Displ oblique fx shaft of l ulna, 7thN

This code signifies a specific type of fracture involving the shaft of the left ulna, where the break is oblique and the bone fragments are no longer in their normal alignment. It indicates that the patient is receiving follow-up care for an open fracture (meaning the skin was broken) that was initially classified as a severe Type IIIA, IIIB, or IIIC, and has now failed to heal properly, resulting in a nonunion.

Use this code for patients presenting for ongoing management of a left ulnar shaft fracture that was initially open and severe, and has subsequently developed a nonunion. This would apply to encounters for surgical intervention to address the nonunion, cast changes, or other follow-up care related to the unhealed fracture.

• Ensure documentation clearly specifies "nonunion" as the reason for the subsequent encounter, not just delayed healing.
• Verify the initial open fracture type (IIIA, IIIB, or IIIC) is documented, as this code is specific to those severities.
• Confirm the fracture is of the shaft of the ulna and is oblique and displaced for accurate code assignment.
