Unsp fx shaft of left radius, subs for clos fx w nonunion

This code signifies a non-healing fracture located in the shaft of the left radius, which was initially a closed fracture. "Nonunion" indicates that the bone fragments have failed to unite after a sufficient period, requiring further intervention or monitoring. This is a subsequent encounter, meaning the patient is returning for follow-up care related to this ongoing issue.

Use this code for patients presenting for follow-up appointments, evaluations, or treatment of a previously diagnosed closed fracture of the left radial shaft that has not healed. This applies when the physician explicitly documents nonunion of the fracture. It would be appropriate for scenarios such as assessing the need for bone grafting, revision surgery, or continued conservative management of the nonunion.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for a closed fracture of the left radial shaft.
• Verify the laterality (left) and the specific bone involved (radius shaft).
• Do not use this code for initial encounters or for fractures that are healing normally or with delayed union.
