Juvenile osteochondrosis of hip and pelvis, unsp, right leg

This code represents an unspecified form of juvenile osteochondrosis affecting the hip and pelvis on the right side. It indicates a disorder of bone growth in children and adolescents where the bone tissue, particularly at the epiphysis, undergoes necrosis followed by regeneration, without specifying the exact type of osteochondrosis (e.g., Legg-Calvé-Perthes disease).

Use this code when documentation indicates juvenile osteochondrosis of the right hip and/or pelvis, but the specific type of osteochondrosis is not identified. This code is appropriate when the physician's diagnosis is generalized or awaiting further diagnostic clarification. Supporting documentation would include imaging reports and clinical notes confirming the presence of osteochondrosis in the specified anatomical area.

• Only use this code when the specific type of juvenile osteochondrosis (e.g., Legg-Calvé-Perthes) is not documented.
• Ensure the laterality (right) is clearly stated in the medical record.
• Avoid using this code if a more specific diagnosis, such as Legg-Calvé-Perthes disease (M91.1-), is provided.
