CPT® Code 75809

Shuntogram for investigation of previously placed indwelling nonvascular shunt (eg, LeVeen shunt, ventriculoperitoneal shunt, indwelling infusion pump), radiological supervision and interpretation

The CPT® Code 75809 refers to a specialized radiological procedure known as a shuntogram, which is performed to evaluate the functionality and patency of previously placed indwelling non-vascular shunts. These shunts may include devices such as the LeVeen shunt, ventriculoperitoneal (VP) shunt, or indwelling infusion pumps. The procedure utilizes radiopaque contrast medium and fluoroscopy to visualize the shunt system, allowing healthcare professionals to assess for potential issues such as dislodgement, malfunction, or obstruction. The VP shunt specifically facilitates the drainage of cerebrospinal fluid (CSF) from the brain's ventricles to the abdominal cavity, which is crucial for managing conditions that involve excess CSF. During the shuntogram, initial scout films are taken to locate the radiopaque catheter, followed by a series of steps that involve the removal of CSF, injection of contrast medium, and obtaining serial images to monitor the flow and function of the shunt. This comprehensive evaluation is essential for ensuring the proper functioning of the shunt system and for guiding further medical interventions if necessary.
