About 27707: Fibular corrective osteotomy
Reports a planned surgical cut and realignment of the fibula to correct a bone deformity or alignment problem involving the lower leg or ankle.
An orthopedic surgeon makes a controlled cut in the fibula and reshapes or repositions the bone according to the operative plan. The procedure may address fibular malalignment or a deformity affecting lower-leg or ankle alignment. It is generally performed in an operating room, such as a hospital or ambulatory surgery center. The operative report should identify the fibula as the bone treated and describe the deformity, the osteotomy performed, and the resulting correction.
Report this code when the procedure is confined to the fibula; a tibial osteotomy or osteotomies of both bones point to different codes. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27707 billing questions
How is this different from a tibial osteotomy?
This code is for an osteotomy of the fibula. Use the tibial osteotomy code when the tibia is the bone cut.
When is the code for osteotomy of both tibia and fibula a better fit?
Use the combined-bone code when the operative work includes osteotomies of both the tibia and fibula. This code describes work on the fibula alone.
What documentation supports reporting this code?
The operative report should identify the fibula, the alignment or deformity being treated, and the osteotomy and correction performed. It should also make clear whether the tibia was treated during the same session.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period. This applies to care related to the osteotomy.
How is bilateral surgery paid?
When the procedure is performed bilaterally and reported with modifier 50, Medicare pays it at 150%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment is restricted for this code. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.
