EHR / EMR Systems
MEDITECH Integration
MEDITECH is a widely deployed EHR across community hospitals and health systems in the US, UK, and internationally, with its modern web-based platform branded Expanse. Integrating with MEDITECH means working with its FHIR APIs and developer tooling (including the Greenfield program) to read and write clinical data. This guide covers how MEDITECH integration works, the setup path, practical use cases, and the compliance posture required when handling patient data.

How MEDITECH integration works
MEDITECH Expanse exposes FHIR-based APIs for clinical data exchange, complemented by traditional HL7 v2 interfaces in many deployments. Apps authenticate and request scoped access, then read and write FHIR resources representing patients, encounters, results, and more. MEDITECH's Greenfield Workspace provides a sandbox and developer documentation for building and testing integrations. As always, the available APIs, resources, and version depend on the specific customer's MEDITECH platform and configuration, so confirming capabilities early is essential.
Developer onboarding and distribution
MEDITECH supports third-party development through its Greenfield program, which offers sandbox access and documentation to build and validate integrations. Going live at a specific site still requires that organisation's involvement to enable and configure the integration. Engineering against MEDITECH's FHIR APIs is usually straightforward; the surrounding steps — partnership, security review, and per-site enablement — are where realistic timelines are set.
Compliance and data handling
MEDITECH integrations process Protected Health Information, so HIPAA (US) and UK GDPR / NHS DSP Toolkit (UK) apply. You will need Business Associate Agreements, encryption in transit and at rest, least-privilege access, audit logging, and careful governance of any patient data flowing into AI services. These controls are both a regulatory requirement and a prerequisite for passing a hospital's security assessment.
How to integrate with MEDITECH
- 1
Access MEDITECH's Greenfield Workspace
Register for Greenfield to get sandbox access, FHIR API documentation, and developer credentials.
- 2
Confirm FHIR capabilities for the deployment
Check which FHIR resources, versions, and interfaces the target MEDITECH (Expanse) site supports.
- 3
Implement authentication and scopes
Build the authorisation flow and request least-privilege scopes for the data and actions your app needs.
- 4
Map and validate clinical data
Map your data model to MEDITECH's FHIR resources and test reads and writes against the sandbox.
- 5
Complete review and per-site enablement
Sign BAAs, pass security review, and coordinate with each organisation to enable the integration in production.
Common use cases
- Documentation and copilot tools surfacing inside MEDITECH Expanse workflows
- Reading results and clinical data for analytics or decision support
- Writing structured data back to the record after clinician review
- Connecting community hospital data into broader population health pipelines
Workflow example
Discharge summary automation
- App accesses the patient's encounter data via MEDITECH's FHIR API.
- Clinical NLP and an LLM draft a structured discharge summary from the notes and results.
- The clinician reviews and edits the draft for accuracy.
- On approval, the summary is written back to the record and shared per the care pathway.
Frequently asked questions
What is MEDITECH Greenfield?
Greenfield is MEDITECH's developer program and workspace, providing sandbox access and documentation for building FHIR-based integrations with the MEDITECH platform before deploying to a live customer site.
Does MEDITECH support FHIR?
Yes. MEDITECH Expanse offers FHIR-based APIs for clinical data exchange, alongside HL7 v2 interfaces common in existing deployments. The exact resources and version depend on the customer's platform.
Is MEDITECH used in the NHS?
MEDITECH is used by healthcare organisations internationally, including in the UK. UK deployments must meet UK GDPR and NHS DSP Toolkit requirements in addition to the technical integration work.
What should we plan for when integrating with older MEDITECH deployments?
Not every site runs Expanse. MEDITECH has a long installed base on earlier platforms such as MAGIC and Client/Server, where modern FHIR endpoints may be limited or absent and integration falls back to HL7 v2 interfaces over an engine. Confirm the customer's actual platform version and available endpoints before you scope the work — assuming Expanse-era FHIR access across every site is the most common estimation error we see on MEDITECH projects.
