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

This code describes a buckle fracture, or torus fracture, of the distal ulna where the bone cortex buckles but does not fully break. It specifically indicates that the patient is in the healing phase following the initial injury, and the healing process is progressing routinely without complications. The exact side of the injury (left or right) is not specified.

Apply this code when documenting follow-up care for a torus fracture of the lower ulna that is healing as expected. This would be appropriate for subsequent office visits, cast changes, or imaging reviews where routine healing is confirmed. It should be used after the initial encounter for the fracture.

• Ensure documentation specifies "unspecified ulna" if laterality is not explicitly stated.
• Confirm the encounter is for subsequent care and not the initial treatment.
• Verify that the healing is routine; use different codes for delayed or nonunion healing.
