EHR Integration Services

EHR integration connects a third-party healthcare application to an existing electronic health record system so patient data, such as demographics, lab results, medications, and encounters, flows between them automatically, without manual re-entry. The connection runs on HL7 FHIR R4, SMART on FHIR, HL7 v2, or the vendor's own APIs, depending on the EHR vendor and the data involved.

In practice, people use the terms interchangeably. EMR refers to the electronic medical records within a single practice or organization, while EHR refers to a record designed to be shared across organizations. Vendors and buyers use both labels for the same integration work, and the technical standards are identical.

Read-only FHIR integrations with modern EHRs such as Epic or Oracle Health typically take 6 to 14 weeks from sandbox setup to production launch. Bidirectional write-back integrations take 4 to 12 months, because each health system runs its own clinical and security review before activation, and the timeline grows with the number of sites.

Most EHR integration projects range from $30,000 to $150,000 and up. A read-only connection to a single EHR typically costs $30,000 to $55,000. Bidirectional write-back with one major vendor runs $50,000 to $100,000, and an interoperability layer across multiple EHR systems and sites starts around $95,000. Cost is driven mainly by whether you need write-back, how many EHR systems and sites are in scope, and how many data types you need. Ranges are based on Orangesoft's delivery experience, so contact us for a project-specific estimate.

SMART on FHIR (Substitutable Medical Applications, Reusable Technologies on FHIR) is an open standard that lets third-party applications access EHR data securely, using OAuth 2.0 for authorization and HL7 FHIR for data exchange. Apps can launch inside the EHR with patient context, run standalone, or connect as backend services. Certified US EHRs, including Epic, Oracle Health, and athenahealth, must support it.

HL7 FHIR (Fast Healthcare Interoperability Resources) is a REST API-based standard for exchanging healthcare data, published by HL7 International. FHIR R4 is the version currently required for US certified EHR systems and is the default path for new EHR integrations.

HL7 v2 is a message-based standard used since the late 1980s and still carries most real-time clinical feeds, particularly ADT (admission, discharge, and transfer) notifications and lab result delivery. HL7 FHIR R4 is a modern REST API-based standard built for internet-scale exchange. Most new integrations use FHIR, while established hospital systems and high-volume lab interfaces often still run on HL7 v2.

EHR interoperability is the ability of different electronic health record systems to exchange patient data and use it once received, without manual reformatting. It depends on shared standards for data exchange (FHIR, HL7 v2), document structure (C-CDA), and clinical terminology (SNOMED CT, LOINC, RxNorm).

An interface engine is middleware that receives, transforms, and routes clinical messages between healthcare systems, most commonly HL7 v2 traffic inside a hospital. Mirth Connect, Rhapsody, and InterSystems Health Connect are among the most widely used. An interface engine is worth the infrastructure cost when you are connecting many systems; a direct API connection is usually better for a single integration.

In most cases, yes. When you exchange data with an EHR on behalf of a provider or health plan, you act as a business associate, and HIPAA's Privacy, Security, and Breach Notification Rules apply. That means a signed Business Associate Agreement, access controls, audit logging, and encryption in transit and at rest, which HHS treats as expected practice and has proposed to make mandatory. Consumer apps that patients connect on their own through patient access APIs usually fall outside HIPAA and instead fall under the FTC Health Breach Notification Rule.

Yes, we sign Business Associate Agreements for HIPAA-regulated data. A BAA is required whenever a vendor handles protected health information on behalf of a covered entity or another business associate, which applies to most EHR integrations.
