Displ seg fx shaft of unsp femr, subs for clos fx w nonunion

This code describes a situation where a patient has a fracture in the shaft of their femur, which is broken into multiple pieces (segmental) and the bone fragments are not properly aligned (displaced). This specific encounter is for ongoing treatment of a closed fracture that has failed to heal after the expected time frame (nonunion).

Use this code for follow-up encounters when a patient with a previously diagnosed displaced segmental femoral shaft fracture (closed type) is being treated for nonunion. This applies to situations where the physician is managing the non-healing fracture, such as during clinic visits for assessment, cast changes, or planning for further surgical intervention due to the nonunion.

• Ensure documentation clearly states "nonunion" and specifies a "subsequent encounter" for a closed fracture.
• Verify that the fracture is indeed segmental and displaced, and located in the shaft of the femur.
• Do not use this code for initial treatment of the fracture or for open fractures.
