Toxic effect of hydrogen sulfide, self-harm, init

This code signifies a patient presenting with adverse health effects resulting from deliberate exposure to hydrogen sulfide, with the intent to harm oneself. The patient is in the initial phase of receiving active treatment for this toxic exposure.

Apply this code for emergency department visits or initial hospital admissions where a patient has intentionally inhaled or otherwise been exposed to hydrogen sulfide gas in a suicide attempt. This would also be appropriate for the initial outpatient evaluation and management of such an event.

• Ensure documentation clearly states the intentional nature of the exposure (e.g., "suicide attempt," "self-inflicted").
• Confirm the substance involved is specifically hydrogen sulfide.
• Verify this is the first encounter for this specific toxic event; subsequent encounters would use a different seventh character.
