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

This code signifies a fracture of the radial head in the left arm that has not shifted from its original position. The fracture has failed to heal properly after an initial treatment, and the patient is presenting for ongoing care related to this nonunion.

This code is appropriate for follow-up encounters where a patient is being managed for a previously diagnosed, nondisplaced left radial head fracture that has not united. This includes visits for monitoring, cast changes, or discussions regarding further intervention for the nonunion.

• Ensure documentation clearly states "nondisplaced" and specifies the "left" radius.
• Verify that the encounter is "subsequent" and that "nonunion" is explicitly documented for the closed fracture.
• Do not use this code for initial encounters or for fractures that are healing normally.
