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

What 61514 covers

A neurosurgeon uses a cranial opening, such as a craniectomy, trephination, or bone-flap craniotomy, to reach and excise an abscess in the supratentorial brain. This code is for operative treatment of an intracranial infection, rather than removal of a tumor or meningioma. The service is typically performed in a hospital operating room, with the operative report identifying the abscess and its location above the tentorium.

Report the code when the operative service matches the supratentorial abscess procedure, not merely because imaging or pathology identifies an abscess. Documentation should describe the cranial approach, target and location, and work performed to excise it. Medicare assigns a 90-day global period: the day-before preoperative visit and related postoperative care during that period are included. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation. Team surgery is not permitted.
