Disp fx of less tuberosity of l humer, 7thK

This code describes a situation where the lesser tuberosity of the left humerus, a bony prominence on the upper arm bone, has fractured and the broken pieces are not aligned correctly. Furthermore, the fracture has failed to heal properly after an initial treatment, indicating a nonunion.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed displaced fracture of the left humeral lesser tuberosity that has not united. This includes visits for ongoing management, evaluation of nonunion, or planning for further intervention such as surgery to promote healing.

• Ensure documentation clearly specifies "displaced" and "nonunion" for the lesser tuberosity of the left humerus.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Always sequence this code with an external cause code if the cause of the fracture is known and relevant to the current encounter.
