CPT Code for Left Distal Fibula Fracture with ORIF and Syndesmosis
The appropriate CPT code for open reduction and internal fixation of a distal fibular fracture is 27792, and syndesmotic fixation should be separately coded with 27829.
Primary Coding Structure
The procedure you're describing involves two distinct components that require separate coding:
- 27792: Open treatment of distal fibular fracture (lateral malleolus), includes internal fixation, when performed
- 27829: Open treatment of distal tibiofibular joint (syndesmosis) disruption, includes internal fixation, when performed
Key Coding Considerations
Both codes should be reported together when you perform ORIF of the fibula AND address the syndesmotic injury operatively. The syndesmosis repair is not bundled into the fibular fixation code and represents additional work that warrants separate reimbursement.
Important Coding Pitfalls to Avoid
- Do not use 27792 alone if you performed syndesmotic fixation—this underrepresents the work performed
- Modifier considerations: Depending on payer requirements, you may need to append modifier -51 (multiple procedures) to the secondary code, though many payers process this automatically
- Documentation requirements: Clearly document both the fibular fracture fixation AND the separate syndesmotic disruption/repair in your operative note to support both codes
Clinical Context from Evidence
Recent cost analysis data 1 confirms that 27792 is the standard CPT code used for isolated distal fibula fracture fixation across multiple surgical settings. The study evaluated 394 patients undergoing this procedure, validating this as the appropriate primary code for fibular ORIF.
Laterality and Specificity
While you specified "left" distal fibula, CPT codes themselves are not laterality-specific. However:
- Use modifier -LT to indicate left side for tracking and billing purposes
- Ensure your documentation clearly states "left distal fibula" throughout
Final Coding Recommendation
Report: 27792-LT and 27829-LT for your described procedure of left distal fibular ORIF with syndesmotic fixation.
