Torus fx lower end of unsp radius, subs for fx w nonunion

This code signifies a torus, or buckle, fracture affecting the lower portion of the radius bone in the forearm, where the specific side (left or right) is not documented. Importantly, this diagnosis indicates that the fracture has failed to heal properly and the patient is presenting for follow-up care related to this nonunion.

This code is appropriate for encounters where a patient with a previously diagnosed torus fracture of the distal radius is being treated for a complication of nonunion. This would include visits for ongoing management, evaluation of non-healing, or preparation for further intervention due to the fracture not uniting.

• Ensure documentation clearly states "nonunion" in relation to the torus fracture.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Only use this code when the laterality of the radius is unspecified in the medical record.
