Neurosurgery
About 62201: Endoscopic third ventriculostomy
Reports endoscopic creation of an internal cerebrospinal fluid pathway from the third ventricle, commonly to treat selected cases of obstructive hydrocephalus.
A neurosurgeon uses a ventricular endoscope to create an opening in the floor of the third ventricle, allowing cerebrospinal fluid to flow into the basal cisterns and bypass an obstruction. The procedure is used for selected patients with obstructive hydrocephalus, such as from aqueductal stenosis. It is generally performed in an operating room through a cranial access route; it creates an internal drainage pathway rather than implanting a shunt to another body cavity.
Report this code when the third-ventricle opening is created by neuroendoscopy. The operative report should support the endoscopic approach and the creation of the ventriculocisternostomy; a separately placed ventriculoperitoneal or ventriculoatrial shunt is a different service. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is statutorily restricted, and co-surgeons and team surgery are not permitted.
CMS billing rules for 62201
- Global period
- Major surgery with a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included.
- Multiple procedures
- Standard multiple procedure reduction: the highest-valued procedure is paid in full and others at 50% when performed in the same session.
- Bilateral procedures
- Bilateral adjustment does not apply; the descriptor or anatomy makes modifier 50 inappropriate.
- Assistant at surgery
- Statutory restriction: assistant at surgery is not paid.
- Co-surgeons
- Co-surgeons not permitted.
- Team surgery
- Team surgery not permitted.

62201 billing questions
How does this differ from 62200?
This code is for creating the third-ventricle opening by neuroendoscopy. Code 62200 is the related non-endoscopic ventriculocisternostomy approach.
Is this the same as placing a ventriculoperitoneal shunt?
No. This procedure creates an internal route for cerebrospinal fluid through the third-ventricle floor; a ventriculoperitoneal shunt diverts fluid to the peritoneal cavity.
Does the 90-day global period include related postoperative care?
Yes. CMS includes the day-before preoperative visit and 90 days of related postoperative care in the global period.
Can modifier 50 be used for bilateral performance?
No. CMS identifies bilateral adjustment as inappropriate for this code.
How does the multiple-procedure reduction work in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard 50% multiple-procedure reduction.
Can an assistant surgeon or co-surgeon be reported?
CMS lists a statutory restriction on assistant-at-surgery payment and does not permit co-surgeons or team surgery for this code.
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.
