Medicare Supplement Insurance (also known as Medigap) policies are standardized across insurance companies, yet significant differences exist between providers offering the same lettered plans. The primary distinctions lie not in the core benefits, which are identical by law, but rather in pricing, customer service, and additional features. This report examines what truly differentiates one Medicare Supplement provider from another to help beneficiaries make informed choices when selecting coverage.

Standardized Benefits vs. Variable Factors
Medicare Supplement plans have been standardized since 1992, meaning that Plan G from one company provides identical core coverage as Plan G from any other company. This standardization ensures that consumers can make apples-to-apples comparisons when shopping for coverage.
The standardized benefits chart shows that each lettered plan (A through N) has a specific set of benefits that remains consistent regardless of the insurer. For example, all Medigap policies cover 100% of Part A coinsurance and hospital costs up to an additional 365 days after Medicare benefits are used, while only certain plans cover the Part B deductible or Part B excess charges.
Despite identical core benefits within each plan letter, meaningful differences between insurers create substantial variation in value for consumers.
Premium Pricing as the Primary Differentiator
The most significant difference between identical lettered plans from different insurers is the premium cost. Insurance companies can set widely different prices for the exact same coverage, making price comparison essential.
Insurance companies use three primary methods to set their Medigap premiums:
- Attained-age pricing: Premiums start lower but increase as you age, becoming more expensive over time.
- Issue-age pricing: Premiums are based on your age when you first enroll and don’t increase due to aging (though they may increase due to inflation).
- Community-rated (no-age-rated) pricing: Everyone pays the same standard price regardless of age.
The pricing method significantly impacts long-term costs, even when initial premiums appear similar. For example, an attained-age policy might start cheaper but become more expensive than an issue-age policy after several years.
Company Reputation and Customer Experience
Company Reputation and Customer Experience
Customer experience varies significantly between Medicare Supplement providers. While complaints and customer satisfaction do not directly affect cost, poor plan performance can cause a drop in policy holders. When this happens, the smaller pool of insured individuals causes increased risk for the insurance company, resulting in higher premiums.
When evaluating providers, complaint rates can serve as a crucial indicator of how well a company handles claims and addresses customer concerns, as well as indicating the company’s future success.
Financial Stability and Company Size
Like the customer satisfaction, financial stability is not explicitly tied to a particular plan’s overall benefit. However, a company’s financial stability is an important consideration when purchasing any insurance product. Larger companies like UnitedHealthcare that serve beneficiaries across all 50 states may offer greater stability and consistency compared to smaller regional insurers.
Additional Benefits and Discount Opportunities
Premium Discounts
Insurance companies differentiate themselves by offering various discounts that can significantly reduce premium costs:
- Household discounts for married couples
- Non-smoker discounts
- Discounts for paying annually instead of monthly
- Automatic payment discounts for electronic funds transfer
- Multiple policy discounts
For example, Mutual of Omaha offers particularly competitive premium discounts, providing a 12% household discount and an additional 5% discount if the policy is submitted online.
Additional Coverage Options and Perks
Some insurers offer opportunities to enhance standard Medigap coverage with additional benefits:
- Anthem stands out by allowing beneficiaries to add dental and vision coverage options to their Medigap plans.
- AARP/UnitedHealthcare offers plans with various wellness extras, though these come at an additional cost.
- Some insurers, such as Humana, include memberships to fitness programs like SilverSneakers, which provides access to gyms and fitness classes tailored for older adults.
Medicare SELECT Options
Some insurers offer Medicare SELECT policies, which require beneficiaries to use specific provider networks but typically come with lower premiums. These network-restricted options could be advantageous for beneficiaries who primarily use in-network providers and want to reduce their premium costs.
Accessibility and Coverage Considerations
Geographic Availability
Not all Medicare Supplement providers offer plans in every state. While some companies like UnitedHealthcare offer plans in all 50 states, others like Anthem only offer Medigap plans in limited states. The coverage extends nationwide, but you can only purchase a plan in the area you are living. This can limit options for many Medicare beneficiaries.
Conversely, this can be a benefit for some people. Medigap premiums are highest in New York, Connecticut, and Maine, while Iowa has some of the lowest. If you purchase a plan in Iowa that is also offered in New York, and then move to New York, you will need to pay the New York premiums. However, if you buy a plan in Iowa that is not sold in New York, while you still need to change your address with the insurance company, you may continue to pay the Iowa premium rates, saving you money in the long run. This does vary from company to company, and depends on where the plan was bought and where you move, but it can make a big difference.
Available Plan Variety
Insurers differ in the number of plan types they offer. AARP/UnitedHealthcare provides as many as eight different plan base plans plus the high deductible variations, giving beneficiaries more options to choose coverage that meets their specific needs. In contrast, Cigna offers only Plans A, G, and N for new members.
High-Deductible Options
Some companies offer high-deductible versions of certain plans (Plans F and G), which feature lower monthly premiums in exchange for higher out-of-pocket costs before coverage begins. These options may be attractive for healthier beneficiaries looking to minimize monthly expenses.
How to Compare Medicare Supplement Plans Effectively
Importance of Comparing Same-Letter Plans
When comparing Medicare Supplement plans, it’s essential to compare the same letter plans across different companies (e.g., Plan G from Company A versus Plan G from Company B). The standardized benefits make such comparisons straightforward once you understand what each plan letter covers. Note, in Massachusetts, Minnesota, and Wisconsin, plans are standardized differently than the other 47 states; a Plan N in Wisconsin provides different coverage than the Plan N in Minnesota, both of which are different than a Plan N from any of the other 47 states.
Beyond Premium Costs
While initial premium costs may seem like the most important factor, you need to consider:
- Long-term premium stability based on the pricing method
- Company reputation and complaint history
- Available discounts that might apply to their situation
- Additional benefits that add value
- Provider network requirements (if considering a SELECT policy)
- Where you want to live long term
Takeaways
When comparing Medicare Supplement plans from different insurance companies, the core benefits of same-letter plans remain identical due to federal standardization. The true differentiators are premium costs, pricing methods, company reputation, customer service quality, available discounts, and additional benefits.
Beneficiaries should look beyond the initial premium to consider long-term value, evaluating how pricing structures might affect costs over time. They should also consider the company’s reputation for customer service, complaint rates, financial stability, and any value-added benefits or discount opportunities.
By carefully comparing these factors, you can identify which insurance company offers the best overall value for your specific needs-potentially saving thousands of dollars over the course of enrollment while ensuring reliable coverage and service.
