Toxic effect of carb monx from oth source, assault, sequela

This code signifies the long-term or residual effects resulting from carbon monoxide poisoning that occurred due to an intentional act of harm by another person. These sequelae are the lasting health problems that persist after the initial acute phase of the poisoning has resolved.

Apply this code when documenting chronic neurological, cardiac, or other organ damage directly attributable to a past carbon monoxide exposure that was inflicted as an assault. This would be used for follow-up care or ongoing management of these persistent conditions.

• Always sequence this code after the code(s) identifying the specific sequela (e.g., specific neurological deficit).
• Ensure documentation clearly links the current condition to a past carbon monoxide poisoning event that was an assault.
• Do not use for acute carbon monoxide poisoning; this code is exclusively for the late effects.
