Poisoning by tricyclic antidepress, undetermined, sequela

This code signifies a long-term health problem or complication arising from an exposure to tricyclic antidepressants where the intent (accidental, intentional self-harm, assault) of the poisoning is unknown. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing residual effects.

This code is appropriate for documenting chronic conditions or persistent symptoms directly attributable to a past tricyclic antidepressant poisoning of undetermined intent. Examples include ongoing cardiac arrhythmias, neurological deficits, or organ damage identified as a sequela. It should be used when the patient is no longer in the acute phase of the poisoning.

• Always assign an additional code(s) to specify the nature of the sequela (e.g., specific organ damage, neurological impairment).
• Ensure documentation clearly links the current condition to the past tricyclic antidepressant poisoning.
• Do not use this code for acute poisoning events; instead, use the appropriate acute poisoning code.
