CPT Code for Right Ankle Syndesmosis ORIF
The CPT code for open reduction and internal fixation (ORIF) of a right ankle distal tibio-fibular syndesmosis is 27829 (Open treatment of distal tibiofibular joint [syndesmosis] disruption, includes internal fixation, when performed).
Key Coding Considerations
Primary Code
- CPT 27829 is the specific code for syndesmotic fixation when performed as the primary procedure or in isolation 1
Common Combination Scenarios
When syndesmotic fixation is performed in conjunction with ankle fracture repair, you may need to code both procedures:
- Lateral malleolus ORIF: CPT 27766,27769, or 27792
- Bimalleolar fracture ORIF: CPT 27814
- Trimalleolar fracture ORIF: CPT 27822 or 27823
Important Coding Pitfalls
Do not confuse syndesmotic fixation with standard malleolar fracture codes alone. The syndesmosis represents a distinct anatomic structure (the distal tibio-fibular joint) that requires separate coding when surgically addressed 1.
Laterality modifier: Add modifier -RT (right) to specify the right ankle, though this is typically captured in documentation rather than affecting the base CPT code.
Clinical Context
The frequency of syndesmotic fixation has increased significantly over the study period from 2007-2011, with syndesmotic fixation being performed more commonly across all ankle fracture patterns 1. This reflects growing recognition of syndesmotic injuries as independent contributors to poor outcomes when inadequately treated 3.
Hardware removal (if later required) would be coded separately as CPT 27829 with modifier -78 or as a distinct procedure, though the rate of hardware removal has been decreasing in recent years 1.
