Displ seg fx shaft of ulna, unsp arm, 7thF

This code signifies a follow-up encounter for a patient who sustained a segmental fracture of the ulna shaft, which is displaced and open (classified as Type IIIA, IIIB, or IIIC). The fracture is located in an unspecified arm and is currently healing routinely.

Apply this code for subsequent visits where a patient with a previously diagnosed open, displaced segmental ulna shaft fracture (Type IIIA, IIIB, or IIIC) is being monitored for routine healing. This includes follow-up appointments for cast changes, wound care, or imaging to assess progress, provided no complications are present.

• Ensure documentation specifies an open fracture type IIIA, IIIB, or IIIC and routine healing for subsequent encounters.
• Do not use this code for the initial encounter; a different code would be assigned for the initial injury.
• Verify the fracture is segmental and displaced; other fracture types or displacement statuses require different codes.
