Paste an HL7v2 message and click Convert
Supported: ADT · ORU · ORM · VXU · RDE
The HL7v2 to FHIR Converter transforms legacy HL7 version 2 messages into FHIR R4 resources. Paste an ADT, ORU, ORM, or any HL7v2 message and see the corresponding FHIR Patient, Encounter, Observation, DiagnosticReport, or other resources generated instantly.
This is invaluable during migration projects where health systems are transitioning from HL7v2 feeds to FHIR APIs. Use it to understand how v2 fields map to FHIR elements, verify conversion logic, or quickly generate FHIR test data from existing HL7 messages.
FHIR (Fast Healthcare Interoperability Resources) is the modern standard replacing HL7v2 in many contexts. CMS regulations, the 21st Century Cures Act, and TEFCA all push toward FHIR adoption. But most health systems still run thousands of HL7v2 interfaces. Understanding the mapping between v2 and FHIR is essential for any interoperability team.
Need to document exactly how your v2 messages should map to FHIR? Conformance Specs let you define field-level rules for your HL7v2 interfaces, share them with trading partners, and validate messages programmatically.
