Welcome Providers!

At Allegian Health Plans, we understand the importance of working with the right doctor who will meet member health care needs. That’s why we partner with the medical community—to help improve the quality and cost effectiveness of health care for our Texas members.

We put our members’ well-being at the center of everything we do to ensure the best overall treatment and care. And we accomplish this through strong working relationships with our members' doctors and other health care providers.

We welcome providers’ interest in becoming part of our network. We look for providers who will deliver quality health care and who have a genuine desire to work with members to improve their overall health and wellness.  We look forward to partnering with health care providers to deliver better outcomes, increased member satisfaction and preventive care.

Once a provider contracts with Allegian Choice Health Plans, a provider service representative is assigned to the practice and serves as the primary point of contact. The representative visits the provider and office staff on a regular basis to share important information and assist with administrative or operational concerns.

Allegian Choice invites contracted providers to sign into our Provider Portal: Log In
