Complete physeal arrest, left distal humerus

This code signifies the premature and complete cessation of growth at the epiphyseal plate (growth plate) in the distal portion of the left humerus. This condition results in a permanent shortening or deformity of the affected bone, as further longitudinal growth is no longer possible.

Apply this code when documentation explicitly states a complete physeal arrest affecting the left distal humerus, typically confirmed by imaging studies such as X-rays showing a fused growth plate. This diagnosis is often made in pediatric patients following trauma, infection, or other growth plate disturbances.

• Ensure documentation specifies "complete" arrest; partial arrest would require a different code.
• Verify the laterality (left) and specific bone segment (distal humerus) are clearly documented.
• Consider sequencing this code with an underlying cause if known and still active (e.g., prior fracture, infection).
