CPT Code Overview
CPT code 01444 is used to report anesthesia services for procedures performed on arteries of the knee and popliteal area. This code falls under the anesthesiology service type and is typically utilized in an inpatient hospital setting (Place of Service 21). The code is relevant for cases where specialized anesthesia care is required to support surgical interventions involving the vascular structures around the knee.
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult admitted to an inpatient hospital for a surgical procedure on the arteries of the knee or popliteal area. The patient may have a history of unilateral primary osteoarthritis of the knee, or may have a prior knee arthroplasty. The clinical workflow includes preoperative assessment by the anesthesiology team, administration of anesthesia specific to vascular procedures in the knee region, intraoperative monitoring, and postoperative care. Anesthesia services are provided by either an anesthesiology physician or a certified registered nurse anesthetist (CRNA), often in collaboration with an orthopaedic surgeon performing the procedure.

Modifiers:
QS: Monitored anesthesia care service. Used when anesthesia is provided in a manner that allows the patient to remain responsive and breathing independently.QX: CRNA service with medical direction by a physician. Used when a CRNA provides anesthesia under the supervision of an anesthesiology physician.
