What 61888 covers
A neurosurgeon exposes an implanted cranial neurostimulator receiver or pulse generator to revise or remove that component. The work concerns the cranial generator or receiver, rather than an intracranial electrode array. These procedures are generally performed in an operating room for patients with implanted neurostimulation systems, such as systems used for movement disorders or seizure treatment.
Report this code when the operative service addresses the existing cranial receiver or generator; use the insertion or replacement codes when that is the service performed, and the electrode revision code when the electrode array is the target. The operative note should identify the device component treated and whether it was revised or removed. Related postoperative visits during the 10-day global period are included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others at 50%. For bilateral reporting with modifier 50, payment is 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.
