Poisoning by unsp topical agent, self-harm, sequela

This code signifies a long-term consequence or complication arising from a deliberate act of self-poisoning using an unspecified topical agent. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing residual effects directly attributable to that past event. These sequelae could range from chronic skin conditions to systemic issues.

Apply this code when documenting a patient presenting with a current health problem that is a direct result of a previous intentional self-harm attempt involving an unknown topical substance. This is appropriate for follow-up encounters where the focus is on managing the lasting impact of the poisoning, rather than the acute event itself. Examples include chronic dermatitis, scarring, or organ damage identified months or years after the initial incident.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past intentional self-harm event involving a topical agent.
• Avoid using this code for acute poisoning events; the "S" seventh character indicates a sequela.
