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

This code signifies a lasting health problem or condition that resulted from a deliberate act of self-poisoning with an unknown inorganic substance. The patient experienced a toxic effect from a non-organic compound, and the original self-harm event has since resolved, leaving behind a chronic or residual issue.

Apply this code when documenting a current, long-term consequence of a past intentional self-harm attempt involving an unspecified inorganic substance. This is appropriate for follow-up encounters where the acute poisoning has been treated, but the patient continues to suffer from sequelae directly attributable to that event.

• Ensure documentation clearly links the current sequela to a past intentional self-harm event involving an inorganic substance.
• Only use this code when the specific inorganic substance is unknown or not documented.
• The "S" in the seventh character indicates sequela, meaning the initial injury or poisoning has healed, but a residual condition persists.
