Nondisp fx of less trochanter of unsp femr, 7thN

This code describes a fracture of the lesser trochanter of the femur that is not displaced, meaning the bone fragments remain in their normal alignment. This specific code is used when the patient is in a subsequent phase of care for an open fracture (where the skin was broken) of type IIIA, IIIB, or IIIC, and the fracture has failed to heal properly, resulting in a nonunion. The affected femur is not specified.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed open lesser trochanter fracture (types IIIA, IIIB, or IIIC) that has not united. This would include situations where the patient is undergoing further treatment, such as revision surgery, bone grafting, or prolonged immobilization, due to the nonunion. It signifies ongoing management of the fracture's healing complication.

• Ensure documentation clearly states "nondisplaced" and "nonunion" for an open fracture type IIIA, IIIB, or IIIC.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
• If the laterality (left or right femur) is documented, a more specific code should be used.
