Cerebral Ventricle Bypass Qualifier

A newborn patient with posthemorrhagic neonatal hydrocephalus underwent insertion of a subgaleal shunt. An incision was made in the scalp and an extensive subgaleal cerebral spinal fluid pocket was developed anteriorly and posteriorly. The overlying dura was opened. A small brain needle was passed into the ventricular space and slow aspiration of fluid with blood was undertaken. A catheter was passed down the tract into the frontal horn. Some of the distal catheter was cut off and the remainder was tucked into the subgaleal pocket. What is the appropriate body part value and code assignment for insertion of a subgaleal shunt? ...
