Oth fx shaft of r ulna, 7thN

This code signifies a non-healing fracture of the shaft of the right ulna, specifically an open fracture of severe type (IIIA, IIIB, or IIIC). "Nonunion" indicates that the bone fragments have failed to heal together after a significant period. This condition often requires further surgical intervention.

Apply this code when documenting a patient's follow-up visit for an open right ulnar shaft fracture that has not healed. This is appropriate for encounters focused on managing the nonunion, such as evaluating for bone grafting, fixation revision, or infection control. It should be used after the initial treatment phase has concluded and nonunion has been established.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• This code is for subsequent encounters, not the initial injury or acute treatment.
• Always code any associated complications, such as osteomyelitis, separately.
