Do your engineers handle integration-engine migrations between vendors?

Yes. Migrating from Rhapsody to Mirth, Cloverleaf to Corepoint, or any combination is a common engagement, typically run as fixed-scope migrations with a parallel-run period before cutover.

Hire Dedicated HL7 Integration Engineers in the USA

Despite a decade of FHIR adoption, HL7 v2 is still the lingua franca of U.S. healthcare data exchange. Lab results, admissions, transfers, discharges, orders, and pharmacy messages still flow as HL7 v2 inside almost every hospital. The engineers who built those interfaces in the 2010s are retiring. The engineers entering the field are learning FHIR, not HL7 v2. The result: every hospital integration team is hiring HL7 engineers, and almost no one can find them.

Taction Software’s HL7 integration engineers have shipped against HL7 v2.3, v2.5, v2.5.1, and CDA, across hospital systems, lab networks, imaging centers, and pharmacy chains. They bridge HL7 v2 to FHIR R4 when modernization is the goal, and they keep legacy HL7 v2 pipelines stable when migration is not. Engagements start at $8,000 per engineer per month with a 14-day onboarding window and a Business Associate Agreement signed before any PHI touches our systems.

Why HL7 v2 Engineering Is a Scarce Specialty in 2026

HL7 v2 is one of the oldest active healthcare standards still in production, and the skill stack to work with it is harder to find every year:

What We Screen For Before Placement

Every Taction HL7 integration engineer is screened on four criteria:

Production HL7 v2 experience — at least 3 years of channel and interface development in live healthcare environments
HL7 v2 segment-level fluency — MSH, PID, PV1, OBR, OBX, ORC, RXA, common ADT event types, custom Z-segments
Integration engine experience — Mirth Connect / NextGen Connect, Rhapsody, Cloverleaf, Corepoint, or native EHR interfaces
FHIR R4 bridging — HL7 v2 to FHIR transformation patterns, CDA to FHIR, FHIR R4 to HL7 v2 reverse mappings

What a Taction HL7 Engineer Does on Day One

You get a dedicated engineer embedded in your integration team for a minimum 3-month engagement billed monthly at $8K.

Featured

Week One and Two Deliverables

Inventory your existing HL7 v2 interface map including sources, destinations, message types, and event triggers
Document undocumented downstream dependencies and custom Z-segments
Identify interfaces that are failing, throttling, or have orphaned dependencies
Stand up a local integration engine development environment matching your production stack
Wire audit logging that captures interface, message ID, transformation result, and error class per HIPAA §164.312(b)

By week six, that engineer is shipping interface updates, new HL7 v2 integrations, and FHIR R4 bridges through your CI/CD pipeline.

Engagement Models and Pricing for HL7 Integration Engineers

Dedicated HL7 Integration Engineer

$8,000 per engineer per month. Minimum 3-month commitment, month-to-month thereafter. Full-time, dedicated, embedded in your team. Includes BAA, project management, and Taction technical-architect oversight.

HL7 Integration Pod

$24,000 to $48,000 per month for a pod of 3 to 6 engineers, useful for multi-site interface consolidation or large migration projects.

Fixed-Scope HL7 Engagement

For defined scopes such as a multi-interface migration or an integration-engine upgrade, we structure fixed-price engagements. For background and pricing, see the HL7 integration services page and the Mirth Connect integration service.

For a project-based estimate, use the healthcare AI cost calculator or the EHR integration calculator.

HIPAA Compliance Baseline

Every Taction HL7 engagement starts with the same baseline.

BAA executed before any access to PHI-bearing systems

HIPAA Security Rule §164.308, §164.310, and §164.312 controls verified

Audit logging at the interface and message layer

PHI redaction in non-production environments and in error logs

Encryption at rest with AES-256 and in transit with TLS 1.3, including MLLP-over-TLS where supported

When to Hire an HL7 Integration Engineer (and When Not To)

Use a Dedicated HL7 Engineer When

You have an existing HL7 v2 interface portfolio that needs ongoing maintenance and new interface development
You are migrating from one integration engine to another (Rhapsody to Mirth, Cloverleaf to Corepoint, etc.)
You are adding FHIR R4 bridges on top of an HL7 v2 backbone
You are consolidating interfaces during a hospital merger or acquisition
You are integrating a new lab, imaging center, or pharmacy network into a hospital system

Choose a Different Engagement When

Your integration engine is specifically Mirth Connect — hire Mirth Connect engineers instead
You are starting greenfield with FHIR R4 and no legacy HL7 v2 — hire FHIR developers instead
You are building an Epic-specific integration through Bridges — hire Epic integration developers
