Displ spiral fx shaft of ulna, l arm, 7thK

This code signifies a left ulna shaft fracture that is spiral in nature and has shifted from its normal alignment. Importantly, the fracture has not healed properly (nonunion) and the patient is presenting for follow-up care after initial treatment, with the fracture still closed.

This code is appropriate for subsequent encounters when a patient with a previously treated, closed spiral fracture of the left ulnar shaft is diagnosed with nonunion. It would be used when the patient is receiving ongoing management for this specific complication, such as evaluation for surgical intervention or continued conservative treatment.

• Ensure documentation clearly states "nonunion" for this specific fracture.
• Verify the fracture is of the ulna shaft, not the distal or proximal end.
• Confirm the encounter is "subsequent" and the fracture remains "closed."
