For the treatment of a malunion of an intertrochanteric fracture with proximal femoral osteotomy, what is the correct ICD-10-PCS code?

The correct code for the treatment of a malunion of an intertrochanteric fracture with proximal femoral osteotomy is derived from the ICD-10-PCS coding system, which categorizes procedures based on the type of procedure, the body part involved, and the approach used. In this case, we are looking for a code that represents an open surgical procedure for performing an osteotomy on the proximal femur.

The first three characters of the code identify the procedure being performed. In this instance, the core of the code indicates that an osteotomy is being carried out on the femur, specifically in a case where there is malunion associated with an intertrochanteric fracture.

The fourth character indicates the specific body part; the proximal femur code reflects that the procedure is focused on that area. The fifth character is used to describe the specific type of osteotomy being performed, and in this case, it signifies a correction of a malunion.

The last two characters typically describe the approach and whether any devices were used, with the Z in the code indicating that there is no specific device used, and a zero indicating that the procedure does not involve a change in the method of the treatment.

Thus, the correct identification of
