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.
01484 billing questions
How does 01484 differ from 01480?
Use 01484 when the open lower-leg, ankle, or foot operation specifically involves an osteotomy or osteoplasty. Code 01480 is the broader choice for other open procedures in those regions.
Does 01484 cover ankle replacement?
No. Open total ankle replacement has its own anesthesia code, 01486.
Can I use 01484 for a closed lower-extremity procedure?
No. Code 01484 is for open bone procedures. Code 01462 describes anesthesia for closed procedures on the lower leg, ankle, or foot.
What documentation supports reporting 01484?
The operative report should identify the open approach, the lower-leg, ankle, or foot site, and the osteotomy or osteoplasty performed. The anesthesia record should support the service and its start and stop times.
How are Medicare time units calculated?
Report anesthesia time in minutes; CMS converts it to 15-minute units, calculated to one decimal place. Time begins with patient preparation for anesthesia and ends when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.
Is the surgeon’s bone procedure included in this anesthesia code?
No. This code identifies the anesthesia service; the surgeon reports the operative procedure separately.
