Toxic effect of carb monx from utility gas, slf-hrm, sequela

This code signifies the long-term or residual effects resulting from a deliberate act of self-harm involving carbon monoxide poisoning specifically originating from utility gas. These sequelae can manifest as neurological deficits, cognitive impairment, or other chronic health issues that persist after the initial acute poisoning event has resolved.

Apply this code when documenting a patient presenting with persistent health problems directly attributable to a past intentional self-harm attempt using carbon monoxide from utility gas. This would be used for follow-up care or rehabilitation services addressing the lasting consequences of such an event, not for the initial acute poisoning.

• Always sequence this sequela code after the code describing the specific nature of the sequela (e.g., a neurological condition).
• Ensure documentation clearly links the current condition to a past intentional carbon monoxide poisoning from utility gas.
• Verify the "S" seventh character is appropriate for sequela, indicating a late effect.
