Displ spiral fx shaft of ulna, r arm, 7thR

This code signifies a right ulna shaft fracture that is spiral in nature, displaced, and has previously been treated as an open fracture (Type IIIA, IIIB, or IIIC). The current encounter addresses a malunion, meaning the bone has healed in an incorrect anatomical position.

Apply this code when documenting follow-up care for a patient with a malunited spiral fracture of the right ulnar shaft, specifically when the initial injury was an open fracture of severe type. This is appropriate for subsequent encounters where the malunion is being managed, such as for evaluation, treatment planning, or surgical correction of the malunion.

• Ensure documentation clearly specifies "malunion" and the right arm.
• Verify the original injury was an open fracture type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters, not the initial treatment of the fracture.
