Oth nondisp fx of upper end l humer, subs for fx w nonunion

This code indicates a fracture of the upper part of the left humerus that is not displaced, meaning the bone fragments are still in their normal alignment. The "subsequent encounter" aspect signifies that the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone has failed to heal completely after a reasonable period.

Use this code when documenting ongoing treatment for a patient whose left humerus fracture, initially nondisplaced in the upper end, has not healed as expected. This applies to situations where the physician is managing the nonunion, such as considering surgical intervention, bone grafting, or continued conservative management for the unhealed fracture.

• Ensure documentation clearly states "nonunion" and specifies the "left" side and "upper end" of the humerus.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use for displaced fractures or fractures of other parts of the humerus.
