Displaced segmental fracture of shaft of unsp femur, sequela

This code signifies a long-term complication or late effect resulting from a past displaced segmental fracture of the shaft of an unspecified femur. It indicates that the original fracture involved multiple fragments within the shaft of the thigh bone, and these fragments were not in their anatomical alignment. The "sequela" aspect means the current encounter is for a condition directly attributable to the previous fracture, rather than the acute injury itself.

Use this code when documenting conditions such as chronic pain, malunion, nonunion, limb length discrepancy, or functional impairment that are directly linked to a previously sustained displaced segmental femoral shaft fracture. This code is appropriate for follow-up visits after the initial healing period, once the acute phase of the fracture has passed. It should be assigned when the patient is being treated for the residual effects of the old injury.

• Always assign this code as a secondary diagnosis, with the primary diagnosis describing the specific sequela (e.g., M84.459A for malunion of unspecified femur).
• Ensure documentation clearly links the current condition to the previous displaced segmental femoral shaft fracture.
• Do not use this code for initial treatment or active healing of the acute fracture; those encounters require acute fracture codes.
