What 01925 covers
This code covers anesthesia for therapeutic interventional radiology procedures that treat disease in the carotid or coronary arteries. Typical cases include catheter-based treatment of carotid narrowing or coronary arterial disease in an interventional radiology or catheterization setting. An anesthesia physician or qualified anesthesia practitioner reports the service based on the anesthesia provided for the intervention.
Choose this code for carotid or coronary arterial treatment, not diagnostic-only arteriography, treatment of other arteries, or procedures involving intracranial, intracardiac, or aortic targets. The anesthesia record should support the practitioner’s attendance and elapsed anesthesia time; the procedure record should identify the therapeutic intervention and the treated artery. Medicare payment is (7 base units + time units) × the locality’s anesthesia conversion factor; time is counted in minutes and converted to 15-minute units to one decimal place, from preparation for anesthesia until personal attendance ends and the patient can safely be placed under postoperative care.
