Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult admitted to an inpatient hospital for surgery on the thoracic spine and spinal cord. The patient may present with symptoms such as back pain, neurological deficits, or myelopathy due to conditions like spinal stenosis or intervertebral disc disorders. The anesthesiology team provides anesthesia services for the procedure, ensuring patient safety and comfort throughout the surgical intervention. The clinical workflow includes preoperative assessment, administration of anesthesia, intraoperative monitoring, and postoperative care, often coordinated by anesthesiologists or certified registered nurse anesthetists (CRNAs) under physician direction.

Modifiers:
QS: Monitored anesthesia care service. Used when the anesthesia provider delivers monitored anesthesia care rather than general anesthesia.QX: CRNA service with medical direction by a physician. Used when a CRNA provides anesthesia services under the medical direction of a physician.
