Poisoning by unsp narcotics, intentional self-harm, init

This code signifies a patient presenting with an adverse reaction or overdose due to an unspecified narcotic, where the patient deliberately ingested or administered the substance with the intent to harm themselves. The "initial encounter" indicates that this is the first time the patient is receiving active treatment for this specific poisoning event.

This code is appropriate for emergency department visits or initial hospital admissions following a suicide attempt involving an unknown or broadly categorized narcotic. It applies when the specific narcotic cannot be identified, but the intent of self-harm is clearly documented.

• Ensure documentation explicitly states "intentional self-harm" or similar language indicating suicidal intent.
• Only use this code when the specific narcotic is truly unspecified; if a specific narcotic is known, a more precise code should be used.
• The "A" for initial encounter should be used for the entire period of active treatment for the poisoning.
