Torus fx lower end of unsp ulna, subs for fx w delay heal

This code signifies a buckle fracture, or torus fracture, affecting the lower portion of the ulna, where the bone cortex buckles but does not completely break. It indicates that the patient is in a phase of treatment where the fracture is not healing at the expected rate.

Apply this code when documenting follow-up care for a torus fracture of the distal ulna that is exhibiting delayed union. This would be used during subsequent visits after the initial treatment, when the physician notes that the healing process is slower than anticipated.

• Ensure documentation clearly states "delayed healing" for this specific fracture site.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
• Verify the fracture is indeed a torus fracture of the lower end of the ulna and not another type of fracture or location.
