Toxic effect of phenol and phenol homolog, assault, sequela

This code signifies a long-term health problem or complication arising from a past intentional poisoning by phenol or its related chemical compounds. The original exposure was a deliberate act of harm, and the patient is now experiencing residual effects from that event.

Assign this code when documenting a current condition that is a direct consequence of a previous assault involving phenol or phenol homologues. This applies to chronic or permanent sequelae, not acute poisoning. The assault must have occurred in the past, and the patient is presenting for treatment of the lasting effects.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., organ damage, neurological deficits).
• Ensure documentation clearly links the current condition to a past assault involving phenol or its derivatives.
• Do not use for acute poisoning; refer to the appropriate acute toxic effect codes for initial encounters.
