Nondisp comminuted fx shaft of humerus, left arm, init

This code signifies a fracture of the main part of the left upper arm bone (humerus) that has broken into multiple fragments, but the bone pieces remain in their normal anatomical alignment. This is an acute injury, and the skin over the fracture site is intact.

Use this code for a patient presenting with a newly diagnosed comminuted fracture of the shaft of the left humerus where the fracture fragments are not displaced. This applies to the initial treatment phase of a closed fracture, such as when a patient first presents to the emergency department or orthopedic clinic for this injury.

• Ensure documentation specifies "nondisplaced" and "comminuted" for the humeral shaft.
• Verify laterality (left arm) is clearly documented.
• The "A" suffix indicates an initial encounter for a closed fracture; subsequent encounters will require different seventh characters.
