CPT® Code 62225

The procedure described by CPT® Code 62225 involves the replacement or irrigation of a ventricular catheter, which is a medical device used to drain cerebrospinal fluid (CSF) from the ventricles of the brain. This procedure is typically indicated when a ventricular catheter becomes obstructed or malfunctions, potentially leading to increased intracranial pressure or other complications. The process begins with the insertion of a needle into the catheter tubing to irrigate it, which may help to clear any blockages. If initial attempts to aspirate and irrigate the catheter do not resolve the issue, the catheter must be replaced. This involves making a skin incision over the site of the malfunctioning catheter, disconnecting it from the shunt valve, and using a guidewire to facilitate the removal of the old catheter and the insertion of a new one. The new catheter is then secured and connected to the valve component, ensuring proper function and drainage of CSF. This procedure is critical for maintaining the normal flow of cerebrospinal fluid and preventing complications associated with catheter malfunction.
