Nondisp fx of head of unsp rad, subs for clos fx w nonunion

This code signifies a follow-up encounter for a patient who previously sustained a fracture to the head of an unspecified radius, which was initially treated without surgical intervention (closed fracture). At this subsequent visit, there is evidence that the bone fragments have not healed together properly, indicating a nonunion.

Use this code when documenting a patient's visit for ongoing management of a previously diagnosed, nondisplaced radial head fracture that has failed to unite. This applies to situations where the fracture was initially treated non-surgically, and the current encounter focuses on addressing the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the radial head as the fracture site.
• Verify the fracture was initially treated as a "closed fracture" and was "nondisplaced."
• This code is for a subsequent encounter; an initial encounter for the same injury would use a different code.
