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

This code describes a follow-up encounter for a patient with a non-displaced spiral fracture of the shaft of the ulna, where the initial injury was an open fracture classified as Type IIIA, IIIB, or IIIC. The current encounter addresses a complication of malunion, indicating the fracture has healed in an unsatisfactory position. The specific arm affected is not documented.

Use this code when documenting a subsequent visit for a patient receiving ongoing treatment for a malunited, non-displaced spiral ulnar shaft fracture that was originally an open fracture (Type IIIA, IIIB, or IIIC). This would apply to scenarios such as surgical correction of the malunion, physical therapy for functional deficits due to malunion, or follow-up imaging to assess the malunion.

• Ensure documentation clearly specifies "subsequent encounter" and "malunion" as the reason for the visit.
• Verify the original fracture was an open fracture type IIIA, IIIB, or IIIC; if not, a different code for malunion would be appropriate.
• Do not use this code for initial treatment of the fracture or for routine follow-up without malunion.
