Displ subtrochnt fx unsp femr, 7thR

This code describes a subtrochanteric fracture of the femur that has healed in an unsatisfactory position (malunion) and was initially an open fracture of type IIIA, IIIB, or IIIC. The fracture location is below the lesser trochanter but above the femoral condyles, and the specific femur (left or right) is not documented. This code is used for follow-up care after the initial treatment of the fracture.

This code is appropriate for subsequent encounters when a patient presents with complications related to a previously treated open subtrochanteric femoral fracture, specifically malunion. It would be used for patients undergoing evaluation or treatment for the malunion itself, such as planning for corrective osteotomy or managing ongoing pain and functional limitations.

• Ensure documentation clearly specifies "malunion" and the original open fracture type (IIIA, IIIB, or IIIC).
• Verify that the encounter is for follow-up care of the malunion, not the initial fracture treatment.
• If the laterality of the femur is known, a more specific code should be selected (e.g., S72.231R for right, S72.232R for left).
