Kaschin-Beck disease, left knee

This code signifies Kaschin-Beck disease affecting the left knee. Kaschin-Beck disease is a chronic, endemic osteochondropathy characterized by degenerative changes in articular cartilage and epiphyseal growth plates, leading to joint pain, stiffness, and deformities. It is primarily caused by environmental factors, particularly selenium deficiency.

Use this code when documentation explicitly states a diagnosis of Kaschin-Beck disease with involvement of the left knee. This diagnosis is typically supported by clinical examination findings of joint pain and swelling, imaging studies (X-rays, MRI) showing characteristic osteochondral changes in the left knee, and a history consistent with endemic exposure.

• Ensure the laterality (left knee) is clearly documented.
• Do not confuse with other forms of osteochondrosis or osteoarthritis; Kaschin-Beck disease has a distinct etiology and presentation.
• Consider co-reporting codes for associated symptoms or complications if documented, such as chronic pain or joint deformity.
