Nondisp seg fx shaft of r femur, subs for clos fx w nonunion

This code describes a situation where a patient has a fracture in the shaft of their right femur that is broken in multiple places (segmental) but the bone fragments are still aligned (nondisplaced). The key aspect is that the fracture is not healing as expected (nonunion) and this is a follow-up visit for the closed fracture.

Use this code when a patient presents for ongoing management of a previously diagnosed, nondisplaced segmental fracture of the right femoral shaft that has failed to unite. This typically applies to follow-up appointments where the physician is assessing the nonunion, planning further treatment, or monitoring the patient's condition.

• Ensure documentation clearly specifies "nonunion" and that the fracture is "segmental" and "nondisplaced."
• Verify this is a "subsequent encounter" for the fracture, not the initial treatment.
• Confirm the fracture is "closed" as indicated in the medical record.
