What 27705 covers

An orthopedic surgeon performs a planned cut in the tibia to change its alignment or shape. The operation may correct an angular or rotational deformity, such as tibial bowing or torsional malalignment. It is generally performed in an operating room, including a hospital or ambulatory surgical setting, with the cut planned to achieve the intended correction.

Report 27705 when the osteotomy involves the tibia alone; when the operation also osteotomizes the fibula, consider 27709. The operative report should identify the bone treated, the deformity or alignment problem, and the corrective work performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For same-session multiple procedures, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27705 billing questions

When should 27709 be reported instead?

Use 27709 when the operative procedure osteotomizes both the tibia and fibula. Report 27705 for the tibial osteotomy when the fibula is not also osteotomized.

How does 27705 differ from 27712 or 27713?

Those codes describe tibial osteotomy performed with specified realignment on an intramedullary rod or with a lengthening device. Select the code that matches the documented procedure and technique.

What documentation supports 27705?

Document the tibial deformity or alignment problem, the bone treated, and the osteotomy and correction performed. The report should make clear whether the fibula was also osteotomized.

How are other procedures in the same session paid?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%.
