Nondisp seg fx shaft of rad, unsp arm, 7thR

This code signifies a segmental fracture of the radius shaft that is not displaced, meaning the bone fragments remain in their anatomical alignment. The fracture is complicated by a malunion, indicating the bone has healed in an incorrect or deformed position, and is being treated during a subsequent encounter for an open fracture classified as Type IIIA, IIIB, or IIIC. The specific arm affected is not documented.

Use this code for follow-up care of a patient who previously sustained an open segmental radius shaft fracture (Type IIIA, IIIB, or IIIC) that has now healed with malunion. This applies when the patient is receiving ongoing treatment for the malunion or related complications, and the initial injury was to an unspecified arm.

• Ensure documentation clearly specifies a segmental fracture of the radial shaft and confirms malunion.
• Verify the encounter is for subsequent care and the original injury was an open fracture Type IIIA, IIIB, or IIIC.
• Confirm the laterality (left or right arm) is not specified in the medical record.
