For billing inquiries please contact 667-234-8437. We are a private practice contracted by St. Agnes Medical Group to provide your pre-surgery bariatric nutrition services. As mentioned in your new patient paperwork, this joint venture not only offers a multidisciplinary TEAM approach to coordinate your care but now there are NO UPFRONT COSTS at the time of service for our 7.5-hour sought-after pre-surgery Bariatric Nutrition Education Program for Dr. Averbach and Dr. Hamdallah. St. Agnes Hospital billing department will bill your insurance for the initial consultation and 2 pre-surgery education classes with GIBNC. Whatever the insurance company does not pay for is the patient's responsibility. As a result, any billing questions need to be directed to St. Agnes as that is who you have a balance with, not our office.
