Poisoning by enzymes, intentional self-harm, init encntr

This code signifies a patient presenting with adverse effects resulting from the deliberate ingestion or exposure to an enzyme, with the explicit intent of causing self-harm. The patient is in the acute phase of treatment for this poisoning.

Apply this code when documenting an initial encounter for a patient who has intentionally poisoned themselves with an enzyme, such as pancreatic enzymes or thrombolytic agents, and is receiving active treatment. This would include emergency department visits, initial hospital admissions, or the first outpatient visit for this specific incident.

• Ensure documentation clearly states "intentional self-harm" and identifies the substance as an enzyme.
• Confirm this is the initial encounter for the poisoning event; subsequent care would use a different seventh character.
• Always code the specific enzyme if known, using additional codes for manifestations of the poisoning.
