Unsp fracture of shaft of humerus, left arm, init

This code signifies a fracture of the main body of the left humerus, where the specific type of fracture (e.g., transverse, oblique, spiral) is not documented. The skin overlying the fracture remains intact, and this encounter represents the initial treatment for the injury.

Apply this code when a patient presents for the first time with a left humeral shaft fracture, and the medical record does not specify the fracture pattern. This is appropriate for initial evaluations, emergency department visits, or inpatient admissions for the acute injury.

• Ensure documentation clearly states "left arm" and "shaft of humerus."
• Only use "unspecified" when the fracture type is truly unknown or not documented.
• The "A" suffix indicates an initial encounter for active treatment of the fracture.
