Unsp physl fx upr end rad, left arm, subs for fx w nonunion

This code signifies an unspecific fracture of the growth plate located at the top of the radius bone in the left arm. The fracture has not healed properly, and this encounter is for ongoing management of that nonunion. The exact nature of the physeal fracture is not documented.

Apply this code when a patient presents for follow-up care of a previously diagnosed, unspecified growth plate fracture of the proximal left radius that has failed to unite. This would include situations where surgical intervention for nonunion is being planned or conservative management for nonunion is continuing.

• Ensure documentation clearly states "nonunion" and specifies the left arm.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Do not use if the specific type of physeal fracture (e.g., Salter-Harris type) is known; instead, use a more specific code.
