Poisoning by intravenous anesthetics, accidental, subs

This code signifies an adverse event where a patient has experienced harm due to an accidental overdose or incorrect administration of an intravenous anesthetic. The "subsequent encounter" indicates that the patient is receiving follow-up care for the initial poisoning, such as monitoring, further treatment, or management of complications.

This code is appropriate for documenting ongoing care for a patient who previously suffered unintentional poisoning from an IV anesthetic. Examples include a patient returning for a check-up after being discharged from the emergency department for an accidental propofol overdose, or a patient receiving ongoing treatment for organ damage resulting from an accidental fentanyl administration.

• Always ensure the "D" for subsequent encounter is appropriate; initial encounters would use "A".
• Verify the anesthetic was administered intravenously and that the poisoning was accidental.
• Code any resulting adverse effects or complications of the poisoning in addition to this code.
