Best Medicare Supplement (Medigap) Companies of 2026

Updated April 2026 · Independent comparison · Reviewed by licensed Medicare agents

Same-letter Medigap plans are federally standardized — Plan G from one carrier covers the exact same benefits as Plan G from another. So the right "best company" depends on what you optimize for: lowest rate, most stable, best app, household discount, and so on. Here are our picks by category.

How we picked these

We compare every Medigap carrier with national or significant regional availability on five factors: (1) initial Plan G/N premium across age 65–75 enrollees in major metros, (2) 5-year rate-increase history, (3) A.M. Best financial-strength rating (A or better required), (4) state availability, (5) member experience (app, claim handling, customer ratings). Same-letter benefits are federally standardized, so we don't rank on benefits — only on what differs.

Our picks by category

  1. Best overall: AARP / UnitedHealthcare
  2. Best for low Plan G rates: Mutual of Omaha
  3. Best digital experience: Cigna Medicare Supplement (Loyal American)
  4. Best wellness bundle: Aetna (CVS Health)
  5. Best Medigap + Part D pairing: Humana
  6. Best regional reputation: Blue Cross Blue Shield (state plans)
  7. Best for high-deductible Plan G
  8. Best for household discounts
⭐ Best Overall

AARP / UnitedHealthcareUnderwritten by UnitedHealthcare Insurance Company

The largest Medigap carrier in the U.S. by enrollment, available in all 50 states. AARP-branded plans pair the carrier's broad availability and decent rate stability with member-only discounts that effectively lower premium 5-15% in many states.

Strengths

Available everywhere, mid-range premiums with member discounts, recognized brand, simple app, decent rate stability (~4-6% annual increases typical).

Watchouts

Not always the cheapest — regional carriers often beat AARP on premium. The 12-month "household discount" doesn't work in all states. Requires AARP membership ($16/year).

Why we pick it overall: if you want one safe pick that's available wherever you live and won't surprise you on rate increases, AARP is the obvious default. Just always quote them alongside 2-3 alternatives — sometimes you save real money elsewhere.

💰 Best for Low Plan G Rates

Mutual of OmahaMutual of Omaha Insurance Company / United World / Omaha Insurance Company

Frequently the lowest or near-lowest priced Plan G in many states, with a household-discount of up to 12% when both spouses enroll. Strong financial rating and a long Medigap track record going back to 1909.

Strengths

Among lowest Plan G premiums in many ZIP codes. Sizable household discount. A+ A.M. Best. Three sister companies (Mutual of Omaha, United World, Omaha Insurance) sometimes priced differently in the same state — worth quoting all three.

Watchouts

Customer service ratings vary by state. Phone-heavy enrollment process — less-modern app vs. competitors.

When to pick it: if low monthly premium is your top priority and you're enrolling with a spouse, Mutual of Omaha + the household discount is hard to beat in most states.
Sizable household discount A+ A.M. Best
📱 Best Digital Experience

Cigna Medicare Supplement SolutionsLoyal American Life / American Retirement Life — both Cigna companies

Cigna's Medigap line (sold under Loyal American Life and American Retirement Life) has competitive rates plus the most modern enrollee app and digital tools of the major carriers. Strong member portal, easy claim tracking, household discount.

Strengths

Best-in-class app and digital experience. Competitive rates in most states. Household discount available.

Watchouts

Two underwriting companies with different rates in the same state — agent has to quote both.

When to pick it: you want a Medigap carrier that has caught up to modern app/portal expectations and offers competitive rates.
Modern app A A.M. Best
💊 Best Wellness Bundle

AetnaAetna Health and Life Insurance Company / Continental Life Insurance Company

Now part of CVS Health — Aetna's Medigap plans pair with CVS pharmacy integration and a SilverScript Part D plan that reads as a single ecosystem. Good rates, growing app and digital tools.

Strengths

CVS pharmacy integration. SilverScript Part D companion. Strong financial rating. Growing digital tools.

Watchouts

Rates vary widely by state — sometimes very competitive, sometimes mid-pack. Continental Life sister company often priced differently.

When to pick it: you fill prescriptions at CVS and want a tighter pharmacy + Medigap experience, or you want SilverScript Part D paired with the same brand.

🔗 Best Medigap + Part D Pairing

HumanaHumana Insurance Company / CompBenefits Insurance Company

Humana is best known for Medicare Advantage but also offers solid Medigap plans. The big advantage is single-carrier billing and customer service if you pair Humana Medigap with Humana Part D.

Strengths

Single-carrier convenience for Medigap + Part D enrollees. Decent rates. Strong customer service infrastructure.

Watchouts

Medigap is not Humana's primary focus; benefits and rates lag MA in some states. Medigap availability varies by state.

When to pick it: you want one carrier handling both Medigap and Part D for billing/customer-service simplicity, and Humana is competitive in your state.
Same-carrier Part D option A- A.M. Best
🏥 Best Regional Reputation

Blue Cross Blue Shield (state-licensed plans)Independently licensed Blue plans by state — Anthem, Florida Blue, BCBS Texas, Highmark, etc.

The Blues are a federation of state-licensed plans, each independently operated. In many states the local BCBS plan has the strongest provider relationships, deepest in-state brand recognition, and competitive Medigap rates — especially for retirees with established BCBS relationships.

