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
  • How much financial risk you're comfortable carrying — Medigap caps your exposure at $283 per year (Plan G), while Medicare Advantage caps it at $9,250 in-network
  • 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. The math: Part B premium $202.90/month ($2,434.80/year) + Plan G premium $165.85/month ($1,990.20/year) + Part B deductible $283/year = roughly $4,708/year in fixed, predictable costs. There's essentially no additional out-of-pocket beyond that. Compare that to an MA plan where a specialist visit might require a referral, a prior authorization, and a copay each time — with a worst-case exposure of $9,250 in a bad year. 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 dental, vision, and hearing 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. Here's the honest comparison: In a healthy year, MA saves approximately $1,500–$2,000 in premiums compared to Medigap Plan G. But if this person needs a hospital stay, they could face $9,250 in cost-sharing under MA. Under Plan G, their maximum out-of-pocket exposure is $283 — just the Part B deductible. 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

Scenario Input Result
High utilization, multiple specialists, traveler 4 specialists, 6 medications, travels 3+ months/year Medigap HIGH fit. Est. annual cost ~$4,708/yr (Plan G). Nationwide access, no prior auth.
Healthy, low utilization, wants extra benefits 1 doctor, 0 medications, wants dental/vision MA HIGH fit. Est. annual cost ~$2,435–$3,000/yr. $0 premium plans available with dental/vision/hearing.
Moderate health, budget-conscious, risk-averse 2–3 doctors, 2 medications, tight monthly budget Split: MA saves $1,500–$2,000/yr in premiums; Plan G caps OOP at $283/yr. Depends on risk tolerance.
Chronic condition, unpredictable utilization Diabetes, cardiology follow-ups, frequent labs Medigap HIGH fit. Predictable $4,708/yr beats potential $9,250 MOOP under MA in an active care year.

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. The 2026 national average for Plan G is $165.85 per month and $122.98 for Plan N, but your actual quote could be higher or lower. 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. The $9,250 in-network MOOP is the 2026 maximum — many plans set their MOOP lower. 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. With Plan G, your only predictable out-of-pocket cost is the $283 Part B deductible — everything else is covered.
  • Medicare Advantage is generally the better fit for healthy people who want low premiums and don't mind network restrictions. Many plans offer $0 premiums and extra benefits like dental, vision, and hearing that Original Medicare does not cover.
  • 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.
