Toxic effect of sulfur dioxide, intentional self-harm, init

This code signifies a patient presenting with adverse health effects resulting from the deliberate ingestion, inhalation, or exposure to sulfur dioxide with the intent to harm oneself. The "initial encounter" indicates that this is the first time the patient is receiving active treatment for this specific poisoning.

Apply this code when documenting a patient admitted to the emergency department or hospital following a suicide attempt involving sulfur dioxide. This includes cases where the patient explicitly states self-harm intent or when clinical evidence strongly suggests intentional exposure.

• Always sequence this code first when it represents the primary reason for the encounter.
• Requires an additional code for the manifestation of the toxic effect (e.g., respiratory failure, chemical burns).
• Do not use for accidental or unintentional exposure; a different intent character is required for those scenarios.
