Displ oblique fx shaft of unsp ulna, 7thK

This code describes a situation where a patient has a fracture in the shaft of their ulna, specifically an oblique fracture that is displaced. The key aspect is that this is a subsequent encounter for a closed fracture, and the fracture has failed to heal properly, resulting in a nonunion.

Use this code for follow-up visits where a patient with a previously diagnosed closed, displaced, oblique ulnar shaft fracture is being treated for a nonunion. This applies when the ulna is not specified as left or right.

• Ensure documentation clearly states "nonunion" for a closed, displaced oblique ulnar shaft fracture.
• Verify the encounter is subsequent to the initial fracture treatment.
• Confirm the laterality of the ulna is not specified in the medical record.
