About 63746: Operative spinal shunt removal
Reports operative removal of an implanted spinal cerebrospinal-fluid shunt when the device is taken out, rather than revised or newly placed.
Code 63746 represents operative removal of an implanted shunt that diverts cerebrospinal fluid from the spinal space. A neurosurgeon or other surgeon with relevant expertise typically performs the procedure in an operating room, accessing the implanted catheter and removing the shunt hardware. Removal may be indicated when the device is no longer needed or must be taken out; correcting or replacing an existing shunt points instead toward a revision service.
Report this code when the operative note identifies the spinal shunt and documents its removal, not for placement or revision alone. CMS assigns a 90-day major-surgery global period: the day-before preoperative visit and 90 days of related postoperative care are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
