Toxic effect of arsenic and its compounds, assault, sequela

This code signifies the long-term, residual effects resulting from an intentional poisoning by arsenic or its compounds. These sequelae represent chronic health problems directly attributable to a past assault involving arsenic exposure. The initial acute toxic effects have resolved, but lasting damage persists.

Apply this code when documenting chronic conditions or disabilities that are a direct consequence of a previous arsenic poisoning where the intent was assault. This is appropriate for follow-up encounters addressing these persistent health issues, rather than the initial acute poisoning event. Examples include chronic neurological deficits, kidney damage, or skin lesions proven to be from the past arsenic assault.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic kidney disease, peripheral neuropathy).
• Ensure documentation clearly links the current condition to a past arsenic assault and specifies the "sequela" nature of the presentation.
• Do not use this code for acute arsenic poisoning; refer to the appropriate acute toxic effect codes for initial encounters.
