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

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

This code is appropriate for encounters where a patient is being treated for complications arising from a left ulnar torus fracture that has healed improperly. This includes follow-up appointments for assessment of the malunion, planning for corrective procedures, or management of symptoms related to the malunion. It should be used after the initial treatment phase for the fracture.

• Ensure documentation clearly states "left ulna" and "torus fracture" or "buckle fracture."
• Verify the encounter is for follow-up care of a healed fracture with malunion, not initial treatment or active nonunion.
• Always check for laterality (left vs. right) and the specific bone involved.
