Choosing the right Medicare Supplement plan is a pivotal financial and healthcare decision for millions of seniors. For years, Medigap Plan F was the gold standard, offering the most comprehensive coverage. However, changes in federal law have made Plan G the new frontrunner for many. Understanding the critical differences between Medicare Plan F vs Plan G goes beyond comparing premiums; it requires a clear analysis of coverage, eligibility, and long-term value. This comparison will provide you with the detailed, unbiased information needed to navigate this important choice with confidence.

Understanding the Core Difference in Coverage

The fundamental difference between Medicare Supplement Plan F and Plan G is simple yet significant: the Medicare Part B deductible. Both plans are known as “first-dollar coverage” plans because they cover most or all out-of-pocket costs after Medicare Part A and Part B pay their share. This includes the Part A deductible and hospital coinsurance, Part B coinsurance or copayments, skilled nursing facility care coinsurance, and foreign travel emergency care.

However, Plan G requires you to pay the annual Medicare Part B deductible yourself, which is $240 in 2024. Once you have met that deductible within the calendar year, Plan G covers 100% of the remaining Medicare-approved costs for the services it covers, just like Plan F. Plan F, in contrast, covers that Part B deductible for you. This single distinction is the primary driver of cost differences and the central factor in your decision-making process. It transforms the comparison from a question of coverage to a calculation of annual and long-term financial impact.

Eligibility: The Critical Factor Shaping Your Options

Your ability to choose between Plan F and Plan G is not universal; it is governed by federal law. The Medicare Access and CHIP Reauthorization Act (MACRA) of 2015 instituted a key change: as of January 1, 2020, Medicare Supplement plans that cover the Part B deductible are no longer available to people who are newly eligible for Medicare. This means if your Medicare Part A coverage started on or after January 1, 2020, you cannot purchase Plan F (or Plan C, which also covers the deductible).

This legislation fundamentally shifted the Medigap landscape. Plan G, which does not cover the Part B deductible, became the most comprehensive plan available to this large and growing group of new beneficiaries. If you became eligible for Medicare before 2020, you may still be able to enroll in Plan F, provided an insurer in your state offers it to you. This creates two distinct consumer groups: those with a choice between the two, and those for whom Plan G is the top-tier option. For insurance agents and companies, this has meant a major pivot towards marketing and underwriting Plan G policies.

Analyzing Cost: Premiums vs. Out-of-Pocket Expenses

Comparing the cost of Plan F and Plan G is not as straightforward as looking at the monthly premium. You must conduct a side-by-side analysis of the total annual cost, which includes the premium plus any out-of-pocket expenses you are responsible for. Typically, because Plan G does not cover the Part B deductible, its monthly premiums are lower than those for Plan F. The savings on the premium can be substantial, often exceeding the cost of the deductible itself.

For example, if Plan G premiums are $25 per month less than Plan F, you would save $300 annually on premiums. Since the Part B deductible is $240, you would be $60 ahead for the year by choosing Plan G, even after paying the deductible. This gap can widen over time as insurers often price Plan F higher due to its closed risk pool (only those eligible before 2020), which may experience higher utilization as it ages. It is crucial to get personalized quotes from multiple carriers, as pricing methods (attained-age, issue-age, or community-rated) can significantly affect long-term costs.

When evaluating costs, consider these key financial components:

• Monthly Premium: The recurring cost for your Medigap policy, which varies by carrier, location, age, and sometimes tobacco use.
• Part B Deductible: The annual amount you pay for covered services before Plan G begins to pay (currently $240). This is your only major out-of-pocket cost with Plan G.
• Total Annual Cost: (Monthly Premium x 12) + Part B Deductible (for Plan G). Compare this figure directly with Plan F’s annual premium.
• Future Rate Increases: Historical trends suggest Plan G may have more stable premiums long-term due to a larger, healthier, and growing risk pool.

This analysis clearly shows that for most people, Plan G offers superior financial value. The lower premium usually offsets the one-time deductible payment, resulting in net annual savings. Furthermore, the stability of the Plan G risk pool is a critical factor for long-term financial planning in retirement.

Choosing the Right Plan for Your Situation

The decision between Plan F and Plan G hinges on your personal circumstances, eligibility, and preference for financial predictability. If you are eligible for both plans, the choice often comes down to a preference for a slightly higher monthly premium with zero deductible (Plan F) versus a lower monthly premium with one predictable annual out-of-pocket cost (Plan G). For those who value budgeting certainty and prefer to have all medical costs wrapped into a single monthly payment, Plan F might retain appeal, assuming the premium difference is minimal.

However, for the vast majority, Plan G is the objectively smarter financial choice. The premium savings are real and compound over years of coverage. Moreover, selecting Plan G future-proofs your coverage. If you ever need to switch Medigap plans later, having Plan G simplifies the process, whereas switching from Plan F might involve medical underwriting if you are outside your initial enrollment period. For individuals newly eligible for Medicare, Plan G is not just a good choice; it is the most comprehensive option available, providing nearly identical coverage to the former gold standard without the long-term cost concerns associated with a shrinking risk pool.

Ultimately, the best Medigap plan is the one that provides you with security and fits your budget. While Plan F and Plan G offer nearly identical coverage profiles, the modern insurance landscape, shaped by federal law and market dynamics, strongly favors Plan G for its combination of comprehensive coverage, lower typical costs, and long-term sustainability. Consulting with a licensed insurance agent who specializes in Medicare products can provide personalized quotes and help you navigate the final details based on the specific plans available in your zip code.
