CPT® Code 62161

Neuroendoscopy, intracranial; with dissection of adhesions, fenestration of septum pellucidum or intraventricular cysts (including placement, replacement, or removal of ventricular catheter)

The procedure described by CPT® Code 62161 involves a neuroendoscopic approach to address issues within the intracranial space, specifically targeting adhesions, the septum pellucidum, or intraventricular cysts. This minimally invasive technique begins with a small incision in the scalp, followed by the creation of a burr hole in the skull to provide access to the brain's ventricular system. The neuroendoscope, a specialized instrument equipped with a camera and light source, is inserted through this burr hole, allowing for direct visualization of the affected area. The procedure is designed to dissect any adhesions that may be obstructing the flow of cerebrospinal fluid (CSF) and to fenestrate cysts or the septum pellucidum to enhance CSF circulation. The septum pellucidum is a thin membrane that separates the lateral ventricles of the brain, and its manipulation can facilitate better communication of CSF throughout the ventricular system. If necessary, a ventricular catheter may be placed to manage CSF drainage, ensuring that the patient’s intracranial pressure is appropriately regulated. This procedure is critical for alleviating symptoms associated with CSF obstruction and improving overall neurological function.
