What 61524 covers

This code is for neurosurgical removal of a cystic lesion in the infratentorial part of the brain, below the tentorium. The surgeon gains access through a craniectomy or craniotomy and removes the cyst. The service is generally performed in a hospital operating room; the operative report should identify the cyst and establish its infratentorial location.

Select this code when the lesion is a cyst and its location is infratentorial, rather than choosing a code for a tumor or abscess. Documentation should support the diagnosis, site, surgical approach, and removal 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%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation. Modifier 50 is inappropriate, and team surgery is not permitted.
