Poisoning by antitussives, assault, initial encounter

This code signifies an intentional overdose or harmful exposure to antitussive medications, such as dextromethorphan or codeine-based cough suppressants, inflicted by another person. The patient is experiencing the initial effects or treatment for this poisoning event.

Apply this code when documentation clearly indicates a patient presenting with symptoms of antitussive poisoning due to an assault. This includes cases where an individual was forcibly given or tricked into taking an excessive amount of cough medicine by another party, and it's their first time seeking care for this specific incident.

• Always confirm the intent of the poisoning (assault) and the substance (antitussive).
• Ensure documentation specifies this is the initial encounter for treatment of the poisoning.
• Code any associated signs, symptoms, or manifestations of the poisoning as additional diagnoses.
