Nondisp fx of lateral condyle of unsp tibia, 7thN

This code signifies a previously treated fracture of the outer bony prominence of the shin bone, near the knee, that was initially an open fracture with significant soft tissue damage (Type IIIA, IIIB, or IIIC). The fracture itself remains in its anatomical position, but the bone has failed to heal after the initial treatment.

Apply this code for follow-up encounters where a patient with a history of a severe open lateral tibial condyle fracture presents with documented nonunion. This is used when the fracture fragments are still aligned but healing has ceased.

• Ensure documentation explicitly states "nonunion" and specifies the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is described as "nondisplaced" in the current encounter.
• This code is for subsequent encounters, not the initial treatment of the fracture.
