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

This code signifies a follow-up encounter for a patient with a spiral fracture of the ulna shaft that was initially nondisplaced. Crucially, the fracture has not healed as expected (nonunion) and is being managed non-surgically (closed fracture). The specific arm affected is not documented.

Apply this code when a patient presents for ongoing treatment of a previously diagnosed nondisplaced spiral ulna shaft fracture that has failed to unite, and the treatment does not involve surgical intervention. This is appropriate for subsequent visits after the initial treatment of the fracture.

• Ensure documentation clearly states "nonunion" and that the fracture is being treated as "closed."
• Verify that the encounter is for follow-up care, not the initial treatment of the fracture.
• If the specific arm (left or right) is known, a more specific code should be selected.
