We integrate your healthcare applications with leading EHR/EMR systems using their native FHIR R4 APIs — enabling bi-directional patient data exchange, real-time clinical data access, and seamless EHR workflow integration. Our team has hands-on experience with Epic’s FHIR API (R4), Oracle Cerner’s Ignite API, Athenahealth’s FHIR API, and several other major EHR platforms’ FHIR interfaces.
CMS Interoperability & Regulatory Compliance
We help US healthcare payers, providers, and healthcare IT vendors achieve compliance with the CMS Interoperability and Patient Access Final Rule (CMS-9115-F) and ONC 21st Century Cures Act Final Rule — both of which mandate specific FHIR R4 API implementations with defined timelines and enforcement mechanisms. Our compliance services cover gap assessment, FHIR API implementation, attestation support, and ongoing compliance monitoring.
HL7 v2 / CDA to FHIR Migration
Many healthcare organizations are migrating from legacy HL7 v2 messaging and CDA/C-CDA document exchange to modern FHIR R4 APIs. We provide comprehensive migration services — mapping legacy message segments and CDA sections to FHIR resources, building transformation pipelines using Mirth Connect, and implementing FHIR-based replacement interfaces that preserve all existing data semantics while modernizing the technical exchange layer.
FHIR Bulk Data & Population Health
FHIR Consulting & Implementation Strategy
Successful FHIR implementation starts with a clear strategy — understanding your use cases, regulatory requirements, technical constraints, and organizational readiness before any development begins. Our FHIR consultants help healthcare organizations define their FHIR roadmap, select appropriate implementation guides, design their FHIR server architecture, and develop the change management and governance frameworks needed for sustainable FHIR-based interoperability.
FHIR Support, Testing & Maintenance
FHIR implementations require ongoing support — as EHR vendors release API updates, implementation guides evolve, regulatory deadlines shift, and new use cases emerge within your organization. We provide structured FHIR support retainers covering production issue resolution, FHIR conformance testing, API version upgrade management, and proactive monitoring of FHIR endpoint availability and performance.
Why is FHIR the Global Standard for Healthcare Data Exchange?
FHIR (Fast Healthcare Interoperability Resources) has rapidly become the world’s leading healthcare interoperability standard — mandated by US federal regulation, adopted by leading EHR vendors, and implemented by health systems in over 50 countries. Understanding why FHIR matters is the first step toward unlocking its transformative potential for your organization.
FHIR is Built for the Modern Web
Unlike legacy HL7 v2 messaging or the complex CDA document standard, FHIR is designed around modern RESTful web APIs, JSON and XML data formats, and OAuth 2.0 / SMART on FHIR authentication — the same technologies that power every modern web and mobile application. This means healthcare developers can use familiar tools, standard HTTP clients, and open-source FHIR libraries to build integrations in days rather than months. FHIR’s developer-friendly design has catalysed an explosion of digital health innovation that was impossible under previous standards.
FHIR is Federally Mandated in the USA
The US Centers for Medicare & Medicaid Services (CMS) Interoperability and Patient Access Final Rule (CMS-9115-F) mandates that payers participating in Medicare Advantage, Medicaid, CHIP, and Qualified Health Plans expose patient data via FHIR R4 APIs. The ONC’s 21st Century Cures Act Final Rule requires EHR vendors to support FHIR-based APIs for patient and provider access. Non-compliance carries significant financial penalties. For US healthcare organizations and their technology partners, FHIR implementation is no longer optional — it is a regulatory requirement with concrete enforcement timelines and deadlines.
FHIR Eliminates Healthcare Data Silos
Healthcare has historically been characterized by fragmented, incompatible data systems — patient records locked in proprietary EHR databases, labs unable to share results electronically, payers disconnected from provider clinical data. FHIR’s standardized resource model — with defined data structures for Patients, Observations, Conditions, Medications, Encounters, Practitioners, Organizations, and 150+ other clinical concepts — creates a universal healthcare data vocabulary that enables true interoperability between previously incompatible systems, improving care coordination, reducing duplicate testing, and ultimately improving patient outcomes across the entire care continuum.
Why Mirth (Nextgen) Connect is the Ideal Platform for FHIR Integration?
Mirth Connect (now Nextgen Connect) is the world’s most widely deployed open-source healthcare integration engine, trusted by thousands of hospitals, health systems, and healthcare IT companies for HL7 v2 and FHIR-based interface development. Its combination of native HTTP connectors, JSON and XML data processing, JavaScript-based transformation engine, and FHIR-specific extension capabilities makes it the natural platform for organizations already running Mirth infrastructure who need to extend to FHIR R4.
