About coding ventricular malfunction

The ICD-10-CM code for ventricular malfunction is T85.01 (Breakdown (mechanical) of ventricular intracranial (communicating) shunt).

Within T85.0 (mechanical complication of ventricular intracranial (communicating) shunt), T85.01 is specifically for breakdown (mechanical) of ventricular intracranial (communicating) shunt. Related codes cover displacement of ventricular intracranial (communicating) shunt (T85.02), leakage of ventricular intracranial (communicating) shunt (T85.03) and other mechanical complication of ventricular intracranial (communicating) shunt (T85.09).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
