Effective January 1, 2014, the Centers for Medicare & Medicaid Services (CMS) will require inclusion of an 8-digit clinical trial number on claims associated with clinical trial participation. Clinical trial related claims submitted to Medicare for dates of services on or after January 1, 2014, will be returned to the provider if the 8-digit clinical trial number is not present.

The 8-digit clinical trial number, also called the National Clinical Trial (NCT) Number or Clinical Trials identifier (IDE number), can be found on the ClinicalTrials.gov website.
