Radius Anesthesia of Texas was founded by a board-certified anesthesiologist with the objective of providing exceptional anesthesia care and perioperative services to the patients of Texas.

For years, Radius Texas has offered services to outpatient surgical practices. Our goal has been and will always be to provide excellent care to patients. We believe that patients should have the best care before, during, and after surgery. This is why we schedule the same anesthesia provider whenever possible to ensure continuity of care.

We can provide all the various types of anesthesia. Our providers are experienced and proficient in all of them. Our equipment is biomed inspected at regular intervals. We also have certified anesthesia technologists that will make sure your facility is stocked with the appropriate levels of anesthesia supplies.

Radius Anesthesia of Texas also has an experienced billing team. We bill for services in a compliant and patient-friendly manner. We work with client facilities to reduce the burden on their staff to provide us with the necessary information to bill for our services. We can either obtain access to necessary data from the client EMR as a HIPAA-compliant business associate or receive information in paper format in a HIPAA compliant manner. Radius Texas is the anesthesia practice of choice for surgical facilities in Texas. Our dedication to quality, attention to detail, client service, and exceptional anesthesia providers make us the perioperative partner you are looking for.

“Radius Anesthesia of Texas evaluates your practice and facilitates your anesthesia needs. Their staff is wonderful. They are professional and our patients love them. I highly recommend their services.”