The Mirth Connect FHIR extension acts much like the standard HTTP Listener channel but with FHIR-aware settings — enabling developers to build FHIR-compliant API endpoints, consume FHIR resources from external FHIR servers, and transform legacy HL7 v2 messages into FHIR R4 resources within the familiar Mirth channel development environment. This means organizations can leverage their existing Mirth infrastructure and interface developer skills to adopt FHIR — without requiring a complete re-platforming of their integration architecture.
Taction Software’s Mirth Connect engineers combine deep Mirth channel development expertise with FHIR R4 specification knowledge — designing FHIR integrations that are not only technically compliant but also operationally maintainable by your internal teams, with comprehensive channel documentation and monitoring dashboard configuration as standard deliverables of every engagement.

Frequently Asked Questions
Answers to the questions healthcare organizations most commonly ask when evaluating FHIR implementation and choosing a FHIR integration partner.
FHIR (Fast Healthcare Interoperability Resources) is an international standard developed by HL7 International for the electronic exchange of healthcare information. Unlike its predecessors (HL7 v2, CDA), FHIR is built on modern web technologies — RESTful APIs, JSON/XML data formats, and OAuth 2.0 authorization — making healthcare data exchange as straightforward as any web API integration. FHIR is critically important because it is now mandated by US federal regulation (CMS Interoperability Rule, ONC 21st Century Cures Act), adopted by all major EHR vendors, and enables the patient-centered, interoperable healthcare data exchange that improves care coordination, reduces waste, and empowers patients with access to their own health data.
Mirth Connect (Nextgen Connect) supports FHIR integration through its HTTP Source and Destination connectors, which handle the RESTful HTTP interactions that FHIR requires. Combined with Mirth's JavaScript transformer engine and its support for both JSON and XML data formats, Mirth Connect can receive FHIR resources via HTTP POST, parse FHIR JSON/XML payloads, transform legacy HL7 v2 messages into FHIR resources using JavaScript mappers, and send FHIR resources to external FHIR server endpoints. The Mirth Connect FHIR extension further enhances this by providing FHIR-specific channel settings and FHIR content type handling. This makes Mirth Connect an ideal platform for organizations with existing Mirth infrastructure looking to adopt FHIR without replacing their integration engine.
SMART on FHIR is an authorization framework built on OAuth 2.0 that enables third-party applications to securely access patient data from FHIR-compliant EHR systems. You need SMART on FHIR if you are building applications that need to access patient data from EHRs on behalf of patients or providers — for example, a patient engagement app that retrieves health records from a patient's hospital EHR, or a clinical decision support tool that launches within an Epic or Cerner workflow and accesses patient FHIR data. SMART on FHIR is also required for ONC certification and for publishing apps in EHR app marketplaces like Epic App Orchard and Cerner Code. If you are only building server-to-server FHIR integrations between backend systems, you may use the SMART Backend Services profile (system-level OAuth 2.0) instead.
FHIR R4 (version 4.0.1, released 2019) is the current production standard — mandated by CMS and ONC regulations and supported by all major EHR vendors. It is the version you should target for any regulatory compliance implementation. FHIR R5 (released 2023) is the latest FHIR release, introducing improvements in subscription model (Topic-based Subscriptions), permissions and consent management, cross-version analysis, and several resource refinements. While R5 is technically superior, most production implementations are on R4, and the regulatory ecosystem (US Core, Da Vinci IGs, CMS APIs) remains on R4. For new implementations, we recommend building on R4 with an architectural awareness of R5's improvements, enabling a smoother migration path when R5 adoption matures in 2026–2027.
FHIR project timelines vary significantly by scope and complexity. A focused FHIR API integration — for example, implementing a FHIR Patient and Observation read API against a single EHR — typically takes 4–8 weeks. A comprehensive CMS Interoperability compliance implementation (Patient Access API, Provider Directory API, Drug Formulary API) typically takes 12–20 weeks depending on existing data infrastructure. A full FHIR server implementation with SMART on FHIR authorization, US Core profile conformance, Mirth Connect integration channels, and ONC certification testing typically ranges from 20–36 weeks. We provide a detailed project estimate with a sprint-level breakdown after our free FHIR discovery consultation — so you have clear timeline expectations before any engagement begins.
Yes — we offer comprehensive post-implementation FHIR support retainers. FHIR integrations require ongoing maintenance because EHR vendors periodically update their FHIR API endpoints and implementation guide conformance, regulatory requirements evolve (new CMS rules, updated US Core profiles), and your own use cases expand over time. Our FHIR support retainers cover production incident response, EHR FHIR API change monitoring and integration updates, Mirth Connect channel maintenance, FHIR conformance re-testing after updates, security patch management, and new FHIR use case development. We offer 24/7 support options for healthcare organizations with critical production FHIR integration environments that cannot afford downtime in patient data exchange.
