Greenstick fx shaft of humer, unsp arm, 7thK

This code signifies a greenstick fracture affecting the shaft of the humerus, where the specific arm (left or right) is not documented. Importantly, this code is used for follow-up care when the fracture has failed to heal properly, indicating a nonunion.

Apply this code when a patient presents for ongoing treatment of a previously diagnosed greenstick fracture of the humeral shaft, and the physician's documentation explicitly states or implies that the fracture has not united. This would typically be used after initial treatment has been rendered and the patient is returning for further management due to healing complications.

• Ensure documentation clearly specifies "nonunion" for the subsequent encounter.
• Verify that the fracture is indeed a greenstick type and located in the humeral shaft.
• Do not use this code for initial treatment or for subsequent encounters where the fracture is healing normally.
