Toxic effect of inorganic substances, self-harm, sequela

This code signifies a long-term health problem or complication resulting from a deliberate act of self-poisoning with an inorganic substance not specifically classified elsewhere. It indicates that the acute toxic event is no longer active, but its lasting effects are still present and require ongoing management.

Apply this code when documenting chronic organ damage, neurological deficits, or other persistent health issues directly attributable to a past intentional self-harm attempt involving an inorganic substance. This is appropriate for follow-up encounters where the sequelae, not the acute poisoning, are the primary focus of care.

• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease, peripheral neuropathy).
• Ensure documentation clearly links the current condition to a past intentional self-harm event involving an inorganic substance.
• Do not use for acute poisoning events; this code is exclusively for the residual effects.
