Answer: You may report 77073 (Bone length studies [orthoroentgenogram, scanogram]) for CT scanograms.
The descriptor doesn't specify a modality (CT or x-ray), and the code best describes the service rendered, so 77073 is the accurate choice.
You also won't change how you code based on the number or type of views, although with x-ray scanograms, you often see four exposures, with views of the hip, leg, knee, and ankle used to measure the long bones to assess growth patterns.
