Neurosurgery
About 62161: Intracranial endoscopic cyst fenestration
Reports intracranial endoscopic dissection of adhesions or fenestration or resection of a cyst wall during neurosurgical treatment of a brain cyst.
A neurosurgeon uses an endoscope within the cranial cavity to separate intracranial adhesions or open a cyst by fenestrating or removing part of its wall. A typical use is endoscopic treatment of an intracranial cyst, such as an arachnoid cyst, to establish communication with a neighboring cerebrospinal fluid space. The procedure is generally performed in an operating room, often through a burr hole or another planned cranial access route.
Report 62161 when the operative work is endoscopic dissection of adhesions or cyst fenestration or wall resection; the operative report should identify the target and describe the endoscopic maneuver. Distinguish this work from excision of a colloid cyst or brain tumor, which has separate codes. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation. Team surgery is not permitted.
