Nondisp transcondy fx unsp humerus, subs for fx w nonunion

This code describes a fracture that extends across the condyles of the humerus, the lower end of the upper arm bone, without any displacement of the bone fragments. The fracture is located in an unspecified humerus (either left or right). This particular code is used when the patient is receiving follow-up care for this fracture, and there is evidence that the bone is not healing properly (nonunion).

This code is appropriate for use in outpatient or inpatient settings when a patient with a previously diagnosed nondisplaced transcondylar humerus fracture presents for ongoing management of a confirmed nonunion. This includes scenarios such as follow-up appointments, imaging studies to assess healing progress, or preparations for surgical intervention due to the nonunion.

• Always confirm the laterality of the fracture (left or right) if documented; if not specified, the "unspecified" code is appropriate.
• Ensure documentation clearly states "nonunion" for the subsequent encounter.
• Do not use this code for initial encounters or for fractures that are healing normally.
