Poisoning by oth drug/meds/biol subst, assault, subs

This code signifies a patient presenting with adverse effects from an intentional overdose or exposure to a drug, medication, or biological substance, where the intent was to harm the patient (assault). The patient is receiving follow-up care for the poisoning after the initial treatment.

Apply this code when documenting a patient's subsequent visit for ongoing management or complications related to a poisoning that was inflicted by another person. This includes follow-up appointments for organ damage, psychological sequelae, or persistent symptoms stemming from the initial assaultive poisoning.

• Ensure the documentation clearly states the poisoning was due to an assault and that this is a subsequent encounter.
• Always code the specific drug or substance involved if known, using additional codes from categories T36-T50.
• Do not use this code for accidental poisonings or self-harm; those scenarios require different intent codes.
