Displacement of ventricular intracranial shunt, sequela

This code signifies a long-term complication arising from the abnormal positioning or movement of a ventricular intracranial shunt. This displacement can lead to impaired cerebrospinal fluid drainage, potentially causing symptoms such as headaches, nausea, vomiting, or altered mental status. It indicates that the shunt is no longer in its intended anatomical location, affecting its function.

This code is appropriate for documenting the sequelae of a displaced ventricular shunt after the initial acute event has passed. It should be used when a patient presents with symptoms or findings directly attributable to the chronic or late effects of the shunt's malposition. This includes situations requiring revision or replacement due to the displacement.

• Always assign an additional code to specify the underlying cause of the hydrocephalus or other condition for which the shunt was originally placed.
• Do not use this code for acute complications or initial mechanical complications of the shunt; those are typically found in the T85.0- series without the 'S' seventh character.
• Ensure documentation clearly supports the "sequela" aspect, indicating a late effect rather than an acute or initial complication.
