TEFCA One Year Later: Is Nationwide Interoperability Delivering?
TEFCA promised a simpler future: one connection to exchange data nationwide with trust, security, and speed.
One year in, the momentum is clear. Multiple QHINs are live, FHIR is entering the framework in planned stages, and the on-ramp for nationwide exchange is finally taking shape.
But progress is still uneven. Many organizations are still early on FHIR maturity, and day-to-day operations in labs and provider settings continue to feel the friction of legacy interfaces, healthcare data integration, and manual workarounds.
This update breaks down where TEFCA stands today: what’s working and what’s not. We’ll also share how leaders can use TEFCA to accelerate interoperability, readiness for AI, and measurable outcomes without derailing current operations.
The state of TEFCA: What’s changed in year one
TEFCA might feel like a “box to check,” but it’s an evolving process. Here’s where it currently stands:
- QHINs are live: Networks like CommonWell, eHealth Exchange, Epic Nexus, and others have gone operational, providing a real backbone for trusted exchange.
- FHIR is rolling in by design: ONC and the RCE are taking a staged approach to bringing FHIR into TEFCA. This slowly raises the bar in manageable steps rather than a single “big bang.” That’s good for resilience, testing, and adoption.
- Reality check: FHIR competence varies widely across vendors and internal teams. Most orgs still run a patchwork of HL7 v2, CCD/C-CDA, and proprietary APIs.
TEFCA is happening, but your organization’s outcomes will depend on how quickly you align governance, standards, and APIs to the roadmap.
Where TEFCA is already delivering value
Early adopters are already seeing real gains. Here are some of the strongest impact stories from TEFCA’s first year:
- Lower integration cost for digital health companies
Startups that previously spent 3–6 months building HL7 to EHR pipelines now onboard with a QHIN in weeks.Why it matters: Faster enterprise sales, lower engineering burden, and dramatically smoother go-lives.
- Payers gain unified member histories
Cross-state patient movement no longer breaks longitudinal care visibility.Why it matters: Better risk adjustment, fewer blind spots in care management, and stronger utilization insights.
- Public health agencies finally get near-real-time data:
The Covid-era lag is disappearing as TEFCA introduces faster reporting pipelines.Why it matters: Earlier detection, faster interventions, and more accurate surveillance.
- CIOs trust vendors faster:
TEFCA alignment signals built-in governance and security.Why it matters: Shorter procurement cycles, fewer security reviews, and reduced legal friction.
- Wearables and remote device vendors gain clinical context
By merging step data, HRV, sleep stages, ECG, and other device signals with TEFCA-sourced clinical histories, companies finally deliver whole-person insights.Why it matters: AI models improve, engagement increases, and the data becomes clinically defensible.
The four stages of FHIR in TEFCA and what they mean for you
Stage 1: FHIR Content Support
This initial phase focuses on enabling FHIR content within each QHIN’s network. Think of it as “internal FHIR enablement.” QHINs can exchange FHIR payloads within their own systems and coordinate manual exchanges between QHINs “out of band.”
Example in Practice: A lab connected to the same QHIN as a hospital can share diagnostic data using FHIR. But if the lab needs to send results to a provider on another QHIN, that still requires manual coordination.
What the Industry Should Do:
- Inventory your data formats and ensure your systems can export/import FHIR resources (Observation, DiagnosticReport, Patient, etc.).
- Assess terminology mapping readiness (LOINC, SNOMED, RxNorm).
- Evaluate internal APIs for FHIR conformance and scalability.
How Pegasus One Can Help: Pegasus One performs FHIR readiness assessments, helping you identify data, API, and security gaps before moving to automated exchanges. Our AI-powered ETL and compliance accelerators reduce mapping complexity and ensure alignment with US Core profiles.
Stage 2: QHIN-Facilitated FHIR Exchange
QHINs must now support FHIR APIs for inter-network exchange, meaning data can flow between QHINs using standardized interfaces. This marks the start of automated, cross-network data exchange.
Example in Practice: A patient’s cardiology app can pull data from multiple QHINs (e.g., Epic’s Nexus and CommonWell) without manual coordination. Each QHIN exposes FHIR APIs for discovery and retrieval.
What the Industry Should Do:
- Adopt standardized FHIR APIs for outbound/inbound exchange (US Core + SMART on FHIR).
- Implement authentication frameworks (OAuth2.0, OpenID Connect).
- Prepare governance policies for patient consent and cross-network access.
How Pegasus One Can Help: We help organizations deploy secure FHIR APIs with built-in identity, consent, and token-based authentication. Our cloud-native integration frameworks simplify QHIN onboarding and audit logging for compliance.
Stage 3: QHIN-to-QHIN FHIR Exchange
In this stage, QHINs must directly exchange data using FHIR APIs. No more “out-of-band” processes. This is where true nationwide interoperability takes shape.
Example in Practice: A hospital in Michigan and a health plan in California — on different QHINs — can exchange encounter and claims data in real time for care coordination or prior authorization.
What the Industry Should Do:
- Validate inter-QHIN routing capabilities to ensure your endpoints can handle asynchronous FHIR requests.
- Test performance and latency under production load.
- Integrate monitoring and drift detection to maintain FHIR conformance.
How Pegasus One Can Help: Pegasus One builds FHIR validation and routing infrastructure that supports QHIN-level scaling. We implement API health monitoring, conformance testing, and automated drift alerts to ensure continuous compliance and reliability.
Stage 4: End-to-End FHIR Exchange
The ultimate stage — universal, end-to-end FHIR interoperability. Every participant and sub-participant (providers, payors, vendors, patients) can exchange FHIR data seamlessly across QHINs. This is where real-time national interoperability becomes a reality.
Example in Practice: A patient traveling cross-country can instantly have their full longitudinal health record accessible through any TEFCA-connected app or provider.
What the Industry Should Do:
- Integrate TEFCA participation into your enterprise data strategy.
- Enable patient-facing apps for Individual Access Services (IAS).
- Adopt continuous interoperability testing to align with evolving ONC standards.
How Pegasus One Can Help: We help organizations operationalize end-to-end interoperability through:
- FHIR-native APIs that meet TEFCA security and traceability standards
- Real-time data governance dashboards
- Workflow-native AI modules that transform interoperability into measurable clinical outcomes
Executive takeaways after year one
- TEFCA is real, but uneven: Expect a hybrid period where TEFCA coexists with legacy HIEs, vendor APIs, and direct connections. Design for “both/and,” not “either/or.”
- FHIR maturity is the differentiator: The organizations ready for Stages 2–4 will reduce interface debt and accelerate new use cases (care coordination, prior auth, patient access).
- Governance is your force multiplier: Identity, consent, auditing, and testing disciplines are what make TEFCA safe and scalable.
- Use TEFCA to advance strategy, not just compliance: Treat TEFCA alignment as a catalyst for AI readiness, workflow automation, and better patient experiences.
