Common Language Description

The procedure described by CPT® Code 62311 involves the injection of diagnostic or therapeutic substances into the lumbar or sacral regions of the spine, specifically targeting the epidural or subarachnoid spaces. 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 using 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 appropriate space, either the epidural or subarachnoid. To confirm the correct placement of the needle, contrast material may be injected, which can also assist in performing an epidurography if necessary. Following the injection of the therapeutic or diagnostic 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 adverse reactions. It is important to note that this code is specifically for injections in the lumbar or sacral region, while CPT® Code 62310 is designated for similar procedures in the cervical or thoracic regions.
