Juvenile osteochondrosis of humerus, left arm

This diagnosis code signifies a developmental disorder affecting the growth plate (epiphysis) of the humerus in a juvenile patient, specifically in the left arm. It involves a disturbance in the ossification process, leading to avascular necrosis and subsequent fragmentation and possible re-ossification of the bone. This condition is often referred to as Panner's disease when affecting the capitellum of the humerus.

Apply this code when documentation clearly indicates juvenile osteochondrosis affecting the humerus of the left arm. This typically presents in children or adolescents with elbow pain, stiffness, and limited range of motion. Supporting documentation should include imaging findings (e.g., X-rays, MRI) confirming osteochondral changes in the left humeral epiphysis.

• Ensure the laterality (left arm) is explicitly documented to support this specific code.
• Differentiate from other osteochondroses affecting different joints or bones.
• Do not confuse with adult osteochondrosis or traumatic injuries to the humerus.
