In anesthesia services, how is one unit of time defined according to the AMA and ASA?

In anesthesia services, one unit of time is defined as 15 minutes of anesthesia time, as established by the American Medical Association (AMA) and the American Society of Anesthesiologists (ASA). This standardized definition is crucial because it ensures consistency in billing practices and allows for accurate reimbursement for services provided. Anesthesia time is typically calculated based on the length of time that the anesthesia provider is involved in the care of the patient, starting from the moment the anesthetic is administered until the patient is ready for transfer to post-anesthesia care. Understanding this unit of measurement is essential for healthcare professionals involved in anesthesia billing and coding, as it directly impacts the determination of total units billed for a patient’s anesthesia care.
