Toxic effect of arsenic and its compnd, self-harm, sequela

This code indicates the long-term or residual effects resulting from a deliberate act of self-poisoning with arsenic or its compounds. These sequelae can manifest as chronic organ damage, neurological deficits, or other lasting health problems that developed after the acute toxic event. The original intent was self-harm, and the current condition is a direct consequence of that prior exposure.

Apply this code when documenting a patient presenting with a chronic condition or permanent disability directly attributable to a past intentional self-poisoning with arsenic. This code is appropriate for follow-up encounters where the acute phase of the poisoning has resolved, but the patient continues to experience related health issues. It signifies that the current problem is a late effect of the initial self-inflicted arsenic toxicity.

• Always sequence this sequela code after the code for the specific manifestation of the chronic arsenic poisoning (e.g., chronic kidney disease, peripheral neuropathy).
• Ensure documentation clearly links the current condition to a past intentional self-harm event involving arsenic.
• Do not use this code for acute arsenic poisoning or for accidental or assault-related exposures.
