Fx unsp shoulder girdle, part unsp, subs for fx w malunion

This code signifies a fracture of the shoulder girdle where the specific bone involved is not documented, and the encounter is for a malunion of that fracture. Malunion indicates the fracture has healed in an anatomically incorrect or deformed position. This is a subsequent encounter, meaning the initial treatment for the fracture has already occurred.

This code is appropriate when a patient presents for follow-up care of a previously treated shoulder girdle fracture that has healed improperly, and the exact bone (e.g., clavicle, scapula) is not specified in the documentation. It applies to situations where the focus of the encounter is on managing the complications of the malunion, such as pain, limited range of motion, or the need for corrective surgery.

• Ensure documentation clearly states "malunion" and that the encounter is not for initial treatment or routine follow-up of a healing fracture.
• Verify that the specific shoulder girdle bone is truly unspecified; if known, a more specific code should be used.
• Pair with an external cause code if the cause of the original fracture is relevant to the current encounter.
