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

This code signifies a fracture of the growth plate at the top of the radius bone in the forearm, where the specific type of physeal fracture is not documented. It indicates that the fracture is in the process of healing poorly, specifically with nonunion, and the patient is presenting for follow-up care related to this ongoing issue. The affected arm is not specified in the medical record.

Use this code for a patient presenting for a subsequent visit for a previously diagnosed, unspecified physeal fracture of the proximal radius that has failed to heal properly. This applies when the physician documents nonunion and the laterality of the injury was not recorded. This code is appropriate for ongoing management of the nonunion, such as casting changes, physical therapy, or surgical planning.

• Ensure documentation clearly states "nonunion" and that this is a subsequent encounter for the fracture.
• Only use this code when the specific type of physeal fracture and the affected arm are not specified in the medical record.
• Always review the entire medical record for more specific details regarding the fracture type or laterality before defaulting to an "unspecified" code.
