FHIR API Development & HL7 Integration Services

Healthcare interoperability is no longer optional. The 21st Century Cures Act requires certified EHRs to expose FHIR R4 APIs for patient access and third-party app integration. TEFCA mandates FHIR support for health information network participation. Organizations that lack a mature FHIR and HL7 integration strategy are falling behind on compliance, losing app ecosystem opportunities, and operating with fragmented clinical data. Taction builds FHIR R4 API implementations, SMART on FHIR applications, HL7v2-to-FHIR migration solutions, and ONC-compliant interoperability infrastructure — giving healthcare organizations the integration foundation they need to meet regulatory requirements and support modern application development.

Tailored Services, Personalized Results

Who We Work With

Health systems and hospitals

Meeting ONC information blocking requirements, enabling patient access APIs, and connecting third-party applications to existing Epic, Oracle Health, Allscripts, or athenahealth environments.

Digital health startups

Building SMART on FHIR applications that launch inside EHR workflows and access patient data without custom integrations for each health system.

Payers

Implementing FHIR-based member access APIs, provider directory APIs, and drug formulary APIs required under CMS interoperability rules.

Health information exchanges

Upgrading legacy HL7v2 infrastructure to FHIR-based query and subscription models for modern HIE participation.

Our FHIR Implementation Process

Assessment (2–3 weeks) — Current state analysis of existing HL7v2 interfaces, FHIR readiness gaps, ONC compliance status, and integration architecture review.

Design (2–3 weeks) — FHIR resource modeling, API security design, terminology mapping, and migration sequencing plan.

Development (8–20 weeks) — FHIR server build or configuration, SMART on FHIR authorization setup, HL7v2-to-FHIR transformation channels via Mirth Connect, and API endpoint development.

Validation (2–4 weeks) — FHIR conformance testing using HL7 FHIR Validator and Touchstone, security penetration testing, and ONC compliance verification.

Go-Live and Support — Phased cutover with HL7v2 fallback, production monitoring, and ongoing support for API versioning and regulatory updates.

Frequently Asked Questions

HL7v2 is message-based (pipe-delimited text over TCP/MLLP) designed for real-time clinical event messaging. FHIR is API-based (JSON/XML over HTTP/REST) designed for modern app integration and patient data access. Most organizations need both running in parallel during a phased migration — HL7v2 for real-time clinical transactions, FHIR for patient-facing and third-party application access.

Yes. ONC requires certified health IT to support FHIR R4 APIs for patient access and provider data exchange. TEFCA further mandates FHIR support for health information network participation. Organizations that fail to implement compliant FHIR APIs are subject to information blocking penalties.

Yes. We build FHIR integrations with Epic (Open Epic FHIR), Oracle Health (Millennium FHIR), Allscripts (FHIR R4), and athenahealth (FHIR APIs) — using each platform’s published APIs and App Orchard or equivalent marketplace frameworks where applicable.

A focused FHIR patient access API implementation takes 8–12 weeks. A full HL7v2-to-FHIR migration for a multi-system environment takes 4–9 months depending on the number of interfaces and complexity of data transformation requirements.
