Nondisp commnt fx shaft of l femr, 7thN

This code describes a comminuted fracture of the shaft of the left femur that is not displaced, meaning the bone fragments are still in their anatomical alignment. It specifically indicates a subsequent encounter for an open fracture of types IIIA, IIIB, or IIIC, where the fracture has failed to heal properly (nonunion).

Use this code for follow-up care of a patient with a previously diagnosed nondisplaced comminuted left femoral shaft fracture that was initially an open fracture (types IIIA, IIIB, or IIIC) and is now complicated by nonunion. This applies when the patient is receiving ongoing treatment for the nonunion, such as surgical intervention, bone grafting, or prolonged immobilization.

• Always confirm the laterality (left femur) and the specific fracture type (nondisplaced comminuted shaft).
• Ensure documentation clearly states "subsequent encounter" and "nonunion" for an open fracture type IIIA, IIIB, or IIIC.
• Do not use this code for initial treatment or for malunion; a different code would be appropriate in those scenarios.
