Poisoning by intravenous anesthetics, undetermined, sequela

This code signifies a poisoning event involving intravenous anesthetics where the intent (accidental, intentional self-harm, assault) cannot be determined. It specifically indicates that the patient is experiencing a sequela, meaning a residual condition or complication resulting from the initial poisoning. This is not for the acute phase of the poisoning.

Apply this code when documentation clearly states a patient is presenting with a long-term effect or complication directly attributable to a past, undetermined poisoning by an IV anesthetic. This would be used in follow-up encounters after the acute poisoning has resolved, but the patient continues to suffer from its after-effects.

• Always assign an additional code(s) to specify the nature of the sequela (e.g., neurological damage, organ dysfunction).
• Ensure the medical record explicitly states "undetermined" intent for the poisoning; otherwise, a more specific intent code should be used.
• Verify that the encounter is for a residual condition and not the acute poisoning episode, which would require an acute poisoning code.
