Disp fx of base of nk of r femr, subs for clos fx w nonunion

This code signifies a fracture located at the base of the neck of the right femur that has shifted out of its normal alignment. The fracture is being treated non-surgically (closed treatment), and the bone fragments are failing to heal together properly, indicating a nonunion.

Apply this code for follow-up encounters where a patient with a previously diagnosed and treated displaced right femoral neck fracture (base) is experiencing nonunion, and the fracture is being managed without open reduction. This is appropriate when the patient is receiving ongoing care for the nonunion of a closed fracture.

• Ensure documentation clearly states "displaced" and "base of neck" for the right femur.
• Confirm the encounter is for a "subsequent" visit and the fracture is being treated as "closed" with evidence of "nonunion."
• Do not use this code for initial encounters, open fractures, or if the nonunion is not explicitly documented.
