Clinical & Coding Specifications
Clinical Context
A patient presents to the outpatient hospital with chronic nasal obstruction and sinus symptoms. After evaluation by an otolaryngologist, the patient is scheduled for a surgical procedure on the nose or accessory sinuses, such as septoplasty or sinus endoscopy. An anesthesiologist provides anesthesia services for the procedure, ensuring patient comfort and safety throughout. The anesthesia is administered in the outpatient hospital setting, and the patient is monitored during and after the procedure until stable for discharge.

QS: Indicates that monitored anesthesia care (MAC) was provided. Used when the anesthesiologist is present and monitoring the patient, but not providing general anesthesia. -
Modifier
P1: Denotes a normal healthy patient. Used to indicate the patient's physical status classification during anesthesia.
