Interface engineering

HL7 Interface & FHIR Integration Services

An HL7 interface is the data pipe that keeps your EMR, billing system, and clearinghouse in sync — patients, orders, and charges moving automatically. We design, build, and run them: scoped, priced up-front, delivered against a written runbook.

Scope your integration
What we build

Healthcare integration, end to end.

Between the EHR, billing system, and clearinghouse you already use — engineered, tested, supported.

HL7 v2

HL7 v2 Channel Design

ADT, ORM, ORU, DFT, SIU & MDM over MLLP — custom Z-segments and dialect normalization included.

FHIR

FHIR REST Endpoint Mapping

FHIR R4 mapping for Patient, Encounter, Claim & Coverage — SMART on FHIR, OAuth 2.0, bulk $export.

Routing

Bidirectional Message Routing

EHR ↔ billing ↔ clearinghouse transport with failed-message replay, idempotent retries, and audit logging.

Custom

Custom EHR Dialect Engineering

Legacy systems, proprietary exports, and HL7 dialects nobody else will touch. Bring the spec; we’ll scope it.

EHR compatibility

Pre-built connectors for most modern EHRs.

Not on the list but speaks HL7 or FHIR? Bring the spec.

How we deliver

Four-step engagement, written runbook.

Standard integrations ship in 2–6 weeks. Custom dialects in 6–12. You know which bucket you’re in before we start.

1

Discovery

A 30-minute scoping call; written proposal inside one business day.

2

Mapping & Build

Channel design and transformation rules, built against your test environment with daily updates.

3

Test & Validate

End-to-end testing with real (de-identified) volume and a validation report your team signs off.

4

Go-Live & Support

Production cutover with 7-day on-call, a hand-off runbook, and a defined support tier.

Frequently Asked Questions

An HL7 interface is the connection that lets two healthcare systems exchange clinical and billing data automatically — patient registrations (ADT), orders (ORM), results (ORU), and charges (DFT) — using the HL7 messaging standard. In practice it’s a configured channel on an integration engine (such as Mirth Connect) that receives messages from one system, transforms them, and routes them to another, so your EMR, billing system, and clearinghouse stay in sync without manual re-entry.

HL7 v2 is the legacy messaging standard used by virtually every EHR for transactional data exchange — ADT, ORM, ORU, DFT message types over MLLP. FHIR is the newer REST/JSON-based standard better suited to web-era applications, mobile apps, and modern integrations. Most production healthcare integrations still use HL7 v2 for high-volume transactional traffic; FHIR is more common for newer point-to-point integrations. Medmio’s interface engineering team builds both.

Standard integrations into mainstream EHRs (Athenahealth, eClinicalWorks, Epic, Cerner, NextGen) ship in 2–6 weeks from contract to production. Custom HL7 dialects, legacy practice management systems, or non-standard clearinghouse connections take 6–12 weeks. We scope every engagement against a written runbook before kickoff so you know which bucket you’re in.

Pre-built connectors include Athenahealth, eClinicalWorks, Epic, Cerner, NextGen, Greenway Health, AdvancedMD, Kareo, DrChrono, Practice Fusion, Allscripts, and more. If your EHR speaks HL7 or FHIR — and virtually every modern EHR does — we can integrate it. For unusual or legacy systems we build a custom interface.

No. Our HL7/FHIR integration services are available as a standalone professional services engagement. Many clients use us purely for interface engineering between their existing EHR, billing system, and clearinghouse — no Medmio platform involved. See all services for the full scope of what our team delivers.

Yes. All interfaces are built to HIPAA and HITECH standards: encryption in transit (TLS 1.2+), encryption at rest (256-bit AES), signed Business Associate Agreement, audit logging, and access controls. Production infrastructure runs in AWS environments under BAA. See our privacy and security policy for details.

Have an integration nobody else can ship?

Bring us the EHR, the clearinghouse, the legacy billing system, the custom HL7 dialect. We’ll scope it, price it, and put a written runbook in your hands — usually within a week.
