CPT code 01924: Arterial intervention, other arterial sites2026 Medicare rate & RVUs

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 01924 covers

This service covers anesthesia for therapeutic procedures performed through image-guided access to arteries, typically in an angiography or interventional radiology suite. Examples include peripheral arterial angioplasty, stent placement, and arterial embolization when the procedure does not fit a more specifically coded arterial site. An anesthesiologist or CRNA reports the anesthesia service for the patient undergoing the intervention.

Use this code for arterial targets outside the more specific categories for the carotid artery and for intracranial, intracardiac, or aortic procedures; it is not the code for therapeutic venous interventions. The anesthesia record and operative report should identify the artery treated, the therapeutic procedure, and the anesthesia practitioner’s attendance and times. Medicare assigns 5 base units; payment is (base units plus time units) multiplied by the locality’s anesthesia conversion factor. Time is reported in minutes and converted to 15-minute units to one decimal place, starting when the practitioner begins preparing the patient for anesthesia and ending when the practitioner is no longer personally attending and the patient can safely be placed under postoperative care.
