Displ transverse fx shaft of humer, unsp arm, 7thP

This code signifies a transverse fracture of the humeral shaft that has not healed correctly (malunion) and is displaced. The specific arm affected is not documented. This diagnosis is being made during a follow-up visit after the initial treatment of the fracture.

This code is appropriate for use when a patient presents for ongoing management of a previously treated transverse humeral shaft fracture that has healed in an unsatisfactory position. This would typically be documented in an orthopedic or physical therapy follow-up note where malunion is identified and addressed.

• Ensure documentation clearly states "malunion" and that the fracture is of the humeral shaft and transverse.
• Verify that the encounter is for follow-up care of the fracture, not the initial treatment.
• If the laterality (left or right arm) is specified in the medical record, a more specific code should be selected.
