Ant disp fx of sternal end of unsp clavicle, init for opn fx

This diagnosis code signifies a break at the sternal (medial) end of the collarbone, where the fractured bone fragments have shifted forward. The specific side (left or right) of the clavicle is not documented, and the fracture is exposed to the external environment (open fracture).

This code is appropriate for initial treatment encounters involving an open, anteriorly displaced fracture of the medial clavicle when the laterality is not specified. This often occurs following significant trauma, such as a direct impact to the chest or shoulder.

• Ensure documentation clearly states "anterior displacement" and "open fracture" at the sternal end.
• If laterality (left or right) is specified, a more specific code should be used.
• This code is for the initial encounter; subsequent encounters will require different seventh characters.
