Digestive Health Associates of Texas: Garland - N PGB Hwy, TX - Garland (TX)

1 /5 Frank N: 2/27/25: BEWARE! Staff provided inaccurate information on more than one occasion! One staff member wanted to set me up with a procedure without any type of consultation. When that doctors schedule wouldnt align with mine, I was assigned to Dr. Gayle, who required a consult prior to the procedure. The consult with the nurse went fine, and the procedure was scheduled for December 2024. They had a Tricare authorization for office visits, but neglected to advise Tricare that a procedure would be needed. This resulted in me being charged for the procedure by BSW Dallas, as it was treated as a Point Of Service (POS) claim, versus an authorized procedure. I was not advised that I would be billed for the procedure. I received a bill for the procedure, paid it to avoid any credit issues, and contacted Tricare to question the charges, since my catastrophic cap had been met in August 2024. Tricare confirmed that a request for authorization for the procedure wasnt submitted, and the only thing authorized had been office visits. I reached out to the office manager, Christine Loya, and she was zero help. She basically passed the buck, and that I was on my own. I had no follow-up from Dr. Gayle, and have yet to receive a diagnosis or treatment plan. I would NEVER recommend this organization to anyone!

5 /5 Bert: They were able to get me on a trial for Ulcerative Colitis for two years. The trial medicine was free and I am fully healed. The study paid for office visits.

5 /5 Laura Swaney: Im Dr. Mark Miller patient.. Hes an excellent doctor and excellent person .. He is very caring, He listens and explains with great detail about procedures and whatever matters related to the visit ... never rushes the patient. I genuinely trust him.

5 /5 michael strawn: Dr. Miller is tops! He has always been a great person to work with. He is thorough and very knowledgeable. At my last visit he was kind to offer me some good advice and insight to another health problem I am experiencing. He set my mind at ease. Wish my primary was as knowledgeable about my other condition. Thanks Dr. Miller!

1 /5 Margaret Malone: These people are just rude. Or at least the administrative employee who answered my phone call was. They will not see you without first having something in writing from your primary care physician - whether your insurance company requires referrals or not (mine does not and I pay good money for that benefit). Funny how I am able to book an appointment with a dermatologist, an orthopedist, a gyn, and a hand surgeon without consulting my PCP and without being interrogated by some busybody. Avoid these people and find someone who will let you see a doctor without jumping through hoops first. Update: i saw my family doctor and he confirmed that I do not need a referral. Im overdue for a high risk colonoscopy but i would not contact these people, period.
