Important Notice: Due to patient confidentiality issues (e.g., HIPAA requirements regarding Protected Health Information), this software should not be used via the NIST Web site for validation of messages containing real patient information. With proper precautions in place to maintain patient confidentiality, if an organization downloads the Validation Tool and uses it locally the Tool can validate messages with real patient information.



The Cancer Report Validator (CRV) is an interactive tool for validating the content of electronic submissions of cancer-related medical information prior to a system's communication with a cancer registry.

The CRV conforms to the HL7 Implementation Guide for CDA® Release 2: Reporting to Public Health Cancer Registries from Ambulatory Healthcare Providers, Release 1; DSTU Release 1.1 - US Realm.


The National Program of Cancer Registries (NPCR) is a program run by the National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP) of the Centers for Disease Control and Prevention (CDC). NPCR's mission is to collect data to monitor the burden of cancer, evaluate the success of programs, and identify additional needs for cancer prevention and control efforts at national, state, and more local levels.

In order to facilitate this goal, central cancer registries have been established to collect data from sources such as hospitals, doctors' offices, and laboratories on cancer occurrence and type of initial treatment. CRV serves as a means of verifying that the software used by doctors' offices is capable of correctly preparing Clinical Document Architecture (CDA) documents for submission. This tool only applies to the format required by Meaningful Use for physicians and it is not intended to be used for hospital or laboratory reporting.

This initiative has been sponsored by the CDC and is being managed by the Office of the National Coordinator for Healthcare IT.
