This code signifies a patient presenting for follow-up care or treatment of residual effects after an accidental carbon monoxide poisoning event. The poisoning specifically resulted from the incomplete combustion of various household fuels, excluding utility gas, motor vehicle exhaust, or other specified sources. The patient is no longer in the acute phase of the poisoning.

Apply this code when documenting subsequent care for a patient who previously experienced accidental carbon monoxide poisoning from sources like wood stoves, kerosene heaters, or charcoal grills. This includes visits for ongoing symptom management, monitoring for long-term neurological or cardiac complications, or rehabilitation services related to the initial exposure.

• Ensure the documentation clearly states the accidental nature of the exposure and the specific fuel source (e.g., wood-burning fireplace, propane heater).
• Confirm this is a subsequent encounter, not the initial treatment for the acute poisoning.
• Look for documentation of persistent symptoms or complications directly attributable to the past carbon monoxide exposure.
