Fx unsp part of unsp clavicle, subs for fx w nonunion

This code signifies a fracture of the collarbone where the specific location on the clavicle is not documented, and it's also unknown whether it's the left or right side. Crucially, this code indicates that the fracture has failed to heal properly and the patient is receiving ongoing care for this nonunion.

This code is appropriate for follow-up encounters when a patient presents with a previously diagnosed clavicle fracture that has not united, and the documentation lacks specificity regarding the fracture's exact site or laterality. It's used for subsequent care related to the nonunion, such as evaluation for surgical intervention or continued conservative management.

• Ensure documentation clearly states "nonunion" and that the encounter is for ongoing care of the fracture.
• Only use this code when the specific part of the clavicle and laterality are truly unspecified in the medical record.
• Pair with an external cause code if applicable, especially for initial injury.
