Nondisp commnt fx shaft of unsp femr, 7thR

This code describes a femur shaft fracture that is not displaced and has multiple fragments, indicating a comminuted pattern. It specifically applies to an open fracture (types IIIA, IIIB, or IIIC) that is currently in a subsequent encounter phase and has developed malunion, meaning the bone has healed in an incorrect anatomical position. The "unspecified femur" indicates the laterality is not documented.

Use this code when a patient presents for follow-up care of a previously treated open comminuted fracture of the femoral shaft, and imaging or clinical assessment confirms that the fracture has healed, but in an unsatisfactory alignment. This code is appropriate for ongoing management of the malunion, such as planning for corrective osteotomy or monitoring the functional impact of the deformity.

• Ensure documentation clearly specifies "subsequent encounter" and "malunion" for an open fracture.
• Verify the fracture is comminuted and nondisplaced; if displacement or a different fracture type is present, a different code is needed.
• Confirm the laterality of the femur is truly unspecified in the medical record before using this code.
