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

What 61591 covers

This code represents a postauricular infratemporal route to the middle cranial fossa, generally used when a skull-base lesion requires access through the temporal bone from behind the ear. The operation may include petrous apicectomy and facial nerve mobilization, but the approach does not include resection of the internal auditory canal. Neurosurgeons and otolaryngologists with skull-base expertise may perform it, often in a hospital operating room and sometimes as part of a coordinated surgical team.

Select the code from the operative approach and documented work, not from the diagnosis alone. The report should identify the postauricular route and describe the bone work, facial nerve handling, and whether the internal auditory canal was resected. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 identifies bilateral surgery and is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is permitted.
