Nondisp transverse fx shaft of unsp ulna, 7thK

This code describes a situation where a patient has a transverse fracture in the shaft of their ulna, and the fracture fragments are still in their normal anatomical position. Crucially, this code indicates that the fracture has failed to heal properly (nonunion) and the patient is presenting for follow-up care for this closed fracture. The specific ulna (left or right) is not documented.

Use this code for a patient presenting for ongoing management of a previously diagnosed, non-healing, closed transverse fracture of the ulnar shaft. This applies when the fracture has not united and the physician is assessing or treating the nonunion, such as during an office visit for monitoring, cast changes, or planning for further intervention.

• Ensure documentation clearly states "nonunion" and that the fracture is "closed."
• Verify the fracture is specifically of the "shaft" and "transverse" in nature.
• Only use this code when the laterality of the ulna is not specified in the medical record.
