Disp fx of less trochanter of r femr, 7thN

This code describes a situation where the lesser trochanter of the right femur has fractured and the bone fragments are no longer in their normal alignment. This specific encounter is for an open fracture (where the bone broke through the skin) of a severe type (IIIA, IIIB, or IIIC), and the fracture is failing to heal properly (nonunion).

Use this code when a patient presents for follow-up care of a previously diagnosed displaced open fracture of the right femoral lesser trochanter, and the physician documents that the fracture is not healing as expected. This applies to situations involving surgical intervention, wound care, or other management related to the nonunion of a severe open fracture.

• Ensure documentation clearly specifies "displaced" and "nonunion" for the lesser trochanter fracture.
• Verify the open fracture type (IIIA, IIIB, or IIIC) is explicitly stated or clearly inferable from the clinical notes.
• This code is for a subsequent encounter, so an initial encounter code would have been used previously.
