About 27709: Tibial and fibular corrective osteotomy
Surgical realignment by cutting both lower-leg bones is reported when correction requires osteotomy of the tibia and fibula during one operative session.
An osteotomy cuts and reshapes bone to change alignment. CPT 27709 is for operative correction involving both the tibia and fibula in the same lower leg, rather than an osteotomy limited to one bone. Orthopedic surgeons may use it to correct a structural deformity or malalignment when correcting both bones is part of the planned reconstruction. The service is generally performed in an operating room; fixation may be used as part of the surgeon’s technique.
Report the code when the operative record supports osteotomy of each bone. Documentation should identify the side, the reason for correction, and the work performed on the tibia and fibula. This major surgery code has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When other procedures are performed in the same session, the highest-valued procedure is paid in full and additional procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27709 billing questions
When should I report 27709 instead of 27705 or 27707?
Report 27709 when the operative service includes an osteotomy of both the tibia and fibula in the same lower leg. Use 27705 for tibial osteotomy alone or 27707 for fibular osteotomy alone.
Does the code include osteotomy of both bones on both legs?
The code describes work on the tibia and fibula of a lower leg. For bilateral procedures, CMS payment uses modifier 50 and is 150%; the record should support the work on each side.
What documentation supports reporting 27709?
Document the indication and side, and describe the osteotomy performed on each bone and the intended correction. The record should make clear why both bones required operative correction.
How does the 90-day global period affect follow-up visits?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period. Routine follow-up care related to the osteotomy falls within that period.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures in the same session are subject to the standard multiple procedure reduction, with payment at 50%.
Can an assistant or co-surgeon be paid for this operation?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
