Oth disp fx of lower end of right humerus, init for opn fx

This code signifies a break in the lower portion of the right upper arm bone (humerus) that is not a supracondylar, intercondylar, or condylar fracture, and the bone fragments are out of their normal alignment. The fracture has broken through the skin, exposing the bone, and this is the initial treatment encounter for the injury.

Apply this code for patients presenting with a newly diagnosed, open, displaced fracture of the distal right humerus that does not fit more specific anatomical classifications (e.g., supracondylar). This is used for the initial surgical or non-surgical management of the open fracture.

• Ensure documentation clearly specifies "displaced" and "open fracture" for accurate code assignment.
• Verify the fracture location is the lower end of the humerus and not a more specific type (e.g., supracondylar) to avoid miscoding.
• The "B" seventh character indicates an initial encounter for an open fracture, meaning active treatment is being provided.
