Poisoning by arsenical anti-infectives

This code signifies an adverse health effect resulting from exposure to or ingestion of anti-infective medications containing arsenic. It describes the toxicological impact of these specific pharmaceutical agents on the patient's system.

Use this code when documentation clearly indicates a patient has experienced poisoning due to an arsenical anti-infective, whether from accidental ingestion, overdose, or adverse reaction. Supporting documentation should detail the substance involved and the resulting toxic effects.

• Always code the specific manifestation of the poisoning (e.g., acute renal failure, hepatic necrosis) as a primary diagnosis, with this code as a secondary diagnosis.
• Distinguish carefully from adverse effects of non-arsenical anti-infectives, which would fall under different categories.
• Ensure documentation specifies "arsenical anti-infective" rather than just "arsenic" to justify this specific code.
