Disp fx of less trochanter of unsp femr, 7thN

This code signifies a displaced fracture of the lesser trochanter, located on the upper part of the femur, that has failed to heal after initial treatment. Specifically, it indicates a subsequent encounter for an open fracture classified as type IIIA, IIIB, or IIIC, which are severe open fractures with significant soft tissue damage. The nonunion aspect means the bone fragments have not united and healing has ceased.

Use this code for follow-up encounters when a patient presents with a previously diagnosed displaced lesser trochanter fracture that was an open fracture (Type IIIA, IIIB, or IIIC) and is now confirmed to have nonunion. This applies when the patient is receiving ongoing treatment for the nonunion, such as surgical intervention, bone grafting, or prolonged casting.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the fracture is of the lesser trochanter and not another part of the femur.
