Displ intertroch fx unsp femr, 7thN

This code describes a situation where a patient has a previously treated intertrochanteric fracture of an unspecified femur that was open (meaning the bone broke through the skin or was exposed to the outside environment). The fracture has failed to heal properly, resulting in a nonunion, and the open wound was classified as a severe type IIIA, IIIB, or IIIC.

Use this code for follow-up encounters when a patient is being treated for a nonunion of a previously managed displaced intertrochanteric fracture of the femur. The original injury must have been an open fracture of a severe type (IIIA, IIIB, or IIIC) and the nonunion is the focus of the current treatment.

• Ensure documentation clearly specifies "nonunion" and the original fracture was an "open fracture type IIIA, IIIB, or IIIC."
• This code is for subsequent encounters, not the initial treatment of the fracture.
• Laterality (left/right) is unspecified in this particular code; if known, a more specific code should be sought.
