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

This code signifies the long-term or residual effects resulting from a deliberate act of self-poisoning with zinc or its compounds. These sequelae can manifest as chronic organ damage, neurological deficits, or persistent systemic issues that arise after the acute toxic event has passed.

Apply this code when documenting conditions that are a direct consequence of a past intentional zinc poisoning, and the patient is no longer in the acute phase of toxicity. This is appropriate for follow-up encounters addressing chronic complications such as kidney damage, liver dysfunction, or neurological impairment attributed to the self-harm incident.

• Always sequence this sequela code after the code for the specific residual condition (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to a past intentional zinc poisoning.
• Do not use this code for acute zinc toxicity; it is exclusively for sequelae.
