Turning 65 in Texas? Your Complete Medicare Enrollment Guide

If you're approaching your 65th birthday in Texas, congratulations — and welcome to Medicare. This is one of the most important healthcare transitions you'll make, and understanding your options can save you thousands of dollars and ensure you have the coverage you need.

Your Initial Enrollment Period (IEP)

Your Medicare Initial Enrollment Period is a 7-month window that includes:

  • 3 months before your 65th birthday month
  • Your birthday month
  • 3 months after your birthday month

Example: If you turn 65 in June 2026, your IEP runs from March 1 through September 30, 2026.

Enrolling during your IEP ensures your coverage starts on time and helps you avoid late enrollment penalties that can increase your premiums for life.

Understanding the Parts of Medicare

Medicare Part A (Hospital Insurance) covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health care. Most people get Part A premium-free if they or their spouse paid Medicare taxes for 10+ years.

Medicare Part B (Medical Insurance) covers doctor visits, outpatient care, preventive services, and medical equipment. The standard Part B premium for 2026 is set by CMS each year.

Medicare Part C (Medicare Advantage) is an alternative to Original Medicare offered by private insurance companies. These plans bundle Part A, Part B, and usually Part D into one plan, often with additional benefits like dental, vision, hearing, and fitness programs.

Medicare Part D (Prescription Drug Coverage) helps cover the cost of prescription medications. Available as standalone plans or included in Medicare Advantage plans.

Medicare Advantage vs. Medicare Supplement in South Texas

This is one of the biggest decisions you'll make. Here's how they compare for Corpus Christi residents:

Medicare Advantage (Part C):

  • Combines hospital, medical, and often drug coverage in one plan
  • Usually includes dental, vision, and hearing benefits
  • Lower monthly premiums (many $0 premium plans available)
  • Network-based (HMO or PPO)
  • Popular carriers in South Texas: Humana, Aetna, UnitedHealthcare

Medicare Supplement (Medigap):

  • Fills the "gaps" in Original Medicare (deductibles, copays, coinsurance)
  • Freedom to see any doctor who accepts Medicare nationwide
  • Higher monthly premiums but more predictable costs
  • Standardized plans (A through N)
  • Guaranteed issue during your Medigap Open Enrollment Period

Common Mistakes to Avoid

  1. Missing your IEP — Late enrollment penalties can increase your Part B premium by 10% for each 12-month period you could have had coverage but didn't.
  2. Not reviewing Part D plans annually — Drug formularies and costs change every year.
  3. Assuming Medicare covers everything — Original Medicare doesn't cover dental, vision, hearing, or long-term care.
  4. Not comparing plans — There can be significant differences in costs and coverage between plans available in the Corpus Christi area.
