Juvenile osteochondrosis of head of femur, left leg

This code represents Legg-Calve-Perthes disease affecting the left femoral head. This condition is an idiopathic avascular necrosis of the capital femoral epiphysis, leading to collapse and deformity of the femoral head in children. It primarily affects the hip joint.

Assign this code for a confirmed diagnosis of Legg-Calve-Perthes disease specifically impacting the left hip. Documentation should clearly state the diagnosis and laterality, often supported by radiographic findings (e.g., MRI, X-ray) showing avascular necrosis of the left femoral head.

• Ensure laterality is precisely documented; do not default to unspecified if left or right is known.
• Distinguish from other forms of osteochondrosis or avascular necrosis affecting different anatomical sites.
• Code any associated complications, such as osteoarthritis or deformity, separately if present.
