Pathological fracture, unsp shoulder, init for fx

This code signifies a fracture of an unspecified shoulder bone that occurred due to an underlying disease process, rather than trauma. The bone was weakened by a condition such as osteoporosis, a tumor, or an infection, leading to the fracture. This specific code is for the initial treatment of this type of fracture.

Apply this code when documentation clearly indicates a shoulder fracture resulting from a pathological condition, and the encounter represents the patient's first visit for this specific fracture. This includes situations where the patient presents with a new pathological fracture of the shoulder, regardless of the specific bone involved (e.g., humerus, scapula, clavicle) if not specified. Supporting documentation should detail the pathological nature of the fracture and the initial treatment phase.

• Ensure documentation specifies "pathological fracture" and not merely a "spontaneous" or "nontraumatic" fracture, as these terms are not synonymous.
• If the specific bone of the shoulder (e.g., humerus, clavicle, scapula) is documented, a more specific code from the M84.41- subcategory should be used.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, followed by codes for the underlying pathological condition.
