Toxic effect of copper and its compounds, self-harm, sequela

This code signifies the long-term or residual effects resulting from a deliberate act of self-poisoning with copper or its compounds. It indicates that the patient previously ingested or was exposed to copper with the intent to harm themselves, and they are now presenting with persistent health issues directly attributable to that past event.

Use this code when documenting chronic or permanent health problems, such as liver damage, kidney dysfunction, or neurological deficits, that are a direct consequence of a prior intentional copper poisoning. This applies even if the acute poisoning event occurred months or years ago, and the patient is no longer acutely toxic.

• Always sequence this code after the code(s) for the specific sequelae (e.g., chronic hepatitis, renal failure) being treated.
• Do not use this code for acute copper poisoning or for accidental/unintentional exposures; different codes apply for those scenarios.
• Ensure documentation clearly links the current sequela to a past intentional self-harm event involving copper.
