Kaschin-Beck disease, right ankle and foot

This code signifies a diagnosis of Kaschin-Beck disease affecting the right ankle and foot. Kaschin-Beck disease is a chronic, endemic osteochondropathy characterized by degenerative changes in cartilage and bone, leading to joint deformity and dysfunction. It primarily affects growing children and adolescents, often linked to environmental factors.

Use this code when documentation explicitly states a diagnosis of Kaschin-Beck disease localized to the right ankle and foot. This typically occurs in patients presenting with joint pain, swelling, and limited range of motion in the specified anatomical region, with imaging studies confirming characteristic osteochondral changes.

• Ensure documentation specifies "right" ankle and foot; laterality is crucial for accurate coding.
• Do not confuse with other forms of osteochondrosis or osteoarthritis; Kaschin-Beck disease is a distinct condition.
• Consider additional codes for associated symptoms or complications, such as pain (e.g., M25.571 for pain in right ankle and foot).
