The Standard

May Community Roundtable on May 27 Offers More Insight into Proposed Rule and Payer Data Exchange

As the industry prepares for the next wave of healthcare interoperability, the HL7 Da Vinci Project is dedicated to providing the community with the insights and tools necessary for success. With newly proposed regulatory frameworks, the stakes for technical and operational alignment have never been higher. Join us for the May Community Roundtable on Wednesday, May 27, 2026, from 4 – 5:30 p.m. ET to prepare for what’s next.

What You’ll Learn

While our April session established the foundational context for the new federal rule (CMS-0062-P), the May session builds on the momentum by moving from initial impressions to active implementation strategies. We will provide a focused update of the community’s considerations regarding the 2026 Interoperability Standards and Prior Authorization for Drugs proposed rule, specifically focusing on the Payer Data Exchange (PDex), PDex Plan Net, and Member Attribution (ATR) List Implementation Guides (IGs) called out in the rule.

Real-World Perspectives & Demonstrations

Following the policy discussion, you will hear directly from implementers successfully deploying these standards in real-world payer environments:

• Onyx: Discover how their implementations focus on moving data out of silos into standardized formats, providing endpoints for payers to make data available via HL7 FHIR IGs.
• Availity: Watch a live demo of core PDex workflows, including member matching and data retrieval, and learn how a centralized network can reduce onboarding friction while preserving payer autonomy and PDex semantics.

Our presenters will share critical insights on scalability and how these implementations support broader policy goals around data access, care coordination, and patient empowerment.

Upcoming Da Vinci Community Roundtable on April 29 at 4:00 pm ET

The momentum for healthcare interoperability continues to accelerate. Following the CMS-0057-F final rule, the Centers for Medicare & Medicaid Services (CMS) and the Office of the National Coordinator for Health Information Technology (ONC) have introduced its next major regulatory step: the 2026 Interoperability Standards and Prior Authorization for Drugs Proposed Rule (CMS-0062-P).

Join the HL7 Da Vinci Project for the April Community Roundtable happening on Wednesday, April 29, 2026 at 4 p.m. ET as we break down this new proposal and discuss its implications for HL7 Fast Healthcare Interoperability Resources® (FHIR®) implementation and the industry at large. The new proposed rule relies heavily on the work of the HL7 Da Vinci Project community and could bring significant changes for industry, including adding Da Vinci implementation guides to Health Insurance Portability and Accountability Act of 1996 (HIPAA) requirements.

If you’ve spent any time in healthcare over the past year, you’ve probably felt it: the energy, the urgency, the curiosity around AI. Everywhere you look, teams are experimenting with new models, exploring new use cases and imagining what care could look like if we finally had the right data in the right place at the right time.

But there’s also a shared realization emerging across the industry that AI can’t transform healthcare unless the data behind it is trustworthy, connected and interoperable.

That’s why HL7 International launched the 2026 HL7 AI Challenge, now officially open for submissions through June 30, 2026.

Why an HL7 AI Challenge?

Last year’s inaugural Challenge showed us something powerful: when innovators build on HL7 standards, they can move faster, scale more easily and create solutions that actually work in the messy, real‑world environments where healthcare happens.

Healthcare organizations around the world are experimenting with AI, but many face the same barriers: fragmented data, inconsistent formats, and limited ability to integrate AI outputs into clinical systems. HL7’s standards are designed to address these challenges, making them a natural foundation for safe and effective AI adoption.

The HL7 AI Challenge aims to:

• Encourage innovation grounded in open, widely adopted standards
• Demonstrate how structured, interoperable data improves AI performance
• Highlight real‑world solutions that can scale across organizations and borders

Healthcare interoperability has reached an inflection point.

In 2026, success is no longer defined by the presence of APIs but by the ability tooperate securely, consistently, and at scale across networks, organizations, and increasingly, across borders.

This shift reframes interoperability as something far more consequential:
a shared trust problem spanning cybersecurity, financial sustainability, and patient safety.

At the center of this transformation is FAST Security, emerging not simply as a technical specification, but as thefoundational trust layer for a global healthcare ecosystem.

Interoperability Is Now a Cybersecurity Surface

As healthcare exchange accelerates—payer-to-payer data sharing, automated prior authorization, and network-based access—organizations are no longer just exposing APIs.

