To define the frequency of physician self-referral for diagnostic imaging studies.
High-volume radiographic (n=65) and ultrasound (US) (n=29) procedural codes in claims filed by Pennsylvania Blue Shield subscribers were analyzed to determine private-office (nonhospital) utilization of these examinations by radiologists and nonradiologists during 1991.
A total of 787,703 radiographic and 159,281 US claims were filed.
Nonradiologists self-referred 550,878 radiographic examinations (69.9%) and 99,931 US examinations (62.7%). Patterns of utilization varied considerably by anatomic category: The imaging studies with the highest rates of utilization by nonradiologists were skeletal radiography, vascular US, and obstetric and pelvic US.
