Kaschin-Beck disease, unspecified ankle and foot

This code identifies Kaschin-Beck disease, a chronic, debilitating osteochondropathy characterized by degeneration of articular cartilage and growth plate disturbances. It specifically indicates involvement of an unspecified ankle and foot, without further detail regarding laterality.

Use this code when documentation confirms a diagnosis of Kaschin-Beck disease affecting the ankle and/or foot, but the specific side (right or left) is not documented or is unknown. This typically occurs in cases where the physician's notes or imaging reports clearly state Kaschin-Beck disease with ankle/foot involvement, but laterality is absent.

• Avoid using this code if laterality (right or left ankle/foot) is specified in the medical record; instead, select the more specific code.
• Ensure the documentation explicitly states Kaschin-Beck disease, not a general osteoarthropathy or other joint condition.
• This code should be sequenced as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity affecting treatment.
