What 61580 covers

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.

How to choose

61581Craniofacial approach
The key distinction is the operative plane: 61580 is extradural, whereas 61581 is used for the intradural approach.
61584Skull base approach
61584 describes an orbitocranial approach. Choose 61580 for the documented craniofacial route to the anterior cranial fossa.
61586Skull-base resection
61586 concerns skull-base resection involving the nasopharynx. It is not the code for the extradural anterior craniofacial approach described by 61580.

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.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
