CPT® Code 62326

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); without imaging guidance

The procedure described by CPT® Code 62326 involves the injection of diagnostic or therapeutic substances into the lumbar or sacral (caudal) regions of the spine. This procedure includes the placement of an indwelling catheter, which allows for either continuous infusion or intermittent bolus administration of various substances, such as anesthetics, antispasmodics, opioids, steroids, or other solutions. It is important to note that neurolytic substances are explicitly excluded from this procedure. The injection is performed without the use of imaging guidance, which differentiates it from similar procedures that may require such guidance. The technique typically begins with the cleansing of the skin over the targeted spinal area, 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, which are critical areas within the spinal canal. The epidural space is the outermost layer filled with cerebrospinal fluid, while the subarachnoid space is located closer to the spinal cord. The proper placement of the needle may be confirmed through the injection of contrast dye, ensuring that the catheter is accurately positioned before the therapeutic substances are administered. After the injection, the patient is monitored for any potential adverse effects, ensuring safety and efficacy of the procedure.
