Partial physeal arrest, left distal humerus

This code signifies an incomplete cessation of growth in the growth plate (physis) located at the lower end of the left upper arm bone (humerus). This condition can lead to limb length discrepancies or angular deformities if not addressed.

Apply this code when documentation confirms a partial physeal arrest affecting the distal humerus on the left side. This diagnosis is typically made based on imaging studies (e.g., X-rays) showing a bridging bar across the physis, often in conjunction with clinical signs of growth disturbance.

• Ensure the documentation specifies "partial" arrest and the exact location (distal humerus) and laterality (left).
• Differentiate from complete physeal arrest, which would be coded differently.
• Consider co-reporting with codes for any associated deformities or limb length discrepancies.
