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

This code signifies a torus, or buckle, fracture affecting the lower portion of the left ulna, which is currently undergoing treatment for a malunion. A torus fracture is an incomplete fracture where the bone cortex buckles but does not completely break. Malunion indicates that the fracture has healed, but in an unsatisfactory or deformed position.

Use this code when documenting a patient presenting for follow-up care, rehabilitation, or further intervention related to a previously sustained torus fracture of the distal left ulna that has healed improperly. This would include scenarios where surgical correction of the malunion is being planned or has been performed, or conservative management of the malunion is ongoing.

• Ensure documentation clearly specifies "left" ulna and "lower end" or "distal" ulna.
• The "P" seventh character indicates a subsequent encounter for a fracture with malunion, so confirm the patient is beyond the initial healing phase.
• Always review the medical record for any associated complications or additional injuries that may require separate coding.
