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

This code describes a buckle fracture, also known as a torus fracture, affecting the distal portion of the radius, where the bone cortex buckles rather than breaks completely. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "malunion" specifies that the fracture has healed in an unsatisfactory position.

Apply this code when a patient presents for ongoing treatment of a previously diagnosed torus fracture of the distal radius, and imaging or clinical assessment confirms that the fracture has healed with an unacceptable alignment. This would include scenarios such as physical therapy for a malunited fracture or surgical planning for corrective osteotomy.

• Ensure documentation clearly states "torus fracture" and "malunion" for the distal radius.
• Verify that the encounter is for follow-up care, not the initial treatment of the fracture.
• Do not use this code if the fracture is still in the acute healing phase or if it has healed with proper alignment.
