Poisoning by antiviral drugs, accidental, sequela

This code signifies a long-term consequence or complication arising from an accidental overdose or improper administration of an antiviral medication. The initial poisoning event has resolved, but the patient is now experiencing residual effects directly attributable to that past exposure.

Apply this code when documenting a current condition that is a permanent or chronic sequela of a previous, unintentional antiviral drug poisoning. This would be used for follow-up care or management of these lasting effects, not for the acute poisoning event itself.

• Always sequence the code for the specific sequela (e.g., kidney failure, neuropathy) first, followed by this sequela code.
• Ensure documentation clearly links the current condition to a past accidental antiviral poisoning.
• This code is for unintentional poisonings; intentional self-harm or assault would require different codes.
