Every vendor speaks a different HL7
Message profiling, mapping and transformation on Mirth Connect, Iguana or Rhapsody, with a conformance test for every partner before go-live.
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.
100+ healthcare projects | 16+ years in healthcare | HL7 v2 · FHIR R4 · SMART on FHIR
Trusted Partners
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
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.
Message profiling, mapping and transformation on Mirth Connect, Iguana or Rhapsody, with a conformance test for every partner before go-live.
EHR-embedded app development: EHR launch, OAuth 2.0 authorization and FHIR R4 read/write, with support for the Epic, Oracle Health and athenahealth app programs.
HL7 v2 to FHIR transformation and FHIR facades over legacy systems, so both worlds connect through one layer.
Monitoring, alerting and replay for every channel, with dashboards your team can read and an on-call model that covers nights.
Patient-access APIs, Bulk FHIR, USCDI data classes and TEFCA/QHIN readiness built into the platform, not bolted on.
Dedicated interface analysts and FHIR engineers who already know Mirth, Iguana, Epic Bridges and the EHR vendors’ quirks, ramped in weeks.
OUR SERVICES
Six kinds of interoperability work, one team, built on standards and on the HL7 FHIR integration tools healthcare IT teams already run.
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.
Interface engine implementation and management
Design, build and run of the engine layer on Mirth Connect, Iguana, Rhapsody or Cloverleaf, including migration between engines and managed operations.
FHIR API development and FHIR facades
FHIR R4 APIs, servers and facades that expose clinical data to modern applications, payers and patients, whether the source system speaks FHIR or not.
SMART on FHIR app development
Applications that launch inside the EHR, use its login and read and write through FHIR APIs: the fastest route to clinician adoption for a new capability.
EHR, lab, imaging, pharmacy and payer integration
The connections a health system needs, on the standards each partner uses, through one interface layer.
Testing, monitoring and interface tooling
The tools around the interfaces: validation, simulation, monitoring and the dashboards that tell you a feed is healthy before a clinician tells you it isn’t.
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.
Named teams for Mirth Connect and Iguana, with production experience on Rhapsody and Cloverleaf. 20+ EHR, EMR and HIS integrations delivered.

interfaces
Interfaces carry protected health information between organizations that don’t share a security team. We design every integration to the regulations and API rules that apply, and can show you how, control by control.
TLS 1.2+ on every MLLP, HTTPS and API connection, mutual TLS where partners support it, and certificate lifecycle management.
OAuth 2.0 and OpenID Connect for FHIR APIs and EHR-embedded apps, with scopes limited to the resources each app needs.
Patient-access, provider-access and payer-to-payer APIs built to the ONC and CMS specifications, with USCDI data classes.
Security, policy and testing evidence prepared for QHIN participation and national-network onboarding.
42 CFR Part 2 and opt-in/opt-out rules enforced at exchange time; sensitive-data segmentation where required.
ATNA-style audit of every message, query, API call and administrative action, exportable for OCR audits.
HIPAA-eligible environments on AWS, Azure or Google Cloud with BAAs in place; high availability and tested disaster recovery; on-premise where you require it.
Third-party vulnerability assessments and penetration tests tracked to closure; conformance and load testing before every partner go-live.
Best for a set launch. Defined feeds, FHIR scope or one app, fixed price, milestone-based delivery and a clear go-live date.
Best for continuous integration work. Named interface analysts and FHIR engineers, with QA included, who work as an extension of your team.
Best for feeds you already run. Monitoring, on-call and support, kept current with vendor changes, with build capacity on call.

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.
