Healthcare Interoperability Experts
HL7 to FHIR Converter for Healthcare Organizations
Modernize legacy HL7 systems without replacing your EHR.
Aigilx Health converts your existing HL7 v2 message streams into clean, standards-compliant FHIR R4 resources — so your applications, partners, and analytics teams get modern APIs while your clinical workflows stay exactly as they are.
- HL7 v2.x to FHIR R4 conversion
- HIPAA-aligned engineering
- No EHR rip-and-replace
- US Core profile support

The Interoperability Gap
Legacy HL7 Interfaces Weren't Built for Today's Healthcare
HL7 v2 still carries the majority of clinical data in production — but everything downstream of it now expects FHIR. That mismatch shows up everywhere:
You don't need a new EHR to become FHIR-ready. You need a conversion layer that speaks both languages fluently — and that is exactly what we build.
What We Deliver
More Than a Converter — a Complete Interoperability Layer
We don't just transform message syntax. Aigilx Health designs, builds, and operates the full pipeline that turns raw HL7 v2 events into validated, queryable FHIR resources your teams can build on.
Every engagement covers mapping, terminology, validation, monitoring, and the operational tooling that keeps clinical data flowing reliably — long after go-live.
- Bidirectional HL7 v2 ↔ FHIR R4 transformation
- Terminology mapping — LOINC, SNOMED CT, ICD-10, RxNorm
- Validation against US Core and custom FHIR profiles
- Error queues, retry logic, and message-level monitoring
- Cloud, hybrid, or on-premise deployment
- Full audit trails for compliance reporting
Why Aigilx Health
Built by Healthcare Integration Engineers, Not Generalists
Healthcare-Only Focus
Interoperability is all we do. Our engineers live in HL7 segments, FHIR profiles, and implementation guide requirements every single day.
Standards Depth
HL7 v2.x, CDA, FHIR R4, US Core, and SMART on FHIR — plus the terminology systems that bind them all together.
Faster Time to Value
Pre-built mapping accelerators for common message types mean your first converted feeds go live in weeks, not quarters.
Secure by Design
HIPAA-aligned architecture with encryption in transit and at rest, least-privilege access, and complete audit logging from day one.
Transparent Engagements
Fixed-scope discovery, clear milestones, and documentation your team actually owns — no black boxes, no lock-in.
Support Beyond Go-Live
Monitoring, upgrades, standards updates, and new-feed onboarding — all handled under one ongoing partnership.
How It Works
From Legacy Feeds to Live FHIR APIs in Five Steps
-
01
Discovery & Assessment
We inventory your HL7 interfaces, message volumes, and target use cases, then define a precise conversion scope and timeline.
-
02
Mapping & Design
Every message type is mapped to its FHIR resources, terminology bindings are agreed, and edge cases are documented up front.
-
03
Build & Validate
The conversion pipeline is built and every output is validated against your FHIR profiles using real, de-identified message samples.
-
04
Deploy & Integrate
We go live in your environment — cloud, hybrid, or on-premise — running alongside existing interfaces with zero workflow disruption.
-
05
Monitor & Evolve
Dashboards, alerting, and ongoing tuning keep data flowing reliably as your systems, volumes, and standards evolve.
The Payoff
What Changes When Your Data Speaks FHIR
| Outcome | What it means for your organization |
|---|---|
| Faster integrations | New applications connect through standard FHIR APIs in days — not months-long custom interface projects. |
| Lower maintenance cost | One managed conversion layer replaces dozens of brittle point-to-point interfaces. |
| Regulatory readiness | Meet CMS and ONC FHIR-based exchange requirements without re-platforming your EHR. |
| Unlocked analytics & AI | Clean, structured FHIR resources feed dashboards, population health tools, and ML models directly. |
| Better partner exchange | Payers, HIEs, and digital health partners connect through the standards they already support. |

FAQ
Common Questions About HL7 to FHIR Conversion
No. The conversion layer sits alongside your existing systems and translates the HL7 v2 messages they already produce. Your EHR, clinical workflows, and current interfaces continue running exactly as they do today — FHIR is added on top, not swapped in underneath.
We support HL7 v2.x (2.3 through 2.8) and CDA documents as inputs, converting to FHIR R4 and R4B with US Core profile conformance. Other implementation guides and custom profiles are supported on request, and we track evolving releases so your pipeline stays current.
Most first feeds — for example ADT or ORU messages — go live within four to eight weeks, depending on message complexity and environment access. Our pre-built mapping accelerators cover the common message types, so effort concentrates on your site-specific customizations rather than starting from zero.
Yes. Alongside HL7-to-FHIR conversion, we support FHIR-to-HL7 v2 write-back for workflows that need it — such as orders placed in a modern application flowing back to a legacy system as standard v2 messages.
All engagements follow HIPAA-aligned practices: business associate agreements, encryption in transit and at rest, least-privilege access controls, and comprehensive audit logging. The pipeline can run entirely inside your own environment, so PHI never has to leave your infrastructure.
Yes. We deploy to your cloud tenancy, a hybrid setup, or fully on-premise — whichever your security and data-residency requirements call for. You keep full ownership of the infrastructure, the data, and the documentation.
