CPT® Code 62162

Neuroendoscopy, intracranial; with fenestration or excision of colloid cyst, including placement of external ventricular catheter for drainage

The procedure described by CPT® Code 62162 involves a neuroendoscopic approach to address intracranial colloid cysts. This minimally invasive technique begins with a small incision in the scalp, allowing access to the skull, where a burr hole is created. This burr hole serves as the entry point for the neuroendoscope, a specialized instrument that provides visualization of the brain's internal structures. The procedure is designed to treat conditions such as colloid cysts, which can obstruct cerebrospinal fluid (CSF) flow and lead to increased intracranial pressure. During the procedure, the neuroendoscope is carefully navigated through the brain's ventricular system, allowing the surgeon to inspect the area for any adhesions or cysts that may be present. If a colloid cyst is identified, the cyst wall is opened, and its contents are evacuated using a suction catheter. The attachment points of the cyst are then coagulated to prevent bleeding, and the cyst is excised. Additionally, if necessary, an external ventricular catheter is placed for drainage, ensuring that CSF can flow freely and reducing the risk of complications associated with cyst obstruction. This procedure is critical for alleviating symptoms related to increased intracranial pressure and restoring normal CSF circulation.
