Toxic effect of metals, accidental (unintentional), sequela

This code signifies the long-term or residual effects resulting from an accidental poisoning by a metallic substance other than those specifically classified elsewhere (e.g., lead, mercury, arsenic). These sequelae are persistent health problems that manifest after the acute toxic event has resolved. Examples include chronic organ damage, neurological deficits, or ongoing systemic dysfunction.

Use this code when documenting a patient presenting with a current health condition that is a direct consequence of a past, unintentional exposure to an unlisted metal. This applies when the acute phase of the poisoning has passed, and the patient is now being treated for the lasting complications. It should not be used for the initial acute poisoning event.

• Always assign an additional code(s) to specify the nature of the sequela (e.g., specific organ damage, neurological condition).
• Ensure the documentation clearly links the current condition to a past accidental toxic exposure to an "other metal."
• Do not use this code for acute poisoning; reserve it strictly for the residual effects.
