Unsp physl fx upper end humer, r arm, subs for fx w malunion

This code describes a fracture of the growth plate (physis) at the top of the right humerus that was not specified in its exact type, and is now presenting for follow-up care where the fracture has healed in an abnormal position (malunion). This indicates a previous injury to the growth plate that has resulted in a deformity.

Use this code for a patient presenting for a follow-up visit related to a previously sustained, unspecified physeal fracture of the right humeral upper end, where imaging or clinical assessment confirms malunion. This would be appropriate for ongoing management, evaluation of functional limitations, or planning for corrective procedures due to the malunion.

• Ensure documentation clearly states "malunion" and specifies the right arm and upper end of the humerus.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
• Verify that the original fracture type was indeed "unspecified" if no further detail is available from prior records.
