Poisoning by tricyclic antidepressants, self-harm, sequela

This code indicates a long-term consequence or complication arising from a past event of intentional self-poisoning with tricyclic antidepressants. It signifies that the acute poisoning episode has resolved, but the patient continues to experience residual effects directly attributable to that self-harm attempt.

Use this code when documenting a patient presenting with a chronic condition, organ damage, or persistent neurological deficits that are a direct result of a previous intentional overdose of tricyclic antidepressants. This applies to follow-up encounters where the focus is on managing these lasting sequelae, not the acute poisoning itself.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic kidney disease, cardiac arrhythmia).
• Ensure documentation clearly links the current condition to the past tricyclic antidepressant self-poisoning event.
• Do not use this code for the initial or acute phase of the poisoning; instead, use the appropriate acute poisoning code.
