Partial physeal arrest, left distal tibia

This code signifies a growth plate abnormality in the left distal tibia where a portion of the physis has prematurely stopped growing, leading to potential limb length discrepancy or angular deformity. This condition can result from trauma, infection, or other growth disturbances affecting the epiphyseal plate.

Use this code when documentation clearly indicates a partial arrest of the growth plate in the specified anatomical location. Supporting documentation should include imaging reports (e.g., X-ray, MRI) confirming the physeal bar or bridge, and a physician's diagnosis of partial physeal arrest.

• Ensure laterality (left) and specific bone (distal tibia) are explicitly documented.
• Distinguish from complete physeal arrest, which would involve a different code.
• Look for associated conditions like limb length discrepancy (M21.622, M21.629) or angular deformity (M21.062, M21.162) that may also need to be coded.
