Torus fx upper end of right ulna, subs for fx w nonunion

This code signifies a buckle fracture, or torus fracture, affecting the upper portion of the right ulna. It specifically indicates that the patient is presenting for follow-up care of this fracture, and the fracture has failed to heal properly (nonunion).

This code is appropriate for subsequent encounters when a patient is receiving ongoing treatment for a torus fracture of the proximal right ulna that has not united. This includes situations where further interventions, such as bone grafting or revision surgery, are being considered or performed due to the nonunion. It would also be used for follow-up visits to monitor the nonunion.

• Ensure documentation clearly specifies "torus fracture" and "nonunion" for the right ulna.
• Verify the encounter is "subsequent" and not an initial treatment for the fracture.
• Always sequence this code with an external cause code (20th character) if applicable, to describe the cause of the injury.
