Disp fx of olecran pro w intartic extn unsp ulna, 7thK

This code signifies a fracture of the olecranon process (the bony prominence of the elbow) that has extended into the joint space and is displaced, meaning the bone fragments are not properly aligned. The "unspecified ulna" indicates the laterality (left or right) is not documented. The "subsequent encounter for closed fracture with nonunion" specifies that this is a follow-up visit for a fracture that was not open to the environment and has failed to heal after the expected time frame.

This code is appropriate for documenting a follow-up visit for a patient with a previously diagnosed olecranon fracture with intraarticular extension and displacement, where the fracture has not united. This would be used when the patient is presenting for ongoing management of the nonunion, such as evaluation for surgical intervention or continued conservative treatment.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify the fracture is explicitly described as "displaced" and with "intraarticular extension."
• Confirm this is a subsequent encounter for a closed fracture, not an initial treatment or an open fracture.
