Nondisp fx of coronoid pro of l ulna, 7thM

This code signifies a non-displaced break in the coronoid process of the left ulna, which is a small bony projection at the front of the elbow joint. It specifically indicates that the fracture was initially an open fracture of type I or II, and the patient is now presenting for follow-up care due to a failure of the bone to heal properly (nonunion).

Use this code for a patient who has previously sustained an open, non-displaced fracture of the left ulnar coronoid process (Gustilo-Anderson Type I or II) and is now being treated for a documented nonunion of that specific fracture. This code is appropriate for subsequent encounters where the primary focus is the management of the unhealed fracture.

• Ensure documentation clearly states "nonunion" and specifies the left ulna's coronoid process.
• Verify the initial fracture was classified as an open fracture type I or II.
• Do not use for initial encounters or for closed fractures.
