Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 61601 covers

Neurosurgeons use this operation to remove a neoplastic, vascular, or infectious lesion involving the anterior cranial fossa from within the dura; dural repair is part of the service. A typical case may involve an olfactory-groove meningioma or another lesion extending into the anterior skull base. The procedure is performed in a hospital operating room and may involve another surgical specialty participating in the approach.

Choose the code based on the lesion’s anterior cranial fossa location and intradural operative work, not simply its diagnosis. The operative report should establish the site, the lesion’s relationship to the dura, the resection performed, and dural repair. This major procedure 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 is paid in full and other procedures are subject to the standard multiple procedure reduction. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation. Team surgery is permitted.
