Do you build SMART on FHIR apps for EHR launch contexts?

Yes. We implement secure launch, scopes, consent-aligned access, and in-workflow UX for embedded clinical tools.

How do you reduce integration maintenance overhead?

We use reusable connectors, contract tests, and observability-first integration patterns so operations remain predictable as systems evolve.

Which regulations drive healthcare interoperability work?

Three come up on most projects. The information blocking rules (45 CFR Part 171) restrict practices that interfere with access to electronic health information. USCDI, maintained by ASTP/ONC, sets the standard data classes for exchange. And CMS-0057-F requires impacted payers to build FHIR APIs, including a Prior Authorization API, with most compliance dates starting January 1, 2027.

Do you sign a BAA for interoperability work?

Yes. When an integration touches protected health information, Agnotic signs a business associate agreement before any PHI is shared with our team, as the HIPAA Privacy Rule requires (45 CFR 164.502(e)), and we keep PHI out of development and test environments.

Can we start with a fixed-scope first release?

Yes. Most interoperability engagements start with one integration, such as a FHIR read from one EHR or one HL7 v2 feed, built and monitored in production. Later integrations reuse the same connectors and canonical model.

What We Do: Trust Layer

Interoperability

We design and implement production-grade interoperability across FHIR R4, HL7 v2, SMART on FHIR, and CDS Hooks so your platform can exchange data reliably with modern provider ecosystems.

Healthcare interoperability and EHR integration architecture

What is healthcare interoperability?

Healthcare interoperability is the ability of EHRs, labs, payers and patient apps to exchange health data and use it without manual re-entry. Agnotic Technologies builds it for digital health companies, providers and payers: HL7 FHIR APIs, HL7 v2 interfaces, SMART on FHIR apps and CDS Hooks services, with HIPAA safeguards and audit logging designed in.

Standard	When to use	Best fit systems
FHIR R4	Resource-oriented APIs, modern app ecosystems, and scalable longitudinal records.	Patient apps, care management platforms, payer-member apps, and analytics products.
HL7 v2	Event-driven interfaces for ADT, orders, results, and legacy hospital communication.	Hospital systems, lab connectors, imaging workflows, and interface engines.
SMART on FHIR	Embedded applications that need secure launch and context inside EHR workflows.	Clinical tools within Epic, Oracle Health (Cerner), athenahealth, and similar provider ecosystems.
CDS Hooks	Real-time decision support at critical points in clinician workflows.	Order entry support, medication checks, pathway nudges, and in-context suggestions.

Which systems do we connect?

We build reliable connections across the systems that matter most to healthcare products.

EHR and EMR platforms

Epic, Oracle Health (Cerner), athenahealth, and other provider-side record systems.

Labs and diagnostics

Inbound/outbound result pipelines, ordering workflows, and event notifications.

Payers and eligibility

Claims and coverage-linked data exchange for operational and care workflows.

Patient-facing products

Mobile apps, portals, and remote-care experiences synchronized with source systems.

Patterns that keep integrations reliable

Patterns we use to reduce rework and increase reliability in live healthcare ecosystems.

Canonical data model with mapper adapters for each external system
Event-driven ingestion plus idempotent write behavior for resilience
Version-tolerant connectors for changing vendor APIs
Replay-safe queues and dead-letter handling for message recovery

Where do interoperability projects fail?

Critical mistakes that often delay EHR and data exchange initiatives.

One-off connector architecture

Impact: Each new integration becomes slower and more expensive.

Mitigation: Use adapter patterns and canonical models from day one.

Schema drift not managed

Impact: Production breakages when partner systems evolve.

Mitigation: Implement contract checks, version awareness, and rollback-safe releases.

Insufficient observability

Impact: Interface errors are discovered late and are hard to diagnose.

Mitigation: Add transaction-level tracing and alerting across integration paths.

Frequently Asked Questions

Yes. Most healthcare products need both. We design architecture that supports modern APIs while still handling legacy event flows.
