Displ commnt fx shaft of humerus, right arm, init for opn fx

This code signifies a severe break in the main part of the right upper arm bone (humerus) that has shattered into multiple pieces and is out of alignment. The fracture has broken through the skin, exposing the bone to the external environment. This code is specifically for the initial treatment of such an injury.

This code is appropriate for documenting the initial encounter for a patient presenting with an open, comminuted fracture of the shaft of the right humerus. This includes emergency department visits, initial surgical repair, or the first physician visit for this specific injury. It is used when the patient is receiving active treatment for the fracture.

• Ensure documentation clearly specifies "right arm" and "open fracture" to support this code.
• Confirm the fracture is of the "shaft" and not the proximal or distal end of the humerus.
• The "B" seventh character indicates an initial encounter for an open fracture; subsequent encounters will require different seventh characters.
