HL7 Interface Development and FHIR Integration Services

QSS Technosoft builds the interfaces that get one healthcare system talking to another: HL7 v2 feeds on Mirth Connect, Iguana and Rhapsody, FHIR R4 APIs and facades, apps that launch inside Epic, Oracle Health and athenahealth, and connections to labs, imaging, pharmacy, payers and national networks.

Healthcare data still moves mostly over HL7 v2, while everything new is built on FHIR, and most hospitals will need both for years.
We know which HL7 FHIR integration tools healthcare organizations actually need for a given job, and we say so in the first meeting.

CHALLENGES INTEGRATION TEAMS FACE

What you’re up against,
and what changes when you work with us

Interface projects rarely fail on the standard. They fail on the vendor’s dialect of it, on the feed nobody monitors, on the app that needs to live inside the EHR and doesn’t. Here is where we see organizations get stuck, and how our HL7 and FHIR work is built to get them unstuck.

OUR SERVICES

HL7 Interface and FHIR Integration Services: What We Build

Six kinds of interoperability work, one team, built on standards and on the HL7 FHIR integration tools healthcare IT teams already run.

SERVICE OVERVIEW

HL7 v2 interface development

The feeds that keep a hospital running: admissions, orders, results, scheduling and documents, built on an interface engine so each new partner is configuration, not a project.

Why Healthcare Organizations Choose QSS for HL7 and FHIR Integration

Interoperability is not a feature of our healthcare practice; it is the practice. Every EHR, imaging, telehealth and RPM project we deliver runs on the same HL7 and FHIR backbone, which is why our interface analysts have seen the vendor dialects, the failed feeds and the app-program certifications before they reach your project.

Common Questions,
Expert Answers

Answers about our HL7 and FHIR integration, SMART on FHIR apps, interface engines, the HL7 FHIR integration tools healthcare teams ask about, compliance, timelines and costs.

Health Level Seven (HL7) is a set of international standards for the exchange, integration and retrieval of electronic health information. It lets healthcare systems such as EHRs, labs, billing and pharmacy software exchange structured data, which reduces manual entry and errors, speeds decisions, lowers cost and keeps organizations compliant. HL7 v2 remains the workhorse for messaging inside hospitals; HL7 FHIR is the modern API standard for anything new.

All major HL7 standards: HL7 v2.x for messaging, HL7 v3 and CDA/C-CDA for structured documents, and HL7 FHIR R4 for modern API-based data exchange, including SMART on FHIR and CDS Hooks.

AI assists with mapping and transformation drafting, message validation and anomaly detection, extraction of structured data from documents and free text, and terminology mapping, always with an interface analyst reviewing anything that touches patient data.

Yes. We transform HL7 v2 and C-CDA into FHIR resources, and build FHIR facades over legacy systems, so organizations can adopt FHIR-enabled workflows, apps and third-party integrations while preserving what already works.

HL7 Inspector, 7Edit, Inferno, Touchstone, the FHIR Validator, Postman and custom conformance suites on Mirth Connect and Iguana for schema validation, message simulation and regression testing. The technology section above lists the tools we use and where.

By applying AI to HL7 and FHIR data, including Bulk FHIR extracts, we enable predictive analytics that identify high-risk patients, track population health trends, personalize care plans and optimize resource use for value-based care.

HL7 gives disparate systems a common language. An integration layer built on it supports multi-version messaging, bidirectional exchange, real-time synchronization, parsing and validation, cloud and on-premise systems, and monitoring with audit trails, so data moves across radiology, pharmacy, billing and the EHR without re-keying.

Yes. We build HL7-compliant interfaces that connect legacy systems with modern platforms, with data normalization, real-time messaging and secure interoperability, and no need to replace existing infrastructure.

All integrations are developed to HIPAA, GDPR and the other regulations that apply, with secure transport, encryption, audit trails, role-based access and, for APIs, OAuth 2.0 and the ONC and CMS specifications.

Absolutely. We build interfaces that connect cloud-based systems such as Epic, Oracle Health (Cerner) and athenahealth with HIE platforms and national networks, for secure data sharing across providers, payers and third-party tools.

Yes. We build dashboards and monitoring tools for HL7 and FHIR interfaces that track message flows, detect anomalies and trigger alerts for failures, with automated replay where safe.

Yes. We provide ongoing support, optimization and maintenance, including engine version upgrades, performance monitoring, security patches and enhancements, as a managed service if you prefer.

SMART on FHIR is the open standard that lets an application launch inside an EHR such as Epic, Oracle Health or athenahealth, authenticate the user through the EHR’s login using OAuth 2.0, and read and write data through FHIR APIs, all in the clinician’s existing workflow. Yes, we build these apps, from clinical decision support and imaging views to documentation tools and patient-facing apps, and we support certification through the EHR vendors’ app programs. It is the fastest route to clinician adoption for a new capability.

Both, in most cases. HL7 v2 still carries the operational messaging inside hospitals (admissions, orders, results) and the systems that produce it will not change soon. FHIR is required for patient access, external exchange, analytics and any new application. We build one integration layer that speaks both and transforms between them, so you are not forced to choose or to replace what works.

It depends on what you are connecting. For HL7 v2 feeds inside a hospital, an interface engine (Mirth Connect, Iguana, Rhapsody or Cloverleaf). For modern APIs, a FHIR server or facade (HAPI FHIR or a cloud FHIR service). For apps that must live inside the EHR, SMART App Launch libraries and the vendor sandboxes. For testing, Inferno, Touchstone and the FHIR Validator. The technology section above lists the HL7 FHIR integration tools healthcare IT teams ask us about most and where each fits; we help you choose in the discovery call.

Yes. We build the EHR launch, the FHIR integration and the security model each vendor requires, and we support the app program certification process (Epic, Oracle Health, athenahealth). Vendor fees are separate; the engineering and certification evidence are ours to deliver.

Yes. We move channels from Corepoint, eGate, BizTalk or an older engine version to Mirth Connect, Iguana or Rhapsody, running old and new in parallel and cutting over partner by partner, so no feed is dropped.

Usually not. We work with the HL7 FHIR integration tools healthcare teams already own, such as Mirth Connect, Iguana, Rhapsody, Cloverleaf and cloud FHIR services, and recommend a change only when an engine is end-of-life or cannot meet the volume, FHIR support or uptime you need.
