HL7 and FHIR integration

HL7 and FHIR integration services for healthcare systems

Connect EHRs, healthcare applications, and downstream systems with interfaces designed around real clinical and operational workflows.

A technical question or early-stage idea is enough to start. No budget or timeline is required.

Capabilities

From technical discovery to production support

We can own a focused piece of work or stay with the implementation from architecture through go-live and support.

HL7 v2 interfaces

Design and implement message flows around the events, mappings, acknowledgments, and exceptions your workflow requires.

  • ADT, ORM, ORU, SIU, and MDM workflows
  • Field, component, and Z-segment mapping
  • ACK/NAK handling, validation, and routing

FHIR APIs and applications

Use FHIR resources and APIs to connect modern applications to healthcare data and clinical workflows.

  • FHIR R4 resource mapping
  • REST API and webhook integration
  • SMART on FHIR application workflows

EHR and system connectivity

Bridge EHRs, portals, labs, billing platforms, analytics systems, and custom applications.

  • Epic, athenahealth, NextGen, and Oracle Health workflows
  • Integration engine and API architecture
  • Bidirectional and event-driven data exchange

Testing and operations

Validate data behavior before launch and make interface health visible after production cutover.

  • Message samples and test scenarios
  • Error queues, logs, and alerting
  • Runbooks, documentation, and support
Typical deliverables

A useful handoff, not a black box

Your team gets the implementation details, operational visibility, and documentation needed to own or support what goes live.

  • Interface specification covering systems, message events, mappings, security, and ownership
  • HL7 mapping documents or FHIR resource mappings with representative test data
  • Implemented and tested channels, API connections, routing logic, and error handling
  • Production monitoring, runbooks, operational documentation, and support handoff
Frequently asked questions

Questions teams ask before starting

What is the difference between HL7 v2 and FHIR?+

HL7 v2 commonly exchanges event-driven messages between healthcare systems, while FHIR exposes healthcare data as structured resources through modern web APIs. Many real environments use both, and the right choice depends on the systems, workflow, and data access model.

Which HL7 message types can you implement?+

Common work includes ADT patient events, ORM orders, ORU results, SIU scheduling, and MDM document messages. We can also work with custom mappings, Z-segments, acknowledgments, and organization-specific interface requirements.

Can you connect our application to an EHR?+

Yes. We can help design and implement EHR connectivity using HL7, FHIR, vendor APIs, integration engines, or a combination of approaches based on the EHR and the workflow your application supports.

Do you support interfaces after go-live?+

Yes. Support can include monitoring, error investigation, mapping changes, new message scenarios, documentation, upgrades, and escalation procedures for production interfaces.
