The Maryland Self-Referral Law:Â History and Implications

Many previous studies have shown that nonradiologist physicians who can refer advanced MRI and CT examinations to themselves or within their practices use these modalities at a much higher rate than those who refer their examinations to unaffiliated radiology facilities. This led Maryland to pass a unique self-referral law in 1993 to directly address self-referred advanced imaging. The authors discuss the politics and economics of self-referral and provide a comprehensive review of the creation, progression, and impact of this landmark law.
