Neurosurgery
About 63740: Implantation of internal spinal fluid shunt
Reports surgical placement of an internal shunt from the spinal subarachnoid space to another body cavity to divert cerebrospinal fluid.
A neurosurgeon places a catheter to divert cerebrospinal fluid from the spinal subarachnoid space to a destination such as the peritoneal or pleural cavity. The operation includes the surgical exposure needed for placement, including laminectomy when performed as part of the shunt procedure. This is generally an operating-room service performed in a hospital or other surgical facility, rather than a percutaneous external-drainage procedure.
Report 63740 for initial internal spinal shunt placement, not for a later revision or removal. The operative note should identify the spinal access site, shunt route and destination, indication for diversion, and work performed to implant the system. The code has 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 is inappropriate for this anatomy. Assistant-at-surgery payment may be made; co-surgeons require supporting documentation, and team surgery is not permitted.

63740 billing questions
How does 63740 differ from 63741?
63740 describes surgical implantation of an internal spinal shunt. 63741 is for percutaneous placement of a spinal subarachnoid external-drainage shunt.
Is the laminectomy separately reported?
The surgical exposure, including laminectomy performed as part of placing the shunt, is included in 63740.
Can modifier 50 be used?
No. The shunt procedure and anatomy do not support bilateral reporting with modifier 50.
What documentation supports initial placement?
Document the indication, spinal access site, shunt route and destination, and operative work establishing the internal diversion. Use a revision or removal code when that is the service performed instead.
What payment rules affect the surgical session?
The code has a 90-day global period. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures at 50%; assistant-at-surgery payment may be made, while co-surgery requires supporting documentation.
