CPT® Code 62327

Injection(s), including indwelling catheter placement, continuous infusion or intermittent bolus, of diagnostic or therapeutic substance(s) (eg, anesthetic, antispasmodic, opioid, steroid, other solution), not including neurolytic substances, interlaminar epidural or subarachnoid, lumbar or sacral (caudal); with imaging guidance (ie, fluoroscopy or CT)

The procedure described by CPT® Code 62327 involves the injection of diagnostic or therapeutic substances into the epidural or subarachnoid space of the lumbar or sacral region, utilizing imaging guidance such as fluoroscopy or computed tomography (CT). This procedure is performed to deliver medications directly to the spinal area, which can include anesthetics, antispasmodics, opioids, steroids, or other solutions, excluding neurolytic substances. The process begins with the cleansing of the skin over the targeted spinal region, followed by the administration of a local anesthetic to minimize discomfort during the procedure. A spinal needle is then carefully inserted into the epidural or subarachnoid space, typically using a paramedian or midline interlaminar approach, and this is often guided by imaging techniques to ensure accuracy. The epidural space is the outermost area of the spinal canal, filled with cerebrospinal fluid, while the subarachnoid space is located closer to the spinal cord. The use of contrast dye may be employed to verify the correct placement of the needle or to conduct an epidurography. Once the needle is properly positioned, a catheter is threaded through it and advanced into the target space, allowing for the secure delivery of the therapeutic substances. The infusion can be continuous or administered as intermittent boluses, and after the procedure, the patient is monitored for any potential adverse effects, ensuring safety and efficacy in the treatment provided.
