Displ seg fx shaft of l femr, 7thN

This code describes a complex fracture involving a segment of the shaft of the left femur that has shifted out of alignment. It specifically indicates that the fracture is an open fracture (meaning the bone broke through the skin) of a severe type (IIIA, IIIB, or IIIC) and has failed to heal properly after initial treatment.

This code is used during follow-up encounters for patients who have previously sustained a severe open segmental fracture of the left femoral shaft and are now experiencing nonunion. It applies when the patient is receiving ongoing care, such as further surgical intervention, casting, or physical therapy, for the unhealed fracture.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify the laterality (left femur) and the specific fracture type (segmental shaft fracture).
• This code is for subsequent encounters; use an initial encounter code for the initial treatment of the fracture.
