Poisoning by benzodiazepines, accidental, sequela

This code signifies the long-term or residual effects resulting from an accidental overdose or unintentional exposure to benzodiazepine medications. These sequelae are the lasting health problems or conditions that persist after the acute phase of the poisoning has resolved.

Apply this code when documenting chronic neurological deficits, organ damage, or other persistent health issues directly attributable to a past accidental benzodiazepine poisoning. This is appropriate for follow-up encounters where the patient is being treated for the lasting consequences, not the acute poisoning itself.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic encephalopathy).
• Ensure documentation clearly links the current condition to a past accidental benzodiazepine poisoning.
• Do not use for acute poisoning events; use the appropriate acute poisoning code for those encounters.
