Poisoning by unspecified topical agent, assault, sequela

This code signifies a long-term health condition or complication resulting from an intentional poisoning by an unknown topical substance. The original poisoning event was inflicted by another person with the intent to harm. The sequela could manifest as chronic skin conditions, organ damage, or neurological impairments.

Use this code when documenting a current health problem directly attributable to a past assault involving an unspecified topical agent. This applies when the acute phase of the poisoning has resolved, but residual effects persist and require ongoing medical attention. It is appropriate when the specific topical agent used in the assault is not identified.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past assault by an unspecified topical agent.
• Avoid using this code for acute poisoning events; it is strictly for sequelae.
