What it means
An NCT Number (National Clinical Trial number) is the unique identifier assigned by ClinicalTrials.gov—the U.S. federal registry of clinical studies—to every registered clinical trial. It begins with 'NCT' followed by eight digits. You can search ClinicalTrials.gov by NCT number to find a study's official description, eligibility criteria, locations, sponsor, and current status. If you are considering joining a clinical trial, always confirm the NCT number matches the study your provider mentioned. Under the ACA, insurance plans may be required to cover routine care costs for patients enrolled in approved clinical trials, and the NCT number helps document your enrollment when seeking that coverage.
