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

This code signifies a buckle fracture, or torus fracture, affecting the lower portion of the ulna, where the bone cortex buckles without a complete break. This specific code is used when the fracture has failed to heal properly (nonunion) and the patient is receiving follow-up care for this complication.

Apply this code for patients presenting for ongoing treatment of a torus fracture of the distal ulna that has been diagnosed with nonunion. This includes scenarios such as follow-up appointments for casting changes, physical therapy, or surgical planning related to the nonunion. It indicates that the initial treatment has not resulted in successful bone healing.

• Ensure documentation clearly states "nonunion" and specifies the lower end of the ulna.
• This code is for subsequent encounters, not the initial treatment of the fracture.
• Always check for laterality if specified in the medical record, as "unspecified" is used here.
