M90.821
ICD-10-CMThis code signifies a bone disorder or structural abnormality of the right upper arm that is secondary to, or a manifestation of, another underlying disease process. It indicates an osteopathic condition not primarily classified as a bone disease itself, but rather as a complication or feature of a systemic or localized illness affecting other body systems.
Apply this code when documentation specifies an osteopathy of the right upper arm that is a direct consequence of an underlying disease, such as metabolic disorders, infectious diseases, or neoplastic conditions. Supporting documentation should clearly link the bone involvement in the right upper arm to the primary disease.
