Nondisp oblique fx shaft of unsp ulna, 7thK

This code signifies an oblique break in the shaft of the ulna that has not shifted out of alignment. It specifically indicates that the fracture is not healing properly, leading to a nonunion, and the patient is being seen for follow-up care after the initial treatment. The exact ulna (left or right) is not specified.

Apply this code when documenting a patient encounter for ongoing management of a previously diagnosed, nondisplaced oblique ulnar shaft fracture that has failed to unite. This would include visits for assessing nonunion, planning further intervention, or monitoring conservative treatment for the nonunion.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture is described as "nondisplaced" and "oblique" in the ulnar shaft.
