Disp fx of coronoid pro of l ulna, 7thM

This code describes a fracture of the coronoid process of the left ulna that is no longer in its anatomical position. It specifically indicates that the fracture was initially an open fracture (Type I or II) and has failed to heal properly, requiring further medical attention.

Use this code for a patient presenting for follow-up care, such as cast changes, wound care, or evaluation of nonunion, after an initial open fracture of the left ulnar coronoid process. This applies when the fracture fragments are displaced and the initial injury involved a break in the skin.

• Ensure documentation clearly specifies "left" ulna and "coronoid process."
• Verify the initial injury was an "open fracture type I or II" and that "nonunion" is documented.
• This code is for subsequent encounters; an initial encounter for this specific injury would use a different code.
