Kaschin-Beck disease, unspecified hip

This code identifies Kaschin-Beck disease affecting an unspecified hip. Kaschin-Beck disease is a chronic, endemic osteochondropathy characterized by degenerative changes in articular cartilage and epiphyseal growth plates, leading to joint deformity and dwarfism, primarily affecting children and adolescents in specific geographic regions.

Apply this code when documentation confirms a diagnosis of Kaschin-Beck disease and the affected hip is not specified as right or left. This diagnosis is typically made based on clinical presentation, radiographic findings showing characteristic joint changes, and patient's geographic origin.

• Ensure documentation explicitly states Kaschin-Beck disease and does not specify laterality of the hip.
• If laterality (right or left hip) is documented, use the more specific codes M12.151 or M12.152.
• Consider co-occurring conditions such as nutritional deficiencies or environmental factors, and code them separately if documented.
