AARP® / UnitedHealthcare

The country’s biggest Medigap issuer, available in all 50 states, backed by an A+ (Superior) AM Best rating, and consistently high customer-satisfaction scores.

Aetna (Accendo / CVS Health)

Part of CVS Health, offers aggressive pricing on standard and high-deductible Plan G, strong enrollment growth, and solid financial strength.

Anthem Blue Cross Blue Shield

Multiple state affiliates with some of the lowest average Plan G rates in recent quote studies, plus household discounts in many markets.

Bankers Fidelity

A 70-year-old niche carrier with responsive claims service and an A- (Excellent) AM Best rating—often appealing to shoppers who value smaller-company attention.

Blue Cross Blue Shield (other affiliates)

Deep provider networks and, in many states, a “Blue-to-Blue” rule that lets members switch Medigap letters without fresh underwriting.

Cigna

A (Excellent) AM Best rating, nationwide availability, multi-line household discounts, and a 4-star quality score from third-party reviewers.

Humana

Nationwide footprint with member perks such as vision, hearing, and fitness benefits. Premiums can run higher than average, so shop the rate.

ManhattanLife

Founded in 1850, independent, and flexible with health underwriting in some states. AM Best B++ (Good) and trending upward.

Mutual of Omaha

Second-largest Medigap book, up to 12 % household discount, and an industry-low NAIC complaint index—excellent for long-term rate stability.

State Farm

Top-tier customer-service ratings and highly competitive Plan G pricing in recent carrier-comparison research.


How We Chose These Carriers

  • Market share & stability – the ten listed companies represent roughly two-thirds of all Medigap enrollment.

  • Financial strength – A- or better AM Best ratings (or improving B++) signal the reserves to keep paying claims.

  • Customer experience – we analyzed NAIC complaint indexes and third-party reviews.

  • Plan G availability & pricing – every carrier above offers Plan G, today’s most comprehensive option for new Medicare beneficiaries.

Remember: Medigap benefits are federally standardized—Plan G at one company covers the same gaps as Plan G at another. Price, discounts, underwriting rules, and service reputation are what set carriers apart.
