Before You Buy Medigap in Dallas for 2027, Read This

DALLAS — As the calendar turns toward 2027, Medigap shoppers in Dallas will see the same familiar plan letters on the shelf, but a few moving parts underneath them are worth knowing before you buy or switch. Standardized plan designs are set by federal rules, while pricing and insurer participation are handled at the state level in Austin. Here is a plain-English look at what to watch this season.

What's actually changing for 2027

Medigap policies are standardized by the federal government, so a Plan G in Dallas covers the same things a Plan G covers in Houston or anywhere else in the country. What changes from year to year is not the benefits inside each letter — it's the numbers those benefits are built around, and the insurers who sell them.

Three things reset or move each year in Texas:

• The Part B deductible amount that Plans G and N are designed to leave you responsible for.
• Premium rates, which insurers file with the Texas Department of Insurance.
• The list of insurers offering each plan letter in a given ZIP code.

Plan-letter eligibility: who can buy what

If you became eligible for Medicare on or after January 1, 2020, you cannot buy Plan C or Plan F — that rule has not changed for 2027. Everyone else newly aging into Medicare in Dallas can choose from Plans A, B, D, G, G-HD (a high-deductible version of G), K, L, M and N.

Dallas is in Dallas County, and while Medigap availability is regulated at the state level rather than the county level, the Medicare.gov Medigap policy search does let you enter a ZIP code to see which insurers file plans in your area.

The yearly Part B deductible reset

Plans G and N are the two most popular letters for people newly eligible today, and both are structured around the Part B deductible. That deductible is set by CMS and resets every January 1. The 2027 figure will be announced by CMS before the year begins — you can check the current amount on Medicare.gov once it is published.

Here's why it matters: with Plan G, you pay the Part B deductible each year and the plan covers approved costs after that. With Plan N, you also pay the deductible plus small copays for some visits. When the deductible changes, so does the first-dollar amount you'll owe before your Medigap kicks in.

Rate-adjustment season in Texas

Medigap premiums are not standardized — only the benefits are. Insurers in Texas file proposed rates with the Texas Department of Insurance (TDI), and those filings are what drive the premium you see on a quote. Rate adjustments typically show up as insurers refresh their books each year.

To see what's happening with rates in your ZIP code:

• Use the Medicare.gov Medigap policy search to pull a list of insurers filing plans in Dallas ZIP codes.
• Check the Texas Department of Insurance Medigap rate guide, which publishes premium comparisons for the standardized plans.
• Call the Texas SHIP (Health Information, Counseling and Advocacy Program) for free, unbiased help comparing options.

Insurers entering or leaving

Insurer participation in the Medigap market can shift from year to year in Texas. New carriers occasionally file to enter, and others adjust the plan letters they offer. Because Medigap is guaranteed renewable, an insurer generally cannot drop you from an existing policy just because they stop selling new ones — but if you're shopping, the current list of active sellers in your ZIP is what counts.

The best place to see who is actively selling in Dallas right now is Medicare.gov's Medigap policy search. TDI's rate guide is the second stop.

How to shop smart this season

• Know your enrollment window. Your best pricing protection is your six-month Medigap Open Enrollment Period, which starts when you're 65 and enrolled in Part B. During that window, insurers cannot use medical underwriting.
• Compare identical letters. A Plan G is a Plan G — benefits are the same across insurers. Price and customer service are what differ.
• Check the deductible reset. Confirm the 2027 Part B deductible amount on Medicare.gov before you finalize a Plan G or N decision.
• Ask about household or other discounts. Texas insurers sometimes offer them; the TDI rate guide notes which ones do.
