Physeal arrest, other site

This code signifies the premature cessation of growth at the epiphyseal plate (growth plate) in a bone site other than those specifically classified elsewhere. This condition can lead to limb length discrepancies or angular deformities due to the affected bone ceasing to lengthen while surrounding bones continue to grow. It represents a growth disturbance impacting skeletal development.

Use this code when documentation clearly indicates a physeal arrest occurring in a bone not covered by more specific codes (e.g., not a radius, ulna, tibia, or fibula). This diagnosis is typically supported by imaging studies (X-rays) showing a growth plate closure or bridge, along with clinical findings of growth disturbance.

• Ensure the documentation specifies a site other than those with more specific physeal arrest codes.
• Do not confuse with epiphyseal fractures (S-codes) unless a physeal arrest is a documented sequela.
• Consider sequencing this code after any underlying cause (e.g., trauma, infection) if applicable and still active.
