Compliance-first delivery
Make your systems speak the same language
Healthcare runs on messages. A patient is admitted (HL7 ADT), a test is ordered (ORM), the result comes back (ORU), a claim goes to the payer (X12 837) and the remittance returns (835). When any of those interfaces is missing or unreliable, staff re-key data, results go missing, claims are denied and clinicians work with an incomplete picture. Every system speaks a slightly different dialect of the same standard, which is why integrations so often stall.
We design, build and operate the interfaces that connect your EHR, laboratory, radiology, pharmacy, billing and payer systems. Each interface starts with the partner’s specification and real sample messages; we build mapping and validation, typically on Mirth Connect or the Open Integration Engine, test with the trading partner, and add monitoring and alerting before go-live. Where newer systems expose APIs, our FHIR interoperability team bridges HL7 v2 and FHIR so old and new can work together. For a plain-English comparison of the two standards, read HL7 vs FHIR.
You end up with documented, monitored interfaces, a message trail that supports HIPAA audit requirements, and a team to call when a partner changes their feed. If you would like the whole interface estate watched and supported around the clock, see our interface engine support service.

- HIPAA-aligned, encrypted and audited message delivery
What's Included
Everything you need, delivered by a senior, security-first team.
HL7 v2 Interfaces
Inbound and outbound feeds for admissions, orders, results, scheduling and charges.
FHIR APIs
FHIR R4 resources and APIs, plus mapping between HL7 v2, CCDA and FHIR.
X12 EDI
Claims, remittance, eligibility and enrolment transactions with clearinghouses and payers.
EHR Integration
Interfaces to Epic, Oracle Health (Cerner), athenahealth, OpenEMR and others.
Lab & Device Feeds
LIS, RIS/PACS and medical-device interfaces with validation and acknowledgements.
Monitoring & Audit
Message tracking, error queues, alerting and audit logs for every interface.
Healthcare data integration across every standard
Interoperability is the difference between clinicians having the full picture and staff chasing missing results by phone and fax. We build and operate the interfaces that connect clinical and administrative systems — accurately, securely and with an audit trail for every message — using the standards each trading partner actually requires.
Standards and transactions we handle
- HL7 v2 — ADT (admissions, discharges, transfers), ORM/OMG (orders), ORU (results), SIU (scheduling), MDM (documents) and DFT (charges).
- FHIR R4 — RESTful APIs, SMART on FHIR apps and HL7 v2 ↔ FHIR bridging; see FHIR interoperability services.
- X12 EDI — 837 claims, 835 remittance advice, 270/271 eligibility, 276/277 claim status and 834 enrolment for payer exchange.
- C-CDA — clinical document generation, validation and exchange, including with Health Information Exchanges.
HL7 v2 vs FHIR vs X12 at a glance
| Criteria | HL7 v2 | FHIR R4 | X12 EDI |
|---|---|---|---|
| Purpose | Clinical and operational events inside and between providers | API access to clinical data for apps and partners | Administrative and financial transactions with payers |
| Format | Pipe-delimited segments | JSON/XML resources over REST | Delimited segments in envelopes |
| Transport | MLLP over TCP, often via VPN | HTTPS with OAuth 2.0 | SFTP, AS2 or clearinghouse APIs |
| Typical use | Lab results, ADT feeds, orders | Patient apps, payer and Cures Act APIs | Claims, remittances, eligibility |

Systems we connect
EHRs (Epic, Oracle Health / Cerner, athenahealth, eClinicalWorks, OpenEMR), laboratory (LIS) and radiology (RIS/PACS) systems, pharmacy and e-prescribing, medical devices, clearinghouses and payer gateways — over MLLP/TCP, HTTPS, SFTP and FHIR APIs, all encrypted in transit.
How an integration project runs
- Specification review — partner specs, sample messages, code sets and transport requirements.
- Mapping — field-level mapping documents, terminology translation (LOINC, SNOMED CT, ICD-10, CPT) and agreed handling of edge cases.
- Build — channels in an integration engine, typically Mirth Connect / Open Integration Engine, with validation, filtering, retries and error queues.
- Testing — unit tests with sample messages, end-to-end testing with the partner and volume testing.
- Go-live and support — monitoring, alerting and reprocessing procedures, optionally under our interface engine support service.
Common integration pitfalls
- Assuming “HL7 v2.5.1” means two systems will agree — every implementation has local variations, Z-segments and optional fields.
- Mismatched patient identifiers creating duplicate or merged records.
- Silent failures: messages rejected downstream with nobody alerted.
- Unencrypted MLLP connections over the internet.
- No reprocessing plan when a partner system is down.
Reliable and HIPAA-aligned by design
Every interface is built with validation, error handling, message tracking and alerting so problems surface immediately and nothing is silently dropped. Infrastructure follows the practices in Building HIPAA-Aligned Workloads on AWS, and we document the controls for your HIPAA compliance programme.
How We Deliver an Interface

Test
Unit and end-to-end testing with the trading partner, including error scenarios.
Go Live & Support
Cutover with monitoring and alerting, documentation and ongoing support.
Frequently Asked Questions
It is the practice of connecting clinical and administrative systems so they exchange data reliably — for example sending lab results from a LIS into an EHR, or claims from a practice to a payer. It uses standards such as HL7 v2, FHIR and X12 EDI, usually via an integration engine.
HL7 (v2 and FHIR) carries clinical and operational data such as admissions, orders and results. X12 EDI carries administrative and financial transactions between providers and payers, such as claims (837), remittances (835) and eligibility (270/271). Many organisations need both.
EHRs including Epic, Oracle Health (Cerner), athenahealth, eClinicalWorks and OpenEMR, plus lab, radiology, pharmacy, billing, clearinghouse and payer systems and medical devices — typically through Mirth Connect or the Open Integration Engine.
A single, well-specified interface such as a lab results feed can often be built and tested within a few weeks; the overall timeline depends mainly on partner specifications and testing availability. Programmes with many interfaces are planned in phases.
Individual interfaces are usually fixed-price once the specifications are reviewed. Ongoing monitoring and support is a monthly retainer with defined response times.
We build interfaces with encryption in transit, access controls, audit logging and secure HIPAA-aligned infrastructure, sign a Business Associate Agreement where required, and document the controls for your compliance programme.
