Torus fx upper end of unsp ulna, subs for fx w malunion

This code signifies a torus, or buckle, fracture affecting the upper portion of the ulna bone, where the fracture has healed in an anatomically incorrect position (malunion). This type of fracture is typically stable and incomplete, often seen in pediatric patients due to bone elasticity. The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously diagnosed and treated fracture.

Use this code when documenting a patient visit for ongoing management or evaluation of a torus fracture of the proximal ulna that has resulted in malunion. This applies to scenarios such as physical therapy for range of motion limitations, imaging to assess the extent of malunion, or discussions regarding potential corrective procedures. It's appropriate for any encounter after the initial treatment phase.

• Ensure documentation clearly states "malunion" in relation to the torus fracture of the ulna.
• Verify the encounter type is "subsequent" and not initial or sequela.
• Confirm the fracture location is specifically the "upper end of the ulna" and not another part of the forearm.
