Medicare Supplement

Which Medigap plan letters can Grand Prairie buy in 2027?

Grand Prairie, Texas — If you have a Medicare Supplement (Medigap) policy, or you are thinking about buying one, the months ahead are the ones that matter. Medigap does not follow the fall Annual Enrollment Period the way Medicare Advantage and Part D do. Instead, changes trickle in on a different clock: which standardized plan letters new enrollees can buy, the yearly reset of the Part B deductible that Plans G and N are built around, insurer rate filings with the Texas Department of Insurance, and any carriers moving into or out of the state.

Here is what Grand Prairie residents should keep an eye on heading into 2027.

Which plan letters you can buy in 2027

Medigap plans are standardized by the federal government. That means a Plan G from one insurer covers the same core benefits as a Plan G from another insurer — the differences are price, customer service and any small extras a company adds on.

For anyone newly eligible for Medicare, the plan letters on the shelf are A, B, D, G, G-HD (high-deductible G), K, L, M and N. Plans C and F are only available if you were eligible for Medicare before January 1, 2020. That federal rule has not changed for 2027, and it applies in Grand Prairie the same way it applies everywhere else in the country.

If you were already enrolled in Plan C or Plan F before 2020, you can keep it. You may also be able to switch between C and F carriers in some cases, but that depends on Texas rules and medical underwriting.

The Part B deductible reset — why Plans G and N care

Plans G and N are designed around one important number: the Part B deductible. You pay that deductible out of pocket at the start of each calendar year, and then your Medigap plan begins picking up its share of covered Part B costs.

That deductible resets every January 1, and the dollar amount is set by the federal Centers for Medicare & Medicaid Services (CMS). For the exact 2027 figure, check Medicare.gov once CMS posts it — usually in the fall. If you are on Plan G-HD (high-deductible G), the annual out-of-pocket amount you must meet before the policy pays is different and also resets each year.

The short version: nothing about how these plans work is changing for 2027. What changes is the dollar figure attached to the reset, and it is worth checking so you are not surprised in January.

Rate-filing season in Texas

Medigap premiums are not fixed by Medicare. Each insurer sets its own rates and files them with the Texas Department of Insurance (TDI). Rate adjustments usually take effect on a rolling basis through the year, often tied to your policy anniversary or your birthday.

Two things to know:

1. Texas has a "birthday rule" for Medigap. Within a set window around your birthday each year, you can switch to a Medigap policy of equal or lesser benefits with the same or a different insurer, without medical underwriting. If your current premium jumps, that window is a real option to shop. 2. You can look up current rate filings and consumer guides on the TDI website, or call TDI's consumer help line. The Texas Health Information, Counseling & Advocacy Program (HICAP), the state's SHIP, offers free one-on-one Medicare counseling.

If a rate change letter shows up in your mail this fall or winter, do not panic — read it, and compare before you renew.

Carriers entering or leaving the state

The list of Medigap insurers licensed in Texas shifts a little from year to year. Some carriers add plan letters, some drop them, and occasionally a company stops writing new business in the state (existing policyholders are usually allowed to keep their coverage).

The table below lists every Medigap insurer currently selling in Texas and which plan letters each one offers. Grand Prairie is in Dallas County, and residents here can generally buy from any Texas-licensed Medigap insurer, though you should always confirm your ZIP code and eligibility with the carrier or a SHIP counselor. Familiar national names on the Texas list include AARP - UnitedHealthcare Insurance Company, Aetna Health Insurance Company, BlueCross BlueShield of Texas, Humana (Emphesys Insurance Company), Mutual of Omaha (Mutual of Omaha Insurance Company) and State Farm Mutual Automobile Insurance Company, alongside Texas-specific offerings such as Texas Farm Bureau Health Plans.
