Healthcare Interoperability Solutions
Connect healthcare data. Build interoperable healthcare products.
Peerbits helps healthcare and HealthTech companies connect EHRs, applications, and healthcare data using FHIR, HL7, APIs, SMART on FHIR, and modern interoperability architecture — engineered into the product, not added on after launch.
The Problem
Healthcare data is fragmented — and it slows the product down.
Whether you're a hospital network or a HealthTech product team, the same underlying problem shows up: systems that were never designed to talk to each other, and integrations that get harder to maintain every year.
Fragmented systems
Patient and clinical data sits across EHRs, labs, imaging systems, and payers — never available in one place at the right time.
Disconnected EHRs
Every EHR vendor exposes data differently, which turns each new connection into a custom engineering problem.
Legacy HL7 interfaces
Decades-old HL7 v2 interfaces remain embedded in lab, ADT, and pharmacy workflows, and they're brittle to change.
Inconsistent data models
The same clinical concept is often represented differently across systems, which breaks downstream logic and reporting.
Point-to-point integrations
Custom, one-off connections between systems multiply maintenance cost and make every new integration slower than the last.
Manual workflows
Fax machines, PDF attachments, and manual re-entry introduce delay, transcription error, and compliance risk.
Definition
What healthcare interoperability means
Healthcare interoperability is the ability of different health IT systems, devices, and applications to access, exchange, and cooperatively use clinical and administrative data — in a structured, real-time format, rather than as PDFs, faxes, or manual re-entry.
Peerbits provides healthcare interoperability engineering services covering FHIR, HL7, EHR integration, SMART on FHIR, healthcare APIs, and healthcare data mapping — as a foundation for both healthcare organizations connecting existing systems and HealthTech companies building interoperability into a new product.

Use Cases
Healthcare interoperability use cases
Real integration problems, engineered with production-grade architecture.
Hospital Network Integration
Connect multiple hospitals and clinics across a health system into a unified patient record, so clinicians at any location can access complete longitudinal history.
EHR → Healthcare SaaS
Connect a mobile or web health application directly with an EHR using SMART on FHIR — read patient data, write back outcomes, and trigger CDS Hooks through standardized APIs.
HL7 → FHIR Modernization
Build a FHIR-facing API layer over legacy HL7 v2 systems, so modern applications can consume decades-old lab, ADT, and pharmacy data through standardized APIs.
Payer ↔ Provider Interoperability
Connect prior authorization, eligibility verification, and claims workflows between providers and payers using healthcare APIs and Da Vinci implementation guides.
Device / RPM → Healthcare Platform
Ingest continuous streams from wearables and home monitoring devices, normalize the readings, and push clinically relevant data into the patient record.
Multi-EHR Product Integration
Engineer a single integration layer that can connect a healthcare product to multiple EHR vendors, rather than building a one-off connector for each.
Product Engineering Bridge
Build interoperability into your healthcare product
Interoperability works best as part of the product architecture from the start — not as an integration added after the product is already built.
When interoperability is architected in from day one, EHR connectivity, FHIR APIs, and data mapping become part of how the product is designed to work — which is easier to maintain and easier to extend than integrations bolted on afterward.

Data + AI
Make healthcare data usable for AI
AI healthcare products depend on accessible, structured, and appropriately governed data. Interoperability is a necessary foundation for that — but not a complete solution on its own.
This is the same engineering discipline behind Peerbits' AI Medical Scribe and AI Medical Coding products, both of which depend on clean, structured healthcare data flowing through the underlying integration layer.

Modernization
Modernize legacy healthcare integrations
For organizations running HL7-heavy systems, point-to-point integrations, brittle interfaces, or duplicated integration logic across proprietary formats. The goal is to protect existing clinical workflow knowledge while replacing brittle connections with a maintainable interoperability layer.

Frequently asked questions
Healthcare interoperability is the ability of different health IT systems, devices, and applications to access, exchange, and cooperatively use clinical and administrative data — in a structured, real-time format, rather than as PDFs, faxes, or manual re-entry.
FHIR (Fast Healthcare Interoperability Resources) is the modern REST API standard for healthcare data exchange, using JSON or XML structured resources. It's significantly easier to build against than legacy HL7 v2 messaging, and it's the standard most current EHR vendors expose FHIR R4 APIs against.
Integration timelines depend on the systems involved, data scope, workflows, authentication requirements, testing, and deployment complexity. There is no fixed universal timeline — Peerbits scopes each integration individually based on these factors.
HL7 v2 is a pipe-delimited messaging format still widely used in labs, ADT feeds, and pharmacy systems. FHIR is a modern REST API standard using structured JSON or XML resources. Many healthcare environments run both, and it's common to build a FHIR-facing API layer over an HL7 v2 system so modern applications can consume legacy data through standardized APIs.
Peerbits engineers EHR connectivity using each vendor's exposed FHIR R4 APIs and SMART on FHIR authentication patterns. Exact scope and feasibility depend on the specific EHR, the data being exchanged, and the vendor's access requirements, which Peerbits assesses per engagement.
Yes. Mapping and transforming data between source formats — HL7 v2, proprietary EHR formats, X12 — and standardized FHIR resources is core to Peerbits' interoperability engineering work.
Interoperability is a necessary foundation for AI-ready healthcare data, but it isn't sufficient on its own — data quality, architecture, governance, and workflow context matter just as much. Peerbits addresses all of these together rather than treating interoperability as a complete solution to AI data readiness.
