Disp fx of less trochanter of unsp femr, 7thR

This code describes a fracture of the lesser trochanter, a bony prominence on the upper part of the femur, that is no longer in its anatomical alignment. This specific instance involves an open fracture (meaning the bone broke through the skin) classified as Type IIIA, IIIB, or IIIC, and is being treated during a subsequent encounter where the fracture has healed incorrectly (malunion).

This code is appropriate for documenting follow-up care for a patient who previously sustained a severe open lesser trochanteric fracture that has now healed with a deformity. It should be used when the malunion is the focus of the current encounter, such as for evaluation, planning for corrective surgery, or managing complications related to the malunion.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" for this specific fracture.
• Verify the original fracture was an open Type IIIA, IIIB, or IIIC to accurately assign this code.
• Do not use this code for initial treatment of the fracture or for nonunion; specific codes exist for those scenarios.
