HL7 & FHIR Interoperable Practice Management Software
Unlimited Integration supports both HL7v2 and FHIR R4 standards, giving specialty practices certified, bi-directional connectivity to the EHRs, clearinghouses, and payer networks they already use, demographics, scheduling, charges, and clinical documentation move automatically, without manual re-entry.
What changes with HL7 & FHIR Interoperability
Without it
Legacy HL7-only connections
Some platforms only support older HL7v2 interfaces, limiting compatibility with newer FHIR-based EHR modules.
One-way data flow
Interfaces that only push data in one direction leave billing systems working from stale clinical context.
Custom mapping projects
Non-standard interfaces often require costly, one-off mapping work for every new connection.
With Unlimited Systems
HL7v2 and FHIR R4 support
Unlimited Integration speaks both HL7v2 for established EHR interfaces and FHIR R4 for modern resource-based exchange.
Bi-directional sync
Demographics, scheduling, charges, and clinical documentation flow both ways, keeping billing and clinical systems aligned.
Standards-based connectivity
Because connections are built on HL7 and FHIR standards, new EHR and clearinghouse connections don't require bespoke mapping projects.
What you get on day one
HL7v2 ADT, SIU, DFT interfaces
Registration, scheduling, and charge transactions exchange via standard HL7v2 message types.
FHIR R4 resource exchange
Patient, Encounter, Coverage, and Claim FHIR R4 resources support modern EHR integrations.
EDI routing via Unlimited Clearinghouse
270/271 eligibility and 837/835 claims and remittance route through Unlimited Clearinghouse alongside HL7/FHIR clinical interfaces.
Audited, encrypted transport
All HL7 and FHIR connections run through SOC 2-audited, encrypted infrastructure with full transaction logging.
