What 62164 covers
A neurosurgeon uses a neuroendoscope to reach and remove an intracranial brain tumor. The operation is generally performed in a hospital operating room; the approach may include an opening for access when needed. Code selection follows the tumor-excision service and endoscopic technique, not simply the tumor’s location or the presence of an endoscope during another procedure. Pituitary tumor excision and colloid cyst removal have distinct codes in this neuroendoscopy family.
The operative report should identify the tumor, the endoscopic approach, and the excision performed. This major surgery has 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 the others at 50%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Because this is an intracranial procedure rather than a paired-side service, modifier 50 is inappropriate.
