Disp fx of lesser tuberosity of unsp humerus, init

This code signifies a broken bone in the upper arm, specifically a displacement of the lesser tuberosity, a small bony prominence on the humerus. The fracture is not open to the skin and is being treated for the first time.

Apply this code when documentation confirms a displaced fracture of the lesser tuberosity of the humerus, without specifying left or right, and the patient is presenting for initial treatment of the injury. This is appropriate for emergency department visits, initial orthopedic consultations, or hospital admissions for the acute injury.

• Ensure the documentation explicitly states "displaced" and "lesser tuberosity."
• Verify that the encounter is for the initial treatment of the fracture, indicated by the "A" seventh character.
• If laterality (left or right) is specified, a more specific code should be used.
