Disp fx of coronoid pro of l ulna, 7thN

This code signifies a non-healing fracture of the coronoid process of the left ulna, which is a small bony projection on the elbow joint. The fracture was initially an open fracture of a severe type (IIIA, IIIB, or IIIC), and the bone fragments have not properly aligned or fused together. This indicates a persistent issue with bone healing following a significant injury.

Use this code for patients presenting for follow-up care, treatment, or evaluation of a previously diagnosed displaced open fracture of the left ulnar coronoid process that has failed to unite. This applies when the initial injury was classified as an open fracture type IIIA, IIIB, or IIIC, and the nonunion is confirmed. It is appropriate for encounters where management of the nonunion is the primary focus.

• Ensure documentation clearly specifies "nonunion" and the "left" ulna.
• Verify the original injury was an "open fracture" and the specific Gustilo-Anderson classification (IIIA, IIIB, or IIIC) is documented.
• This code is for subsequent encounters; a different code would be used for the initial treatment of the acute fracture.
