Partial physeal arrest, left proximal tibia

This code signifies a condition where the growth plate (physis) in the upper part of the left shin bone has prematurely and incompletely stopped growing. This can lead to limb length discrepancies and angular deformities as the child continues to grow.

Apply this code when documentation confirms a partial closure or arrest of the proximal tibial physis on the left side. This diagnosis is typically made based on radiographic imaging (e.g., X-rays) showing a physeal bar or bridge, often in conjunction with clinical findings of growth disturbance.

• Ensure laterality (left) and anatomical site (proximal tibia) are clearly documented.
• Distinguish from complete physeal arrest, which would use a different subcategory.
• Consider co-reporting codes for any associated deformities or limb length discrepancies.
