Summary & Overview
CPT 01520: Anesthesia for Procedures on Veins of the Lower Leg
CPT code 01520 designates anesthesia services for procedures on the veins of the lower leg. As an anesthesia billing code, it captures perioperative anesthetic management specifically tied to venous interventions below the knee, a common component of vascular and general surgical workflows. Accurate use of this code supports appropriate tracking of anesthesia utilization and payment for procedures that address venous disease and related complications.
Key national payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. The publication provides readers with context on clinical indications and settings for the code, comparisons across major payers, and operational considerations relevant to billing teams and anesthesia providers. It highlights common billing scenarios and how this anesthesia descriptor maps to lower-leg venous procedures performed in hospitals and ambulatory surgical centers.
Readers will learn: the clinical scope of CPT code 01520; which major payers are relevant for coverage considerations; how the code fits into anesthesia service lines; and linked codes and diagnoses typically encountered in venous procedure cases. Data not available in the input is identified where relevant. The focus is national in scope and intended for coding, billing, and anesthesia clinical management audiences.

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with symptomatic knee osteoarthritis presents for a planned lower leg vein procedure under anesthesia. The patient has a history of unilateral primary osteoarthritis of the right knee (M17.11) and a right total knee arthroplasty (Z96.651). The treating vascular surgeon schedules endovenous ablation of the great saphenous vein below the knee for symptomatic varicose veins refractory to conservative therapy. Preoperative evaluation by the anesthesia team documents cardiovascular and pulmonary assessment, medication reconciliation, and ASA physical status P3 due to controlled ischemic heart disease and fixed functional limitation from knee osteoarthritis. On the day of service, the anesthesia provider (physician anesthesiologist or Certified Registered Nurse Anesthetist) administers regional anesthesia (e.g., peripheral nerve block or monitored anesthesia care with sedation) and monitors the patient through the procedure in an outpatient ambulatory surgery center. Postprocedural handoff includes post-anesthesia recovery monitoring and documentation of anesthesia time and any intraoperative events affecting billing (e.g., unplanned intensive care transfer or significant anesthesia-related complication).
