Path fracture in neoplastic disease, right ulna, init

This code signifies a fracture of the right ulna that occurred due to a pre-existing neoplastic (cancerous) condition, rather than from trauma. The bone has been weakened by the presence of a tumor, leading to a break with minimal or no force. This specific code indicates the initial treatment for this fracture.

Apply this code when documentation clearly states a pathological fracture of the right ulna and links it to an underlying neoplastic process. This is appropriate for the initial encounter where the fracture is being evaluated and/or treated. Supporting documentation would include imaging reports confirming the fracture and a medical history or pathology report indicating a primary or metastatic malignancy affecting the bone.

• Always sequence the underlying neoplasm code first, followed by this pathological fracture code.
• Ensure laterality (right ulna) is explicitly documented.
• Distinguish from traumatic fractures; the "pathological" nature must be clearly stated or implied by the clinical context.
