HL7 v2 Channel Design
ADT, ORM, ORU, DFT, SIU, and MDM message handling over MLLP. Custom Z-segment support, dialect normalization, and high-throughput routing using Mirth Connect and equivalent integration engines.
Interface engineering
HL7 & FHIR Integration Services for Healthcare Practices
Custom HL7 v2 channel design, FHIR REST endpoint mapping, and bidirectional message routing — engineered by the same team that runs the Medmio platform in production. Scoped, priced up-front, delivered against a written runbook.
Scope your integration
What we build
Healthcare integration, end to end.
Interfaces between the EHR you already use, the billing systems you already trust, and the clearinghouses you already submit to — engineered, tested, and supported.
FHIR REST Endpoint Mapping
FHIR R4 resource mapping for Patient, Encounter, Observation, Procedure, Claim, and Coverage. SMART on FHIR for app launch, OAuth 2.0 authentication, and bulk data via the $export operation.
Bidirectional Message Routing
End-to-end message transport between EHR, practice management, billing, and clearinghouse. Failed-message replay, idempotent retry logic, and audit logging built in — the operational glue most integration vendors skip.
Custom EHR Dialect Engineering
Non-standard HL7 dialects, legacy practice management systems, proprietary billing exports, and home-grown integration layers that nobody else wants to touch. Bring the spec; we’ll scope it.
EHR compatibility
Pre-built connectors for most modern EHRs.
If your EHR isn’t on the list and it speaks HL7 or FHIR, we can integrate it — just bring the spec.

+ custom dialects
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
30-minute call to scope your EHR, message types, clearinghouse, and any custom HL7 dialect. We come back inside one business day with a written proposal.
2
Mapping & Build
Channel design, message-type mapping, transformation rules, and integration engine configuration. Built against your test environment with daily progress updates.
3
Test & Validate
End-to-end testing with real (de-identified) message volume, failed-message replay, idempotency checks, and a documented validation report your team signs off on.
4
Go-Live & Support
Production cutover with on-call coverage during the first 7 days. Hand-off runbook plus a defined support tier — monitoring, monthly reviews, or full operational ownership.
Frequently Asked Questions
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.
