The ACCESS Model rewards outcomes. But outcomes can't be measured (or paid) without complete, auditable clinical data. This guide explains how the Health IT requirements work, why interoperability is foundational to compliance, and what you need to have in place before your patients are aligned. UNDERSTANDING THE REQUIREMENTS ## ACCESS includes three interoperability requirements The ACCESS Model introduces three Health IT requirements. The challenge isn't any single one. It's making them work as a system. REQUIREMENT 01 ### Standardized APIs FHIR-based APIs supporting patient and population services. REQUIREMENT 02: THE BRIDGE ### HIE Connectivity Bidirectional exchange across the geographies where you deliver care. REQUIREMENT 03 ### CMS Reporting FHIR-based submission of outcomes and supporting clinical data. ![git-merge-icon](https://go.metriport.com/hs-fs/hubfs/git-merge-icon.png?width=20&height=20&name=git-merge-icon.png) HIE connectivity is the bridge that makes the APIs and reporting work together.   INSIDE THE PLAYBOOK ## Four sections. Everything you need to know. **01. The Rise of Value-Based Care** How outcome-aligned payment models led to ACCESS, and what the shift means for how participants prove results. --- **02. The Three HIT Requirements** A clear explanation of what CMS requires for standardized APIs, HIE connectivity, and FHIR-based reporting, including the details that are easy to miss. --- **03. The Compliance Checklist** Six concrete steps, organized by deadline, to help participants identify gaps and prioritize workstreams before key dates pass. --- **04. The Data Imperative** Why incomplete patient records are a compliance liability, not just a clinical one, and how auditable data is the foundation of every ACCESS payment. ---   “Cercanos was built on value-based care, so when CMS announced ACCESS, we knew it was a perfect fit. Metriport was the obvious partner to work with: HIE connectivity, network reciprocity, and the clinical depth that value-based care requires.” ![Jaun Estrada MD](https://go.metriport.com/hubfs/Jaun%20Estrada%20MD.jpeg) CEO & CO-FOUNDER, CERCANOS CARE Juan Estrada, MD   Cercanos Care is a CMS ACCESS first-cohort participant serving Hispanic communities across cardiometabolic and behavioral health.

Metriport provides a single FHIR-native API for accessing and exchanging clinical data across national and regional networks, helping organizations support outcomes measurement, care coordination, and CMS reporting requirements. ![Diagram of Metriport's FHIR-native API as a central hub: inbound data from EHRs, hospitals, labs, and pharmacies flows in, and outbound connections reach care teams, referring providers, CMS reporting, and digital health platforms.](https://go.metriport.com/hs-fs/hubfs/metriport-fhir-hub-diagram.png?width=2000&height=733&name=metriport-fhir-hub-diagram.png "Diagram of Metriport's FHIR-native API as a central hub: inbound data from EHRs, hospitals, labs, and pharmacies flows in, and outbound connections reach care teams, referring providers, CMS reporting, and digital health platforms.") --- This guide is intended to support organizational readiness planning for the CMS ACCESS Model. It does not constitute legal, regulatory, or compliance advice. Organizations should review the official CMS ACCESS Model [documentation](https://www.cms.gov/priorities/innovation/files/access-rfa.pdf) and consult internal compliance stakeholders as appropriate. ![Metriport Logo White](https://go.metriport.com/hubfs/Metriport%20Logo%20White.png) Metriport 48 Colin P Kelly Jr St San Francisco, CA 94107 © 2026 Metriport All rights reserved [Privacy Policy](https://www.metriport.com/privacy-policy) [Powered by Atlas - a B2B SaaS HubSpot theme](https://www.kalungi.com/atlas-hubspot-theme-for-b2b-saas-software)
