Disp fx of head of right radius, subs for clos fx w malunion

This code signifies a previously treated fracture of the head of the right radius that was displaced, and is now presenting with malunion. Malunion indicates that the bone has healed, but in an unsatisfactory or deformed position, which may lead to functional impairment.

Use this code when a patient is seen for follow-up care of a healed, but improperly aligned, displaced fracture of the right radial head. This applies to situations where the initial treatment for the fracture has concluded, and the current encounter addresses the complications of its healing.

• Ensure documentation clearly states "malunion" and specifies the "right" radius.
• Verify that this is a "subsequent encounter" and not an initial treatment or active nonunion.
• Always check for laterality (right vs. left) and the specific bone (radial head) to ensure accurate coding.
