Torus fx upper end of left ulna, subs for fx w nonunion

This code signifies a specific type of incomplete fracture, a torus or buckle fracture, affecting the upper portion of the left ulna. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone fragments have failed to heal together after a significant period.

This code is appropriate for encounters where a patient with a previously diagnosed torus fracture of the proximal left ulna is being treated for the ongoing failure of the fracture to unite. This would include follow-up appointments, imaging studies to assess nonunion, or discussions regarding potential interventions for the nonunion.

• Ensure documentation clearly specifies "torus fracture" and "nonunion" for the left ulna.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm laterality (left ulna) is explicitly stated in the medical record.
