FHIR Integration Services
End-to-end FHIR R4 integration for US healthcare — connecting EHR APIs, transforming HL7 v2 data, enabling payer exchange, and building HIPAA-compliant data pipelines.
Our FHIR Integration Capabilities
From EHR API connections to payer data exchange — we handle the full spectrum of FHIR integration challenges for US healthcare organizations.
EHR FHIR API Integration
Connect your application to Epic, Cerner, athenahealth, eClinicalWorks, and other EHR FHIR APIs — handling authentication, rate limits, pagination, and error recovery.
- ✓Epic FHIR R4 API integration (read/write, all resource types)
- ✓Cerner FHIR R4 and Millennium API connectivity
- ✓athenahealth and eClinicalWorks FHIR endpoint integration
- ✓OAuth 2.0 / SMART on FHIR token management
- ✓Rate limit handling, exponential backoff, and retry logic
- ✓FHIR resource pagination ($next bundle traversal)
HL7 v2 to FHIR Transformation
Automated real-time and batch conversion of HL7 v2.x messages to FHIR R4 resources using Mirth Connect — with bidirectional mapping and validation.
- ✓ADT A01–A60 → Patient / Encounter / Location resources
- ✓ORM / ORU → ServiceRequest / DiagnosticReport / Observation
- ✓SIU → Appointment / Schedule / Slot resources
- ✓DFT / BAR → Claim / ChargeItem resources
- ✓Bidirectional mapping (FHIR back to HL7 v2 for legacy systems)
- ✓Z-segment extension handling and custom field mapping
Payer-to-Payer FHIR Data Exchange
CMS interoperability rule compliant payer-to-payer data exchange — member attribution, prior authorization, explanation of benefits, and care gap data via FHIR APIs.
- ✓CMS-0057-F interoperability rule compliance implementation
- ✓FHIR Patient Access API (claims, EOB, clinical data)
- ✓Provider Access API and Prior Authorization FHIR API
- ✓Da Vinci PDex implementation guide support
- ✓Member consent management for data sharing
- ✓Payer enrollment and disenrollment data flows
HIPAA-Compliant FHIR Pipelines
Design and implement HIPAA-compliant FHIR data pipelines — encrypted transport, audit logging, minimum necessary PHI scoping, and BAA-backed infrastructure.
- ✓TLS 1.2/1.3 encryption on all FHIR transport channels
- ✓PHI data flow mapping and minimum necessary scoping
- ✓FHIR AuditEvent resource logging for all PHI access
- ✓Role-based SMART scopes limiting data exposure
- ✓BAA-compatible cloud infrastructure (AWS, Azure, GCP)
- ✓HIPAA gap analysis and remediation for FHIR environments
FHIR Analytics & Bulk Data Integration
Population health analytics pipelines using FHIR Bulk Data Export — connecting FHIR servers to data warehouses for reporting, quality measures, and risk stratification.
- ✓FHIR Bulk Data Access implementation (Group/$export)
- ✓NDJSON to Parquet/Delta Lake conversion pipelines
- ✓Integration with Snowflake, Databricks, BigQuery, Redshift
- ✓FHIR-native quality measure (FHIR QM) evaluation
- ✓HEDIS measure data extraction via FHIR
- ✓Real-time FHIR subscription feeds to analytics platforms
FHIR Subscription & Event Streaming
Real-time FHIR event notifications using FHIR R4B/R5 Subscriptions — push-based notifications to webhooks, WebSockets, and messaging platforms for care coordination workflows.
- ✓FHIR R4B / R5 Subscription resource implementation
- ✓Webhook (REST-hook) and WebSocket notification channels
- ✓Topic-based subscription filtering (SubscriptionTopic)
- ✓Encounter start/end, lab result arrival, medication dispensing triggers
- ✓Integration with Azure Event Grid, AWS SNS, and Kafka
- ✓Delivery guarantees and dead-letter queue handling
Frequently Asked Questions
Which FHIR implementation guides do you support?
We support US Core, Da Vinci PDex, Da Vinci PAS (Prior Auth), CARIN Blue Button, mCODE (oncology), QI-Core, and custom IGs. We also help organizations develop and publish their own FHIR IGs.
Can you integrate FHIR with our existing HL7 v2 infrastructure?
Yes. Using Mirth Connect and custom mapping engines, we build bidirectional bridges between your legacy HL7 v2 interfaces and FHIR R4 APIs — so both old and new systems can coexist.
Do you offer FHIR integration for smaller clinics and practices?
Absolutely. We work with organizations of all sizes — from single-provider practices to large health systems. We scope projects to match your budget and integration complexity.
How do you handle FHIR version mismatches between systems?
We implement translation layers between FHIR STU3 and FHIR R4, handle structural maps, and manage version negotiation at the API level. Content negotiation and version-aware routing are standard parts of our integration architecture.
