Fx unsp prt of nk of l femr, 7thR

This code describes a malunion of an open fracture involving an unspecified part of the neck of the left femur, specifically when the initial open fracture was classified as Type IIIA, IIIB, or IIIC. Malunion indicates that the fracture has healed but in an unsatisfactory or deformed position, which may lead to functional impairment.

Use this code for a patient presenting for follow-up care or treatment of a previously diagnosed open fracture of the left femoral neck (Type IIIA, IIIB, or IIIC) that has healed in a misaligned or deformed manner. This code is appropriate when the malunion is the primary reason for the current encounter.

• Ensure documentation clearly specifies "malunion" and the "left" side.
• Verify the original open fracture type (IIIA, IIIB, or IIIC) is documented.
• This code is for subsequent encounters, not the initial treatment of the fracture.
