How Do Austin Insurers Price the Same Medigap Letter?

In Austin, shoppers looking at Medicare Supplement Insurance — better known as Medigap — often ask the same question: if Plan G is Plan G, why do so many companies sell it? The short answer is that the coverage is identical, but the company behind it is not. How they price the policy, how often they raise rates, and how they treat your application can vary quite a bit. Here is how to compare the same plan letter across insurers in Texas without getting lost.

The same letter really is the same coverage

Medigap plans are standardized by federal law. That means Plan G from one company covers the exact same gaps in Original Medicare as Plan G from any other company. The benefits are set — deductibles, coinsurance and hospital days are covered the same way across insurers.

For people who became eligible for Medicare on or after January 1, 2020, the letters you can buy are A, B, D, G, G-HD, K, L, M and N. Plans C and F are still available, but only to people who were eligible for Medicare before that date.

So when you compare "Plan G" between two insurers in Austin, you are not comparing coverage. You are comparing the company: its price today, its rate history, its household discount, and how it handles underwriting.

Three ways insurers can price the same plan

Austin is in Travis County, and the insurers licensed to sell Medigap in Texas can use one of three pricing methods. This is the single biggest factor that shapes what your premium looks like five or ten years from now.

• Attained-age rated. The premium is based on your current age and goes up as you get older. It often starts lower but climbs over time.
• Issue-age rated. The premium is based on the age you were when you bought the policy. It does not go up simply because you had a birthday, though it can still rise with inflation.
• Community-rated. Everyone in the same area pays roughly the same premium regardless of age.

None of these is automatically "better." What matters is knowing which method an insurer uses so you can picture the cost curve, not just today's number.

Rate history matters as much as today's price

Any Medigap insurer can raise premiums to keep up with medical inflation and claims. Two insurers selling the same Plan G at similar prices today may have very different track records on rate increases.

The Texas Department of Insurance publishes a Medigap rate guide that shows premiums by company and, in some cases, historical increases. Reading this guide is one of the most useful things an Austin shopper can do. Ask any agent you talk to how often the company has raised rates over the last five years, and compare that answer against the state's guide.

Household discounts and underwriting

Many insurers in Texas offer a household discount — sometimes called a spousal or "two-person" discount — when more than one adult in the same home has a policy with them. The size and rules vary, so ask each company directly.

Underwriting is the other big variable. During your Medigap Open Enrollment Period — the six months that begin the month you turn 65 and are 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 a few limited guaranteed-issue situations, Texas insurers can ask health questions and decide whether to accept your application, delay it, or charge more. That is why the timing of your shopping matters as much as the shopping itself.

How to find every insurer selling in Austin

There is no single public list of Medigap insurers to reprint here, but there are three reliable ways to see all of them:

1. Medicare.gov Medigap policy search. Enter your Austin ZIP code and it will show every insurer offering each plan letter in your area, along with contact information. 2. Texas Department of Insurance rate guide. This state publication lists licensed Medigap carriers and their premiums by age, which is helpful for side-by-side comparison. 3. Texas SHIP (HICAP). Trained counselors offer free, unbiased help. They can walk you through your options without trying to sell you anything.

When you call an insurer or an agent, ask the same set of questions every time: which pricing method is used, what the rate increase history looks like, whether a household discount applies, and what underwriting will look like if you are past your Open Enrollment window.
