Welcome to Acentra Health Interoperability Solution – Sandbox
Breaking down Healthcare Barriers by Empowering Patients, Informing Providers and Enabling Payers.
CMS aims to deliver on the promise of interoperability through two key regulations: the Interoperability and Patient Access Rule (CMS-9115-F) and the Interoperability and Prior Authorization Final Rule (CMS-0057-F). To help payers meet CMS mandates, Acentra Health Interoperability Solution enables secure, standards-based APIs that facilitate the movement of data across the healthcare ecosystem—from payer systems (producers) to patients, EHR/EMR systems, and other payer systems (consumers)—accessible via third-party applications and clinical systems.
The solution supports Patient Access, Provider Directory, Provider Access, and Payer-to-Payer Data Exchange, and enables CMS-0057-F mandated workflows through HL7® Da Vinci APIs, including Coverage Requirements Discovery (CRD), Documentation Templates and Rules (DTR), Prior Authorization Support (PAS), and Clinical Data Exchange (CDex).
The Interoperability Solution leverages the CARIN Common Payer Consumer Dataset (CPCDS) as a foundation, along with industry-recognized standards such as HL7® FHIR®, the United States Core Data for Interoperability (USCDI), and CMS-recommended implementation guides (IGs). Together, these capabilities ensure compliance with CMS regulations while enabling scalable, secure, and interoperable data exchange across the healthcare continuum.


Sandbox Environment
The Sandbox Environment provides a secure, standards-based testing platform with synthetic yet reliable datasets for Claims, Encounters, and Provider Directory data. The dataset is representative of real-world scenarios and supports testing of Patient Access and Provider Directory APIs, as well as Provider Access, Payer-to-Payer, and HL7® Da Vinci APIs, including CRD, DTR, PAS, and CDex. This enables developers and partners to seamlessly test integrations, exercise end-to-end workflows, and ensure regulatory compliance.
