2025: A Defining Year for Interoperability in U.S. Healthcare

In 2025, interoperability has evolved from a regulatory goal to a national imperative. With the Trusted Exchange Framework and Common Agreement (TEFCA) officially operational and CMS tightening data exchange mandates, hospitals across the U.S. are under increasing pressure to unify data across disparate systems.

According to the Office of the National Coordinator for Health IT (ONC, 2024), nearly 70% of U.S. hospitals are now engaged in interoperable exchange, yet only 43% routinely integrate outside patient data into their EHRs, highlighting persistent fragmentation. Furthermore, over 60% of hospitals report plans to join TEFCA networks by late 2025, signifying a pivotal shift toward standardized, nationwide data sharing.

FHIR (Fast Healthcare Interoperability Resources) is leading this transformation, serving as the digital “grammar” of connected care. Leading vendors like Epic Systems, Oracle Health, and MEDITECH have expanded FHIR-based APIs to support the new CMS Interoperability and Prior Authorization Rule, effective January 2026, which requires payers and providers to adopt standardized data exchange protocols for faster, patient-centered decisions.

Data Fragmentation: Still the #1 Barrier to Connected Care

Despite progress, data fragmentation continues to cost U.S. healthcare billions annually. ONC data shows 43% of clinicians still face gaps when viewing external patient records, often due to incompatible data models and incomplete patient matching. This disconnect affects not only care coordination but also compliance with CMS’s quality reporting and patient access mandates.

A 2024 KLAS Research survey revealed that over 55% of hospital CIOs cite “cross-platform integration” as their single greatest IT challenge. The burden of managing duplicate patient records and reconciling non-standard data formats consumes up to 20% of clinical administrative time- an inefficiency that undermines both care quality and financial performance. 

Pathways to True System Interoperability

Building a fully interoperable health system requires more than technology integration- it demands strategic, operational, and cultural alignment.

The following pillars define success:

• FHIR-first Architecture: Adopting HL7® FHIR-based APIs for real-time, standards-driven data exchange.
• TEFCA Participation: Engaging with Qualified Health Information Networks (QHINs) to ensure nationwide, compliant connectivity.
• Data Governance & Stewardship: Establishing enterprise-wide data quality, consent, and identity management frameworks.
• Cloud-Native Integration: Leveraging API gateways and middleware to unify legacy and modern systems seamlessly.
• AI-Driven Interoperability Monitoring: Using machine learning to detect data discrepancies and ensure compliance with CMS and ONC requirements. 

The ScaleHealthTech Interoperability as a Managed Service Framework

At the forefront of this transformation is, ScaleHealthTech interoperability as a managed service model purpose-built for the complex realities of health systems. Drawing from its healthcare-native integration expertise, the model simplifies Interface footprint, closes talent gaps and prepares CIO’s for CMS Compliance.

Aligned with TEFCA and CMS compliance protocols, the ScaleHealthTech Interoperability as a Managed Service turns interoperability into 30-40% cost savings while staying CMS ready. The model includes:

• Interoperability Navigator Assessment – a no cost readiness scan that benchmarks health system/ health plans, CMS and TEFCA readiness. Maps the interface complexity footprint. Pinpoints hidden cost drains and produces a 90 days action plan
• Run & Rationalize – Optimize existing engines ( Intersystems, Rhapsody, Mirth, Redox etc). Reduce hundreds/ thousands of interfaces to an optimal set
• Talent Pods -  Agile HL7/FHIR Engineers, EMPI specialists, architects. Burn down backlogs in 10-14 weeks. Onboard app 50% faster
• DUO Platform – Bridge system of record with system of engagement. Create an AI, automation ready FHIR Data layer

This approach enables hospitals to move from fragmented operations to a data-intelligent, compliant, and connected enterprise, bridging the gap between regulation and real-world transformation.

​​Case in Focus: Multi-Hospital Data Exchange Pilot

​A 2024 pilot led by the eHealth Exchange, one of the nation’s largest health information networks, connected 15 hospitals across three states using networked FHIR APIs to automate prior authorizations and exchange patient summaries in near real time.

According to KLAS Research’s Points of Light Case Study (2024), this initiative reduced administrative turnaround by 38%, cut redundant diagnostic testing by 27%, and improved payer-provider coordination metrics by 22% within six months.

This pilot reflects the tangible impact of TEFCA-aligned interoperability—delivering both clinical and financial ROI.

Compliance Readiness: A 2025 Checklist for Health Systems

As CMS and ONC move toward stricter interoperability mandates, health systems must ensure readiness across six key areas:

• TEFCA Participation: Confirm alignment with a QHIN or initiate onboarding.
• FHIR API Enablement: Implement and test HL7 FHIR R4 APIs for patient access, payer data, and clinical workflows.
• Patient Identity Matching: Integrate master patient index (MPI) and probabilistic matching tools to improve accuracy.
• Data Provenance Tracking: Maintain audit trails to meet CMS’s Prior Authorization and Interoperability Rule documentation requirements.
• Information Blocking Compliance: Update policies to ensure timely and secure patient data release.
• Governance Oversight: Form a cross-functional interoperability council to monitor compliance and optimization metrics.

The Road Ahead

2025 marks the tipping point for healthcare interoperability in the U.S. Hospitals that treat data as a strategic asset, not a compliance burden, will lead the next decade of value-based, connected care.As the CMS and TEFCA frameworks reshape the digital health infrastructure, ScaleHealthTech stands as an end to end transformation partner bridging technology, compliance, and care delivery through interoperability as a managed service framework. Because in modern healthcare, data connectivity isn’t optional, it is foundational.
