What 29907 covers

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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

28725Subtalar fusion
Choose 29907 for arthroscopically performed subtalar fusion. Code 28725 represents subtalar arthrodesis without the arthroscopic approach.
29904Subtalar arthroscopy
29904 describes subtalar arthroscopy with removal of a loose body or foreign body; 29907 is for arthroscopic subtalar fusion.
29905Subtalar arthroscopy
29905 represents subtalar arthroscopy with excision. Use 29907 when the documented arthroscopic work includes subtalar arthrodesis.
29906Subtalar arthroscopy
29906 describes subtalar arthroscopy with debridement, not fusion. The documented operative objective distinguishes it from 29907.

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.
