    ICD-10-CM Code For Osteopathies In Diseases Classified Elsewhere: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group M90 includes osteopathies that arise secondary to diseases classified elsewhere, such as metabolic, endocrine, infectious, or neoplastic conditions affecting bone structure and growth. These ICD-10-CM diagnosis codes are used to document bone involvement related to systemic disease, capturing severity, anatomical site, and clinical complexity relevant to this group. Accurate coding within the ICD-10-CM M90 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM M90: Osteopathies In Diseases Classified Elsewhere Overview

    The diagnoses in this group represent bone disorders that occur as manifestations of systemic diseases classified in other chapters, affecting bone growth, density, structure, or healing. They target the skeletal system as affected secondary to conditions such as endocrine, metabolic, infectious, or neoplastic diseases. Accurate coding matters for correct clinical documentation and reimbursement because it links the bone pathology to the underlying systemic condition.

    When to Use

    Use a code from this group when documentation indicates a bone disorder is secondary to a specific disease classified elsewhere and the relationship between the primary disease and the osteopathy is clearly stated. Select codes that specify the anatomical site and any relevant complication or chronicity as documented in the medical record.

    Typical Clinical Scenarios

    • A middle-aged adult with long-standing diabetes presents to the emergency department with a nonhealing ulcer over the lateral ankle after minor trauma; radiographs show focal osteonecrosis of the distal tibial articular surface with subchondral collapse and surrounding osteoarthritic change. A diagnosis from this group is assigned to describe osteonecrosis occurring in bone as part of an underlying systemic disease process contributing to the nonhealing wound and joint collapse. Typical codes: M90.571, M90.572
    • An adolescent with a history of steroid therapy for leukemia complains of progressive hip pain and limited range of motion over months; MRI demonstrates avascular necrosis of the femoral head with early collapse and secondary degenerative changes. This chronic, progressive presentation related to an underlying medication exposure is coded using a code from this group to capture osteonecrosis in the setting of another disease or its treatment. Typical codes: M90.551, M90.552
    • An elderly patient admitted to the hospital for management of advanced rheumatoid arthritis is found on imaging to have multiple areas of osseous necrosis and deformity in the feet contributing to recurrent skin breakdown and infection; the osteopathic changes are documented as complications of the systemic inflammatory disease. A code from this group is used to report osteopathies that are manifestations or complications of the patient’s underlying rheumatologic condition and that affect management. Typical codes: M90.521, M90.522
