Juvenile osteochondrosis of patella, right knee

This code signifies a developmental disorder affecting the growth plate of the right patella (kneecap) in children and adolescents. It involves a disturbance in the normal process of bone formation, leading to fragmentation or necrosis of the patellar ossification center. This condition is often associated with repetitive stress or trauma to the knee.

Assign this code for a documented diagnosis of juvenile osteochondrosis specifically affecting the right patella. This typically presents with anterior knee pain, swelling, and tenderness over the kneecap in a pediatric or adolescent patient. Supporting documentation should include physician notes detailing the location and nature of the osteochondrosis, often confirmed by imaging studies such as X-rays or MRI.

• Ensure laterality is clearly documented as "right" to support this specific code.
• Differentiate from other forms of osteochondrosis affecting different bones or joints.
• Do not confuse with adult osteochondritis dissecans, which has different coding.
