Toxic effect of sulfur dioxide, undetermined, init encntr

This code signifies an adverse health effect resulting from exposure to sulfur dioxide, where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined from the available documentation. The patient is presenting for the initial treatment of this toxic effect.

Apply this code when a patient presents with symptoms or signs of sulfur dioxide poisoning, and the medical record does not specify whether the exposure was accidental, intentional, or due to assault. This code is appropriate for the very first encounter for this specific toxic event.

• Ensure documentation clearly states sulfur dioxide as the causative agent.
• Confirm that the intent of exposure is explicitly "undetermined" in the medical record.
• Verify this is the patient's initial visit for this particular toxic effect.
