Poisoning by diagnostic agents, assault, subs encntr

This code signifies a poisoning event resulting from the intentional administration of a diagnostic agent with the intent to harm, where the patient is receiving follow-up care for the sequelae of the initial poisoning. This includes ongoing treatment, monitoring, or evaluation of complications arising from the assault.

Use this code for patients presenting for subsequent treatment of adverse effects or injuries sustained from a diagnostic agent administered during an assault. This applies to scenarios such as a patient returning for renal failure management after being intentionally poisoned with a contrast dye, or for neurological complications following an assault involving a radiopharmaceutical.

• Ensure documentation clearly states the poisoning was due to a diagnostic agent and was an assault.
• This code is for subsequent encounters; for the initial encounter, use the appropriate "A" seventh character.
• Always code the specific adverse effect or complication resulting from the poisoning first, followed by this code.
