Medicare Plan G has become the most popular Medigap plan, particularly for those new to Medicare since 2020, because it offers robust coverage with highly predictable out-of-pocket costs. While the benefits of Plan G are standardized by law across all insurers, the monthly premiums, customer service, and financial stability of the companies offering these plans can vary significantly.
When choosing a Medicare Plan G provider for 2025, it’s essential to compare not just the price, but also the reputation and reliability of the insurance company. Here are some of the top insurance companies frequently cited for offering Medicare Plan G, along with key aspects to consider what is part g of medicare:
1. AARP from UnitedHealthcare
- Why it’s a top pick: UnitedHealthcare, through its partnership with AARP, is a major player in the Medigap market and consistently ranks highly for its Plan G offerings. They are often noted for competitive premiums and a wide availability across the U.S.
- Customer Satisfaction & Financial Strength: Investopedia rates them as “Best Overall” for 2025 due to competitive premiums and a better-than-expected complaint record for their size. They hold an A+ financial strength rating.
- Things to Note: To purchase an AARP-branded Medigap plan, you typically need to be an AARP member (which involves a modest annual fee). While their standard Plan G premiums are often competitive, their high-deductible Plan G premiums might be higher than some competitors. They may offer wellness extras and discounts on vision, dental, and hearing.
2. Anthem (Blue Cross Blue Shield Companies)
- Why it’s a top pick: As part of the extensive Blue Cross Blue Shield network, Anthem (and other BCBS affiliates, which operate regionally) is a strong contender. They are often cited for having some of the most competitive average Plan G premiums.
- Customer Satisfaction & Financial Strength: Anthem generally has complaint records as expected for its size and holds an A financial strength rating. Customer service can vary by region, as BCBS is a federation of independent companies.
- Things to Note: BCBS companies often have a strong local presence and deep provider relationships. Some BCBS companies may offer unique programs like “Blue to Blue” which allows easier switching between Medigap plans. They might offer mix-and-match dental/vision add-ons.
3. State Farm
- Why it’s a top pick: State Farm stands out particularly for its exceptional customer satisfaction and robust financial stability.
- Customer Satisfaction & Financial Strength: Investopedia names them “Best for Customer Satisfaction” due to receiving far fewer complaints than expected for their size. They also boast an A++ financial stability rating from A.M. Best, the highest possible score, indicating a superior ability to meet future claims.
- Things to Note: Their average Plan G premiums are generally competitive and among the best. While widely recognized, their Medigap offerings may not be available in all states.
4. Mutual of Omaha
- Why it’s a top pick: Mutual of Omaha is a long-standing and respected name in the insurance industry, known for solid customer service and competitive pricing, especially for their high-deductible Plan G options.

- Things to Note: Mutual of Omaha often offers attractive household discounts (e.g., up to 12% in some states), even if other household members don’t have their insurance. While their standard Plan G rates are competitive, their high-deductible Plan G premiums are often among the lowest in the market.
5. Aetna
- Why it’s a top pick: Aetna is a large, established insurer with a wide footprint. They are often highlighted for offering very competitive rates on high-deductible Plan G policies and for their stable rate increases over time.
- Customer Satisfaction & Financial Strength: Aetna generally holds an A financial strength rating. However, some reviews indicate a higher-than-average complaint rate for their standard Medigap plans, though this can vary by subsidiary.
- Things to Note: Aetna’s appeal for standard Plan G might be more regional, but their high-deductible Plan G premiums are consistently among the lowest, making them a strong choice for those who prefer that option. They may also offer household discounts.
6. Cigna
- Why it’s a top pick: Cigna is known for competitive pricing on certain plans, including Plan G, and for offering various premium discounts.
- Customer Satisfaction & Financial Strength: Cigna generally has an “A” (Excellent) rating from A.M. Best, indicating strong financial health. However, customer service reviews can be mixed, with some reports of higher complaint rates than average.
- Things to Note: Like other major carriers, Cigna offers standardized Plan G benefits. Their specific competitive edge in pricing might vary significantly by state and plan type.
How to Choose the Best Provider for YOU
Given that Plan G benefits are identical across all companies, your decision should primarily rest on these factors:
- Compare Premiums: Get personalized quotes from at least 3-5 different companies in your specific ZIP code. Premiums are the biggest variable.
- Check Rate Increase History: While not a guarantee, research how often and by how much a company has raised its Plan G premiums in your state historically.
- Evaluate Customer Service & Complaint Ratios: Look at independent ratings from organizations like the National Association of Insurance Commissioners (NAIC) to see complaint trends.
- Assess Financial Stability: Choose an insurer with strong financial ratings to ensure they can pay claims long-term.
- Look for Discounts: Inquire about household discounts, non-smoker discounts, or payment method discounts.
The “top” company for Medicare Plan G is ultimately the one that offers you the most competitive premium for the identical benefits, combined with excellent customer service and proven financial stability. Consulting with an independent Medicare insurance broker can be an invaluable resource, as they can provide quotes from multiple carriers and offer unbiased advice tailored to your unique situation.
