Medicare Supplement

Before You Compare Plan G in Amarillo, Read This

Amarillo, Texas — If you've started looking at Medicare Supplement (Medigap) coverage, you've probably noticed something confusing: a Plan G from one company looks a lot like a Plan G from another, but the prices don't match. That's not a mistake, and it's not because one company is "better." Medigap plan letters are standardized by federal law, so the coverage inside a given letter is the same everywhere. What changes from insurer to insurer is how they set the price, how often that price goes up, and who they'll sell to.

Amarillo is in Potter County (and part of the metro reaches into Randall County), and Texans there can shop from a long list of insurers licensed to sell Medigap in the state. The table below lists every insurer and the plan letters each one offers in Texas.

The plan letter is the same — the company behind it isn't

Every Medigap plan sold in Texas uses one of the federally standardized letters: A, B, D, G, high-deductible G, K, L, M and N for people newly eligible today. (Plans C and F remain only for people who were eligible for Medicare before January 1, 2020.) A Plan N from one carrier pays the same share of your Part A and Part B costs as a Plan N from another carrier. If two Plan N policies cost different amounts, you are not getting different coverage — you're getting the same coverage from a different company.

That's why comparing "the same letter across insurers" is the fair way to shop. You're holding coverage constant and looking at everything else.

The three pricing methods, and why they matter later

Texas insurers can price Medigap policies in three ways:

• Community-rated (no-age-rated): Everyone with the same policy pays the same base premium, regardless of age. Premiums can still go up for inflation and claims trends.
• Issue-age-rated: Your premium is based on your age when you first bought the policy. It doesn't rise just because you get older, but it can still rise for other reasons.
• Attained-age-rated: Your premium is based on your current age and typically increases as you get older, on top of any general rate increases.

Two policies with identical coverage can look similar at 66 and feel very different at 78. Ask each insurer, in writing, which method they use for the plan letter you're considering.

Rate history is a fair question to ask

Because the coverage is fixed by law, the most useful question you can ask an insurer or agent is: "What have your rate increases looked like in Texas over the last five to ten years for this plan?" The Texas Department of Insurance publishes rate guides, and Medicare.gov's Medigap policy search shows which insurers sell which letters in your ZIP code. Neither source will pick a plan for you, but together they let you see who has been steady and who hasn't.

Household discounts and other price levers

Some insurers offer a household discount — sometimes called a spousal or "two-in-a-household" discount — that lowers the premium if another adult in your home also has a policy with them, or in some cases just lives with you. The size, rules and even the name of the discount vary by company, and Texas doesn't require it. It's worth asking each insurer directly whether they offer one and what qualifies.

Payment method (electronic funds transfer versus paper billing) can also change the premium at some carriers.

Underwriting: when the insurer gets to ask questions

There is one window when Medigap is truly easy to buy: your six-month Medigap Open Enrollment Period, which starts the month you're 65 or older and enrolled in Part B. During that window, any Texas insurer selling the plan letter you want must sell it to you at their standard rate, regardless of your health.

Outside that window, and outside a handful of federal guaranteed-issue situations, Texas insurers can use medical underwriting. That means they can ask about your health history, and they can decline you, delay coverage, or charge more. This is why the timing of your first Medigap purchase matters as much as the carrier you pick.

If you're already past your Open Enrollment window, ask whether the insurer has any underwriting shortcuts for switching between Medigap plans — some do, some don't.
