Unsp fx upper end of l humerus, subs for fx w delay heal

This code signifies a fracture of the upper portion of the left humerus where the specific type of fracture (e.g., surgical neck, anatomical neck) is not documented. The patient is in a subsequent phase of care, and the fracture is experiencing delayed healing, meaning it is taking longer than expected to unite.

Apply this code when a patient presents for follow-up care of an upper left humeral fracture that is not specified further, and the physician explicitly documents delayed healing. This is appropriate for ongoing management of the fracture after initial treatment, but before complete union.

• Ensure documentation clearly states "delayed healing" for the subsequent encounter.
• Verify the laterality is specifically "left" and the fracture location is the "upper end" of the humerus.
• Do not use this code for initial encounters or for fractures that are healing normally or experiencing nonunion.
