Section 6003 of the Patient Protection and Affordable Care Act (“PPACA”) makes a change to the IOASE exception that impacts physician practices providing certain radiology services in their offices. Specifically, Section 6003 provides that, with respect to referrals for magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), and other advanced imaging services as determined, the referring physician must inform a patient in writing at the time of the referral that the patient may obtain the service from a person other than the referring physician or someone in the physician’s group practice, and the referring physician must provide the patient with a list of suppliers who furnish the service in the area in which the patient resides.[5]
