Nondisp fx of base of neck of unspecified femur, sequela

This code signifies a past fracture of the base of the femoral neck that has since healed, but the patient is now experiencing a residual condition or complication directly related to that old injury. The fracture was not displaced at the time of the initial injury, and the specific side (left or right) of the femur is not documented.

Apply this code when a patient presents with a long-term consequence, such as chronic pain, stiffness, malunion, nonunion, or post-traumatic arthritis, stemming from a previously sustained and healed nondisplaced fracture of the base of the femoral neck. This code is appropriate for follow-up encounters where the focus is on managing the sequelae, not the acute fracture.

• Always ensure documentation clearly links the current condition to the past fracture.
• This code requires an additional code to specify the nature of the sequela (e.g., M25.55- for chronic pain, M84.45- for malunion).
• Do not use this code for an acute fracture or for a fracture that is still in the healing phase.
