This code signifies the long-term or residual effects resulting from a deliberate act of self-harm involving carbon monoxide poisoning. The carbon monoxide exposure specifically originated from the incomplete combustion of household fuels other than utility gas or motor vehicle exhaust. These sequelae can include neurological deficits, cardiac issues, or other chronic health problems.

Assign this code when documenting a patient presenting with persistent health issues directly attributable to a past, intentional self-inflicted carbon monoxide poisoning event. The source of the carbon monoxide must be identified as domestic fuels like wood, coal, or kerosene, and not from a vehicle or utility gas. This code is used for the "S" (sequela) encounter type, indicating the long-term consequences of the initial injury.

• Always use this code as a secondary diagnosis, following a code for the specific sequela (e.g., a neurological disorder).
• Ensure documentation clearly specifies the intentional nature of the poisoning and the source as domestic fuels (excluding utility gas/vehicle exhaust).
• Do not use for acute poisoning events; this code is exclusively for the late effects or complications.
