About 63744: Revision of spinal cerebrospinal fluid shunt
Surgical revision of an existing spinal cerebrospinal-fluid shunt is reported when the surgeon corrects a shunt problem rather than placing or removing it.
A neurosurgeon revises an existing spinal shunt used to divert cerebrospinal fluid from the spinal subarachnoid space. The operation addresses a problem with the shunt, such as impaired function or displacement, by surgically correcting the existing system. These procedures are generally performed in an operating room; the operative report should identify the shunt and describe the revision performed.
Report 63744 for revision work on an existing shunt, not for initial installation or removal alone. Documentation should state the clinical reason for revision and distinguish the work from placement of a new shunt or simple removal. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

63744 billing questions
When should 63744 be used instead of a spinal shunt insertion code?
Use 63744 when the surgeon revises an already existing spinal shunt. Initial installation is reported with the applicable insertion code, such as 63740 or 63741.
Is 63744 reported for removing a spinal shunt?
No. Removal alone is distinguished from revision and is reported with 63746. The operative report should make clear whether the surgeon revised the shunt or removed it.
What documentation supports 63744?
Document the existing spinal shunt, the reason for surgery, and the specific revision work performed. This helps distinguish revision from new placement or removal alone.
Should modifier 50 be appended for revision of paired shunts?
No. CMS identifies bilateral adjustment as inappropriate for this descriptor and anatomy; modifier 50 should not be used.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the major-surgery global period.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation, while team surgery is not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
