Nondisp intertroch fx l femr, 7thN

This code describes a left femur fracture located between the greater and lesser trochanters that is not displaced. It specifically indicates that the fracture was initially an open fracture of a severe type (IIIA, IIIB, or IIIC) and is now being treated for a nonunion, meaning the bone has failed to heal properly.

Use this code for follow-up encounters where a patient is receiving ongoing treatment for a previously diagnosed nondisplaced intertrochanteric fracture of the left femur. The key is that the original injury was a severe open fracture, and the current encounter addresses the complication of nonunion. This would apply to situations like surgical revisions, bone grafting, or prolonged immobilization for the nonunion.

• Always confirm the laterality (left femur) and displacement (nondisplaced) from the medical record.
• Ensure documentation clearly specifies the original fracture was an open fracture type IIIA, IIIB, or IIIC, and that the current encounter is for a nonunion.
• This "N" seventh character indicates a subsequent encounter for nonunion; do not use for initial treatment or routine follow-up of a healing fracture.
