Disp fx of base of neck of unspecified femur, sequela

This code signifies a long-term complication or late effect stemming from a displaced fracture located at the base of the femoral neck, where the specific side (left or right) of the femur is not documented. It indicates that the initial injury has healed, but the patient continues to experience residual problems directly attributable to that past fracture.

Apply this code when a patient presents for treatment of a condition that is a direct consequence of a previously healed, displaced fracture of the femoral neck base, and the medical record does not specify which femur was affected. Examples include chronic pain, nonunion, malunion, avascular necrosis, or degenerative arthritis occurring after the initial fracture has been treated.

• Ensure documentation clearly links the current condition to the past femoral neck fracture.
• This "S" seventh character indicates a sequela, meaning the acute phase of the fracture has passed.
• Do not use for initial or subsequent encounters for the acute fracture itself.
