What 27715 covers

An orthopedic surgeon reports this service when surgically lengthening or shortening both lower-leg bones—the tibia and fibula. A typical clinical reason is correction of a leg-length discrepancy involving the lower leg. The operative report should identify both bones treated and describe the planned length correction; the code is not for work limited to one bone or for fracture repair alone. These procedures are generally performed in a hospital or ambulatory surgery center.

This major surgery has a 90-day global period, which includes the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is 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

27705Tibial osteotomy
27705 describes tibial osteotomy work. Use 27715 when the documented procedure includes lengthening or shortening both the tibia and fibula.
27709Osteotomy
Both codes involve the tibia and fibula, but 27715 represents length correction of both bones. Select based on the operative service documented.
27713Tibial lengthening
27713 is the tibia-focused osteotomy service involving an intramedullary lengthening device; 27715 concerns lengthening or shortening both lower-leg bones.

27715 billing questions

How does this differ from 27709?

27715 is for lengthening or shortening both the tibia and fibula. Consider 27709 when the documented service is an osteotomy of both bones without the length-correction service described by 27715.

Can 27715 be reported when only the tibia is treated?

No. The service represented by 27715 involves both the tibia and fibula. For tibia-only osteotomy work, compare the operative details with 27705 or the applicable tibial lengthening code.

What documentation supports reporting 27715?

Document the indication for length correction, the tibia and fibula treated, and the operative work performed to achieve the planned lengthening or shortening.

How should bilateral procedures be reported?

CMS identifies this as a bilateral procedure; reporting with modifier 50 is paid at 150%. The operative record should support treatment of both sides.

Are postoperative visits included?

Related postoperative care for 90 days is included in the global period, along with the day-before preoperative visit.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery services may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
