Toxic effect of unsp metal, accidental, sequela

This code signifies a long-term or residual health problem resulting from an accidental exposure to an unspecified metal. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing a chronic or lasting effect due to the initial unintentional toxic exposure.

Apply this code when documenting a sequela (late effect) of an accidental poisoning by a metal that is not specified further. This would be appropriate for conditions like chronic neurological deficits or organ damage attributed to a past, unintentional metal exposure, where the specific metal involved was never identified.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure the documentation clearly states the metal exposure was accidental and that the current condition is a residual effect.
• Avoid using this code if the specific metal is known; instead, use the more precise code for that metal's toxic effect.
