CPT code 01770: Arterial anesthesia, upper arm and elbow2026 Medicare rate & RVUs in Florida

CMS doesn’t publish an office rate for 01770 in Florida.

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

What 01770 covers

01770 applies to anesthesia for operations on arteries in the upper arm or elbow when no more specific anesthesia category identifies the arterial procedure. An anesthesia practitioner, such as an anesthesiologist or CRNA, reports the anesthesia service; the code is selected for the arterial operative target, not simply because an incision is near the elbow. Arterial embolectomy is assigned to 01772, which describes removal of an embolus.

The operative report should identify the artery treated and the procedure performed, and the anesthesia record should support the anesthesia service and its start and end times. Use a neighboring anesthesia code when its defined procedure category matches, such as 01780 for upper-arm or elbow venous procedures. Medicare calculates payment as (base units + time units) × the locality’s anesthesia conversion factor; 01770 has 6 base units. Anesthesia time runs from when the practitioner begins preparing the patient until the practitioner is no longer personally attending and the patient can safely be placed under postoperative care; minutes convert to 15-minute units computed to one decimal place, and the conversion factor varies by locality.
