CPT code 01484: Bone procedure anesthesia, open lower leg, ankle, or foot2026 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 01484 covers

Code 01484 applies to anesthesia for open osteotomy or osteoplasty involving bones of the lower leg, ankle, or foot. Osteotomy cuts bone, often to alter alignment; osteoplasty reshapes bone. Orthopedic and podiatric surgeons may perform these operations. The anesthesia practitioner reports the anesthesia service for the operation.

Select this code when the operative report supports an open approach and osteotomy or osteoplasty at one of these sites. Use 01480 for other open lower-leg, ankle, or foot procedures without that specificity; 01482 identifies radical resection, and 01486 applies to open total ankle replacement. The operative report should establish the site, approach, and bone procedure, while the anesthesia record supports the service and its start and stop times. Medicare payment uses 4 base units plus time units, multiplied by the locality’s anesthesia conversion factor. Time is recorded in minutes and converted to 15-minute units to one decimal place, beginning with anesthesia preparation and ending when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care; the conversion factor varies by locality.

How to choose

01480Open lower-extremity anesthesiaLower leg, ankle, or foot

01484 is specific to open osteotomy or osteoplasty. Choose 01480 for other open lower-leg, ankle, or foot procedures that do not fit that bone-work category.

01482Radical resection anesthesiaLower leg, ankle, or foot

01482 is for radical resection in these regions; 01484 is for open osteotomy or osteoplasty.

01486Ankle replacement anesthesiaOpen total joint replacement

01486 applies to open total ankle replacement, not an osteotomy or osteoplasty merely because it involves ankle bones.

01462Closed lower-leg anesthesiaLower leg, ankle, or foot

01462 covers closed lower-leg, ankle, or foot procedures. Use 01484 for qualifying bone work performed through an open approach.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
