Juvenile osteochondrosis of hip and pelvis

This code identifies a group of disorders affecting the growth plates of the hip and pelvis in children and adolescents, leading to avascular necrosis and subsequent deformity. It encompasses conditions like Legg-Calvé-Perthes disease, where the femoral head loses its blood supply. The condition results in bone death, collapse, and eventual re-ossification, often leading to long-term joint issues.

Apply this code when documentation specifies a diagnosis of juvenile osteochondrosis affecting the hip or pelvis. This includes diagnoses such as Legg-Calvé-Perthes disease, osteochondrosis of the acetabulum, or other specified osteochondroses of these anatomical sites in a pediatric patient. Supporting documentation should include imaging findings (X-ray, MRI) confirming avascular necrosis or growth plate abnormalities.

• Differentiate from adult osteonecrosis of the femoral head, which has different ICD-9-CM codes.
• Ensure the documentation clearly specifies "juvenile" or a pediatric age range for conditions like Legg-Calvé-Perthes.
• Do not use for general hip pain or unspecified osteochondrosis; specific anatomical site and juvenile onset are key.
