Toxic effect of unsp metal, intentional self-harm, sequela

This code describes the long-term or residual effects resulting from a patient's deliberate self-poisoning with an unknown metallic substance. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing chronic health issues directly attributable to that past event.

Use this code when documenting a patient presenting with persistent symptoms or conditions (e.g., neurological damage, organ dysfunction) that are a direct consequence of a previous, intentional self-harm attempt involving an unspecified metal. This code is appropriate for follow-up encounters after the initial acute poisoning has been treated.

• Requires a seventh character 'S' for sequela, indicating a late effect.
• Always sequence this code after the code(s) describing the specific sequela (e.g., peripheral neuropathy, chronic kidney disease).
• Only use when the specific metal involved in the self-harm is unknown or not documented.
