Displacement of ventricular intracranial shunt, subs

This code describes a situation where a ventricular intracranial shunt, which helps drain excess cerebrospinal fluid, has shifted from its intended position. This displacement can compromise the shunt's function and may lead to symptoms of hydrocephalus or shunt malfunction.

Apply this code when a patient presents for follow-up care, evaluation, or management of a previously diagnosed displacement of a ventricular intracranial shunt. This includes scenarios where the patient is being assessed for symptoms related to the displacement or for planning of corrective procedures.

• Requires an additional code to specify the underlying cause of the hydrocephalus.
• Distinguish from initial encounters (A) or sequela (S) for shunt displacement.
• Ensure documentation clearly states "displacement" and "subsequent encounter."
