Many of the pharmacies now have an online refill request, which is sent directly to our office. This allows us to process your refill more efficiently. Prescriptions are not processed after hours, so please allow 48 business hours from the time of your request to the time it is filled. Medications that require prior authorization from your insurance company may take up to one week. Lab Results We want you to be aware of all results of labs/tests done through our office, and it is our practice to communicate those results to you. It generally takes one to two weeks for us to receive the results and have the physician review them. Once the physician reviews your lab/test results he or she will notify you by mail, phone or at the time of your next follow-up appointment. After Hours Care UTMB Health offers a number of sites with extended hours and urgent care on evening and weekends, as well as four emergency rooms. If you need assistance after hours, please call the Access Center at (409) 772-2222 or toll free at (800) 917-8906. If you have a medical emergency, please dial 911 or go to the nearest emergency room.
