Interoperability has long been a priority for payers; but in today’s environment, it has become a business imperative.

Recent policy and industry developments, including the 21st Century Cures Act, CMS interoperability mandates, and the operationalization of TEFCA, are accelerating the shift toward real-time, standardized data exchange. As of early 2026, TEFCA networks have enabled the exchange of hundreds of millions of health records, signaling rapid progress across the industry. A new CMS rule (CMS-0053-F) advancing standardized electronic claims attachments further extend this momentum by requiring more consistent, digital exchange of the clinical documentation that supports prior authorization and claims processing.  

Compliance may be driving initial investment, but long-term value depends on how payers apply interoperable data to improve operations, strengthen provider relationships, and reduce friction in the patient access experience.

Why Interoperability Matters Now 

Across the healthcare landscape, access has become the front door to care, and it is under increasing strain. Health systems continue to invest in access improvements, yet many face persistent challenges tied to fragmented data, administrative complexity, and misaligned workflows between payers and providers. Prior authorizations delay care. Incomplete patient histories slow decision-making. Disconnected systems create unnecessary effort for both clinicians and members.

Interoperability addresses these challenges by enabling seamless data exchange across organizations. With the right data available at the right time, payers can: 

• Support faster and more accurate eligibility and authorization decisions  

• Reduce delays in onboarding and care coordination  

• Equip providers with more complete patient information  

• Improve the overall digital front door experience  

These improvements contribute directly to better access, greater efficiency, and stronger trust across the healthcare ecosystem. 

Moving Beyond Compliance to Strategic Value 

Many organizations have historically approached interoperability as a requirement. That mindset is shifting as leaders recognize its broader strategic impact. 

Payers are increasingly using interoperability to support: 

• More actionable insights: When data moves consistently across systems, analytics and AI models can operate on more complete datasets. This leads to stronger insights for care management, network optimization, and financial performance. 

• Stronger payer-provider collaboration: Shared, timely data creates better alignment between payers and providers. This supports more effective value-based care arrangements and improves coordination across the continuum. 

• Scalable innovation: Interoperable architectures create a foundation for emerging capabilities, including real-time decision support, automation, and AI. These technologies can be layered onto existing systems without requiring large-scale replacement. 

Organizations that take this approach are building more connected and responsive operating models. 

How Interoperability Transforms Payer Operations 

To capture these benefits, payers must align interoperability investments with core operational priorities. Several high-impact use cases illustrate this connection.

1. Member Onboarding: Setting the Foundation for Access 

The member experience begins during onboarding. Access to real-time clinical data through TEFCA-qualified networks and FHIR-based APIs allows payers to develop a more complete understanding of each member from the start. This includes prior utilization, existing conditions, and anticipated care needs. 

With this insight, payers can support more effective care management and reduce delays as members enter the system. A more informed onboarding process helps create a smoother and more coordinated experience. 

2. Utilization Management: Reducing Friction in the System 

Utilization management remains a major source of administrative burden across healthcare. Standardized, automated data exchange allows payers to streamline prior authorization workflows, reduce manual review, and make faster decisions. Access to real-time clinical data supports more precise evaluations and enables the use of AI to identify low-risk cases and expand gold carding programs.

Emerging CMS requirements for standardized electronic claims attachments further accelerate this shift by enabling more consistent and automated exchange of the clinical documentation required for prior authorization and claims processing. 

These improvements reduce delays and help patients access care more quickly. 

3. Value-Based Care: Enabling Better Alignment 

As value-based care models expand, timely data sharing becomes essential. Interoperability allows payers to provide performance insights, quality metrics, and care gap information to provider partners in near real time.

This supports proactive care management and improves coordination across organizations. Better data exchange leads to stronger alignment and more effective collaboration. 

4. Risk Adjustment: Improving Accuracy and Efficiency 

Access to longitudinal clinical data enhances the accuracy of risk adjustment. Payers can use interoperable data to validate diagnoses, identify suspect conditions, and support more accurate submissions. This reduces reliance on manual chart reviews and lowers administrative burden while improving financial and clinical outcomes.

5. Internal Processes: Streamlining Operations and Access

Interoperability connects payer operations, provider workflows, and member expectations. 

When data flows seamlessly, administrative processes become more efficient, clinical decisions are better informed, and member experiences improve. These gains support a more coordinated and accessible healthcare system. 

For payers, this creates an opportunity to improve performance while delivering a more consistent experience for members and providers. 

Looking Ahead 

The shift toward real-time, API-driven healthcare data exchange is well underway. Organizations that invest in scalable interoperability strategies, supported by standards such as FHIR and frameworks like TEFCA, will be better positioned to improve access and operational performance. 

Those that delay may face increasing challenges as the healthcare system continues to evolve toward more connected, data-driven models.
