S59.109A
ICD-10-CMUnspecified physeal fracture of upper end of radius, unspecified arm, initial encounter for closed fracture
This code signifies a fracture of the growth plate (physis) at the upper end of the radius bone, near the elbow. The specific location or type of physeal fracture is not documented, and the affected arm is also not specified.
Apply this code when a patient presents with a newly diagnosed, closed physeal fracture of the proximal radius, and the medical record lacks detailed information regarding the fracture's precise location (e.g., Salter-Harris type) or laterality. This is appropriate for the initial treatment encounter when further diagnostic clarity is pending.
