Poisoning by heroin, intentional self-harm, init encntr

This code signifies a patient presenting with adverse effects resulting from the deliberate self-administration of heroin. The intent is to cause harm to oneself, and this code is used for the initial encounter for treatment of these effects.

Apply this code when documenting an overdose or other toxic effects from heroin where the patient explicitly states or clinical evidence strongly suggests a suicide attempt or self-inflicted injury. This is appropriate for the initial hospital visit or emergency department presentation for the acute management of the poisoning.

• Always confirm the intent of self-harm through documentation; if intent is unclear, consider accidental or undetermined intent codes.
• This "A" seventh character indicates the patient is receiving active treatment for the poisoning.
• Code any associated physical injuries or mental health conditions separately.
