Nondisp fx of lateral end l clavicle, subs for fx w malunion

This code signifies a previously treated fracture of the outer portion of the left collarbone that has healed improperly, resulting in a deformity. The bone fragments are still in their anatomical position relative to each other, but the healing process has led to an unsatisfactory alignment or union.

This code is used for follow-up encounters where a patient is being managed for a malunion of a nondisplaced fracture of the lateral end of the left clavicle. This includes situations where the malunion is being monitored, or when further intervention (e.g., surgical correction) is being planned or evaluated.

• Ensure documentation clearly states "malunion" and specifies the "lateral end" of the "left clavicle."
• Verify that the original fracture was "nondisplaced" and that this is a "subsequent encounter."
• Do not use for nonunion (failure to heal) or for initial treatment of the fracture.
