Poisoning by intravenous anesthetics, accidental, sequela

This code signifies a long-term or residual effect resulting from an accidental overdose or adverse reaction to an intravenous anesthetic agent. These sequelae are persistent conditions that manifest after the initial acute phase of poisoning has resolved. Examples include chronic neurological deficits, organ damage, or other lasting complications directly attributable to the prior anesthetic poisoning.

Apply this code when documenting a patient presenting with a current condition that is a direct, lasting consequence of an accidental intravenous anesthetic poisoning that occurred in the past. This is appropriate for follow-up visits or admissions where the focus is on managing these chronic complications, not the acute poisoning event itself. Do not use for the initial acute poisoning.

• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease, neuropathy).
• Ensure documentation clearly links the current condition to a past accidental intravenous anesthetic poisoning.
• Verify the "S" seventh character is appropriate, indicating a sequela, and not an initial encounter (A) or subsequent encounter (D).
