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

This code describes a specific type of incomplete fracture, a torus (or buckle) fracture, located at the distal end of the left humerus. The "nonunion" aspect indicates that the fracture fragments have failed to heal together after a typical healing period, and this encounter is for ongoing management of this complication.

Use this code when a patient presents for follow-up care, evaluation, or treatment of a previously diagnosed torus fracture of the lower left humerus that has not healed. This includes situations where surgical intervention for nonunion is being planned or performed, or conservative management for the nonunion is ongoing.

• Ensure documentation clearly states "nonunion" and specifies the left humerus.
• Verify this is a subsequent encounter for the fracture, not the initial treatment.
• Distinguish torus fractures from other types of humeral fractures.
