Toxic effect of unsp corrosive substance, self-harm, sequela

This code signifies a long-term consequence or complication arising from a self-inflicted poisoning by an unknown corrosive substance. It indicates that the patient is presenting for treatment of a condition directly related to the original intentional self-harm event, which involved a substance that caused chemical destruction of tissue.

Apply this code when documenting a sequela, such as esophageal stricture, chronic pain, or organ damage, that is a direct result of a past intentional self-poisoning with an unspecified corrosive agent. This code is appropriate when the acute phase of the poisoning has passed, and the patient is being treated for residual effects.

• Always sequence this code after the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past intentional self-harm by an unspecified corrosive.
• The "S" in the 7th character indicates sequela; do not use for initial or subsequent encounters for the acute poisoning.
