Use of an 8-Digit Registry Number on Clinical Trial Claims

This article is based on Change Request (CR) 5790 that notifies providers and suppliers that Medicare claims forms will be modified to accommodate the 8-digit clinical trial number for claims that Medicare receives on or after April 1, 2008. Reporting this number is voluntary and claims submitted without the clinical trial number will be paid the same as claims containing a number. While reporting is voluntary, the number will assist the Centers for Medicare & Medicaid Services (CMS) in informing beneficiaries about the availability of clinical trials and to use claims information to inform coverage decisions.
