Nondisp segmental fx shaft of humerus, left arm, init

This code signifies a break in the main part of the left upper arm bone (humerus) that occurs in at least two places along the shaft, but the bone fragments remain in their normal anatomical alignment. It indicates that the fracture is not displaced and is being treated for the first time.

Apply this code for a patient presenting with a newly diagnosed, non-displaced fracture of the humeral shaft on the left side, where imaging confirms a segmental pattern. This is appropriate for the initial medical encounter related to this specific injury.

• Ensure documentation clearly specifies "segmental" and "nondisplaced" for the humeral shaft fracture.
• Verify the laterality is explicitly stated as "left arm" in the medical record.
• Confirm this is the patient's first encounter for this specific fracture to use the "A" seventh character.
