What 62225 covers

A neurosurgeon uses this code for operative irrigation or replacement of a ventricular catheter in an existing cerebrospinal fluid drainage system. The procedure may be performed when the catheter needs attention during treatment of impaired cerebrospinal fluid drainage. It is typically provided in a hospital operating room as part of neurosurgical care; the operative report should identify the ventricular catheter and describe whether it was irrigated or replaced.

Report the code based on the work performed on the ventricular catheter, rather than for adjustment of a programmable valve or replacement of an entire shunt system. Medicare assigns a 90-day major-surgery global period, including 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. Assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

62230Shunt revisionComponent revision, not full-system replacement
Use 62225 for irrigation or replacement of the ventricular catheter. Use 62230 when the operative service revises or replaces the CSF shunt, including work beyond the ventricular catheter.
62252Shunt reprogrammingPer day
62252 is for reprogramming a programmable CSF shunt; 62225 involves operative irrigation or replacement of the ventricular catheter.
62258Shunt exchangeComplete system replacement
62258 describes removal and replacement of the complete CSF shunt system. 62225 is limited to the ventricular catheter service.

62225 billing questions

How does 62225 differ from 62230?

62225 describes irrigation or replacement of the ventricular catheter. Use 62230 when the operative work is revision or replacement of the cerebrospinal fluid shunt, such as work involving other shunt components.

Does 62225 describe replacement of the entire shunt system?

No. It addresses the ventricular catheter. Removal and replacement of a complete shunt system is represented by a different code, such as 62258.

Can modifier 50 be reported?

No. CMS identifies bilateral adjustment as inappropriate for this code.

What should the operative report document?

Document the existing ventricular catheter, the clinical reason for intervention, and whether the catheter was irrigated or replaced. The report should make clear that the service was directed to the ventricular catheter.

Is postoperative care included in the payment?

The 90-day major-surgery global period includes the day-before preoperative visit and 90 days of related postoperative care.
