Skull base surgery
About 61580: Extradural craniofacial anterior skull base approach
Reports an extradural craniofacial route to the anterior cranial fossa, typically for lesions involving the anterior skull base and adjacent sinonasal region.
This service creates combined cranial and facial access to the anterior cranial fossa. The surgeon elevates the frontal lobes, performs a craniotomy and facial bone osteotomies, and works in the extradural plane. It is used for selected anterior skull-base lesions, including tumors extending between the intracranial and sinonasal spaces. Neurosurgeons and head-and-neck or craniofacial surgeons may participate, commonly in a hospital operating room. The approach described here does not include maxillectomy or orbital exenteration.
Report 61580 when the operative record supports this extradural approach and its documented extent; distinguish it from an intradural approach such as 61581. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeon payment requires supporting documentation, while team surgery is permitted.

61580 billing questions
How is 61580 distinguished from 61581?
61580 describes an extradural anterior craniofacial approach. Use the intradural code when the documented approach includes work within the dura.
Does this code describe removal of the lesion?
The code identifies the specified craniofacial approach. The operative report should separately establish the definitive work performed and support any additional reported service.
What documentation supports 61580?
Document the anterior cranial fossa exposure, extradural plane, craniotomy, facial bone osteotomies, frontal lobe elevation, and the structures or lesion reached.
How does the multiple-procedure rule affect payment?
For procedures performed in the same session, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment is subject to a statutory restriction. Co-surgeon payment requires supporting documentation; team surgery is permitted.
