Neurosurgery
About 62194: Intracranial shunt catheter replacement or irrigation
Reports replacement or irrigation of a catheter used for intracranial cerebrospinal fluid drainage, such as during treatment of a malfunctioning shunt.
A neurosurgeon reports this service when an existing catheter used for intracranial cerebrospinal fluid drainage is replaced or irrigated. It may be performed in a hospital or other surgical setting for a patient with a CSF diversion system, including one placed to manage hydrocephalus. The work concerns the catheter intervention rather than establishing a new shunt. The operative record should identify the catheter treated and describe the replacement or irrigation performed.
Select the code based on the catheter service actually performed, and document the clinical reason, such as suspected obstruction, along with the operative findings and work. CMS assigns a 10-day global period, so related postoperative visits during that period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this service. An assistant at surgery is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

Are related postoperative visits separately reported?
Related postoperative visits during the 10-day global period are included in this procedure's global package.
Can modifier 50 be used?
No. Modifier 50 is inappropriate for this catheter service.
When is an assistant at surgery payable?

How does CMS handle another procedure performed in the same session?
The highest-valued procedure is paid in full; other procedures in the session are subject to the standard multiple-procedure reduction.
