Oth fracture of right lower leg, subs for clos fx w nonunion

This code signifies a fracture in the lower part of the right leg, excluding the ankle or foot, that has not healed properly (nonunion) and is being treated in a subsequent encounter. The fracture was initially closed, meaning the skin was not broken at the time of injury.

Use this code when a patient presents for follow-up care, such as cast changes, physical therapy, or surgical planning, for a previously diagnosed closed fracture of the right tibia or fibula (excluding ankle/foot) that has failed to unite. This applies when the nonunion is documented by the physician.

• Ensure documentation clearly states "nonunion" and specifies the "right lower leg" and "closed fracture."
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use for fractures of the ankle (malleolus) or foot; specific codes exist for those locations.
