Official Description

Repair of nonunion or malunion, tibia; with sliding graft

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 27722 refers to the surgical procedure for the repair of nonunion or malunion of the tibia, specifically utilizing a sliding graft technique. A nonunion occurs when the fracture fragments fail to heal together after an adequate period, while a malunion is characterized by improper alignment of the fracture fragments, leading to potential complications such as bone deformities, joint surface incongruities, soft tissue contractures, and nerve impingements. In this procedure, the surgeon exposes the original fracture site on the tibia to assess the condition of the nonunion or malunion and determine the appropriate repair method. Unlike CPT® Code 27720, which addresses similar issues without the use of a graft, this code involves the application of a sliding bone graft, typically indicated for malunion cases. The surgical approach includes cutting the tibia to allow for the repositioning of bone segments into their correct anatomical alignment, followed by the application of internal fixation devices to stabilize the fracture and ensure proper healing. This procedure is critical for restoring the structural integrity of the tibia and facilitating the healing process, ultimately improving the patient's functional outcomes.

1. Indications

The procedure coded under CPT® 27722 is indicated for the following conditions:

  • Nonunion of the Tibia - This condition arises when the fracture fragments do not unite after a sufficient healing period, necessitating surgical intervention to promote healing.
  • Malunion of the Tibia - This occurs when the fracture heals in an improper alignment, leading to potential complications such as deformities and functional impairments, which may require correction through surgical means.

2. Procedure

The procedure for CPT® 27722 involves several critical steps to ensure effective repair of the nonunion or malunion of the tibia:

  • Exposure of the Fracture Site - The surgical process begins with an incision to expose the original fracture site on the tibia. This allows the surgeon to evaluate the condition of the nonunion or malunion directly.
  • Assessment of the Fracture - Once exposed, the surgeon assesses the fracture to determine the necessary repair technique. This evaluation is crucial for deciding whether a sliding graft is appropriate.
  • Preparation of the Bone - The tibia is then cut using surgical instruments such as a drill, saw, or osteotome. This cutting is performed in a manner that allows the bone segments to be repositioned into their correct anatomical alignment.
  • Application of Internal Fixation - After realigning the bone segments, the surgeon secures them using internal fixation devices, which may include pins, screws, or plates. This stabilization is essential to maintain the alignment during the healing process.

3. Post-Procedure

Following the surgical procedure coded under CPT® 27722, the patient will typically require monitoring for signs of healing and potential complications. Post-operative care may include pain management, physical therapy to restore function, and regular follow-up appointments to assess the stability and alignment of the tibia. The expected recovery time can vary based on the individual patient's condition and adherence to rehabilitation protocols. It is essential for the surgical site to be kept clean and for the patient to follow any specific instructions provided by the healthcare team to ensure optimal healing.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
