FHIR Integration Companies: HL7 FHIR Integration Services and Partners

FHIR integration companies connect your software or data platform to EHRs and other clinical systems using HL7 FHIR APIs, often alongside HL7 v2 and other legacy interfaces. The vendors listed here offer FHIR integration or EHR integration services. Below the listings you will find what a typical engagement includes and how to judge whether a partner can deliver yours.

What FHIR integration companies actually deliver

An integration engagement is mostly about the space between two systems: authentication, data mapping, error handling and the operational work of keeping a connection alive. A competent partner will usually cover:

  • Connection design. Choosing between patient-facing, provider-facing (SMART launch) and backend system access for each data flow, and the OAuth flow that goes with it.
  • EHR onboarding. App registration, scope requests, sandbox testing and coordinating production enablement with each customer site.
  • Mapping and normalization. Translating FHIR resources to and from your internal model, handling terminology (LOINC, SNOMED CT, RxNorm) and site-specific extensions.
  • Hybrid interfaces. Most EHRs still deliver some events (ADT, results, orders) over HL7 v2, so many integrations combine FHIR reads with v2 feeds. See FHIR vs HL7 v2.
  • Monitoring and support after go-live, including handling EHR upgrades.

Our FHIR integration service overview describes the scope in more detail, and the FHIR API integration guide covers the technical patterns.

When to bring in an integration partner

  • You need to connect to more than one EHR and each has its own registration process, scopes and write-back limitations.
  • Your first customer is waiting and you cannot afford to learn EHR onboarding by trial and error.
  • You need write access (creating orders, documents or appointments), which is where EHR-specific constraints and proprietary APIs are most common.
  • Your internal team knows your product well but has not worked with US Core, SMART scopes or HL7 v2 before.

How to evaluate HL7 FHIR integration services

CriterionWhat a good answer looks like
EHR-specific experienceCan describe the registration and production enablement path for your target EHRs, including which data is read-only
Write-back strategyExplains which writes are possible through FHIR and which need proprietary APIs or HL7 v2
Testing approachUses EHR sandboxes plus realistic synthetic data; tests error paths, not only happy paths
SecurityLeast-privilege scopes, secure key storage for backend clients, audit logging, PHI-free logs
OperationsDefined monitoring, alerting and support SLAs; a plan for EHR version upgrades
Ownership of code and mappingsYou own the mappings and configuration, documented well enough for another team to take over
Evaluation checklist for FHIR integration partners

Ask each candidate to walk through one integration they delivered against an EHR you use, including what went wrong. The answer reveals more than a capabilities deck.

Red flags

  • Promising full read and write access to every EHR through FHIR alone. Write coverage varies by EHR and by customer configuration.
  • Timelines that ignore customer-side steps such as security review and production enablement, which you do not control.
  • No plan for handling site-specific differences between two customers on the same EHR.
  • Claiming an official partnership with an EHR vendor that you cannot verify on the EHR vendor’s own site.

Budgeting

Integration cost depends mostly on the number of EHRs, read versus write scope and how much mapping is needed. See FHIR integration cost for the drivers and illustrative ranges.

Frequently asked questions

What does a FHIR integration company do?

It connects your application or data platform to EHRs and other clinical systems using FHIR APIs: registering apps, implementing OAuth and SMART flows, mapping data, handling HL7 v2 where FHIR does not cover a workflow, and supporting the connection after go-live.

How do I identify the top FHIR integration companies for my project?

Start from your target EHRs and required data flows, then shortlist partners who can show delivered work against those EHRs, a clear write-back strategy and a defined support model. This directory does not rank vendors; the evaluation checklist on this page is designed to help you identify the best fit.

Can FHIR replace all of our HL7 v2 interfaces?

Usually not yet. Many EHRs still deliver real-time events and some write workflows via HL7 v2 or proprietary APIs. A good integration partner designs a hybrid architecture and migrates flows to FHIR where support is mature.

How long does a FHIR integration project take?

A read-only integration against one EHR sandbox can be built relatively quickly, but production timelines are often driven by EHR app review and each customer’s security review and enablement. Ask partners to separate build time from approval time in their plans.
