Breakdown of ventricular intracranial shunt, sequela

This code signifies a mechanical failure of a ventricular intracranial shunt system, which is a device implanted to drain excess cerebrospinal fluid (CSF) from the brain. This breakdown can involve any component of the shunt, such as the catheter, valve, or reservoir, leading to impaired CSF drainage. The "sequela" designation indicates that this code is used for conditions that are residual effects or complications of the initial shunt breakdown, rather than the acute event itself.

Use this code when documenting a patient presenting with ongoing symptoms or complications directly attributable to a previously identified mechanical breakdown of their ventricular shunt. This includes situations where the patient is being treated for long-term effects, such as chronic hydrocephalus due to inadequate CSF drainage, or neurological deficits resulting from the shunt malfunction. It is appropriate for follow-up care related to the breakdown, after the acute phase has passed.

• Always assign an additional code to specify the exact nature of the sequela (e.g., specific neurological deficits, chronic hydrocephalus).
• Do not use this code for the initial, acute presentation of a shunt breakdown; instead, use the acute T85.01XA code.
• Ensure documentation clearly links the current condition to a past mechanical breakdown of the ventricular shunt.
