As a USAA member, you receive automatic access to a number of discounts and perks, such as reduced-price vacation packages, gym memberships, home security and more.
Choosing an insurance company with a low level of complaints means you're more likely to get your claim paid out in a timely and efficient manner.
USAA only sells Plans A, F, G and N. However, these four plans make up roughly 90% of all policies sold in California. Plans F, G and N are popular because all three offer high levels of coverage.
Cheapest Plan N: Cigna

Average cost of Cigna Medigap in California:
- High-deductible Plan F: $44
- Plan N: $104
- Plan A: $133
- Plan G: $143
- Plan F: $176
Cigna sells the cheapest Plan N policies in California, with an average price of just $104 a month. This is 21% cheaper than the state average of $131, and $8 a month cheaper than the same policy from AARP/UnitedHealthcare.
Medigap Plan N covers most of the same services as Plan G. However, you have to pay $20 for some doctor's visits and up to $50 for visits to the emergency room. Plan N also doesn't cover Medicare Part B excess charges. However, it's important to keep in mind that only 2% of doctors nationwide are authorized to make excess charges.
Cigna also offers a high-deductible Plan F, which can save you $60 a month in premium costs compared to Plan N. However, you have to pay a $2,700 deductible before your policy kicks in. You should consider a high-deductible Plan F policy if you would like to pay a lower monthly premium and you can afford potentially large out-of-pocket costs.
Although Cigna doesn't offer quite as many perks as USAA or AARP, all Medigap policyholders receive access to a 24/7 nurse health information hotline. You may also qualify for discounts related to various wellness-related products, services and subscriptions, such as fitness and nutritional programs.
Cigna receives 27% more complaints about Medicare Supplement plans compared to a similar-sized company.
If you value customer satisfaction, you should consider a Medigap provider like AARP/UnitedHealthcare, Mutual of Omaha or USAA. However, if you're fine with sacrificing some level of service in exchange for lower prices, you should strongly consider Cigna for a Plan N policy.

|---|---|---|
| Plan F | $199 | 59% |
| Plan G | $160 | 19% |
| Plan N | $131 | 11% |
| Plan J | N/A | 6% |
Rates are based on a 65-year-old female nonsmoker in California.
Plan C is the most expensive Medigap policy in California, with an average price of $202 a month. However, it doesn't provide the best coverage levels. That distinction belongs to Plan F. In California, a 65-year-old woman who doesn't smoke can expect to pay $199 a month for Plan F.
By contrast, a Medicare Supplement Plan G policy costs just $160 a month, making it 20% cheaper than Plan F. Since the only difference between Plan F and Plan G is that Plan F covers the $226 Medicare Part B annual deductible, Plan G is a better deal.
Plan G provides the best value among Medigap plans in California.
Plan F is only available to those who became eligible for Medicare before Jan. 1, 2020, meaning most 65-year-olds are not eligible for Plan F.
For 75-year-olds in California, a Plan G policy is $600 per year cheaper than Plan F, while for those aged 85, the gap grows to $672 per year.
Despite being more expensive, Plan F is far and away the most popular Medigap plan in California with 59% of the total market. Plan G is a distant second at 19%.
Plan N is the third most popular Medigap plan in California. It provides similar levels of coverage compared to Plan G, although you are responsible for copays of up to $20 for visits to the doctor and up to $50 for visits to the emergency room. You are also responsible for excess charges. If you're relatively healthy and don't have chronic medical conditions, you should consider Plan N since it's 18% cheaper than Plan G.
Roughly 6% of Medicare Supplement holders in California have Plan J. However, new enrollees can no longer get a Plan J policy.
How does age impact Medigap prices in California?
Most Medicare Supplement policies in California get more expensive as you age. Typically, your Medigap policy will be cheaper when you're 65, and you can expect the price to rise after each annual renewal.
Some companies only take your age into account when you buy the policy. Although you may see annual price increases to keep up with inflation, your policy won't jump in price just because you're getting older.
Less commonly, some companies in California require all policyholders to pay the same price per plan regardless of their age.
