Tox eff of carb monx fr incmpl combst dmst fuel,slf-hrm,init

This code signifies a poisoning or adverse reaction resulting from carbon monoxide exposure, specifically when the source is incomplete combustion of domestic fuels other than utility gas or motor vehicle exhaust. The exposure is explicitly identified as an intentional act of self-harm.

Apply this code for patients presenting with symptoms of carbon monoxide poisoning where the history clearly indicates a deliberate attempt to self-harm using a non-utility domestic fuel source (e.g., charcoal grill indoors, kerosene heater) and it's the initial treatment for this specific event. This would be used in emergency department visits or initial hospital admissions following such an incident.

• Always confirm the intent (intentional self-harm) and the specific carbon monoxide source (incomplete combustion of other domestic fuels).
• Remember the "A" at the end signifies an initial encounter for this condition. Subsequent care would use a different seventh character.
• Code any associated physical injuries or mental health diagnoses separately.
