Best FHIR Integration and Development Companies in 2026

A firm can ship a strong SMART on FHIR app for Epic and have never mapped an HL7 v2 feed to FHIR R4. Both jobs get filed under FHIR integration, but past the FHIR R4 data model they share, the work is different.

A SMART on FHIR app connects into the EHR and puts a working tool in front of clinicians. Mapping an HL7 v2 feed is a different kind of work: you take the messages hospital systems already send each other and convert them into FHIR R4 so the data is clean enough to use elsewhere.

So when you evaluate an integration partner, a general claim of FHIR experience is the one line both kinds of firm can give you. What tells you more is the specific work each has delivered, and for whom. We built this list on that.

Five qualify on their public delivery records: MEV, Empeek, CapMinds, Telliant, and Binariks.

We scoped the list to core FHIR integration and implementation services and healthcare interoperability work: SMART on FHIR apps, HL7-to-FHIR migration, CMS payer and patient-access APIs, and device-to-EHR exchange. For broader enterprise data governance and master data management, read our breakdown of the top healthcare data management service providers.

Disclosure: MEV publishes this analysis and is one of the five, assessed on the same evidence bar as every other vendor.

The 5 Best FHIR Integration Companies at a Glance

How We Chose These FHIR Integration Companies

We started with a wide pool of software firms that offer FHIR, HL7, and EHR integration services. Then we cut it to the companies that could show the work.

To qualify, a firm had to offer FHIR and EHR integration and back it with at least one published build we could open and read, whether that FHIR work stands as its own service or sits inside a broader software practice.

FHIR work carries a practical limit on evidence. Most integration projects sit under NDAs, so the end client is often anonymized even in a detailed case study. We accepted a published build that describes the standards and scope in technical detail even where the client name is withheld, and we noted where a firm could name a client or a metric.

The 5 Best FHIR Integration Companies, Reviewed

MEV

MEV is a healthcare software engineering firm that builds full-stack digital health applications and custom healthcare data architectures. MEV also takes on the underlying infrastructure: deploying, hardening, and scaling self-hosted FHIR backends for high-throughput healthcare environments.

For a commercial US specialty patient support hub running on Azure, MEV architected and deployed a self-hosted HAPI FHIR R4 engine. To solve multi-stakeholder security challenges across patients, providers, and care teams, the team engineered a custom SMART on FHIR v2 authorization layer. It bridges relation-based access control (ReBAC) with HAPI’s native SearchNarrowingInterceptor, strictly confining record access to the operational boundary where active HIPAA consents and dynamic patient CareTeam assignments overlap.

MEV also engineers through the severe query-amplification and latency bottlenecks common to distributed FHIR implementations:

Query consolidation: Collapsed FHIR read amplification on patient insurance coverages from 171 individual reads to 24 batched requests, reducing warm cache response times from ~39 seconds down to ~0.9 seconds.

Asynchronous audit logging: Re-architected FHIR audit logging out of the synchronous HTTP request thread into an Azure Service Bus pipeline, eliminating an initial 200x query slowdown on patient searches.

Terminology tuning: Re-indexed ICD-10-CM clinical terminology ValueSets, shrinking payload transfers from 8.4 MB down to ~500 bytes.

Best for: Digital health scale-ups and healthcare enterprises needing custom HAPI FHIR deployments, multi-tenant data isolation, and sub-second query performance.

Proof: Technical breakdown of a production specialty patient support hub on HAPI FHIR R4 and Azure, supporting active commercial therapy programs with verified sub-second response times.

Empeek

Empeek is a healthcare software company that builds EHR integrations and SMART on FHIR applications for digital-health platforms.

Empeek has published a detailed Epic integration on FHIR R4. For a US clinic network running multiple sites under one organization, it moved patient demographics and clinical data between sites. The build used OAuth 2.0 with PKCE and reached production in six to eight weeks. 

Best for: Teams connecting an app to Epic or another major EHR through SMART on FHIR, who want a documented authorization and security pattern.

Proof: Epic integration on FHIR R4 and US Core, production connection in six to eight weeks.

CapMinds

CapMinds is a healthcare IT company that specializes in HL7 FHIR Integration and FHIR API development.

CapMinds builds FHIR on the payer and claims side. One of the US third-party administrators hired it to build a FHIR-based claim adjudication engine. The team mapped the client’s custom data to FHIR and wrote custom profiles for the Coverage and Claim resources. The engine formalizes plan rules like deductibles and out-of-pocket maximums, and handles eligibility and pre-authorization. The client is unnamed.

Best for: Payers and TPAs building claims, eligibility, or prior-authorization workflows on FHIR, or modernizing HL7 v2 feeds into FHIR.

Proof: FHIR adjudication engine for a US TPA, with custom Coverage and Claim profiles.

Telliant

Telliant Systems builds FHIR-based EHR and device integration as part of its healthcare software practice.

Telliant has published a connected-care build for a US remote-monitoring provider serving independent hospitals. It uses FHIR-based exchange to collect clinical data from multiple EHRs and bring it into the monitoring platform. The same build integrates connected devices, including a digital inhaler that captures inhalation activity. 

Best for: Remote patient monitoring and connected-device products that need device and EHR data working together over FHIR.

Proof: Connected-care build with FHIR-based EHR integration and device capture, including a digital inhaler.

Binariks

Binariks is a software engineering company that builds FHIR-based healthcare interoperability into digital-health products for regulated US markets.

Binariks builds FHIR into digital-health products headed for the US market. On a healthcare referral platform, it delivered FHIR integration across multiple EHR providers, with ONC-aligned compliance and more than 1.7 million searchable provider profiles. For a risk-detection app for elderly patients, the team laid out a FHIR integration plan to ready the product for US hospital systems and market entry. 

Best for: Digital-health product teams that need FHIR integration plus a path through US compliance for market entry.

Proof: FHIR e-referral platform with searchable provider profiles and ONC-aligned compliance.

Which FHIR Integration Company Is Right for Your Project?

Here’s how the five map to the most common FHIR jobs.

Whichever way you lean, ask the vendor the same thing: which FHIR version and profiles they used, and which systems sat on each end.

What to Ask Vendors When Evaluating FHIR Integration Partners

Five questions will tell you whether a vendor can do your FHIR work, whether that job is integration or FHIR application development services. Ask each one to point at a build they have already shipped.

1. Which FHIR version and profiles did you use? A partner who has done US EHR work will answer R4 and US Core without pausing. If they only say “FHIR,” ask further about  the version and the profile set.
2. Which systems sat on each end? Epic, Cerner, a custom app, an HL7 v2 feed, a connected device. The named endpoints show whether their work lines up with your integration.
3. Can you show a published build we can open and read? A technical write-up that describes the standards and scope. This is the same bar we used to build this list.
4. How did you handle authorization and consent? SMART on FHIR, OAuth 2.0 with PKCE, and access scoping by consent. Thin FHIR experience usually shows up first in security.
5. Can you name a client or a measurable result? Most FHIR projects sit under NDAs, so an anonymized client is normal. A partner should still point to a metric, like a production timeline or a query that got faster.

Plenty of firms list FHIR services on their site. The questions above turn that into something you can check, down to the FHIR version and a build you can open.

Choosing a FHIR Integration Partner

Each of the five companies mentioned specializes in a different FHIR job, and the closest fit is the one that has already built something like yours.

MEV works the enterprise end, where FHIR and HL7 sit inside a larger data integration. If that’s something you need help with, tell us what you’re connecting and we’ll scope it for you.
