Medicare in San Antonio
Bexar County’s Advantage menu is deep and its care is split among University Health, Methodist Healthcare, Baptist Health System and Christus Santa Rosa. A plan that includes Methodist may exclude University, and Brooke Army Medical Center at Fort Sam Houston serves military retirees under TRICARE rules that Medicare plans do not change.
Because so many San Antonians carry TRICARE For Life, the “best” plan here is often an MA-only Advantage plan for dental and vision, or simply Original Medicare with TFL and nothing else. For everyone else we compare Advantage against a Medigap policy with your doctors, prescriptions and travel in front of us.
Major care in the area includes:
Plan networks differ — we check that your doctors and hospital are covered before you enroll.

How Medigap worksStandalone drug coverage chosen around your medications and pharmacy. 2026 out-of-pocket cap: $2,100.
How Part D worksAdvantage plans built for a chronic condition, for nursing-facility care, or for people with both Medicare and Texas Medicaid.
About SNPsQuestions from San Antonio
Bexar County typically offers a wide Medicare Advantage menu, every Medigap carrier in Texas, and the full Part D lineup. Availability is set by ZIP code and changes each plan year.
Usually neither. TFL pays secondary to Medicare and its pharmacy is creditable drug coverage. An MA-only Advantage plan can add dental or vision without duplicating your drug benefit. See our Joint Base San Antonio page.
Nothing. Independent agents are paid by the carriers when you enroll, so comparing plans and reviewing your coverage each year is free to you.
