Oth nondisp fx of lower end r humer, subs for fx w nonunion

This code signifies a fracture of the lower portion of the right humerus that is not displaced and has failed to heal properly after an initial treatment. The "nonunion" indicates that the bone ends have not united and are unlikely to do so without further intervention. This is a follow-up encounter for this specific complication.

Apply this code when documenting a patient presenting for ongoing management of a previously treated, nondisplaced fracture of the distal right humerus that has developed a nonunion. This would be used after the initial encounter for the fracture and after the nonunion has been diagnosed.

• Ensure documentation clearly states "nonunion" and specifies the right humerus and its lower end.
• Verify that the fracture was initially nondisplaced.
• This code is for subsequent encounters, not the initial treatment of the fracture.
