What 27758 covers
An orthopedic surgeon uses this service to expose and reduce a tibial shaft fracture and stabilize it with a plate, screws, or another non-intramedullary internal fixation construct. The code encompasses treatment of the tibial fracture whether or not a fibular fracture is also present. It is generally performed in an operating room; CMS 2024 claims show facility use for this code. The intramedullary nail approach is distinguished from this service and is reported with a different code.
Select the code from the operative report’s fracture location and fixation method, not simply from the fact that surgery occurred. Documentation should identify the tibial shaft fracture and describe open reduction and the fixation construct. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. With modifier 50, a bilateral procedure is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27758 billing questions
How does 27758 differ from 27759?
