Displ transverse fx shaft of l femr, 7thR

This code describes a situation where a patient has a transverse fracture of the shaft of their left femur that was initially an open fracture (Type IIIA, IIIB, or IIIC), and has subsequently healed incorrectly, resulting in a malunion. This indicates a complication of healing where the bone fragments have united in a deformed position.

Use this code when documenting follow-up care for a patient whose previously treated open transverse left femoral shaft fracture (Type IIIA, IIIB, or IIIC) has resulted in malunion. This would typically be used during clinic visits or hospital admissions addressing the consequences or treatment of the malunion.

• Ensure documentation clearly specifies "malunion" and not just nonunion or delayed union.
• Verify the original fracture was an open fracture type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters, not the initial treatment of the fracture.
