Toxic effect of arsenic and its compounds

This code signifies the adverse health effects resulting from exposure to arsenic or its various chemical compounds. It covers both acute and chronic manifestations of arsenic poisoning, affecting multiple organ systems. The toxic effects can range from gastrointestinal distress and dermatological changes to neurological damage and systemic organ failure.

Apply this code when documentation clearly indicates a patient's signs, symptoms, or confirmed diagnosis are directly attributable to arsenic toxicity. This includes occupational exposures, accidental ingestions, environmental contamination, or intentional poisoning. Supporting documentation should detail the source of exposure, clinical presentation, and diagnostic findings confirming arsenic's role.

• Distinguish between accidental poisoning (E860.0-E860.9) and therapeutic misadventure (E850.0-E858.9) when assigning E-codes for external causes.
• Always sequence this code as the principal diagnosis when it is the primary reason for the encounter, followed by codes for specific manifestations of the toxicity.
• Do not use this code for prophylactic measures or screening for arsenic exposure without evidence of toxic effects.
