Toxic effect of mercury and its compounds, assault, sequela

This code signifies the long-term or residual health problems resulting from a past poisoning by mercury or its compounds, specifically when the poisoning was due to an intentional act of harm by another person. These sequelae can manifest in various organ systems, including neurological, renal, and gastrointestinal.

Apply this code when documenting chronic conditions or persistent symptoms directly attributable to a previous mercury poisoning that occurred as a result of an assault. This would include situations where a patient presents with ongoing tremors, cognitive deficits, or kidney damage years after an intentional mercury exposure by another individual.

• Always sequence this sequela code after the code for the specific manifestation of the mercury poisoning.
• Ensure documentation clearly links the current condition to a past mercury exposure and specifies the assault as the external cause.
• Do not use this code for acute mercury poisoning or for poisonings due to accidental or self-harm intent.
