Healthcare Interoperability Challenges
Healthcare interoperability initiatives often stall due to legacy complexity, fragmented data, and poorly governed integrations. HL7 and FHIR standards alone do not guarantee reliable data exchange without a structured integration approach.
Organizations typically face:
- Disconnected EHR, EMR, LIS, and billing systems
- Legacy HL7 interfaces lacking documentation and ownership
- Inconsistent clinical and administrative data across platforms
- High operational and compliance risk during integration changes
- Slow onboarding of new healthcare systems and partners
Our healthcare interoperability services address these challenges through controlled HL7 and FHIR integration delivery.
HL7 & FHIR Integration Services
We deliver end-to-end healthcare data integration services covering both legacy and modern interoperability standards.
Design and implementation of stable HL7 interfaces for real-time and batch healthcare data exchange, including message parsing, transformation, routing, validation, and reconciliation across clinical and administrative systems.
Normalization and transformation of clinical and administrative data between HL7, FHIR, and proprietary formats to ensure consistency, data quality, and operational reliability.
Stabilization and modernization of outdated HL7 integrations through reverse engineering, refactoring, and phased migration toward FHIR-based interoperability architectures without disrupting patient care.
Implementation of FHIR-based interoperability using secure APIs, including HL7-to-FHIR mapping, FHIR resource modeling, SMART on FHIR integrations, and controlled access to clinical data for internal and third-party systems.
Setup, configuration, and optimization of healthcare integration engines to support high message volumes, monitoring, logging, and predictable performance in production environments.
Secure healthcare data exchange with access control, audit logging, traceability, and ongoing production support to meet regulatory and operational requirements.

What to Expect When You Start
Interoperability Discovery
We start with a focused discovery phase to understand how healthcare data currently moves across your systems and where interoperability risks exist. This step establishes a shared understanding between business and technical stakeholders before any integration work begins.
During discovery, we:
- Review existing HL7 and FHIR interfaces and data flows
- Identify connected systems such as EHR, EMR, LIS, billing, and external platforms
- Assess data exchange reliability, ownership, and documentation gaps
- Clarify compliance, security, and operational constraints
The result is a clear, practical view of your current interoperability landscape, including risks, dependencies, and improvement opportunities.
Integration Architecture & Roadmap
Based on discovery findings, we design a healthcare interoperability architecture that supports both current operations and future growth. This step translates integration complexity into a clear, manageable plan.
This phase includes:
- Defining how HL7 and FHIR standards will be applied across systems
- Designing data mapping and transformation strategies
- Identifying legacy components requiring stabilization or modernization
- Creating a phased integration roadmap with dependencies and priorities
You receive a realistic integration plan that reduces uncertainty and supports informed decision-making.
HL7 & FHIR Implementation
With the architecture in place, we move into controlled implementation of HL7 and FHIR integrations. The focus is on building stable, production-ready healthcare data exchange aligned with real workflows.
Implementation typically covers:
- HL7 interface development and customization
- FHIR API implementation and HL7-to-FHIR mapping
- Integration engine configuration and optimization
- Secure data exchange and access control setup
All integrations are built and tested against real-world scenarios to ensure accuracy and operational stability.
Validation & Production Readiness
Before production release, we validate that healthcare interoperability works reliably under operational conditions. This step minimizes disruption and reduces post-launch risk.
Validation activities include:
- Message validation and data consistency checks
- Error handling and recovery testing
- Performance and load verification
- Security, access, and audit readiness review
This ensures HL7 and FHIR integrations are ready for continuous, dependable operation.
Operational Support & Optimization
After go-live, we support and optimize your healthcare interoperability ecosystem to ensure long-term stability and scalability. This phase focuses on sustaining reliable data exchange while reducing internal operational load.
Ongoing support includes:
- Monitoring and incident resolution
- Performance tuning and optimization
- Adaptation to system changes and new integration needs
- Continuous improvement of integration reliability
The result is a maintainable, scalable interoperability environment that evolves with your healthcare systems.
FAQ
The timespan required for completing HL7 integration services varies from weeks to months because of many factors, including:
- The number of systems and message types to implement
- Legacy software limitations
- Technical documentation and a data source map
- Custom requirements
The foremost types of HL7 messages are related to data transfer, submission, appointment scheduling, and more.
