Bent bone of right ulna, subs for clos fx w malunion

This code signifies a right ulnar fracture that has healed in an anatomically incorrect position (malunion), resulting in a bent bone. It indicates that the initial fracture was closed and that the patient is now receiving care for the malunion, not the acute fracture.

This code is appropriate for follow-up encounters where a patient presents with a previously diagnosed closed right ulnar fracture that has healed with a noticeable deformity or angulation. This may include visits for evaluation of the malunion, planning for corrective surgery, or non-surgical management of symptoms related to the bent bone.

• Ensure documentation clearly specifies "right ulna" and "malunion" for accurate code selection.
• Verify that the encounter is for the sequela of the fracture (the malunion), not the initial fracture treatment.
• Always sequence this code after any codes for the underlying cause of the malunion or related symptoms if applicable.
