Torus fx lower end of right ulna, subs for fx w malunion

This code signifies a buckle fracture, or torus fracture, affecting the distal portion of the right ulna. It specifically indicates that the patient is in a subsequent phase of care for this fracture, and there is evidence of malunion, meaning the bone has healed in an unsatisfactory position.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed torus fracture of the right distal ulna that has healed incorrectly. It should be used when documentation confirms the fracture has united but with an unacceptable alignment, requiring ongoing management or evaluation.

• Ensure documentation clearly specifies "subsequent encounter" and "malunion" for the right ulna.
• Verify the fracture type is explicitly documented as a "torus" or "buckle" fracture.
• Do not use this code for initial encounters or for nonunion; specific codes exist for those scenarios.
