Displaced fracture of base of neck of right femur, sequela

This code signifies a long-term complication or late effect stemming from a previously sustained fracture at the base of the neck of the right femur, where the bone fragments were not properly aligned. This could encompass conditions like malunion, nonunion, avascular necrosis, or chronic pain directly attributable to the original displaced fracture.

Utilize this code when documenting a patient presenting with a current condition that is a direct consequence of a past displaced fracture of the base of the neck of the right femur. This is appropriate for follow-up encounters addressing residual issues or complications that manifest after the initial healing phase of the fracture.

• Always sequence this "S" sequela code after the code describing the specific sequela (e.g., M84.451A for malunion of right femur).
• Ensure documentation clearly links the current condition to the previous displaced fracture of the right femoral neck.
• Do not use this code for initial treatment or active healing phases of the fracture; it is exclusively for late effects.
