Poisoning by anthelminthics, intentional self-harm, init

This code signifies a patient presenting with adverse effects resulting from the deliberate ingestion or administration of an anthelminthic medication with the intent to cause self-harm. The patient is in the acute phase of treatment for this poisoning.

Apply this code when a patient is admitted to the emergency department or hospital for an overdose of an anthelminthic drug, and medical documentation clearly indicates the act was intentional self-harm. This is appropriate for the initial encounter where the patient is receiving active treatment for the poisoning.

• Always sequence this code first when it represents the primary reason for the encounter.
• Requires an additional code for the specific anthelminthic drug (e.g., from T37.4X1-T37.4X4).
• Do not use for accidental poisoning or adverse effects from therapeutic use.
