Nondisp spiral fx shaft of ulna, unsp arm, 7thH

This code signifies a spiral fracture of the shaft of the ulna that is not displaced, affecting an unspecified arm. It specifically applies to a subsequent encounter for an open fracture of Gustilo type I or II, where the healing process is delayed.

Use this code when documenting follow-up care for a patient with a previously treated open spiral ulnar shaft fracture (Gustilo type I or II) that is now nondisplaced, but is not healing at the expected rate. This code is appropriate for ongoing management of the delayed union.

• Ensure documentation specifies "unspecified arm" if laterality is not clearly defined.
• Confirm the original injury was an open fracture type I or II and that healing is explicitly noted as delayed.
• This code is for subsequent encounters; an initial encounter would use a different code.
