Juvenile osteochondrosis of metatarsus, unspecified foot

This code describes a developmental disorder affecting the growth plates (epiphyses) of the metatarsal bones in the foot of a juvenile patient. It involves a disruption of blood supply to the bone, leading to avascular necrosis and subsequent reossification, often resulting in pain and deformity. The "unspecified foot" indicates that the laterality (left or right) is not documented.

Use this code when documentation specifies juvenile osteochondrosis affecting the metatarsus without specifying which foot is involved. This diagnosis is typically made based on clinical presentation (e.g., foot pain, limping) and confirmed by imaging studies such as X-rays, which show characteristic changes in the metatarsal heads.

• Ensure the documentation clearly states "juvenile" or implies a pediatric patient.
• Avoid using this code if the laterality (left or right foot) is specified; instead, use the more specific codes M92.71 or M92.72.
• Consider co-reporting with codes for associated symptoms, such as foot pain (e.g., M79.67-).
