Complete physeal arrest, right proximal humerus

This code signifies the premature and complete cessation of growth at the growth plate (physis) located in the upper part of the right humerus. This condition prevents further longitudinal bone growth in the affected area, potentially leading to limb length discrepancy or angular deformity.

Assign this code when documentation clearly indicates a complete arrest of the physis in the right proximal humerus. This typically occurs due to trauma, infection, or other pathological processes affecting the growth plate. Supporting documentation should include imaging reports (e.g., X-rays, MRI) confirming the complete physeal closure.

• Differentiate from partial physeal arrest, which would be coded differently.
• Ensure laterality (right) and specific bone segment (proximal humerus) are clearly documented.
• Consider sequencing this code with an external cause code if the arrest is due to an injury.
