Poisoning by other topical agents, assault, sequela

This code signifies a long-term health problem or complication resulting from an intentional act of harm involving the application of a topical agent to a person. The initial poisoning was an assault, and the patient is now experiencing residual effects or conditions directly attributable to that event. This could include chronic skin conditions, organ damage, or neurological issues that developed after the acute phase of the poisoning.

Apply this code when documenting a current condition that is a direct consequence of a past assault involving a topical agent. This is appropriate for follow-up encounters where the sequela is being treated or monitored, and the acute poisoning event has resolved. Examples include chronic dermatitis from a chemical burn inflicted during an assault, or persistent neurological deficits from a neurotoxic topical agent used in an assault.

• Always sequence this code after the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past assault by a topical agent.
• Do not use for acute poisoning events; this code is exclusively for residual effects.
