Oth fx shaft of r femur, subs for opn fx type I/2 w malunion

This code signifies a healed or healing fracture of the shaft of the right femur that was initially an open fracture (Type I or II) and has now resulted in malunion. Malunion indicates that the bone has healed in an incorrect anatomical position, potentially leading to functional impairment or deformity.

This code is appropriate for follow-up encounters where a patient is being treated for complications arising from a malunited open fracture of the right femoral shaft. It should be used when documentation clearly indicates that the initial injury was an open fracture of either Type I or II, and the subsequent healing has resulted in malunion.

• Ensure documentation specifies the initial open fracture type (I or II) for accurate coding.
• Verify that the encounter is for a subsequent visit related to the malunion, not the initial treatment.
• Confirm the fracture location is specifically the shaft of the right femur.
