Disp fx of olecran pro w/o intartic extn r ulna, 7thN

This code signifies a non-healing fracture of the olecranon process (the bony prominence of the elbow) on the right arm. The fracture is displaced, meaning the bone fragments are out of alignment, and does not extend into the joint. This specific code is used when the initial injury was an open fracture of a severe type (IIIA, IIIB, or IIIC), and the bone has failed to unite after treatment.

Apply this code for follow-up encounters where a patient with a previously treated severe open olecranon fracture of the right ulna is diagnosed with nonunion. This indicates a complication where the fracture has not healed properly. It is used when the patient is receiving ongoing care for this specific nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right ulna's olecranon process.
• Verify the original fracture was an open fracture classified as type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter for this specific nonunion would use a different code.
