Complete physeal arrest, left proximal tibia

This code signifies the premature and complete cessation of growth plate activity in the proximal end of the left tibia. This condition results in a permanent growth disturbance, potentially leading to limb length discrepancy and angular deformities. It specifically indicates that the physis has fully fused, preventing further longitudinal bone growth.

Use this code when documentation clearly states complete physeal arrest affecting the proximal left tibia. This typically occurs following trauma, infection, or other growth plate injuries, or as a result of congenital conditions. Supporting documentation should include imaging reports (e.g., X-rays, MRI) confirming complete fusion of the growth plate.

• Ensure the documentation specifies "complete" arrest; partial arrest codes are distinct.
• Verify the laterality (left) and specific bone/location (proximal tibia) are accurately documented.
• Distinguish from epiphyseal separation (fracture) codes, which describe an acute injury rather than a growth arrest.
