Pathological fracture in neoplastic disease, l humerus, init

This code signifies a fracture of the left humerus that occurred due to an underlying neoplastic (cancerous) process, rather than trauma. The bone has been weakened by a tumor, leading to a break. This specific code is used for the initial treatment of this fracture.

Apply this code when documentation clearly indicates a pathological fracture of the left humerus caused by a neoplasm, and the patient is presenting for the initial treatment of this fracture. This includes surgical repair, casting, or other immediate interventions. Supporting documentation will include imaging reports confirming the fracture and pathology reports or clinical notes identifying the neoplastic etiology.

• Always sequence the underlying neoplasm code first, followed by this code.
• Ensure the laterality (left humerus) and encounter type (initial) are accurately reflected in the documentation.
• Distinguish from traumatic fractures (S42.2- series) or stress fractures, which have different etiologies.