They are expanding an identity and authorization attack surface.

Each new connection introduces:

• Additional credentials to manage
• Increasingly complex authorization logic
• More exceptions and edge cases
• Greater exposure to misconfiguration and attack

This is not a scaling API problem; it is a scaling trust problem.

FAST Security directly addresses this by standardizing how trust is established, enforced, and audited across organizational boundaries.

FAST Security as the Foundation of Trust Architecture

FAST Security is not designed to operate in isolation.

It provides the core trust workflows—authentication, authorization, and onboarding—that enable the broader FAST ecosystem:

• FAST Identity → Who is trusted
• FAST Security → How trust is enforced
• FAST Consent → What is permitted
• FAST Directory → Where trust is discovered

Together, these form a layered, reusable trust architecture aligned with modern interoperability demands.

This architecture allows trust to move from fragmented, one-off integrations to repeatable, scalable infrastructure.

New implementation community builds on global collaboration to improve
real-time device data exchange for AI-enabled care

Imagine a patient in an intensive care unit, monitored by a dozen devices generating streams of critical data every second.  From operating rooms and ICUs to ambulatory clinics and patient homes, clinicians and care teams rely on a growing ecosystem of medical and personal health devices. Now imagine that data is siloed, unable to flow into the EHR and unreachable by the analytics platform that might detect a dangerous trend before a clinician does.

This fragmentation is a well-known challenge in healthcare IT. On March 5, 2026, HL7 International took a major step toward solving it with the launch of the Caliper FHIR® Accelerator, a new implementation community dedicated to improving how data from medical and personal health devices is exchanged, integrated and used across healthcare systems. 

Why Caliper, and Why Now?

Caliper builds on HL7’s 2025 work with founding members to define a collaborative community focused on device interoperability. The need is clear: healthcare organizations are generating more high‑frequency device data than ever, but too often this information cannot flow cleanly into EHRs, analytics platforms or AI‑driven applications.

By leveraging HL7 FHIR alongside established device communication frameworks, Caliper aims to create a scalable, standards‑based foundation for real‑time device data integration. The goal is simple but transformative: ensure that data from critical care equipment and patient‑facing technologies can be shared consistently, reliably and safely.

“Healthcare systems are entering a new phase where access to high-quality, real-time data is essential to safely deploying advanced analytics and AI,” said Rachel Dunscombe, CEO of HL7 International. “The Caliper Accelerator represents an important step forward in ensuring that device-generated data, whether from critical care equipment or patient-facing technologies, can be shared and used consistently across care environments worldwide. This kind of foundational interoperability is critical to improving both clinical outcomes and operational resilience.”

Upcoming Da Vinci Community Roundtable on February 25 at 4:00 pm ET

As the federal government signals stronger enforcement and clearer expectations for healthcare pricing transparency, the ability for patients to make informed decisions has become a cornerstone of modern care efforts. The HL7® Da Vinci Project Community Roundtable, taking place on February 25, 2026, from 4 – 5:30 p.m. ET, will bring together the pioneers who are turning these regulatory expectations into reality.

The January roundtable set the stage for 2026 by focusing on overall use case progress and adoption readiness. This February session, “Navigating Patient Cost Transparency Using HL7 FHIR: Insights from Industry Leaders,” zooms in on Patient Cost Transparency (PCT), moving from the "why" of transparency to the "how" of implementation. Attendees will hear directly from early adopters about how they are navigating the complexities of Good Faith Estimates (GFE) and building the infrastructure for a more patient-centric ecosystem.

The upcoming 90-minute session will focus on:

• The Evolving Transparency Landscape: An overview of how recent federal actions and the No Surprises Act are driving an industry effort to increase transparency and empower patients.
  
• Standardizing Good Faith Estimates: Insights into the HL7 FHIR-based approach to PCT and how it automates the exchange of cost data between providers and payers.
• Real-World Pilot Progress: First-hand accounts from Aetna/CVS Health and Kyruus Health on how they are leveraging FHIR along with their existing infrastructure and previous work to streamline implementation of PCT, as well as lessons learned.
• The Role of Innovative Apps: How standardized data enables accurate, real-time access to medical costs via consumer-facing applications prior to the delivery of care.
• Collaboration Strategies: What organizations should keep in mind when working in an ecosystem-based solution, where it’s not just one group involved but a whole mix of partners that need to collaborate for success.

