Nondisp spiral fx shaft of ulna, l arm, 7thM

This code signifies a left ulna shaft fracture that is spiral in nature and has not shifted from its anatomical position. The fracture was initially an open fracture of either Type I or Type II, and the current encounter addresses a nonunion, meaning the bone has failed to heal properly.

This code is appropriate for follow-up encounters where a patient with a previously treated open spiral fracture of the left ulnar shaft is being managed for nonunion. This would include situations where surgical intervention or other treatments are being performed or planned to address the delayed or failed bone healing.

• Ensure documentation clearly specifies "nonunion" for this subsequent encounter.
• Verify the fracture is indeed of the ulna shaft, left arm, and described as "nondisplaced spiral."
• Confirm the initial injury was an open fracture (Type I or II) to justify the "M" seventh character.
