Toxic effect of arsenic and its compounds, assault, subs

This code signifies a patient presenting for follow-up care or treatment of adverse health effects resulting from intentional poisoning by arsenic or its compounds. The exposure was non-accidental and intended to cause harm, and the current encounter is for ongoing management of the toxic effects.

Use this code for subsequent encounters where a patient is receiving ongoing medical care for conditions directly attributable to an arsenic assault. This includes follow-up appointments for chelation therapy, monitoring of organ damage (e.g., renal, hepatic, neurological), or management of chronic symptoms stemming from the initial poisoning.

• Ensure documentation clearly indicates an "assault" as the intent of the arsenic exposure.
• This "D" seventh character is for subsequent encounters; use "A" for initial encounters and "S" for sequelae.
• Always code any specific manifestations of the arsenic toxicity (e.g., acute kidney failure, peripheral neuropathy) in addition to this code.
