Your Needs

When comparing Medicare Plan F vs Plan G, start by determining your eligibility. If you’re not grandfathered into Plan F (meaning you became eligible for Medicare in 2020 or later), then Plan G is your top-tier choice. If you do have the option for Plan F, crunch the numbers: compare how much extra you’d pay in premiums against the convenience of skipping the Part B deductible.

Remember, both options are designed to shield you from most out-of-pocket costs that Original Medicare doesn’t cover. Either way, you’re choosing a plan that can provide valuable peace of mind.

Final Thoughts

Deciding between Medicare Plan F vs Plan G boils down to eligibility, cost, and personal preference. Evaluate how much you’re willing to pay for the simplicity of having the Part B deductible covered. If Plan F’s premiums outpace the potential savings, Plan G might be the smarter choice.

Before making a final decision, consider speaking with a trusted insurance agent or a Medicare counselor. They can help you compare current plan rates, review your health history, and identify any special enrollment opportunities. With the right guidance and a clear understanding of your options, you’ll be well on your way to selecting the Medigap coverage that aligns best with your needs and budget.
