Nondisp subtrochnt fx unsp femr, subs for clos fx w nonunion

This code signifies a fracture located below the lesser trochanter of the femur that has not shifted from its original position. It is used when a patient is receiving follow-up care for this specific type of closed fracture, and there is evidence that the bone is failing to heal properly.

Apply this code when a patient with a previously diagnosed nondisplaced subtrochanteric femoral fracture presents for ongoing treatment, such as cast changes, physical therapy, or imaging, and the physician documents nonunion of the fracture. This would be appropriate for subsequent visits after the initial treatment of the fracture.

• Ensure documentation clearly states "nondisplaced" and "subtrochanteric" for accurate site specificity.
• Confirm the encounter is "subsequent" and that "nonunion" of a "closed" fracture is explicitly documented.
• Always review the medical record for laterality (left or right) if specified, as this code is for an unspecified femur.
