Medicare San Antonio TX: A Straight Answer on Your Options

Looking into Medicare San Antonio TX options? Most people in Bexar County land on one of two roads: Medicare Advantage (Part C) or a Medicare Supplement (Medigap) policy. Maybe your 65th birthday is coming up, maybe you just retired from a job at Port San Antonio, or maybe your current plan just isn't cutting it anymore. Either way, the choice between these two paths affects your wallet and your access to care. Annual enrollment for 2026 runs October 15 through December 7.

Below, we walk through how Medicare actually works for San Antonio residents, which plan types are sold here, and how to line up coverage with your doctors, your prescriptions and what you can afford to spend.

Your Medicare Choices Once You Live in San Antonio

Once you're enrolled in Original Medicare (Part A and Part B), San Antonio and Bexar County residents typically pick one of two directions for the rest of their coverage.

Medicare Advantage (Part C)

These plans take the place of Original Medicare and roll your benefits into one package sold by a private carrier that Medicare has approved. A typical Advantage plan bundles in:

  • Hospital and medical coverage
  • Drug coverage in most cases
  • A defined provider network
  • Copays with an annual spending cap

A number of plans throw in dental, vision or hearing benefits too, but how generous those extras are depends entirely on the carrier and the plan you pick.

Advantage plans usually draw seniors who want a smaller monthly bill, benefits bundled together, predictable copays and coordinated care inside a network. The network is the part to watch. Carriers redraw their networks every year, so it pays to confirm your doctors are still in before you commit to anything.

Medicare Supplement (Medigap)

A Medigap policy rides alongside Original Medicare and picks up costs Medicare doesn't, such as deductibles and coinsurance. These policies come with nationwide provider access, steady medical bills, no referrals to see a specialist, and no network to worry about.

Medigap doesn't come with a drug benefit built in. You'll pair it with a standalone Part D plan to cover your prescriptions.

People who travel often, want to see any doctor without checking a network first, want fewer surprise bills, or visit the doctor frequently tend to gravitate toward Medigap.

Medicare Advantage vs. Medigap: What Actually Changes

Here's the comparison San Antonio callers bring up most often.

Medicare Advantage

  • Runs through a provider network
  • Usually a lower monthly premium
  • Copays plus a yearly out-of-pocket cap
  • Plan details can shift from one year to the next

Medicare Supplement

  • Pairs with Original Medicare, no network
  • Usually a higher monthly premium
  • Very little left for you to pay out of pocket
  • Coverage terms hold steady year to year

Medigap, Medicare Advantage and Part D, compared directly

This table lines up all three so you can see the differences at a glance. Medigap and Medicare Advantage are a choose-one situation; Part D is the drug plan you add if you go the Medigap route.

Medicare Supplement

Medigap, works alongside Original Medicare

What it covers
Your share of Part A and Part B bills, including deductibles, copays and coinsurance.

No network. Any provider nationwide who accepts Medicare works.
Monthly premium

Health questions to enroll
