§9789.18.10. Anesthesia - Monitored Anesthesia Care.

The physician or non-physician practitioner shall be reimbursed for reasonable and medically necessary monitored anesthesia care services on the same basis as other anesthesia services. Anesthesiologists use modifier QS to report monitored anesthesia care cases. Monitored anesthesia care involves the intra-operative monitoring by a physician or qualified individual under the medical direction of a physician or of the patient's vital physiological signs in anticipation of the need for administration of general anesthesia or of the development of adverse physiological patient reaction to the surgical procedure. It also includes the performance of a pre-anesthetic examination and evaluation, prescription of the anesthesia care required, administration of any necessary oral or parenteral medications (e.g., atropine, demerol, valium) and provision of indicated postoperative anesthesia care. Payment is made under the fee schedule using the payment rules in section 9789.18.2 if the physician personally performs the monitored anesthesia care case or under the rules in section 9789.18.3 if the physician medically directs four or fewer concurrent cases and monitored anesthesia care represents one or more of these concurrent cases.
