Poisoning by antitussives, intentional self-harm, init

This code signifies an adverse event where an individual has deliberately ingested or administered an excessive amount of cough suppressants (antitussives) with the intent to harm themselves. This action results in a toxic effect on the body, requiring initial medical evaluation and treatment.

Apply this code when a patient presents to an emergency department or clinic following a suicide attempt involving an overdose of antitussive medication. It is appropriate for the initial visit where the poisoning is first diagnosed and managed, such as gastric lavage, administration of antidotes, or supportive care.

• Ensure documentation clearly states "intentional self-harm" and specifies antitussives as the substance.
• Always assign an additional code for the specific antitussive drug if known (e.g., T48.0X1- for codeine, T48.1X1- for dextromethorphan).
• Remember the "A" at the end indicates an initial encounter, meaning the patient is actively receiving treatment for the poisoning.
