In 2015, CMS launched the Interoperability Roadmap, a 10-year initiative to create a unified health data-sharing ecosystem across the U.S. he U.S. As we approach 2025, the roadmap is reaching its final phases. Recent advancements like TEFCA 2.0, the Interoperability and Prior Authorization rule, and the integration of Qualified Health Information Networks (QHINs) are paving the way for a cohesive, nationwide framework. These steps bring CMS closer to achieving a secure data exchange across providers, payers, and patients.
The roadmap’s aim is to enable a healthcare environment where information flows freely, such that providers can make informed decisions for better patient outcomes. This blog explores the roadmap’s goals, recent progress, and its path to achieving full healthcare interoperability by 2025.
The Vision of the CMS Interoperability Roadmap
One of the healthcare interoperability roadmap’s central goals is to establish a learning health system—an environment where every data exchange contributes to continuous healthcare improvement. This vision supports a model where patient data is available for immediate treatment and is also used to analyze trends, personalize care, and improve health outcomes over time.
Collaboration Among Key Stakeholders
Achieving this vision requires the collaboration of multiple stakeholders—healthcare providers, payers, patients, and health IT vendors. Each group plays a role:
- Providers rely on real-time access to patient information for coordinated and informed care.
- Payers contribute by streamlining processes that improve the quality and accessibility of care.
- Patients gain control over their data to analyze the progress of their healthcare journey and make decisions.
- Health IT Vendors are responsible for the systems that make data compatible for sharing in a safe manner.

The roadmap’s initial phase sets the foundation for interoperability through the ability to send, receive, find, and use priority health data. This phase focused on basic data-sharing standards for efficient communication and connecting healthcare providers for better coordination in patient care.
Mid-Term Goals (2018-2020)
In this phase, the roadmap expanded its scope to include a broader range of data sources and users. Key initiatives aimed at increasing patient access to their health information while streamlining provider workflows. Regulations like the Interoperability and Patient Access rule were introduced to ensure that healthcare systems could securely share, and access patient data as needed.
Long-Term Goals (2021-2024)
The roadmap’s final phase establishes a learning health system where interoperability becomes the norm across all healthcare settings. Goals include real-time access to comprehensive patient data, supporting advanced analytics, and a secure, nationwide data flow. Major milestones, including TEFCA 2.0 and the integration of QHINs.
Policies and Regulations Supporting Interoperability
CMS has introduced two pivotal rules to strengthen interoperability and reduce administrative burdens in healthcare: the CMS Interoperability and Prior Authorization Final Rule and the CMS Interoperability and Patient Access Final Rule.
- CMS Interoperability and Prior Authorization Final Rule
Released on January 17, 2024, this rule prioritizes streamlined access to health information, focusing on improving prior authorization processes. By enhancing data exchange between patients, providers, and payers, this rule helps place patients at the center of their care. It mandates that impacted payers implement data-sharing provisions by January 1, 2026, with extended deadlines for certain API requirements until January 1, 2027, to accommodate stakeholder feedback. - CMS Interoperability and Patient Access Final Rule
This rule mandates the use of standardized APIs to facilitate seamless electronic healthcare data exchange. These APIs allow information flow between patients, providers, and payers, supporting patient access to their data via mobile apps or EHR systems. Additionally, CMS adopted the vocabulary and content standards established in the ONC 21st Century Cures Act final rule, ensuring consistency across platforms for a unified, patient-centered health data ecosystem.
Implementing Guide for CMS Interoperability Rule
The CMS roadmap integrates FHIR standards and the USCDI, supported by specific implementation guides and technical standards.
- API Technology and Implementation Guides (IGs)
Under the CMS Interoperability and Patient Access Final Rule, CMS mandates that Medicare Advantage, Medicaid, CHIP, and Qualified Health Plan issuers implement APIs that meet established technical standards. These APIs facilitate secure data exchange between patients, providers, and payers. The CMS Interoperability and Prior Authorization Final Rule expands on these requirements, introducing APIs for provider, payer-to-payer, and prior authorization data exchange, enhancing patient-centered care and reducing administrative burdens. - FHIR Standards and USCDI
The roadmap incorporates HL7 FHIR Release 4.0.1 as a primary standard, ensuring data consistency and compatibility across health systems. FHIR’s normative resources define how clinical and administrative data can be structured and exchanged, creating a stable foundation for interoperable applications. The US Core Implementation Guide further establishes baseline requirements, defining key data elements and profiles for comprehensive health data sharing, with mandated use of US Core Profiles for all implementations in the U.S. - SMART App Launch and OpenID Connect
CMS recommended theSMART on FHIR framework and OpenID Connect for authentication and authorization. These frameworks enable apps to securely request access to FHIR resources via OAuth 2.0, ensuring that only authorized applications can retrieve sensitive health data. - Da Vinci Project Guides
The roadmap references the Da Vinci Implementation Guides, which provide standardized approaches to data exchange for specific use cases, including:
- PDex: For exchanging clinical information when patients change payers.
- Prior Authorization Support (PAS): Facilitates automated prior authorization requests within EHR systems.
- Coverage Requirements Discovery (CRD): Allows providers to retrieve payer coverage requirements at the point of care.
These IGs help reduce redundancy, streamline processes, and ensure that all stakeholders access health information consistently and securely.
