Disp fx of olecran pro w intartic extn left ulna, init

This code signifies a break in the prominent, bony tip of the left elbow (olecranon process) that has shifted from its normal position and extends into the joint space. The fracture is contained within the skin, meaning there is no open wound communicating with the bone.

This code is appropriate for the initial treatment of a patient presenting with a closed fracture of the left olecranon that clearly involves the articular surface of the elbow joint and shows displacement on imaging. This typically results from a direct blow to the elbow or a fall onto an outstretched hand.

• Confirm imaging reports explicitly state "displaced," "intraarticular extension," and "closed" for the left ulna.
• Distinguish from non-displaced fractures (S52.02-) or those without intraarticular extension.
• Ensure the encounter is the initial treatment for this specific fracture; subsequent encounters will use different seventh characters.
