Nondisp fx of less trochanter of l femr, 7thN

This code describes a previously treated, non-displaced fracture of the lesser trochanter on the left femur that has failed to heal properly (nonunion). The original injury was an open fracture, classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination.

Use this code for patients presenting for ongoing management or treatment of a nonunion of a lesser trochanter fracture of the left femur. This applies when the initial fracture was open and categorized as a severe type (IIIA, IIIB, or IIIC), and the fracture fragments are still in their anatomical position.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for treatment of this complication.
• Verify the original fracture was indeed an open fracture of type IIIA, IIIB, or IIIC, and that the lesser trochanter was involved.
• Confirm the fracture is nondisplaced; displaced fractures of the lesser trochanter have different codes.
