Poisoning by tricyclic antidepressants, assault, sequela

This code signifies a long-term or residual effect resulting from an intentional poisoning by tricyclic antidepressants, inflicted by another person. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience health problems directly attributable to that past event.

Apply this code when documenting chronic conditions, disabilities, or other lasting health issues that are a direct consequence of a tricyclic antidepressant poisoning that occurred as an act of assault. This is appropriate for follow-up visits or when managing ongoing complications years after the initial incident.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past assaultive tricyclic antidepressant poisoning.
• Do not use for acute poisoning events; this code is exclusively for sequelae.
