Same Plan G, Different Insurers: What Actually Changes

Grand Prairie shoppers looking at Medicare Supplement Insurance — usually called Medigap — often notice something confusing: the same plan letter is sold by many different companies. A Plan G from one insurer covers the exact same things as a Plan G from another. So why do the quotes look so different? The answer comes down to how each company sets its prices, whether it offers household discounts, and whether it can ask health questions before selling you a policy.

Medicare SupplementGrand Prairie, TX

Grand Prairie is in Dallas County (with parts in Tarrant and Ellis counties), and Medigap in Texas is regulated at the state level. That means the list of insurers, the standardized plan letters, and the consumer protections are the same across the city.

The plan letters, and why they are identical everywhere

Medigap policies sold in Texas today come in standardized letters: A, B, D, G, high-deductible G, K, L, M and N. Plans C and F are only available to people who were eligible for Medicare before January 1, 2020. Because the federal government sets what each letter covers, the benefits inside "Plan N," for example, are the same at every insurer that sells it. The insurer cannot add or subtract benefits from a lettered plan.

That is important because it means the shopping question is not "whose Plan G is better?" It is "whose Plan G costs less over time, and who is easiest to work with?"

Who sells Medigap in Texas

The full table below lists every insurer approved to sell Medigap in Texas, along with the specific letters each one offers. Some familiar names include AARP - UnitedHealthcare Insurance Company, Aetna Health Insurance Company, BlueCross BlueShield of Texas, Humana (Emphesys Insurance Company), Mutual of Omaha Insurance Company, State Farm Mutual Automobile Insurance Company, Texas Farm Bureau Health Plans and USAA Life Insurance Company. Smaller and regional carriers such as GPM Health and Life Insurance Company, Lumos Insurance, Nassau Life Insurance Company and Physicians Select Insurance Company also participate.

Not every insurer sells every letter. If you have your heart set on Plan D, Plan M or high-deductible G, the roster narrows quickly. The table below is the place to check that before you start collecting quotes.

The three pricing methods to ask about

When you request a quote, ask the agent or the insurer which pricing method the policy uses. Texas allows three:

• Community-rated (no-age-rated): Everyone pays roughly the same premium regardless of age. Premiums can still go up over time due to inflation and claims, but not because you had a birthday.
• Issue-age-rated: Your premium is based on the age you were when you bought the policy. A younger buying age generally locks in a lower starting rate. Premiums can still rise for other reasons.
• Attained-age-rated: Your premium is based on your current age and goes up as you get older. These policies often look cheapest at 65 and grow more expensive over time.

Two Plan G policies with very different pricing methods can look similar at age 66 and very different at age 80. Ask which one you are being quoted.

Rate history, household discounts and underwriting

Beyond the pricing method, three other things drive real-world cost and access:

Rate-increase history. Insurers file rate changes with the Texas Department of Insurance. A carrier's past increases are not a guarantee of future ones, but they give you a sense of how stable that block of business has been. The TDI publishes a Medicare Supplement rate guide you can request or download.

Household discounts. Many Medigap carriers in Texas offer a discount when more than one adult in the same household has a policy with them, or sometimes just when another adult lives with you. The percentage and the rules vary by insurer, so ask directly.

Medical underwriting. During your one-time, 6-month Medigap Open Enrollment Period — which starts the month you are 65 or older and enrolled in Part B — insurers must sell you any policy they offer at their best available rate, regardless of health. Outside that window, and outside of specific guaranteed-issue situations (like losing other coverage), Texas insurers can ask health questions and decline your application. Two insurers looking at the same medical history may reach different decisions.

How to compare, step by step

1. Decide which plan letter fits your budget and how you use care. 2. Go to Medicare.gov's Medigap policy search and enter your ZIP code to see every company selling that letter in Grand Prairie. 3. Note the pricing method listed for each policy. 4. Request the Texas Department of Insurance Medicare Supplement rate guide for historical rate-change context. 5. Call two or three insurers (or a licensed agent who represents several) and ask for a quote, the household discount rules, and whether underwriting applies to you right now. 6. Confirm the plan letter and effective date in writing before you cancel any existing coverage.
