Poisoning by antitussives, accidental, sequela

This code signifies a long-term health condition or complication arising from an accidental overdose or exposure to antitussive medications. It indicates that the acute poisoning event has resolved, but the patient continues to experience residual effects or chronic issues directly attributable to that past incident.

Apply this code when documenting a patient presenting with persistent neurological deficits, organ damage, or other chronic sequelae following an unintentional antitussive poisoning. This would be used for follow-up visits where the primary focus is managing these lasting complications, not the acute poisoning itself.

• Always sequence this code after the code for the specific sequela (e.g., a code for chronic liver damage).
• Ensure documentation clearly links the current condition to a past accidental antitussive poisoning.
• Do not use this code for acute poisoning events; use the appropriate acute poisoning code for the initial encounter.
