Medicare Supplement

Before You Buy Medigap in San Jose, Compare This

If you live in San Jose and are shopping for a Medicare Supplement policy, one of the most useful things to know up front is this: a Plan G is a Plan G, no matter which company sells it. The letter defines the coverage. What changes from one insurer to the next is the price, how that price is calculated, how it may rise over time, and whether you can qualify without medical questions.

San Jose is in Santa Clara County, and California residents can choose from any Medigap insurer licensed to sell in the state. This guide walks you through how to line those insurers up side by side, using free public tools — without us naming a price or steering you to a company.

The letter is the coverage, the insurer is the price

Medigap plans sold to people newly eligible today come in these standardized letters: A, B, D, G, high-deductible G, K, L, M and N. Plans C and F remain available only to people who became eligible for Medicare before January 1, 2020.

Because the letters are standardized by federal rule, the benefits inside, say, Plan N are identical from company to company. That is why comparing insurers is really a comparison of price, pricing method, rate history, discounts and underwriting rules — not benefits.

The three pricing methods you will see in California

When you look at two quotes for the same plan letter, ask the insurer which method it uses. There are three:

• Community-rated (no-age-rated): Everyone with that plan pays roughly the same premium, regardless of age. Premiums can still go up over time due to inflation and claims, but not simply because you had a birthday.
• Issue-age-rated: Your premium is based on the age you were when you bought the policy. It does not increase just because you get older, though it can still rise with inflation.
• Attained-age-rated: Your premium is based on your current age, so it typically increases as you age, on top of any inflation adjustments.

A policy that looks inexpensive today under attained-age pricing may not look the same at 78 as it does at 65. Neither method is automatically better — but the method shapes the long-term picture.

Rate history: the number the brochure will not show you

Two insurers can quote similar premiums today and behave very differently five years from now. That is why rate history matters. Ask each company how much its rates for your plan letter have increased over the past five to ten years in California.

The California Department of Insurance publishes a Medigap rate guide that shows premiums by insurer, plan letter and age. It is one of the clearest ways to see who has raised rates and by how much. Your local SHIP counselor (in California, called HICAP) can help you read it.

Household discounts and other savings some insurers offer

Many Medigap carriers in California offer a household discount — often around 5% to 15% — if you live with another adult, or if your spouse or partner also has a policy with the same company. Rules vary: some require both people to be enrolled, others only require that you share a household.

Other differences you may see between insurers:

• Whether they offer electronic funds transfer or annual-pay discounts.
• Whether they package extras like vision, hearing or gym benefits (these are not part of the standardized plan).
• Customer service ratings and claims-handling reputation.

None of those extras change the core Medigap coverage — the letter still defines that — but they can matter when two policies otherwise look alike.

Underwriting: why timing changes everything

In most states, including California, your one guaranteed chance to buy any Medigap policy without health questions is your Medigap Open Enrollment Period — a six-month window that begins the month you are 65 or older and enrolled in Part B. During that window, insurers cannot turn you down or charge more because of health conditions.

Outside that window, most California insurers can use medical underwriting to decide whether to accept you and at what rate — with some exceptions for guaranteed-issue situations, such as losing other coverage.

California also has a special rule known as the birthday rule: each year, for a set window around your birthday, you can switch to another Medigap policy with equal or lesser benefits from any insurer, without medical underwriting. This is a meaningful tool for keeping your options open, and HICAP can walk you through how it works in your case.
