Displ transverse fx shaft of humer, l arm, 7thK

This code signifies a left humerus shaft fracture that has not healed properly (nonunion) and where the bone fragments are misaligned (displaced). It indicates that the patient is receiving ongoing treatment for this specific nonunion fracture, not the initial injury.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed displaced transverse fracture of the left humeral shaft that has failed to unite. This includes visits for surgical intervention for nonunion, cast changes, or evaluation of nonunion progression.

• Ensure documentation clearly states "nonunion" and "displaced" for the left humeral shaft fracture.
• Verify that the encounter is subsequent to the initial fracture treatment.
• Do not use for initial fracture care or for malunion, which is a different complication.
