Kaschin-Beck disease, unspecified knee

This code identifies Kaschin-Beck disease, a chronic osteochondropathy characterized by degenerative changes in cartilage and bone, specifically affecting an unspecified knee joint. It results from environmental factors, primarily nutritional deficiencies, leading to joint pain, stiffness, and deformity.

Use this code when the medical record documents a diagnosis of Kaschin-Beck disease and specifies involvement of a knee, but does not specify laterality (left or right). Documentation should clearly indicate the diagnosis and the affected joint, without further detail on which knee is involved.

• Avoid using this code if laterality of the knee is specified; instead, select the more specific code for left or right knee.
• Ensure the documentation explicitly states "Kaschin-Beck disease" and "knee involvement."
• Consider co-morbidities or complications related to the disease, such as osteoarthritis, and code them separately if documented.
