4-part fracture of surgical neck of unsp humerus, init

This code signifies a complex fracture involving four distinct fragments at the surgical neck of the humerus, the constricted area just below the humeral head. This injury typically results from significant trauma and can lead to considerable pain and functional impairment of the shoulder.

Apply this code for the initial treatment of a newly diagnosed, closed 4-part surgical neck fracture of the humerus when the laterality (left or right) is not documented. This is appropriate for the emergency department visit, initial hospitalization, or first physician encounter for this specific injury.

• Ensure documentation clearly specifies a "4-part" fracture of the surgical neck.
• Only use this code when the humerus laterality is truly unspecified in the medical record.
• Verify the encounter is for the initial treatment of the closed fracture. Subsequent encounters will require a different seventh character.
