HL7 Interface Messaging Services
Expert development of every HL7 message type used in clinical and administrative healthcare workflows — built for reliability, accuracy, and long-term maintainability.

What We Do
We develop, transform, and route every major HL7 v2 message type — with the clinical and technical expertise to get it right the first time.
ADT Message Development
Patient admission, discharge, transfer, and demographic update messaging (A01-A60). We build inbound and outbound ADT interfaces for EHRs, bed management, lab, pharmacy, and care coordination systems.
ORU Result Messaging
Lab results, radiology reports, pathology, and other clinical observations (ORU R01). We build result routing interfaces that deliver accurate, timely results to EHRs and clinician workflows.
ORM/OML Order Messaging
Lab, radiology, and medication order messages from ordering systems to fulfillment systems — and result-back workflows. Full order lifecycle management including order cancellation and modification.
SIU & MDM Messaging
Scheduling notifications (SIU S12/S13/S14/S15) for appointment management and Medical Document Management (MDM T02) for transcription, discharge summaries, and clinical notes routing.
How It Works
Message Flow Analysis
We map your clinical and administrative workflows to identify which HL7 message types are needed and how messages should be routed between systems.
Interface Specification
We create detailed field-level mapping specifications for each message type, including segment requirements, field formats, and transformation rules.
Development & Testing
We build message transformation logic, routing rules, and ACK handling — then test with real message samples and EHR sandbox environments.
Production Monitoring
Post go-live, we monitor message volumes, error rates, and processing times — with alerting for failed messages and connection issues.
Why Choose Our HL7 Messaging Team
Deep Message-Level Expertise
Our engineers have built interfaces for every major HL7 v2 message type across hundreds of healthcare organizations — we know the edge cases, the EHR quirks, and the clinical nuances.
Reliable ACK Handling
Proper acknowledgment handling (AA, AE, AR) with retry logic and dead-letter queues ensures no message is lost and every failure is visible to your team.
Clinical Validation Built In
We include clinical review as part of every interface delivery — ensuring that message content is clinically accurate, not just technically valid.

Frequently Asked Questions
What is the difference between HL7 interface messaging and HL7 integration?
HL7 interface messaging refers specifically to the development of individual HL7 message pipelines (ADT, ORU, ORM, etc.) — the point-to-point connections between specific systems. HL7 integration is the broader discipline that encompasses messaging architecture, integration engine selection, routing strategy, and the overall interoperability program.
How do you handle HL7 message errors and failures?
We implement multi-layered error handling: NACK (negative acknowledgment) detection with configurable retry logic, dead-letter queuing for messages that cannot be delivered, error alerting to operations teams, and detailed logging for post-incident analysis.
Can you build fan-out messaging — one message to multiple destinations?
Yes. Fan-out messaging (broadcasting a single HL7 message to multiple downstream systems) is a common pattern we implement frequently — for example, sending an ADT A01 from an EHR to lab, pharmacy, care management, and bed management simultaneously.
