A large health plan with 2 million members had outdated provider directory information, with over 30% being inaccurate. This led to member and provider dissatisfaction and regulatory issues. The health plan contracted with Atlas Prime to validate provider demographic data for all 150,000 provider locations. Atlas Prime made calls, sent faxes and emails, and offered self-service options to validate the data. Their process included recording all calls and archiving materials for auditing. This improved the data accuracy in the health plan's directories, increasing member and provider satisfaction while reducing complaints.
