Pathological fracture, unsp humerus, init for fx

This code signifies a bone fracture in the humerus (upper arm bone) that occurred due to a pre-existing disease process, rather than trauma. The specific humerus (left or right) is not documented, and this is the initial visit for treatment of the fracture.

Use this code when documentation clearly states a pathological fracture of the humerus without specifying laterality, and the patient is receiving active treatment for the fracture. This typically applies to fractures resulting from conditions like osteoporosis, metastatic cancer, or bone cysts.

• Always seek documentation for the underlying disease causing the pathological fracture and code it first.
• Confirm the encounter type (initial, subsequent, sequela) to ensure correct 7th character assignment.
• Avoid using this code if laterality (left or right humerus) is specified; choose a more specific code.
