Kaschin-Beck disease, unspecified shoulder

This diagnosis code signifies Kaschin-Beck disease affecting an unspecified shoulder. Kaschin-Beck disease is a chronic, endemic osteoarthropathy characterized by degeneration and necrosis of cartilage and bone, primarily affecting the epiphyseal and articular cartilage of growing individuals. It leads to joint deformities, pain, and limited mobility.

Use this code when documentation specifies Kaschin-Beck disease impacting the shoulder, but the laterality (right or left) is not explicitly stated. This diagnosis is typically made based on clinical presentation, radiographic findings (e.g., epiphyseal necrosis, joint space narrowing), and patient history from endemic regions.

• Ensure the medical record clearly states Kaschin-Beck disease as the diagnosis.
• If laterality is documented (right or left shoulder), select the more specific code (M12.111 or M12.112).
• Consider co-occurring conditions like osteoarthritis (M15.-) or other osteochondropathies (M91-M93) if also documented.
