Neurosurgery
About 62230: Cerebrospinal fluid shunt revision
Reports surgical revision of an implanted cerebrospinal fluid shunt when a malfunctioning valve or tubing requires correction without replacing the entire system.
A neurosurgeon uses this code when surgically revising or replacing part of an existing cerebrospinal fluid diversion shunt, such as a valve or distal tubing, while leaving the overall system in place. Common reasons include mechanical failure, disconnection, obstruction, or migration that requires operative correction. These procedures are generally performed in a hospital operating room for patients with conditions such as hydrocephalus.
The operative report should identify the existing shunt, the component addressed, the reason for revision, and what was repaired or replaced. Distinguish a component-level revision from replacement of the complete shunt system; ventricular catheter replacement or irrigation has a separate code. This major surgery includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple procedure reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

62230 billing questions
How does this differ from code 62225?
Use 62230 for revision or replacement of a shunt component such as a valve or distal tubing. Code 62225 is for ventricular catheter replacement or irrigation.
When is code 62258 a better fit?
Code 62258 describes removal of the complete shunt system with replacement. Code 62230 is for a component-level revision that does not replace the entire system.
Can a shunt reprogramming service be reported as a revision?
No. Code 62252 is for reprogramming a programmable shunt valve; code 62230 involves operative revision or replacement of a shunt component.
What should the operative report document?
Identify the existing shunt, the malfunction or other reason for surgery, the component revised or replaced, and the work performed. This supports the distinction from ventricular catheter work and complete-system replacement.
Should modifier 50 be appended for bilateral work?
No. Modifier 50 is inappropriate for this service. Report the applicable shunt revision service without a bilateral adjustment.
How are additional procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple procedure reduction. The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
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.
