Which modifier represents monitored anesthesia care service?

The modifier that represents monitored anesthesia care services is the QS modifier. This modifier is used to indicate that the anesthetic care provided involved monitoring of the patient's vital signs and level of sedation. Monitored anesthesia care is an anesthesia service that includes the administration of anesthesia and monitoring of the patient throughout the surgical or procedural process. The QS modifier specifically signals that the services were not just a basic administration of anesthesia but involved significant monitoring, which is crucial for safety during procedures.

Using the QS modifier helps ensure that the facility receives proper reimbursement for the increased level of care provided. Proper documentation and the appropriate use of modifiers are essential for accurately reflecting the services rendered and supporting compliance with coding guidelines.
