Toxic effect of unsp gases, fumes and vapors, slf-hrm, init

This code signifies a patient presenting with adverse health effects resulting from deliberate self-poisoning via an unknown or unidentifiable gaseous, fume, or vapor substance. The patient intentionally exposed themselves to the substance with the intent to cause harm.

Apply this code when documentation clearly indicates a toxic effect from an unspecified inhaled substance, and the patient explicitly states or clinical evidence strongly suggests the exposure was a deliberate act of self-harm. This code is appropriate for the initial treatment of such an event.

• Ensure documentation specifies "intentional self-harm" and an "unspecified" gas, fume, or vapor.
• Do not use if the specific substance is known; instead, code to the specific toxic agent.
• Always assign an additional code for the patient's mental health condition (e.g., depression, suicidal ideation) if documented.
