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

This code signifies a fracture of the olecranon process (the bony prominence at the tip of the elbow) on the left ulna that has not shifted out of alignment. Crucially, the fracture line extends into the elbow joint itself, and this is the patient's first presentation for this specific injury. The skin over the fracture remains intact.

This code is appropriate for documenting an initial encounter for a patient presenting with a closed, non-displaced fracture of the left olecranon that involves the articular surface of the elbow. This would typically be diagnosed via X-ray or other imaging studies following an acute injury. It is used when the patient is receiving initial treatment for the fracture.

• Confirm "initial encounter" status; subsequent care for the same fracture will use a different seventh character.
• Verify "closed fracture" status; open fractures have distinct coding.
• Ensure documentation explicitly states "intraarticular extension" and "nondisplaced" for accurate code assignment.
