The two most common Medigap plans in TX
Plan G vs. Plan N — what each covers
Both plans are federally standardized — Plan G coverage is identical across every insurer that sells it in TX. The only differences are the monthly premium and what you pay at the point of service.

In TX, Medigap premiums are calculated using attained-age rating — meaning your premium increases as you age.

Your one-time Medigap Open Enrollment Period

- Guaranteed acceptance. No insurer in TX can deny you coverage or charge more based on pre-existing health conditions during your OEP.
- All standardized plans available. You can choose any Medigap plan sold in TX — Plan G, Plan N, or others — without answering a single health question.
