About 61607: Posterior fossa extradural lesion resection

Reports craniotomy to remove an extradural lesion in the posterior cranial fossa below the tentorium, such as a neoplastic, vascular, or infectious lesion.

A neurosurgeon reports this service for craniotomy and removal of a neoplastic, vascular, or infectious lesion located outside the dura in the posterior cranial fossa below the tentorium. The operation is generally performed in a hospital operating room. The location and extradural compartment distinguish this service from resections for anterior fossa, infratemporal, or intradural lesions.

The operative report should establish the lesion’s posterior fossa location, its extradural position, and the craniotomy and resection performed. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and related postoperative care during the following 90 days. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate for this anatomy. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is permitted.
