Fracture of unspecified part of neck of left femur, sequela

This code indicates a long-term complication or late effect resulting from a fracture of an unspecified part of the neck of the left femur. It signifies that the initial acute fracture has healed, but the patient continues to experience residual problems directly attributable to that past injury.

Apply this code when documenting a patient's current condition that is a sequela of a previously sustained fracture of the left femoral neck, where the specific part of the neck was not documented or is unknown. This is appropriate for conditions such as chronic pain, nonunion, malunion, avascular necrosis, or degenerative arthritis that developed as a direct consequence of the old fracture.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., M84.452A for malunion of left femur).
• Ensure documentation clearly links the current condition to the prior left femoral neck fracture.
• Do not use this code for the initial acute fracture or for subsequent encounters during the active healing phase.
