Focused HL7 interoperability

Clinical interoperability, with clear boundaries.

Ingest C-CDA R2.1 / CCD documents, FHIR R4 Bundle XML, Bulk Data NDJSON, and HL7 v2.x messages (over HTTP or MLLP). Emit clean FHIR R4, push to any FHIR server, fire R4 Subscriptions, host CDS Hooks services, run Patient $match, and connect EHRs via SMART on FHIR + Bulk Data $export. Throughput: ~170 CCDs/sec on a single instance.

MLLP transport TCP listener

v2 over MLLP on configurable port (default 2575). Auto-ACK; webhook on receipt.

SMART on FHIR App Launch

Authorization-code flow · launch & exchange endpoints.

FHIR Bulk Data $export

Async kick-off + polling; preview NDJSON resources from each output file.

FHIR R4 Subscriptions rest-hook

Register criteria (e.g. Observation?code=…); HMAC-signed callbacks fire on every match.

CDS Hooks 2 services

patient-view summary cards + medication-prescribe allergy/duplicate-therapy check.

IHE PDQm · Patient $match MPI

Weighted name + DOB + identifier scoring with FHIR match-grade extension.

Terminology 5 systems

LOINC · SNOMED CT · RxNorm · CVX · ICD-10. Pluggable external TX server.

Webhooks HMAC · retries

SHA-256 signed deliveries with exponential back-off (5 attempts).

Ops & metering Prometheus

JSON logs, Sentry hook, Stripe meter events, p50/p95/p99 latency at /metrics.

Intentionally out of scope: HL7 v3 messaging (PRPA/PIX/PDQ — almost no production usage; replaced by FHIR), DICOM imaging, IHE XDS.b SOAP, X12 270/271/837 payer EDI.
