Neurosurgery
About 62190: Subarachnoid or subdural shunt creation
Reports creation of a cerebrospinal fluid shunt from a subarachnoid or subdural space to the peritoneum, pleural cavity, or another terminus.
A neurosurgeon creates a route to divert cerebrospinal fluid from a subarachnoid or subdural space to the peritoneal cavity, pleural cavity, or another documented destination. The procedure may be considered for selected CSF collections or pressure disorders when diversion from one of these spaces is indicated. The operative report should identify the fluid space of origin and the shunt terminus; a ventricular-origin shunt is a different service.
Report 62190 for creation of this shunt, rather than catheter replacement or irrigation. Documentation should establish the indication, the origin and destination of the shunt, and the work performed. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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. Medicare does not pay an assistant at surgery; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.
CMS billing rules for 62190

62190 billing questions
How does 62190 differ from 62180?
62190 diverts fluid from a subarachnoid or subdural space. 62180 is for a shunt originating in a cerebral ventricle.
What operative details support reporting 62190?
Document the indication, the subarachnoid or subdural origin, the destination, and that a new shunt was created. Those details distinguish this service from ventricular shunting and catheter replacement.
Can modifier 50 be used for bilateral shunt creation?
No. CMS identifies bilateral adjustment as inappropriate for this code.
Is an assistant surgeon payable?
CMS lists a statutory restriction on assistant-at-surgery payment for 62190. Co-surgeons are paid only with supporting documentation, while team surgery is not permitted.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
What happens when another procedure is performed in the same session?
Under the standard multiple-procedure rule, the highest-valued procedure is paid in full and the other procedure or procedures are subject to a 50% reduction.
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.
