A transforaminal epidural injection is a medical procedure designed to alleviate pain associated with conditions such as foraminal stenosis and large or lateral disc herniations. This procedure involves the precise delivery of an anesthetic agent and/or steroid into the epidural space, which is the area surrounding the spinal cord and nerve roots. The injection is performed under ultrasound guidance to ensure accurate placement of the needle. During the procedure, the patient is typically positioned in a prone (face down) position on the treatment table to facilitate access to the cervical or thoracic spine. The use of fluoroscopic guidance allows the physician to visualize the needle's trajectory as it is advanced through the skin and into the nerve root foramen of the affected vertebra. Once the needle is correctly positioned within the epidural space, contrast material is injected to confirm proper placement before administering the anesthetic and/or steroid. This procedure is coded with CPT® Code 0229T for each additional cervical or thoracic level injected, following the primary procedure coded with 0228T.
