Juvenile osteochondrosis of foot

This code represents a group of growth disturbances affecting the ossification centers (epiphyses) of the bones in the foot during childhood and adolescence. These conditions involve aseptic necrosis of bone, followed by regeneration, and are often associated with repetitive stress or trauma. Examples include Freiberg's disease (metatarsal head) or Kohler's disease (navicular bone).

Use this code for diagnoses of osteochondrosis specifically affecting any bone in the foot in a pediatric or adolescent patient. Documentation should clearly state the diagnosis of juvenile osteochondrosis and specify the affected foot bone, such as "Kohler's disease of the navicular" or "Freiberg's infraction of the second metatarsal head."

• Do not use this code for osteochondrosis affecting other anatomical sites; specific codes exist for other locations.
• Ensure the documentation specifies "juvenile" or indicates a pediatric/adolescent patient to support the "juvenile" aspect of the diagnosis.
• Distinguish from adult osteonecrosis or osteoarthritis, which have different underlying etiologies and corresponding codes.
