Summary & Overview
CPT 27725: Tibial Nonunion or Malunion Repair with Tibiofibular Fusion
CPT code 27725 represents surgical repair of a tibial fracture that has failed to heal or has healed with poor alignment by fusing the tibia with the fibula. It captures a specific reconstructive orthopedic procedure used to treat tibial nonunion or malunion, conditions that can cause prolonged disability and require definitive operative management. Nationally, accurate coding for this procedure affects procedure tracking, quality measurement, and appropriate reimbursement for complex lower-extremity reconstructions.
Key payers referenced in the analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find clinical context on when this procedure is used, typical sites of service, and coding clarity to distinguish it from other tibial or fibular procedures. The publication provides benchmarks where available, notes on payer coverage patterns, and any pertinent policy updates that affect prior authorization and medical necessity review for complex orthopedic fusion procedures. Practical information on billing considerations and related service-line implications is summarized to support coding professionals, practice managers, and policy analysts in applying CPT code 27725 consistently across clinical settings.

Billing Code Overview
CPT code 27725 describes a surgical procedure in which the provider repairs a tibial fracture that has failed to heal or has healed with poor alignment by fusing it with the fibula. This operation is a reconstructive orthopedic procedure addressing nonunion or malunion of the tibia by performing a tibiofibular fusion to restore alignment and promote stability.
-
Service type: Orthopedic reconstructive surgery for tibial nonunion or malunion
-
Typical site of service: Inpatient hospital or ambulatory surgical center depending on clinical complexity and perioperative needs
Clinical & Coding Specifications
Clinical Context
A typical patient is a 35–65 year-old adult with a nonunion or malunion of the distal tibia after prior high-energy fracture or failed internal fixation. The patient presents with persistent pain, deformity, instability, or impaired ambulation months after the index injury. Imaging (plain radiographs +/- CT) demonstrates a tibial nonunion or malalignment with viable ipsilateral fibula suitable for fusion. The clinical workflow includes preoperative evaluation (history, physical, vascular/neurovascular assessment, optimization of medical comorbidities), informed consent discussing risks and expected outcomes of tibiofibular synostosis, preoperative imaging and templating, operative fixation with preparation of tibial and fibular surfaces and fixation to achieve fusion (CPT 27725), intraoperative fluoroscopy, possible bone grafting or revision hardware removal, postoperative immobilization and weight-bearing restrictions, serial radiographic follow-up to document fusion, and rehabilitation with progressive weight-bearing and physical therapy as indicated.

| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when documented work or complexity substantially exceeds usual and is supported by operative report for extensive dissection, revision hardware removal, large bone grafting, or prolonged time. |
