Oth physl fx upr end humer, unsp arm, subs for fx w nonunion

This code signifies a fracture of the growth plate (physis) at the top of the humerus, the long bone of the upper arm, where the specific type of physeal fracture is not further detailed. The fracture is located in an unspecified arm and is currently experiencing nonunion, meaning the bone fragments have failed to heal together after a previous treatment. This code is used for subsequent encounters for the ongoing management of this nonunion.

This code is appropriate for documenting follow-up visits for a patient with a previously diagnosed physeal fracture of the proximal humerus that has not healed. It should be used when the physician is assessing or treating the nonunion, such as for monitoring, planning further intervention, or managing complications related to the lack of healing.

• Ensure documentation clearly states "nonunion" and specifies a subsequent encounter for the fracture.
• Verify that the fracture is indeed a physeal fracture of the upper end of the humerus, as opposed to other types of humeral fractures.
• Do not use this code for initial encounters or for fractures that are healing normally.
