170.4
ICD-9-CMThis code identifies a primary cancerous tumor originating in the bones of the shoulder blade (scapula) or the long bones of the upper arm (humerus, radius, ulna). It signifies a malignant growth within the osseous tissue of these specific upper limb structures.
Apply this code when documentation confirms a primary malignant neoplasm of the scapula, humerus, radius, or ulna. This typically follows a biopsy and pathological confirmation of malignancy. Ensure the medical record clearly specifies the primary nature and exact anatomical site within the upper limb bones.
