FHIR Integration Services

Corsac Bridges Your Disparate Healthcare Systems with FHIR Solutions

Fragmented healthcare data makes it difficult to obtain complete and correct information in real time, resulting in increased integration costs and delayed clinical decisions.

Corsac integrates FHIR into your workflow, enabling smooth data interchange between EHR, payer, lab, and clinical systems.

Signs Your Business Needs a FHIR Integration Review

icon

Your systems store patient data in HL7 v2 or CDA formats that modern platforms can’t read.

icon

Your team has to build a separate integration from scratch every time a new system is added.

icon

You can’t access complete patient records without switching between systems.

icon

You are struggling to meet mandatory baseline requirements like US Core 6.1

You are considering FHIR consulting to stop losing revenue due to errors caused by manual data input

FHIR Integration Challenges We Solve

Healthcare organizations turn to FHIR consulting services when every new system or payer requirement adds another custom interface to maintain.

result

Data silos leave no clear system of record

When the EHR, LIS, and billing disagree on an allergy, nobody knows which is right, as each team trusts its own copy. We set the source of truth per data domain before exposing it via FHIR.

HL7 v2 and CDA formats vary by vendor and site

HL7 v2 feeds come with custom Z-segments, repurposed fields, and local codes, while CDA buries discrete data in narrative. Our FHIR implementation profiles each feed first, so mappings match what systems send.

Patient records are split across IDs and documents

Clinicians see partial medication histories when one patient carries different IDs across EHR, lab, and payer systems. We match identities and turn CDA summaries into queryable FHIR resources.

Point-to-point integrations multiply with every new system

Ten directly wired systems can need up to 45 interfaces, and one vendor upgrade breaks several at once, eating your release cycle. With a single FHIR layer, every new system connects once.

Regulatory FHIR requirements change faster than custom builds

US Core keeps releasing new versions, and CMS-0057-F obliges payers to run FHIR APIs, so a one-time build drifts out of FHIR compliance. We version profiles and rerun conformance tests in your CI/CD.

Undocumented interface rules block every change

When the one engineer who knows your interface engine scripts is away, nobody risks changing a feed. We extract and document that logic and keep FHIR mappings in your Git as versioned code.

Delivering Connected Healthcare Systems: Our Case Studies

With over 18 years of healthcare modernization experience, Corsac helps organizations connect fragmented systems through FHIR. We convert HL7, CDA, and proprietary data into structured FHIR resources, build compliant APIs, and validate integrations before go-live to ensure secure, reliable data exchange across EHR, payer, lab, and clinical systems.

Core FHIR Implementation Services for Healthcare Organizations

As an expert FHIR vendor, Corsac converts legacy formats, builds compliant APIs, and connects clinical and operational systems without replacing what’s already working. We embed compliance requirements into the design from the start.

modernization-solution

FHIR Readiness Assessment & Integration Strategy

Our experts perform a thorough analysis of the current system, review the data flows, compliance requirements, and integration priorities, and build a prioritized roadmap that sequences integration work by clinical and regulatory impact.

FHIR API Development & Integration

We implement secure, standards-compliant FHIR APIs that enable seamless data exchange between healthcare applications, EHRs, payer systems, patient portals, and third-party platforms.

Legacy Healthcare System Modernization

Corsac extends the value of existing healthcare infrastructure by connecting legacy HL7, CDA, and proprietary systems to modern FHIR-based environments without costly system rewrites and operational disruption.

FHIR Data Mapping & Transformation

We remove data silos and transform clinical and administrative data into structured FHIR resources with accurate mapping and validation, so data is consistent and usable across diverse healthcare systems and workflows.

EHR, EMR & Health Information Exchange Integration

Corsac links EHR and EMR platforms to payer networks, health information exchanges, and third-party clinical tools, enabling teams to access entire patient data across systems without repeat entry or manual data requests.

Patient Identity Matching & Record Reconciliation

We add the MPI/EMPI layer that resolves patients across EHR, lab, payer, and HIE systems, so unified records resolve not one patient and do not create duplicates.

US Core Conformance & Profiling

We implement the required US Core profile, publish a Capability Statement and validate the system’s compliance in Inferno before go-live.

FHIR Testing, Compliance & Ongoing Support

Our team validates every integration against FHIR conformance requirements and runs end-to-end testing before anything goes live. After deployment, we deliver complete documentation so your developers can manage the system independently.

FHIR Integration with Legacy Healthcare Systems That Stay in Production

Your HL7 v2 interfaces, CDA archives, and custom databases hold years of clinical history and run daily operations. Replacing them for FHIR APIs puts both at risk. Our FHIR consulting services keep them as the system of record under a validated FHIR layer and bring you to FHIR compliance domain by domain.

HL7 v2 message streams become current FHIR resources

ADT, ORU, and ORM messages report events, while FHIR clients expect the current state of a patient, encounter, order, or result. We map each message to FHIR R4 and apply it to that state, handling out-of-order updates, patient merges, and site-specific segments. Your interfaces keep sending unchanged.

CDA archives turn into one reconciled clinical record

Years of CCDs repeat the same allergies and medications with conflicting status, and one-by-one conversion floods the FHIR server with duplicates. We map C-CDA templates to US Core profiles, merge repeated entries, route conflicts to clinical review, and keep each source as a DocumentReference.

Proprietary databases get a FHIR facade over their schema

Clinical and billing apps on Delphi or COBOL with custom SQL schemas follow no healthcare standard. Here, FHIR implementation means a facade that translates FHIR queries into the source schema, reading a replica if live queries would slow your staff. Application code stays untouched.

Local codes map to the terminologies FHIR consumers expect

Legacy systems code lab tests, diagnoses, and drugs with internal lists, while payers and FHIR apps expect LOINC, SNOMED CT, ICD-10-CM, and RxNorm. We build ConceptMaps, flag unmapped codes before go-live, and version every mapping, so each change to clinical meaning is reviewed.

Legacy systems stay the source of truth while FHIR runs on top

We pick a pattern per domain: a live facade for current data, a synced FHIR repository for Bulk Data export and heavy search, or a hybrid. FHIR writes go through the same legacy business rules and validation clinicians rely on. Replacement stays optional, module by module.

    Frequently Asked Questions

    FHIR is a modern standard that enables healthcare systems to securely connect, share, and exchange data across platforms. Better patient data exchange improves care coordination and clinical efficiency, thus allowing healthcare organizations to deliver better care to patients.

    No, FHIR integration runs in phases with the old and updated systems running in parallel until the integration is complete. We build and test the integration layer on top. We embed an automated rollback if the error rate surpasses the undesired threshold before any mistakes and inconsistencies reach the end user.

    FHIR readiness assessment is the first step of our FHIR consulting services aimed at a clear evaluation of your current system and its technical readiness for further updates. During this stage, Corsac evaluates data structures and integration capabilities to identify gaps and define a clear, low-risk roadmap for adopting FHIR.

    No. FHIR integration works on top of your existing systems. Corsac converts your current data formats and builds compliant APIs without replacing what’s already running. We do not do unnecessary, costly rewrites, keep business logic intact, and preserve the experience your users are accustomed to.

    Corsac provides end-to-end FHIR integration services, requiring selective participation in the validation phase. We document every procedure, provide dashboards, and train your staff to maintain and expand the system without relying on third-party vendors.
