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

This diagnosis code signifies a previously treated fracture of the outer portion of the left collarbone that has healed incorrectly, resulting in a deformity. The patient is presenting for ongoing care related to this malunion, rather than the initial injury or routine follow-up for a well-healing fracture.

This code is appropriate when a patient is seen for management of a left clavicle fracture that has healed in an anatomically incorrect position, causing functional impairment or cosmetic concerns. It should be used for encounters where the focus is on addressing the consequences of the malunion, such as pain, limited range of motion, or planning for corrective surgery.

• Ensure documentation clearly states "malunion" and specifies the left clavicle and its lateral end.
• Verify that this is not an initial encounter or a routine follow-up for a healing fracture without complications.
• Always sequence with any associated external cause codes, if applicable, to describe the mechanism of injury.
