Pers hx of unintended awareness under general anesthesia

This code signifies a patient's past experience of being conscious or aware during a surgical procedure performed under general anesthesia, despite the intention for them to be fully unconscious. This condition, often referred to as "anesthesia awareness," can involve recall of events, sensations, or even pain during the operation.

Use this code when documenting a patient's self-reported or medically confirmed history of unintended awareness under general anesthesia. This is relevant for pre-operative assessments, risk stratification for future procedures, and when managing psychological sequelae related to such an event.

• This code is for a personal history of the event, not for an acute occurrence.
• Do not use this code if the unintended awareness occurred during the current encounter; refer to the Excludes2 note.
• Consider additional codes for any associated mental health conditions (e.g., PTSD, anxiety) if documented.
