CPT® Code 62322

Injection(s), of diagnostic or therapeutic substance(s) (eg, anesthetic, antispasmodic, opioid, steroid, other solution), not including neurolytic substances, including needle or catheter placement, interlaminar epidural or subarachnoid, lumbar or sacral (caudal); without imaging guidance

The procedure described by CPT® Code 62322 involves the injection of diagnostic or therapeutic substances into the lumbar or sacral (caudal) regions of the spine. This procedure is performed without the use of imaging guidance. The substances injected can include a variety of agents such as anesthetics, antispasmodics, opioids, steroids, or other solutions, but it specifically excludes neurolytic substances. The process begins with the cleansing of the skin over the targeted spinal area using an antiseptic solution, followed by the administration of a local anesthetic to minimize discomfort during the procedure. A thin spinal needle or catheter is then carefully inserted into the epidural or subarachnoid space through either a paramedian or midline interlaminar approach. The epidural space is the outermost area of the spinal canal, which contains cerebrospinal fluid and is situated between the dura mater and the vertebral wall. In contrast, the subarachnoid space is located closer to the spinal cord, nestled between the arachnoid and the pia mater. To ensure accurate placement of the needle, contrast dye may be injected prior to the therapeutic substance, allowing for confirmation of the needle's position and the visualization of the medication's distribution. After the injection, the patient is monitored for any potential adverse effects, ensuring safety and efficacy of the procedure.
