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.

For most Medicare beneficiaries in Seabrook, TX, Plan G is the most comprehensive option available if you became eligible for Medicare after January 1, 2020. Plan N is a strong alternative with lower premiums and small copays. We can compare both for your specific situation.

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

Plan G Most popular in TX
  • Part A hospital coinsurance (up to 365 extra days after Medicare)
  • Part A deductible ($1,676 per benefit period in 2026)
  • Part A hospice care coinsurance/copay
  • Part B coinsurance or copay (20% after deductible)
  • Part B excess charges (balance billing by non-participating providers)
  • Blood — first 3 pints
  • Skilled nursing facility coinsurance
  • Foreign travel emergency (80%, up to plan limits)
  • Annual Part B deductible (~$257 in 2026) — paid once per calendar year
Best for: People who want maximum coverage and predictable, near-zero out-of-pocket risk — especially those with chronic conditions or frequent specialist visits.
Plan N Lower premium option
  • Part A hospital coinsurance (up to 365 extra days after Medicare)
  • Part A deductible ($1,676 per benefit period in 2026)
  • Part A hospice care coinsurance/copay
  • Part B coinsurance after deductible (with office visit copays)
  • Blood — first 3 pints
  • Skilled nursing facility coinsurance
  • Foreign travel emergency (80%, up to plan limits)
  • Annual Part B deductible (~$257 in 2026)
  • Part B excess charges (balance billing)
  • Up to $20 copay for some office visits
  • Up to $50 ER copay — waived if you're admitted as inpatient
Best for: People in good health who visit the doctor infrequently and prefer lower monthly premiums in exchange for modest copays.

Timing is everything with Medigap

Your one-time Medigap Open Enrollment Period

Your Medigap Open Enrollment Period is a 6-month window that begins the month you are both age 65 or older AND enrolled in Medicare Part B. During this window, carriers in TX cannot deny you coverage or charge you more due to pre-existing conditions.

  • 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.
  • Age-based rates, not health-based rates. You receive the lowest available rate tier for your age group — health conditions do not affect your premium.

After your OEP closes, insurers in TX can use medical underwriting — charging more or declining coverage based on your health history. There is no annual "open season" for Medigap.

Turning 65 in Seabrook? Contact us in the 3 months before your 65th birthday so we can have your Plan G and Plan N options — and your Part D drug plan — ready the day your Part B is effective. Your Part B effective date starts the 6-month clock.
