What 27712 covers
An orthopedic surgeon cuts the tibia to correct a deformity, restores alignment, and stabilizes the correction with an intramedullary rod. The fibula may also be cut when needed to achieve the realignment. Typical situations include corrective surgery for a tibial malunion or angular deformity when rod fixation is part of the procedure. The service is performed in an operating room, generally in a hospital or ambulatory surgical setting.
Choose this code when the operative work includes tibial osteotomy, realignment, and intramedullary rod fixation; the presence of a rod alone is not enough. Document the deformity, osteotomy and alignment work, rod placement, and whether the fibula was also treated. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.

- Use 27709 for osteotomy of both the tibia and fibula when the operation does not meet 27712's rod-assisted realignment description.
- 27713Tibial lengthening
- Use 27713 when the tibial osteotomy is performed for lengthening with an intramedullary device, rather than the realignment service represented by 27712.
27712 billing questions
When should this be chosen over 27705?
Choose 27712 when the tibial osteotomy corrects alignment and is stabilized with an intramedullary rod. Code 27705 describes a tibial osteotomy without those specified features.
Is a fibular osteotomy separately reported when performed with this service?
The code includes fibular osteotomy when performed as part of the tibial realignment. Do not separately report 27707 for that same fibular work.
How is bilateral surgery reported?
Use modifier 50 for a bilateral procedure. CMS pays the bilateral service at 150%.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
What documentation supports assistant or co-surgeon billing?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, and CMS does not permit team surgery for this code.
