Disp fx of lateral epicondyl of unsp humer, init for opn fx

This code signifies a fracture where a piece of bone has been pulled away by a tendon or ligament (avulsion) from the outer bony prominence of the upper arm bone (humerus), specifically the lateral epicondyle. The fracture is displaced, meaning the bone fragments are not in their normal alignment, and it is an open fracture, indicating a break in the skin communicating with the fracture site.

This code is appropriate for the initial treatment of a patient presenting with an open avulsion fracture of the lateral epicondyle of an unspecified humerus. This often occurs due to a sudden, forceful contraction of muscles attached to this area or a direct impact. It should be used for the first encounter where definitive treatment for the fracture is initiated.

• Ensure documentation clearly specifies an "open" fracture and "displaced" avulsion of the lateral epicondyle.
• Verify laterality (left or right) is not documented; otherwise, a more specific code should be chosen.
• Confirm this is the "initial encounter" for treatment of this specific fracture. Subsequent encounters will require different seventh characters.
