Medigap Fit Assessment

Key takeaway: Medigap and Medicare Advantage are built for different people — this assessment matches your health usage, budget, and lifestyle to the plan type that will likely cost you less and frustrate you less over time.

What this helps you decide

• Whether your level of healthcare usage makes Medigap's higher premium worth it versus Medicare Advantage's lower (or $0) premium
• Whether your doctors are accessible under the plan type you're leaning toward
• Medicare plan networks, drug coverage, and costs can change each year. Before you enroll, check your doctors, prescriptions, pharmacies, and current plan documents.
• Whether the extra benefits offered by Medicare Advantage (dental, vision, hearing) are worth the trade-offs in network restrictions and prior authorization requirements

Who this is for

• People approaching 65 who are trying to decide between plan types before their Medigap Open Enrollment Period begins — the window when you can buy Medigap without medical underwriting
• People currently in Medicare Advantage who are frustrated with prior authorizations, network restrictions, or surprise bills and are considering switching
• People who are healthy today but have family history or chronic conditions developing and want to think ahead
• Caregivers comparing plan types on behalf of a loved one with multiple specialists or complex medication needs

Example results

Example 1: Person who sees 4 specialists, takes 6 medications, and travels frequently. Medigap fit score: HIGH. This person's healthcare usage makes Medigap the clear financial winner, not just a comfort choice. Original Medicare (Part A + Part B) combined with Medigap Plan G gives them nationwide access to any provider who accepts Medicare — no network, no referrals, no prior authorization. Medicare plan networks, drug coverage, and costs can change each year. Before you enroll, check your doctors, prescriptions, pharmacies, and current plan documents. There's essentially no additional out-of-pocket beyond that. Medicare plan networks, drug coverage, and costs can change each year. Before you enroll, check your doctors, prescriptions, pharmacies, and current plan documents. For someone seeing four specialists regularly, the Medigap structure makes both financial and logistical sense.

Example 2: Healthy 65-year-old, one primary care doctor, no medications, wants dental and vision coverage. Medicare Advantage fit score: HIGH. This person is a strong MA candidate. Many $0-premium MA plans are available in most markets, meaning their only fixed Medicare cost is the $202.90 Part B premium they're already paying. With low healthcare utilization, their annual out-of-pocket costs would likely be $2,435–$3,000 total — including the Part B premium and the occasional copay. MA plans often include additional benefits not covered by Original Medicare benefits that Original Medicare doesn't cover at all. The trade-off is the $9,250 worst-case in-network MOOP if they had a serious health event, but at their current utilization level, the probability of hitting that ceiling is low. Dental alone could save them $500–$1,500 per year in benefits they'd otherwise pay for entirely out of pocket.

Example 3: Budget-conscious person with moderate health needs who values flexibility. This is the most common and most nuanced scenario. The assessment returns a split recommendation — neither option is obviously wrong, and the right answer depends on risk tolerance. Medicare plan networks, drug coverage, and costs can change each year. Before you enroll, check your doctors, prescriptions, pharmacies, and current plan documents. The question isn't really which plan is cheaper. It's how much financial uncertainty this person can absorb. If a $9,000 medical bill would significantly disrupt their finances, Medigap Plan G at $165.85/month is insurance against that outcome. If they have savings to cover a worst case, MA's lower premium might make sense year after year until — and unless — their health changes significantly.

Sample scenarios

What to do next

1. Check whether you're still in your Medigap Open Enrollment Period. Your OEP is a one-time, 6-month window that begins the month you are both 65 or older and enrolled in Part B. During this window, insurers cannot deny you coverage, charge you more for pre-existing conditions, or use medical underwriting. If your window is still open, you have maximum flexibility. If it has passed, you can still apply for Medigap but may face underwriting — your health history could affect your eligibility or your premium.
2. Get actual Plan G and Plan N premium quotes for your zip code. Averages are useful for comparison, but Medigap premiums vary significantly by location, age, gender, and tobacco use. Medicare plan networks, drug coverage, and costs can change each year. Before you enroll, check your doctors, prescriptions, pharmacies, and current plan documents. Request quotes from at least three carriers — the benefit is standardized (Plan G is the same everywhere), so price is the only variable between insurers.
3. Run a full drug cost comparison before choosing between plan types. If you take medications, a stand-alone Part D plan (paired with Original Medicare + Medigap) may cost more or less than your drugs would under a Medicare Advantage plan's formulary. Use Medicare's Plan Finder tool at Medicare.gov to enter your exact medications and compare true out-of-pocket drug costs across both plan types.
4. If you're leaning toward MA, check the specific plan's MOOP and network. Not all Medicare Advantage plans are equal. Medicare plan networks, drug coverage, and costs can change each year. Before you enroll, check your doctors, prescriptions, pharmacies, and current plan documents. Confirm that your doctors are in-network, that your medications are on formulary at an acceptable tier, and that the plan's prior authorization requirements won't interfere with your current care routine.

Key facts

• Medigap is generally the better fit for people who use healthcare frequently, see multiple specialists, or travel extensively. Medicare plan networks, drug coverage, and costs can change each year. Before you enroll, check your doctors, prescriptions, pharmacies, and current plan documents.
• Medicare Advantage is generally the better fit for healthy people who want low premiums and don't mind network restrictions. Medicare plan networks, drug coverage, and costs can change each year. Before you enroll, check your doctors, prescriptions, pharmacies, and current plan documents.
• Once your Medigap Open Enrollment Period ends, you may be subject to medical underwriting — insurance companies can charge more, impose waiting periods, or deny coverage based on pre-existing conditions. This window is one-time and does not repeat, which makes the decision especially important at age 65.
