EHR, FHIR & HL7 Integration Services

Overview

EHR / FHIR / HL7 Integration, done the Emorphis Health way

Interoperability projects fail on the details — mismatched terminologies, brittle interface engines, and undocumented edge cases. We build integrations that are standards-conformant, tested against real EHR sandboxes, and maintainable long after go-live.

When health systems and digital health vendors hire an EHR integration company, the real cost usually isn't the initial build — it's the undocumented interface nobody can safely modify a year later. Our FHIR API development and HL7 integration services are delivered with full mapping documentation and sandbox-validated testing against Epic, Cerner, and athenahealth, so your interoperability layer stays maintainable as your systems evolve.

Sandbox-Validated

Tested against the EHR sandbox, not just the spec

Standards conformance on paper doesn't guarantee a clean integration. We validate every interface against Epic, Cerner, and athenahealth sandbox environments before go-live.

Built to Maintain

Interfaces someone else can maintain

Undocumented HL7 mappings become a liability the day the original engineer leaves. We deliver full interface specifications and monitoring dashboards as part of every engagement.

FAQ

Common questions about EHR / FHIR / HL7 Integration

Which EHR platforms have you integrated with directly?

Our teams have hands-on delivery experience with Epic, Cerner, and athenahealth, alongside broader HL7 v2/v3 and FHIR R4 work across smaller and regional EHR systems.

Do you support both HL7 v2 and FHIR in the same project?

Yes, many engagements involve bridging legacy HL7 v2 ADT/ORU feeds with newer FHIR R4 APIs during an EHR migration or modernization phase.

How do you handle terminology mismatches between systems?

We build SNOMED CT, LOINC, and ICD-10 crosswalks as part of the interface design, with mapping tables reviewed by clinical informatics stakeholders before go-live.

What happens if an interface breaks after go-live?

Message-level monitoring and alerting are part of standard delivery, paired with documented runbooks so your team — or ours under a support agreement — can diagnose and resolve issues quickly.

How much does FHIR or HL7 integration cost?

Cost depends on message volume, number of endpoints, and whether legacy HL7 v2 interfaces need to be bridged to FHIR — we scope cost after an interface assessment of your source and target systems.

How do I hire an EHR integration company?

Start with an interface assessment covering your EHR platform, message types, and volumes, so we can propose a standards mapping and sandbox testing plan before development begins.

Do you build SMART on FHIR apps that launch inside Epic or Cerner?

Yes, we develop SMART on FHIR apps that launch in-context from Epic, Cerner, and athenahealth, using OAuth2-based authorization against each vendor's app orchard.

How long does a typical EHR integration project take?

Timelines vary by scope, but many single-EHR interface projects move from assessment to sandbox-validated go-live within a few months, depending on message complexity.
