Same Medigap letter, different insurer: how to compare Plan G or N in Sacramento

If you live in Sacramento and you're shopping for a Medicare Supplement policy, here's a fact that trips up a lot of people: a Plan G is a Plan G, no matter who sells it. The coverage is standardized. What changes from one insurer to the next is the price and how that price behaves over time. This guide walks through how to line up the same plan letter across California insurers so you can compare apples to apples.

The plan letter is the coverage — the insurer sets the price

Medigap plans are standardized by federal law. That means a Plan G sold by one company covers exactly the same gaps in Original Medicare as a Plan G sold by another. Same for Plan N, Plan K, Plan L, and the rest.

For people newly eligible for Medicare today, the letters available are A, B, D, G, high-deductible G, K, L, M and N. Plans C and F are only available to people who became eligible for Medicare before January 1, 2020.

Because the benefits don't change between insurers, the comparison isn't really about coverage. It's about how each insurer prices the same letter and how that price is likely to move as you get older.

The three ways insurers set Medigap prices

When you look at two quotes for the same plan letter, the first thing to check is the pricing method. There are three, and they behave very differently over time.

Attained-age rated. The premium is based on your current age and generally goes up as you get older. It often looks lowest at first and climbs over the years.

Issue-age rated. The premium is based on your age when you first bought the policy. It doesn't rise just because you had a birthday, though it can still go up for inflation and other reasons.

Community rated. Everyone in the same area pays the same premium regardless of age. A 65-year-old and a 78-year-old with the same plan letter pay the same base rate.

None of these is automatically "better." What matters is how the numbers compare today and how they're likely to compare ten or fifteen years from now.

Rate history, household discounts and underwriting

Once you know the pricing method, three more things separate one insurer's Plan G from another's.

Rate history. Insurers can raise premiums over time. The California Department of Insurance publishes rate filings and a Medigap rate guide that show how each company's rates have moved. A carrier with a steadier history may be worth a second look even if the starting number isn't the lowest.

Household discount. Many insurers offer a discount if you live with another adult, or if a spouse or partner also holds a policy with them. The size of the discount and who qualifies varies by company.

Medical underwriting. During your Medigap Open Enrollment (the six months starting when you're 65 and enrolled in Part B), insurers must sell you any plan they offer at their best available rate, regardless of health. Outside that window, and outside certain guaranteed-issue situations, insurers in California can ask health questions and can decline you or charge more. California also has the "birthday rule," which lets you switch to an equal or lesser Medigap plan with the same or a different insurer within 60 days of your birthday each year without new underwriting.

How to find the insurers selling Medigap in Sacramento

Sacramento is in Sacramento County, and Medigap availability in California is set at the state and county level. There isn't a single public roster of every Medigap insurer to reprint here, so the most reliable path is to pull the list yourself.

Three places to look:

• Medicare.gov Medigap policy search. Enter your Sacramento ZIP code at medicare.gov to see which insurers offer which plan letters in your area.
• California Department of Insurance Medigap rate guide. The state publishes a guide comparing insurers' premiums and rate history for standardized plans.
• California SHIP (HICAP). The state's Health Insurance Counseling and Advocacy Program offers free, one-on-one help. Counselors don't sell anything.

Once you have the list, pick the plan letter you want, then compare across insurers on pricing method, most recent rate history, any household discount, and whether you're inside a guaranteed-issue window.

A simple way to line them up

Make a small grid. Down the left, list the insurers you found through Medicare.gov. Across the top, write: plan letter, pricing method, most recent rate change, household discount, underwriting rules for your situation. Fill it in from the rate guide and each insurer's brochure.

That grid — not a single number — is the honest comparison. Two insurers selling the same Plan G can look nearly identical today and drift apart considerably over ten years, depending on how they price and how their rates have moved.
