CPT code 62200 denotes a ventriculocisternostomy — a neurosurgical procedure that creates an opening in the floor of the third ventricle to permit cerebrospinal fluid (CSF) drainage into the cisterna magna. This procedure addresses hydrocephalus, most often noncommunicating forms, by restoring physiologic CSF pathways and avoiding or supplementing shunt dependency. Nationally, procedures coded under 62200 are clinically significant because they involve high-acuity operative care, specialized neurosurgical teams, and resource-intensive perioperative management.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service and service type, and which major payers commonly cover or adjudicate claims for this neurosurgical intervention. The publication also outlines common modifiers associated with the code and summarizes what to expect in billing practice, coding considerations, and areas where policy updates or payer-specific rules may affect claim processing. This summary is intended for coding professionals, revenue cycle staff, and clinical managers seeking a national-level briefing on CPT code 62200 and its operational implications.
