Partial physeal arrest, right distal humerus

This code signifies an incomplete cessation of growth at the growth plate (physis) located at the lower end of the right upper arm bone (humerus). This condition can lead to limb length discrepancies or angular deformities if not addressed. It indicates that the growth plate has not fully closed, but its growth has been partially inhibited.

Apply this code when documentation specifies a partial physeal arrest affecting the distal portion of the right humerus. This diagnosis is often made following radiographic imaging (e.g., X-rays) demonstrating an irregular or prematurely closing growth plate. Use this code for conditions like post-traumatic growth arrest or growth plate damage from infection or other etiologies.

• Ensure laterality (right) and specific bone (humerus) are clearly documented.
• Distinguish from complete physeal arrest, which would use a different code.
• Look for documentation of the cause of the arrest, if known, for potential additional coding.
