Clinical & Coding Specifications

Clinical Context

A typical patient scenario involves an adult admitted to an inpatient hospital for a surgical procedure on the upper leg, excluding the knee. The patient may have a history of osteoarthritis or previous knee replacement, but the surgery is focused on the upper leg (such as the thigh or femur) rather than the knee joint. An anesthesiologist or certified registered nurse anesthetist (CRNA) provides anesthesia services to ensure the patient is safely sedated and pain-free during the procedure. The clinical workflow includes preoperative assessment, administration of anesthesia, intraoperative monitoring, and postoperative care in the hospital setting.

Coding Specifications

Modifier QS: Indicates a monitored anesthesia care service. Used when the anesthesia provider is present and monitoring the patient, but not providing general anesthesia.
Modifier QX: Used when a CRNA is providing anesthesia services with medical direction by a physician.
