Fx r shoulder girdle, part unsp, subs for fx w nonunion

This code signifies a fracture of the right shoulder girdle where the specific bone involved is not documented, and the fracture has failed to heal properly. It indicates that the patient is receiving ongoing care for this nonunion, rather than initial treatment.

Use this code for a patient presenting for follow-up care, such as cast changes, physical therapy, or surgical intervention, for a previously diagnosed right shoulder girdle fracture that has not united. This applies when the physician explicitly documents "nonunion" and the specific bone (e.g., clavicle, scapula) is not specified.

• Ensure documentation clearly states "nonunion" and that this is a subsequent encounter.
• Verify that the laterality is specified as "right" and the specific shoulder girdle bone is not identified.
• If the specific bone is known (e.g., clavicle, scapula), a more precise code from the S42 series should be used.
