Nondisp transverse fx shaft of humer, l arm, 7thK

This code describes a left humerus shaft fracture that runs horizontally across the bone but has not shifted out of alignment. The fracture is not healing as expected, indicating a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

This code is used when a patient with a previously diagnosed nondisplaced transverse fracture of the left humeral shaft is seen for treatment or evaluation of a confirmed nonunion. This would apply to encounters where the focus is on managing the delayed or failed healing of the fracture.

• Ensure documentation clearly specifies "nondisplaced" and "transverse" fracture type.
• Verify the laterality is "left arm" and the encounter is for a "subsequent encounter for fracture with nonunion."
• Do not use this code for initial treatment of the fracture or for routine follow-up of a healing fracture without nonunion.
