Frequently Asked Questions

InteropSuite supports 30+ HL7 v2.x message types including ADT (A01-A40), ORU (R01, R30, R32), ORM (O01), OML (O21), SIU (S12-S26), MDM (T02, T04, T06), VXU (V04), RDS (O13), RDE (O11), and DFT (P03). A generic fallback handler ensures any HL7 v2.x message can be processed.

Yes. InteropSuite processes all data 100% offline on your infrastructure. No PHI is ever transmitted externally. The solution includes HIPAA-compliant quarantine with AES-256-GCM encryption and complete audit logging.

InteropSuite generates FHIR R4 bundles compliant with US Core 6.1.0 profiles. This includes Patient, Encounter, Condition, Observation, DiagnosticReport, Immunization, MedicationRequest, Provenance, Practitioner, Organization, and Location resources.

Typical HL7 messages convert in under 50ms. Batch processing can handle thousands of messages per minute using parallel workers. The engine is optimized for both real-time API integration and high-volume batch processing.

HL7 v2.x uses pipe-delimited message segments designed for point-to-point interfaces, while FHIR uses modern web standards (JSON/XML, REST APIs) with resource-based data models. Converting HL7 v2 to FHIR enables integration with modern healthcare applications and data analytics platforms.

Yes. HL7 messages typically convert in under 50ms, making real-time conversion practical for interface engines and middleware. The static API (Interop.HL7ToFhirAsync) is designed for high-throughput, low-latency processing.

InteropSuite includes a generic fallback handler that processes any HL7 v2.x message type, extracting standard segments like PID (Patient), PV1 (Encounter), and DG1 (Diagnosis) into FHIR resources. This ensures basic patient and encounter data is always captured, even for uncommon message types.

InteropSuite offers a 14-day free trial with full functionality. This allows you to test HL7 to FHIR conversion with your actual data and validate compliance with US Core 6.1.0 profiles before purchasing.

HL7 ORU^R01 observation results are converted to FHIR DiagnosticReport and Observation resources. OBR segments map to DiagnosticReport, OBX segments map to Observation resources linked via DiagnosticReport.result. All resources conform to US Core lab result profiles.