Strengths

Strong regional brand. Often best provider relationships in state. Some states have very competitive Medigap pricing.

Watchouts

Quality varies dramatically by state — the Blue plan in your state might be excellent or just OK. Always quote alongside a non-Blue alternative.

When to pick it: you've had Blue Cross your whole life, like the brand, and the local plan in your state is competitively priced. Not always the cheapest — but sometimes a tie-breaker on familiarity.
Strong regional brand
📊 Best for High-Deductible Plan G

Multiple carriers — Mutual of Omaha, AARP/UHC, WellabeHigh-Deductible Plan G ($2,870 deductible in 2026, then 100% coverage)

If you're healthy and want to gamble that you won't hit the federal deductible ($2,870 in 2026), High-Deductible Plan G drops your monthly premium dramatically — often to $40-$70/month. After the deductible, coverage is identical to standard Plan G.

Best for

Healthy enrollees with solid emergency savings, who want catastrophic Medicare protection at the lowest possible monthly premium.

Math

Standard Plan G: ~$140/mo × 12 = $1,680/yr. HD Plan G: ~$50/mo × 12 = $600/yr. Break-even: if your annual non-Part-B medical costs are under $2,870, HD Plan G saves $1,080/year. If you exceed it, you're worse off by the deductible.

When to pick it: you're healthy, you want predictable catastrophic coverage, and you can self-insure the first $2,870 in a typical year. Not for high-utilization patients.
Up to 65% premium savings
👫 Best for Household Discounts

Mutual of Omaha · Cigna · United American

If both spouses are Medicare-eligible and enrolling at the same time, household discount carriers can save 5-15% on each policy. Discounts vary by state and carrier — Mutual of Omaha frequently leads at up to 12%, Cigna and United American close behind.

Best for

Married couples both turning 65 (or one already on Medicare with spouse enrolling). Some carriers extend the discount to two unrelated adults sharing a residence.

Watchouts

Discount only applies if both spouses enroll with the same carrier. Some states don't allow household discounts at all (check your state).

When to pick it: couples enrolling together — shop carriers explicitly on household-discount adjusted rate, not on undiscounted rate. The carrier with the highest sticker can become cheapest after the discount.
Up to 12% savings per policy

The honest truth about "best Medigap company"

There is no single best Medigap company nationally. Same-letter Medigap benefits are federally standardized — Plan G is identical across every carrier. The "best" carrier for you is the one with the lowest premium in your specific ZIP code, plus a stable rate-increase history, plus a financial-strength rating you trust.

That changes by ZIP code. The cheapest carrier in Phoenix might be the most expensive in Boise. The most stable carrier in Florida might raise rates aggressively in Texas. The only way to know is to compare every carrier available in your specific ZIP code.

That's exactly what we do — for free, with no obligation, and at the same premium you'd pay enrolling direct with the carrier.

Frequently Asked Questions

Are all Medigap plans the same regardless of carrier?+
Same-letter Medigap plans are federally standardized. Plan G from any carrier covers the exact same benefits as Plan G from any other carrier — not even slightly different. The only differences are price, the carrier's history of premium increases, customer service quality, and any household or wellness discounts the carrier offers. This is why comparison shopping matters so much: you're paying for the same benefits at very different prices.
Which Medigap company has the lowest rates?+
It varies by state and ZIP code. As a general rule for 2026, Mutual of Omaha and several smaller regional carriers (Continental Life, Manhattan Life, Cigna Loyal American) are frequently the lowest in many states. AARP/UnitedHealthcare often comes in mid-range but with member discounts. Always compare every available carrier in your specific ZIP code — the cheapest carrier in one ZIP may be the most expensive in the next.
Is AARP Medicare Supplement (UnitedHealthcare) good?+
Yes. AARP-branded Medigap plans are underwritten by UnitedHealthcare and are the largest Medigap line in the U.S. by enrollment. Strengths: broad availability in all 50 states, decent rate stability, AARP member discounts, simple app. Weaknesses: not always the cheapest; some states have lower-priced carriers offering identical Plan G benefits.
How do I pick the best Medigap carrier for me?+
Three steps: (1) Decide on plan letter — Plan G if you want most comprehensive, Plan N if lower premium with small copays. (2) Compare every carrier offering that plan letter in your ZIP code on initial premium. (3) Check the carrier's track record on rate increases (we keep this data) — a low first-year rate that grows 12% a year ends up more expensive than a slightly higher rate that grows 4% a year. We do this analysis free.
What is the most stable Medigap company on rate increases?+
Stability varies by state, but Mutual of Omaha, AARP/UHC, and most state-licensed Blue Cross Blue Shield plans tend to have moderate, consistent rate increases (typically 3-7% annually). Smaller carriers occasionally undercut the market in year 1 with much sharper increases in years 2-3. Ask any agent for the carrier's published rate-increase history before enrolling.
Should I pick the cheapest Medigap company?+
Not always. Cheapest year-one premium isn't the same as cheapest 5-year cost. A carrier offering Plan G $20/mo cheaper today but raising rates 10%/year ends up more expensive than one $20/mo more today raising rates 4%/year. Look at: initial premium + projected 5-year cost based on rate-increase history + carrier financial strength rating (A.M. Best A or better is standard). Cheapest from a financially shaky carrier with bad rate-increase history is a trap.
