Juvenile osteochondrosis of proximal tibia, bilateral

This code signifies a developmental disorder affecting the growth plate (epiphysis) at the upper end of both shin bones in a juvenile patient. It involves a disturbance in the normal process of bone formation and cartilage growth, leading to pain, swelling, and potential deformity in both knees. This condition is often referred to as Blount's disease when affecting the proximal tibia.

Apply this code when documentation clearly indicates a diagnosis of osteochondrosis specifically impacting the proximal tibia on both sides in a pediatric or adolescent patient. Supporting documentation should include physician notes detailing bilateral involvement, diagnostic imaging findings (e.g., X-rays showing epiphyseal irregularities), and clinical symptoms consistent with this condition.

• Ensure documentation specifies "bilateral" involvement of the proximal tibia; otherwise, a unilateral code may be more appropriate.
• Differentiate from other osteochondroses affecting different anatomical sites or those with unspecified laterality.
• Consider sequencing with codes for associated symptoms like knee pain (M25.56-) or gait abnormalities (R26.0) if documented.
