Other juvenile osteochondrosis of hip and pelvis, right leg

This code signifies a non-specific osteochondrosis affecting the right hip and/or pelvis in a juvenile patient, not otherwise classified or specified as Legg-Calvé-Perthes disease or slipped capital femoral epiphysis. It involves a disturbance of bone growth at the epiphysis or apophysis, leading to avascular necrosis or fragmentation.

Apply this code when documentation indicates a juvenile osteochondrosis of the right hip or pelvis that doesn't fit more specific diagnoses like Legg-Calvé-Perthes disease. This is appropriate for conditions such as Ischiopubic osteochondrosis (Van Neck's disease) or other unspecified osteochondroses affecting the right side of the hip/pelvic region in a pediatric patient.

• Ensure the medical record clearly specifies "right" side involvement; otherwise, an unspecified side code may be more appropriate.
• Differentiate from Legg-Calvé-Perthes disease (M91.1-) and Slipped Capital Femoral Epiphysis (M91.2-) which have their own specific codes.
• Look for documentation of imaging findings (X-ray, MRI) confirming osteochondrosis and the specific anatomical location.
