Same Medigap Plan G in Stockton, different price tags: how to compare insurers fairly

Stockton shoppers who sit down to pick a Medicare Supplement policy often run into the same puzzle: the coverage under a given plan letter is identical from one insurer to the next, yet the premiums are not. Stockton is in San Joaquin County, where — like the rest of California — Medigap policies are sold by private insurers under standardized federal rules. That means a Plan G from one company covers the same gaps as a Plan G from another. What changes is the price, how that price is set, and how the insurer treats you when you apply.

Here is how to line them up side by side without getting lost.

Start with the letter, not the logo

Medigap plans are standardized by the federal government. If you are newly eligible for Medicare today, you can shop Plans A, B, D, G, G-HD (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.

Once you pick a letter that fits how you use care, the coverage is locked in by law. A Plan N is a Plan N. So the honest comparison is: same letter, different insurer, different price and different service — not different benefits.

The three pricing methods, and why they matter later

California insurers can price Medigap in one of three ways, and this is often the single most important thing to ask about.

• Attained-age rated. The premium is based on your current age and typically rises as you get older. It may look lower at 65 and climb over time.
• Issue-age rated. The premium is based on your age when you first bought the policy. It does not go up simply because you had another birthday, though it can still rise with inflation and other factors.
• Community-rated (also called no-age-rated). Everyone who has the policy pays roughly the same premium, regardless of age.

None of these is automatically "better." What matters is how the premium is likely to behave five or ten years from now, not just this month. When you request a quote, ask the insurer in writing which method they use for that plan letter in your ZIP code.

Rate history is the quiet tiebreaker

Two insurers can both sell Plan G in Stockton, both use attained-age pricing, and still have very different track records for raising rates. That history is public. The California Department of Insurance publishes a Medigap rate guide that shows recent rate changes by company and plan. Reading a few years of that history tells you more than any sales brochure.

You are not looking for a company that has never raised rates — everyone does. You are looking for a pattern you can live with.

Household discounts and other quiet levers

Some insurers offer a household discount when two people in the same home have a policy with them, or when a spouse or partner is enrolled. The size and rules vary by company, and not every insurer offers one at all. It is worth asking about directly, because it will not always show up on a first quote.

Other things worth asking each insurer:

• Do you offer any electronic-payment or annual-payment discount?
• Are there any additional wellness or fitness benefits attached to the policy?
• How do I submit a claim, and do you coordinate directly with Medicare?

Underwriting: timing changes everything

During your six-month Medigap Open Enrollment Period — which starts the month you are 65 or older AND enrolled in Part B — insurers must sell you any Medigap policy they offer, at their best available rate, regardless of your health.

Outside that window, and outside a limited set of "guaranteed issue" situations, California insurers can generally use medical underwriting. That means they can ask health questions and decide whether to offer you a policy, and at what price. Two insurers can look at the same application and reach different decisions. If you are shopping after your initial window, ask each company up front what their underwriting looks like for your situation before you fall in love with a quote.

California also has a "birthday rule" that gives current Medigap policyholders a yearly window around their birthday to switch to another Medigap policy with equal or lesser benefits without new underwriting. SHIP counselors can walk you through whether it applies to you.

How to find every insurer selling in your ZIP code

There is no single local list of Medigap insurers we can hand you, but there are three official sources that together cover the field. The table on this page shows the standardized plan letters currently available; the insurer roster you build for yourself will slot into those letters.

• Medicare.gov Medigap policy search. Enter your Stockton ZIP code to see every insurer offering each plan letter in your area, with contact information.
• California Department of Insurance Medigap rate guide. Shows companies licensed to sell Medigap in California and their recent rate activity.
• California SHIP (HICAP). Free, unbiased counseling from trained volunteers who do not sell insurance. They can sit with you and go through quotes.

Call at least two or three insurers on the same day, ask for the same plan letter, and write down the pricing method, the household discount rules, and any underwriting questions. That gives you an apples-to-apples comparison.