How States Can Move From Fragmented Programs to Shared, Scalable Infrastructure Using FAST

The CMS Aligned Networks Pledge marks a clear inflection point in federal health IT policy. For the first time, Centers for Medicare & Medicaid Services (CMS) is not simply setting compliance requirements for individual programs—it is asking the healthcare ecosystem to operate as connected networks, capable of secure, real-time, standards-based data exchange across payers, providers, public health and patients.

For states, this shift is significant.

States are no longer just one participant among many. They are increasingly the anchor for trust, identity, consent and directory infrastructure that enable CMS-aligned networks to function at scale. Medicaid programs, state CIO offices and HIEs sit at the intersection of policy, operations and technology. The CMS Aligned Networks Pledge makes that role explicit.

This blog explains:

1. What the CMS Aligned Networks Pledge really changes for states
2. Why traditional, program-by-program approaches will not scale
3. How the  HL7® FHIR® at Scale Taskforce (FAST)  provides the infrastructure states can reuse across initiatives
4. How states can leverage existing systems and vendors without starting over

The CMS Aligned Networks Pledge: A Shift from Programs to Infrastructure

Historically, CMS initiatives have been implemented as discrete programs:

• A new reporting requirement
• A new API mandate
• A new exchange use case
• Trusted digital identity and patient matching
• Scalable security and partner onboarding
• Computable, portable consent
• Authoritative directories for endpoint discovery

The CMS Aligned Networks Pledge represents a different expectation.

CMS is signaling that future interoperability depends on shared infrastructure capabilities, including:

• Trusted digital identity and patient matching
• Scalable security and partner onboarding
• Computable, portable consent
• Authoritative directories for endpoint discovery

These are not features of a single application. They are ecosystem functions.

For states, this means success is no longer measured by whether a single system goes live, but by whether multiple programs can reuse the same trust and exchange foundations.

Those of us working across health policy, technology, and standards are reimagining a system where individuals experience better outcomes, lower costs, and greater trust in how their health information is used and shared.

At HL7® International, a global standards development organization with members and affiliates in more than 50 countries, we are meeting our challenge head-on through collaboration and innovation. The HL7® FHIR® at Scale Taskforce (FAST) Accelerator takes that mission further by tackling the hard problems of scalability: Identity, Security, Consent, and National Directory services. These components are the backbone that supports the CMS Health Tech Ecosystem and Aligned Networks Pledge.

Paired with the Da Vinci Project, which applies FHIR to payer–provider workflows like prior authorization, clinical data exchange, payer data exchange, and patient cost transparency. HL7 is aligning infrastructure with real-world use cases. Da Vinci has recognized the value of FAST standards by selecting FAST Security as part of their security recommendations in their core health record exchange (HRex) specifications, showing a convergency across the ecosystem.

Where Sequoia’s RCE Role Elevates the Work: TEFCA as the National Trust Layer

FAST isn’t building infrastructure in a vacuum. Its work aligns with the Trusted Exchange Framework and Common Agreement (TEFCA), led by The Sequoia Project as the Recognized Coordinating Entity (RCE) for ASTP/ONC. TEFCA is a national framework for the secure and trusted exchange of clinical data across networks.

The HL7® Da Vinci Project is extending the deadline to nominate outstanding contributors for its 2025 Community Champions recognition program. Community members now have until Friday, February 6, 2026, to submit nominations, giving an extra week to spotlight colleagues and collaborators who are making a real impact on healthcare interoperability.

The Community Champions program honors individuals from across the Da Vinci Project's diverse, multi-stakeholder ecosystem, including health plans, provider organizations, accountable care organizations (ACOs), and health IT vendors. As an HL7® FHIR® Accelerator, the Da Vinci Project brings together public and private sector leaders to advance standards that support automated workflows, real-time data exchange, reduced administrative burden and improved care coordination.

Since launching in 2020, the Community Champions program has recognized individuals who embody a spirit of “industry above self.” Champions are known for their collaboration, leadership, and commitment to advancing real-world adoption of HL7 FHIR standards in support of value-based care and a more connected healthcare system.

HL7 International has announced the appointment of Patrick (Pat) McGinn, MBA, CAE, as its new Chief Operating Officer (COO), strengthening the organization’s leadership team during a pivotal period of transition.
