Kaschin-Beck disease, right knee

This code identifies Kaschin-Beck disease affecting the right 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 deformity. It primarily affects children and adolescents in specific geographical regions.

Use this code when documentation specifies Kaschin-Beck disease with involvement of the right knee joint. This diagnosis is typically supported by clinical examination findings consistent with osteoarthropathy, radiographic evidence of epiphyseal and metaphyseal changes, and a patient history from an endemic area.

• Ensure documentation clearly specifies "right knee" to support laterality.
• Do not confuse with other forms of osteochondropathy or osteoarthritis; Kaschin-Beck disease has distinct etiological and pathological features.
• Consider co-reporting codes for associated symptoms or complications, such as chronic pain (e.g., G89.29) or specific deformities, if documented.
