How to confirm for your address
Medicare Advantage plan availability is set by county and ZIP code and changes every Annual Enrollment Period. See our statewide Medicare Advantage guide for enrollment timing, or confirm current plans directly with a licensed agent.
Original Medicare vs. Medicare Advantage
Every Medicare-eligible resident of Bexar County can choose between Original Medicare (Parts A and B, often paired with a separate Part D drug plan and a Medigap supplement) or a private Medicare Advantage plan that bundles hospital, medical, and usually drug coverage into one plan with an annual out-of-pocket maximum that Original Medicare alone doesn't have.
What to check before enrolling
Before picking a Medicare Advantage plan in Bexar County, confirm your specific doctors and preferred hospital are in-network, check whether your regular prescriptions are on the plan's formulary, and compare the plan's annual out-of-pocket maximum — these vary by thousands of dollars between plans that otherwise look similar on paper.
When you can enroll or switch
The Annual Enrollment Period runs October 15 through December 7 each year for switching Medicare Advantage or Part D plans, with changes taking effect January 1. A separate Medicare Advantage Open Enrollment Period from January 1 through March 31 allows one additional switch for people already enrolled in a Medicare Advantage plan.
Part D drug coverage considerations
If you take regular prescriptions, checking each Medicare Advantage plan's drug formulary in Bexar County matters just as much as checking provider networks. A medication can sit on a low-cost tier with one plan and a much higher tier with another, even among plans that otherwise look similar.
Medigap as an alternative approach
Some Medicare-eligible residents prefer Original Medicare paired with a Medigap supplement instead of Medicare Advantage, trading a monthly Medigap premium for more predictable costs and broader nationwide provider access with fewer network restrictions. Which approach makes more sense depends on your budget, health needs, and how much you travel.
Special Needs Plans in Texas
Some Medicare Advantage carriers serving Bexar County offer Special Needs Plans (SNPs) designed for people with specific chronic conditions, those eligible for both Medicare and Medicaid, or those living in an institutional setting. These plans coordinate care more tightly around the qualifying condition and are worth asking about if you fit one of these categories.
What a $0 premium plan actually means
A $0-premium Medicare Advantage plan in Bexar County doesn't mean free healthcare — you still owe copays, coinsurance, and potentially a deductible depending on the plan, and you continue paying your standard Medicare Part B premium regardless of which plan you choose. The $0 refers only to the plan's own added premium.
Getting help choosing a plan
Because Medicare Advantage plan details change every year, comparing options fresh each Annual Enrollment Period — rather than assuming last year's plan is still the best fit — is worth the time, and a licensed agent can walk through the comparison at no cost to you.
