Displaced transcondy fx r humerus, subs for fx w malunion

This code signifies a right humerus fracture that extends across the condyles, where the bone fragments have healed in an unsatisfactory position (malunion). The patient is currently receiving follow-up care for this previously treated fracture, which has resulted in an anatomical deformity.

Apply this code when a patient presents for ongoing management, evaluation, or treatment of a right transcondylar humeral fracture that has healed with malunion. This includes scenarios such as physical therapy for range of motion limitations, surgical planning for corrective osteotomy, or imaging to assess the extent of the malunion.

• Ensure documentation clearly states "malunion" and specifies the "right humerus" and "transcondylar" location.
• Confirm this is a "subsequent encounter" for the fracture, indicating ongoing care after initial treatment.
• Verify laterality (right) is explicitly documented; do not assume.
