Torus fx lower end of l humerus, subs for fx w malunion

This code signifies a specific type of incomplete fracture, known as a torus or buckle fracture, affecting the lower portion of the left humerus. The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously diagnosed fracture, and "malunion" specifies that the fracture has healed, but in an unsatisfactory or deformed position.

Apply this code when documenting ongoing treatment or evaluation of a patient whose left distal humerus torus fracture has healed improperly. This includes scenarios where the malunion is being monitored, or if interventions are being considered or performed to address the anatomical deformity resulting from the malunion.

• Confirm that the fracture is specifically a torus (buckle) type and located at the lower end of the left humerus.
• Ensure the encounter is for follow-up care of the fracture, not the initial treatment.
• Verify documentation explicitly states "malunion" to support the seventh character 'P'.
