Poisoning by chloramphenicol group, self-harm, init

This code signifies a patient presenting with adverse effects resulting from the deliberate ingestion or administration of a chloramphenicol-based medication with the intent to harm oneself. The patient is in the initial phase of treatment for this poisoning.

Apply this code when documentation clearly indicates a self-inflicted overdose or misuse of chloramphenicol. This is appropriate for the initial hospital visit or emergency department encounter where the poisoning is first evaluated and treated.

• Always verify the intent (intentional self-harm) and the specific substance (chloramphenicol group).
• Ensure the encounter is the "initial" one for this specific poisoning event. Subsequent encounters would use a different seventh character.
• Code all manifestations of the poisoning in addition to this code.
