Q: The surgeon performs open reduction internal fixation (ORIF) of an unstable ankle fracture (e.g., CPT 27814). During the procedure, a syndesmotic screw is placed to stabilize the ankle mortise. Can 27829 (open treatment of distal tibiofibular joint disruption) be reported separately?
A: It depends. 27829 is NOT separately reportable when syndesmotic fixation is performed as part of routine ankle stabilization. 27829 may be reported separately(with modifier -59/XS) when: – distinct syndesmotic injury is documented, separate work beyond routine ankle stabilization and independent fixation is clearly described ORIF ankle fracture (27814) with syndesmotic screw, then only report 27814.

Q: Our surgeon performed a cavovarus reconstruction with a tendon transfer, calcaneal osteotomy, and lateral ankle ligament repair. How do we know if these can be billed separately?
A: The procedures may be billed separately if the documentation clearly links each procedure to distinct pathologic components of the deformity being corrected, such as muscle imbalance, bony malalignment, and ligamentous instability, rather than describing them as steps toward a single global correction.

Q: The operative note documents incision through skin, subcutaneous tissue, and deep fascia, followed by “treatment of the posterior tibial tendon.” How do we determine the correct CPT code from this documentation?
A: The documentation is insufficient; CPT coding is based on the specific work performed, not the depth of dissection or the structure identified. While the posterior tibial tendon is mentioned, the report does not specify what was actually done to the tendon, such as a tendon sheath incision, synovectomy, debridement, or repair. Without clear documentation of the procedural work performed, the case cannot be accurately coded.
