Nondisp fx of sternal end r clavicle, subs for fx w malunion

This code signifies a fracture of the sternal end of the right clavicle that is not displaced, meaning the bone fragments are still in their normal anatomical position. The patient is in a subsequent phase of treatment, and the fracture has healed improperly, resulting in a malunion.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed nondisplaced fracture of the sternal end of the right clavicle, and imaging or clinical assessment confirms malunion. This could include visits for ongoing management of the malunion, assessment for surgical correction, or physical therapy related to the malunion.

• Ensure documentation clearly specifies "nondisplaced" and "right clavicle, sternal end."
• Verify the encounter is "subsequent" and explicitly states "malunion" as the complication.
• Do not use for initial fracture treatment or if the fracture is still healing normally.
