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

This code signifies a specific type of fracture in the ulna bone, located in the forearm. It describes a spiral break in the shaft of the ulna that has shifted out of alignment, in an arm that is not specified as left or right. The "subsequent encounter for closed fracture with nonunion" indicates that the patient is receiving follow-up care for this fracture, which was initially closed (skin intact), but has failed to heal properly.

Use this code for patients presenting for ongoing treatment of a previously diagnosed, displaced spiral ulna shaft fracture where the bone fragments have not united. This applies when the initial injury was a closed fracture and the specific arm (left or right) is not documented. This code would be appropriate for clinic visits, imaging studies, or surgical interventions aimed at addressing the nonunion.

• Ensure documentation clearly states "nonunion" for a closed fracture.
• Verify the fracture is specifically a "spiral" type in the "shaft" of the ulna and is "displaced."
• Only use this code when the laterality of the arm is not specified in the medical record.
