About 29907: Arthroscopic subtalar joint fusion
Arthroscopic subtalar arthrodesis is reported when a surgeon prepares and fuses the subtalar joint through arthroscopic access.
An orthopedic foot and ankle surgeon uses arthroscopic portals to access the subtalar joint, prepare the joint surfaces for fusion, and stabilize the joint. The operation treats conditions for which subtalar fusion is indicated, such as painful arthritis or deformity involving the joint. It is generally performed in a hospital outpatient department or ambulatory surgery center; CMS recorded facility services for this code in 2024.
Report this code when the operative work includes arthroscopically performed subtalar arthrodesis, not merely diagnostic inspection or another subtalar arthroscopy procedure. The operative report should identify the joint and side, describe arthroscopic joint preparation and fusion, and document fixation and any graft used. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeons and team surgery are not permitted.

29907 billing questions
When should 29907 be selected instead of another subtalar arthroscopy code?
Use 29907 when the arthroscopic procedure includes fusion of the subtalar joint. Codes for removal of a loose body, excision, or debridement describe different operative work.
Is subtalar fusion reported with modifier 50 when both sides are treated?
CMS lists this as a bilateral procedure; bilateral reporting with modifier 50 is paid at 150%. Document the work performed on each side.
How does the multiple-procedure rule affect payment?
When other procedures are performed in the same session, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
What documentation supports reporting 29907?
The operative report should establish arthroscopic access, subtalar joint preparation for fusion, and the fusion performed. Include laterality and describe fixation and any graft used.
Can an assistant-at-surgery or co-surgeon be reported?
Assistant-at-surgery payment may be available. CMS does not permit co-surgeons or team surgery for this code.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
