I/I react d/t ventricular intracranial shunt, sequela

This code signifies a long-term complication or late effect resulting from an infection or inflammatory response related to a ventricular intracranial (communicating) shunt. This indicates that the acute phase of the infection or inflammation has passed, but the patient continues to experience residual effects directly attributable to that prior event.

Use this code when documenting a patient presenting with a current condition or symptom that is a direct consequence of a previously resolved infection or inflammatory reaction involving a ventricular intracranial shunt. This applies to follow-up encounters where the sequela, not the active infection, is the focus of treatment.

• Assign this code as a secondary diagnosis when the sequela is not the primary reason for the encounter.
• Ensure documentation clearly links the current condition to a past shunt-related infection or inflammation.
• Do not use for active infections or inflammatory reactions; refer to codes in the T85.73- series for acute events.
