EHR & EMR Integration Services

Connect with every major EHR and EMR platform — Epic, Oracle Health, MEDITECH, eClinicalWorks, NextGen, athenahealth, and the Allscripts / Veradigm / Altera lineage. We build HL7 v2 interfaces, FHIR R4 APIs, and custom integrations that keep patient data flowing securely across your organization.

What We Do

EHR Integration Capabilities

From HL7 v2 interface development to FHIR R4 API programs, our EHR integration services cover the full spectrum of healthcare data exchange. Pick a capability to see what the work looks like.

Custom middleware + connectors

When off-the-shelf connectors don't fit

Sometimes the standards-compliant path isn't enough — vendor-specific auth flows, proprietary API wrappers, custom transformation logic, or real-time event streaming. We build the software engineering layer that stitches non-standard systems into your clinical stack.

  • Vendor-specific auth adapters (SAML, OAuth variants, session cookies)
  • Proprietary API wrappers around legacy SOAP + REST endpoints
  • Custom transformation logic (XSLT, JS mappers, event processors)
  • Real-time event streaming (Kafka, EventBridge, Pub/Sub topologies)

FHIR R4 API development

FHIR APIs that pass App Orchard review

We design and build FHIR R4 APIs that connect EHRs to downstream apps, patient portals, and third-party platforms. US Core profile-conformant, tested against full conformance suites, and certified through Epic App Orchard, Oracle Code, and athenahealth Marketplace review pipelines.

  • US Core + USCDI v3 profile conformance out of the gate
  • Epic App Orchard, Oracle Code, athenaone Marketplace certification
  • Bulk FHIR $export + ndjson streaming for population workflows
  • CapabilityStatement + SearchParameter coverage for every resource

HL7 v2 interface development

HL7 v2 interfaces for every clinical workflow

Most EHR integrations still land on HL7 v2 — ADT admit/discharge feeds, ORM orders, ORU results, SIU scheduling, MDM documents. We build production-grade interfaces on Mirth Connect, handle vendor-specific Z-segments, and manage MLLP transport, ACK/NAK retries, and message transformation at scale.

  • ADT, ORM, ORU, SIU, MDM, DFT interfaces with Z-segment coverage
  • MLLP framing, ACK/NAK retry, and low-level error taxonomy
  • Mirth Connect / Open Integration Engine channel development
  • Message validation, transformation, and deduplication pipelines

SMART on FHIR embedded apps

Clinician apps that launch inside the EHR

SMART on FHIR apps launch directly inside Epic Hyperspace, Oracle Health, and other SMART-enabled platforms — giving clinicians embedded access to decision support, patient engagement, or third-party data without leaving their workflow. OAuth + PKCE, launch context, standalone and EHR-launch modes.

  • launch/patient + launch/encounter context handshake
  • OAuth 2.0 + PKCE with Epic, Oracle, Cerner, Meditech
  • Hyperspace-embedded iframe layout + theme alignment
  • MyChart standalone launch for patient-facing variants

Data migration + go-live

Zero-data-loss EHR migrations

EHR migrations require meticulous planning, validation, and cutover execution. We handle legacy extraction, data cleansing, terminology mapping, and parallel testing — then run 24/7 go-live support with interface validation and rapid issue resolution so clinical operations never miss a beat.

  • Legacy extraction (HL7 v2, flat-file, proprietary DB schemas)
  • Terminology mapping (ICD-9→10, LOINC, SNOMED, RxNorm crosswalks)
  • Parallel-run validation with discrepancy reconciliation
  • 24/7 go-live command center with SLA-backed incident response

Post-go-live operations

We run your integrations 24/7

After go-live, we provide continuous monitoring, proactive maintenance, and rapid incident response. Interface health dashboards, error-queue triage, on-call coverage, capacity planning, and SLA-backed uptime so your team can focus on clinical outcomes, not integration firefighting.

  • Interface-level uptime SLAs (99.95% or better on critical feeds)
  • Error-queue management + automated reprocess tooling
  • Capacity planning + interface scaling reviews quarterly
  • 24/7 on-call with PagerDuty / Opsgenie escalation tiers

Integration Paradigms

Three Ways Modern EHRs Talk

Every EHR integration uses one (or more) of three communication paradigms. Each has its own strengths, pitfalls, and tooling. Pick a paradigm to see how we build it.

Message-oriented integration

HL7 v2 async messaging — the workhorse

Nearly every EHR integration lands on HL7 v2 eventually. ADT feeds, ORM orders, ORU results, SIU scheduling, DFT financial — all flowing through MLLP-framed pipe-delimited messages over persistent TCP connections. We engineer the interface engine, ACK/NAK handling, resend logic, and long-tail segment coverage that keeps these feeds alive 24/7.

  • ADT (admit, discharge, transfer) feeds with full Z-segment coverage
  • ORM / ORU bidirectional order + result routing
  • MLLP framing, ACK/NAK retries, and low-level error taxonomy
  • Mirth Connect, Corepoint, Cloverleaf, and Rhapsody engine expertise

API-first integration

FHIR R4 REST — the modern standard

FHIR inverts the integration model: instead of messages pushed to your queue, you make authenticated REST calls and get back JSON resources. Patient, Observation, MedicationRequest, Encounter, Condition — each a first-class URL. We build FHIR clients, FHIR servers, custom operations, Bulk Data exports, and the OAuth / SMART handshakes around them.

  • FHIR R4 client libraries for Epic, Oracle Health, athenahealth, MEDITECH
  • FHIR server implementation on top of your existing clinical data
  • US Core + USCDI v3 conformance for 21st Century Cures compliance
  • Bulk FHIR $export with ndjson streaming for population analytics

Real-time event-driven

Event-driven — pub/sub, webhooks, CDS Hooks

When milliseconds matter — clinical decision support fires at order-sign, a sepsis monitor alerts on a new vital, a registry ingests every discharge — polling doesn't cut it. We design event-driven topologies using FHIR Subscriptions, CDS Hooks, message brokers (Kafka, AWS EventBridge, GCP Pub/Sub), and webhook patterns that wire EHR events to downstream consumers in real time.

  • FHIR Subscription (R5 topic-based) + Subscription criteria
  • CDS Hooks: patient-view, order-select, order-sign, encounter-start
  • Message brokers (Kafka, EventBridge, Pub/Sub) for fan-out + replay
  • Webhook delivery with signed payloads + retry backoff

Patterns We Build

EHR Integration Patterns

The high-leverage EHR integration patterns we deploy in production — operational mechanics that go beyond the conceptual frame, mapped to specific EHR vendors, integration standards, and the certification programs that gate production go-live.

Pattern 1 / 5

Multi-Vendor ADT → Unified MPI

Consolidate ADT^A01/A04/A08 feeds from Epic, Oracle Health, MEDITECH, and ambulatory EHRs into a single master patient index — deterministic + probabilistic matching, identifier reconciliation, and dedupe-safe merges so downstream apps see one patient, not three.
