Your lifestyle, your budget, your needs. Let us help you find the Medicare Advantage Plan that fits.

When you turn 65, access to great healthcare shouldn't just stop. At least that's what we at CHRISTUS believe, which is why we created our CHRISTUS Health Medicare Complete, Medicare Plus, and Medicare Guardian plans for individuals 65 and older. If you are 65 years of age or will soon be click below to enroll today.

With Original Medicare, only 80 percent of your health care is covered, leaving a 20 percent gap. With a Medicare Advantage plan, 100 percent of your Medicare benefits are covered with no or low monthly plan premium, low copayments, and no deductibles. The plan also offers extra coverage and utilizes a team of doctors to coordinate your health coverage to ensure you are offered the best health care at the best value.

With the open enrollment period spanning from Oct. 15, 2024 through Dec. 7, 2024, now is the time to ensure you have the coverage you need for 2023. If you're still unsure what plan is right for you or if you're eligible, contact us or call 1-469-282-0404 (711 for TTY users). Our hours of operation are 8:00 am to 8:00 pm CST, 7 days a week during the open enrollment period.  

NOTE: Outside of open enrollment, you may enroll when you turn 65 or if you qualify for a Special Enrollment Period (SEP). Learn more about SEPs.
