Path fx in oth disease, r shoulder, subs for fx w nonunion

This code signifies a fracture of the right shoulder that occurred due to an underlying disease process, rather than trauma. The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this unhealed fracture.

This code is appropriate for patients with a previously diagnosed pathological fracture of the right shoulder who are receiving ongoing treatment for the nonunion. Documentation should clearly state the pathological nature of the fracture, specify the right shoulder, and indicate that the fracture has not healed (nonunion) during a subsequent encounter.

• Ensure documentation specifies "pathological fracture" and the specific anatomical site (right shoulder).
• Confirm the encounter is for ongoing care of the nonunion, not the initial treatment or routine healing.
• Always code the underlying disease causing the pathological fracture first, followed by this code.
