CPT® Code 64479

Injection(s), anesthetic agent(s) and/or steroid; transforaminal epidural, with imaging guidance (fluoroscopy or CT), cervical or thoracic, single level

A transforaminal epidural injection is a medical procedure designed to deliver anesthetic agents and/or steroids directly around a specific nerve root in the cervical or thoracic region of the spine. This procedure is particularly beneficial for patients experiencing pain or discomfort that may be radiating from nerve root irritation or inflammation. The foramina are small openings located between the vertebrae through which nerve roots exit the spinal canal. By utilizing imaging guidance, such as fluoroscopy or computed tomography (CT), the physician can accurately position the injection needle to ensure that the medication is delivered precisely where it is needed. The process begins with the cleansing and preparation of the skin over the targeted vertebra, followed by the careful advancement of the needle into the foramen. To confirm the correct placement of the needle, a small amount of radiopaque contrast material may be injected, enhancing the visibility of the needle's position on imaging. Once the needle is confirmed to be in the correct location, the anesthetic and/or steroid is injected around the nerve root, providing targeted relief from pain and inflammation. This procedure is coded as CPT® Code 64479 for a single level injection in the cervical or thoracic region, with additional levels being coded separately under CPT® Code 64480.
