Other physeal arrest of forearm

This code signifies a premature cessation of growth in the epiphyseal plate (growth plate) of the forearm bones (radius and/or ulna) due to causes other than trauma, infection, or congenital anomalies. This can lead to limb length discrepancies or angular deformities as the unaffected bones continue to grow.

Apply this code when documentation specifies a non-traumatic, non-infectious, and non-congenital growth arrest in the forearm's growth plate. This is often seen in metabolic disorders, radiation exposure, or idiopathic cases affecting the physis. Supporting documentation should clearly state the forearm as the affected site and rule out other common etiologies.

• Ensure the documentation specifies "other" causes for the physeal arrest, differentiating it from traumatic or congenital arrests.
• Do not confuse with codes for epiphyseal fractures or congenital malformations of the forearm.
• Always sequence this code after any underlying systemic condition (e.g., metabolic disorder) if it is the cause of the physeal arrest.
