Disp fx of coronoid pro of unsp ulna, 7thG

This code signifies a fracture of the coronoid process, a small bony projection on the ulna, that is no longer in its anatomical position. The injury is to an unspecified ulna (left or right is not specified), and the patient is in a phase of recovery where the fracture is not healing at the expected rate, but the skin remains intact over the fracture site.

Apply this code for follow-up encounters where a patient with a previously diagnosed displaced coronoid process fracture of unknown laterality is experiencing delayed union. This is appropriate when the fracture is still closed, meaning there is no open wound communicating with the fracture.

• Ensure documentation specifies "delayed healing" for a closed fracture.
• Verify the fracture is indeed displaced; if not, a different subcategory is needed.
• This code is for subsequent encounters, not the initial treatment of the fracture.
