There are no specific ECDS guidelines for auditor approval of ECDS data sources. Data sources must meet the ECDS requirements and must be reputable—containing accurate, complete and reliable clinical data. Auditors use the same validation methods as for all other data sources. For example, for claims data, auditors validate the accuracy and completeness of the plan’s claims data. For a case management system, auditors review the system, the processes for capturing data and whether data can be extracted from the system. NCQA will add guidance to audit requirements as we learn more about data sources being used.
