Unsp fx shaft of r ulna, 7thN

This code signifies a previously diagnosed, unspecified fracture of the shaft of the right ulna that was an open fracture of type IIIA, IIIB, or IIIC, and has now failed to heal properly (nonunion). It indicates a follow-up encounter for ongoing management of this complicated healing process.

Use this code for patients presenting for follow-up care of an open right ulnar shaft fracture (initially classified as IIIA, IIIB, or IIIC) that has progressed to nonunion. This applies when the patient is receiving treatment for the nonunion, such as bone grafting, internal fixation revision, or other interventions aimed at promoting healing.

• Ensure documentation clearly states nonunion of a previously open right ulnar shaft fracture (type IIIA, IIIB, or IIIC).
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the laterality (right ulna) and specific bone involved.
