Nondisp subtrochnt fx unsp femr, 7thR

This code signifies a subtrochanteric fracture of the femur that is not displaced, meaning the bone fragments are still in their normal alignment. It specifically applies to a subsequent encounter where the initial fracture was an open fracture of type IIIA, IIIB, or IIIC, and has now healed incorrectly, resulting in a malunion. The location of the fracture is unspecified on the femur.

Use this code when documenting follow-up care for a patient whose previously sustained open subtrochanteric femoral fracture (types IIIA, IIIB, or IIIC) has healed in a misaligned position. This would typically be used for patients undergoing treatment for the malunion or for ongoing management of its complications.

• Ensure documentation clearly specifies "malunion" and the original open fracture type (IIIA, IIIB, or IIIC).
• Verify that the fracture is indeed "nondisplaced" at the time of this subsequent encounter.
• This code is for an "unspecified femur," so avoid using it if the laterality (left or right) is known.
