The current challenges of acquiring historical data

As you acquire new members, you need to know as much as possible about their clinical, claims, encounter, and prior authorization history. Historical data can inform care management, ensure continuity of care, create more targeted member experiences, and support operational priorities like risk adjustment and quality measures.

But, acquiring historical data from other payers is challenging, fraught with inefficient, manual processes and inconsistent data formats—leading to high administrative costs for your team. Similarly, it can be just as arduous to share your member data with other payers with whom you share concurrent or prior members.

1up Health makes it easy to exchange data with other payers

Designed to meet CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F) requirements and leveraging industry standards, the 1up Payer-to-Payer Data Exchange API lets you easily and securely exchange member data with other payers in a standardized format—eliminating manual processes and administrative costs.

Our FHIR®-based API allows you to share and receive health data with other payers for new and previous members who have opted into data sharing, excluding cost-sharing and remittance dollar amounts. Incorporating data from other payers gives you a complete view of your member base and supports more informed and efficient decision-making.
