Nondisp fx of sternal end of unsp clavicle, init for opn fx

This code signifies a fracture at the sternal (medial) end of the clavicle that has not shifted from its normal anatomical position. It specifically indicates that the skin and soft tissue overlying the fracture site are compromised, exposing the bone to the external environment. This is the initial encounter for treatment of this injury.

Apply this code for patients presenting with a newly diagnosed, non-displaced open fracture of the medial clavicle. This is appropriate when the patient is receiving initial active treatment for the fracture, such as surgical intervention, casting, or external fixation.

• Confirm the fracture is explicitly documented as "nondisplaced" and "open."
• Ensure the encounter is the initial treatment for this specific injury.
• Later encounters for routine healing or follow-up would require a different encounter character (e.g., D for subsequent, S for sequela).
