The procedure described by CPT® Code 62310 involves the injection of diagnostic or therapeutic substances into the epidural or subarachnoid space of the cervical or thoracic regions of the spine. This procedure is performed to alleviate pain or to diagnose conditions affecting the spinal area. Prior to the injection, the skin over the targeted spinal region is thoroughly cleansed with an antiseptic solution to minimize the risk of infection. A local anesthetic is then administered to numb the area, ensuring patient comfort during the procedure. A spinal needle is carefully inserted through the skin and advanced into the epidural or subarachnoid space, which are critical areas surrounding the spinal cord. To confirm the accurate placement of the needle, contrast material may be injected, which can also assist in performing an epidurography, a diagnostic imaging technique. Following the injection of the therapeutic substance—such as an anesthetic, antispasmodic, opioid, steroid, or other non-neurolytic solutions—the patient is monitored for a period of 15 to 20 minutes to observe for any potential adverse effects from the injection. It is important to note that this code is specifically used for injections in the cervical or thoracic regions, while a different code, CPT® 62311, is designated for lumbar or sacral injections.
