What 00350 covers
This service covers anesthesia for surgery on major blood vessels in the neck, commonly carotid operations such as carotid endarterectomy. An anesthesiologist or CRNA may report it for hospital or other surgical-facility care. The anesthesia record should identify the anesthesia practitioner and document the care provided; the operative report should establish the major neck vessel treated and the procedure performed.
Choose this code for major-vessel neck surgery rather than general neck procedures or simple vessel ligation. Carotid endarterectomy, commonly reported with CPT 35301, is a typical pairing. Medicare payment is (10 base units + time units) multiplied by the locality’s anesthesia conversion factor. Anesthesia time is reported in minutes and converted to 15-minute units to one decimal place; it begins when the practitioner starts preparing the patient for anesthesia and ends when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.
