Summary & Overview
CPT 62220: Ventricular to Venous CSF Shunt Placement
CPT code 62220 represents surgical placement of a cerebrospinal fluid (CSF) shunt from the brain’s ventricles to a venous or auricular drainage site to treat hydrocephalus and related conditions. This neurosurgical procedure is nationally significant due to the prevalence of hydrocephalus across age groups and the high resource use and care coordination required for shunt-dependent patients. The code may be reported when an open or tunneled shunt is created; an endoscopic technique is noted as an option in the procedure description.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and common billing considerations tied to 62220, plus benchmarking elements and policy-relevant updates where available. The publication highlights practice patterns relevant to hospitals and neurosurgery practices, coding variants to watch for, and areas where payer policy language can affect coverage and prior authorization workflows. Data not available in the input is flagged as such for readers seeking payer-specific rates, utilization statistics, or diagnosis mappings.
Billing Code Overview
CPT code 62220 describes the creation of a cerebrospinal fluid (CSF) shunt from the cerebral ventricles to a downstream drainage site. The procedure establishes a tube or conduit that diverts excess CSF from the ventricles to the atria, jugular veins, or auricular processes to treat conditions such as hydrocephalus. An endoscopic approach may be used when clinically appropriate.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult or pediatric individual presenting with signs of increased intracranial pressure (headache, nausea, vomiting, altered mental status, gait disturbance, declining school performance in children) and imaging-confirmed ventricular enlargement consistent with hydrocephalus. The neurosurgery team evaluates the patient in the emergency department or inpatient unit; after neurological exam and head CT or MRI confirm ventricular dilation and/or obstructive lesion, the team obtains informed consent and schedules surgical cerebrospinal fluid diversion. The operative plan includes placement of a ventriculoatrial, ventriculoperitoneal, or ventriculojugular shunt with tunneling of a catheter, valve selection, and intraoperative testing. The patient is taken to the operating room or interventional suite; anesthesia is provided (general for most patients, local with sedation in select adults). The surgeon creates a burr hole, advances a ventricular catheter into the lateral ventricle under anatomical or image-guided technique, connects the catheter to a valve and distal tubing, and tunnels the distal catheter to the chosen drainage site (atrial, jugular, or auricular process). An endoscope may be used to assist ventricular catheter placement. Postoperative care includes imaging (head CT or x‑ray of shunt series) to confirm placement and monitoring for infection, hemorrhage, or shunt malfunction. Typical sites of service are the hospital operating room, inpatient surgical unit, or ambulatory surgical center for stable elective cases. Typical service type is operative neurosurgery for CSF diversion (shunt placement).
