Poisoning by unspecified antidepressants, assault, sequela

This code indicates a long-term consequence or complication arising from an intentional overdose or poisoning by an antidepressant, where the specific type of antidepressant is not documented. The poisoning was inflicted by another person with intent to harm. The sequela could be any lasting physical or psychological effect from the initial poisoning event.

Apply this code when documenting a chronic condition, disability, or late effect directly attributable to an assault by an unspecified antidepressant. This is used after the acute phase of the poisoning has passed and the patient is presenting for treatment of the residual effects. Examples include persistent neurological damage, organ dysfunction, or psychiatric disorders resulting from the poisoning.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly states the poisoning was an assault and that the antidepressant type was not specified.
• The "S" in the seventh character signifies a sequela; do not use for acute poisoning events.
