The accuracy of noninvasive vascular studies depends on the knowledge, skill and experience of the technologist and interpreter. Consequently, the providers of interpretations must be capable of demonstrating documented training and experience and maintain documentation for post-payment review.

All noninvasive vascular diagnostic studies must be either (1) performed by a trained physician, or (2) performed under the general supervision of a trained physician by a technologist that has demonstrated minimum entry level competency by being credentialed in vascular technology, and/or (3) performed in laboratories accredited in vascular technology.

When the physician is not the sonographer, appropriate and required technologist certification is: the Registered Vascular Technologist credential from the American Registry for Diagnostic Medical Sonography (ARDMS), with specialization in the body part studied, or, the Registered Vascular Specialist (RVS) credential from the Cardiovascular Credentialing International (CCI). These requirements will be deferred for two years (until April 10, 2008) for the office practices of cardiologist, radiologists and vascular surgeons, where the supervising physician both reviews the quality of testing and interprets the test.

Appropriate laboratory accreditation includes the Intersocietal Commission for the Accreditation of Vascular Laboratories (ICAVL), or the American College of Radiology (ACR).
