Disp fx of less trochanter of unsp femr, 7thQ

This code describes a situation where a patient has a displaced fracture of the lesser trochanter of an unstated femur, and this is a follow-up encounter for a previously open fracture (Type I or II) that has healed incorrectly (malunion). The lesser trochanter is a bony prominence on the upper part of the femur, serving as an attachment point for the iliopsoas muscle. "Displaced" indicates the bone fragments are not in their normal anatomical alignment.

This code is appropriate for subsequent encounters when a patient is being treated for complications arising from a malunited, previously open lesser trochanter fracture. This could include follow-up appointments for ongoing management of the malunion, assessment of functional limitations, or planning for corrective procedures. It specifically applies when the laterality of the femur (left or right) is not documented.

• Ensure documentation clearly states "subsequent encounter" and specifies a malunion of a previously open fracture.
• Verify that the fracture is indeed of the lesser trochanter and not another part of the femur.
• Only use this code when the laterality of the femur is truly unspecified in the medical record. If laterality is documented, a more specific code should be chosen.
