Medicare Mistakes San Antonio Seniors Make
After years of sitting across the table from clients throughout Bexar County, we keep seeing the same handful of errors. Very few trace back to picking the "wrong" plan. Most come from a missed date, a bad assumption, or a decision made off a mailer.
Here's what to guard against before you enroll.
- Most of these mistakes are permanent, not temporary
- Almost all are avoidable with one annual review
- Deadlines do more damage than picking the wrong plan

The big ones
Seven Medicare mistakes that cost real money
1. Missing your Part B window
Without coverage from active employment, delaying Part B triggers a penalty that follows you for life. Run the math on our Part B penalty calculator before you decide to wait.2. Going without drug coverage
Not taking prescriptions today doesn't exempt you tomorrow. Going 63 or more days without creditable drug coverage adds a permanent surcharge to your premium.3. Assuming the network hasn't changed
Hospital and physician contracts get renegotiated every year. With the Medical Center District's dense cluster of hospitals and specialists, confirm your doctors each fall rather than trusting last year's answer.4. Shopping by the monthly premium alone
A $0 premium plan with the wrong drug tiers can end up costing thousands more across the year than a plan with a modest premium.5. Letting the Medigap window close
Your one guaranteed-issue Medigap window opens with Part B and lasts six months. After that, Texas carriers can ask health questions and turn you down.6. Enrolling straight off a television ad
National ads push one plan nationwide. They can't tell you whether that plan works with Methodist Healthcare or Baptist Health System here in San Antonio.
7. Never reviewing coverage again
The costliest mistake is set-and-forget. Plans reset every January 1, and a fifteen-minute annual check during Open Enrollment is usually enough to catch what changed.
Also worth knowing
Smaller missteps we fix often
We regularly see people add a standalone Part D plan while already enrolled in a Medicare Advantage plan that includes drug coverage, which can drop them out of the Advantage plan entirely. Others cancel a Medigap policy expecting to buy it back later, then can't pass underwriting. Joint Base San Antonio retirees sometimes forget to mention their TRICARE for Life coverage, and we later find out a Special Enrollment Period was available the whole time.
None of this is exotic. It's detail, and detail is exactly what a local independent agent is for. If you're just starting out, read the Medicare overview and work through the Medicare checklist.
