Minimally displ Zone II fx sacrum, subs for fx w nonunion

This code signifies a minimally displaced fracture located specifically in Zone II of the sacrum, which has progressed to a nonunion. A nonunion indicates that the bone has failed to heal completely after a typical healing period, despite the fracture being initially minimally displaced. This condition requires ongoing management due to the lack of bone consolidation.

Use this code for patients presenting for follow-up care of a sacral Zone II fracture that has been previously treated but has not achieved union. This applies when the physician explicitly documents a nonunion of the fracture. It is appropriate for subsequent encounters where the nonunion is the primary focus of the visit.

• Ensure documentation clearly specifies "nonunion" and the sacral Zone II location.
• Verify the displacement is documented as "minimally displaced."
• This code is for subsequent encounters; an initial encounter would use a different code.
