Every healthcare format, translated in days, not quarters.
Health1st translates HL7 v2, FHIR, C-CDA, X12 and NCPDP in both directions. AI agents draft the mappings, normalize the codes and validate against US Core, so your team reviews instead of hand-building. Your HL7 backlog is measured in months. Ours in days.
- HL7 v2.x ↔ FHIR R4/R4B/R5 at the core: round-trip fidelity
- US Core, Da Vinci & IPS conformance, with exportable reports
- Built for CMS-0057-F: four FHIR APIs due January 1, 2027
- Deploy in cloud, VPC or on-prem, and you control the data

Must expose FHIR. Still runs HL7 v2.
That single gap, created by the Cures Act and sharpened by CMS-0057-F, is where interface teams drown. Every point-to-point interface is hand-built, brittle, and measured in weeks.
A backlog measured in months
Each new interface is a manual mapping-and-testing project. Scarce, expensive HL7 analysts become the bottleneck for every integration.
A hard 2027 deadline
CMS-0057-F forces impacted payers to stand up four FHIR APIs by January 1, 2027. As of October 2025, roughly 43% of payers had not started.
Incumbent engines cost a fortune
Legacy engines run from six figures to $10M+/year at mega scale, and stay consultant-heavy long after the contract is signed.
Clinical errors are unacceptable
A mis-mapped diagnosis or dose is a patient-safety event. Speed can't come at the cost of accuracy or auditability.
Ingest → AI-map → validate → deliver
One pipeline runs every transformation. AI agents draft and normalize; your team reviews; the engine validates and delivers with full audit.
- 1
Ingest
Accept any source: HL7 v2 over MLLP, FHIR REST, C-CDA XML, X12 EDI, NCPDP, flat files or a custom API. Real-time, batch or streaming, with guaranteed delivery and replay.
- 2
AI-map
The Mapping and Terminology agents draft field- and segment-level mappings, normalize codes (ICD-10, SNOMED, LOINC, RxNorm↔NDC), and explain every decision in plain English for human review.
- 3
Validate
The Validation agent checks output against US Core, Da Vinci and IPS profiles (cardinality, bindings, must-support) and produces the conformance report procurement and auditors ask for.
- 4
Deliver
The Transformation and Orchestration agents serialize, route and reliably deliver the result (a FHIR bundle, an X12 278, an NCPDP SCRIPT message) with round-trip fidelity and full audit.

The protocol & format matrix
Bidirectional support across the clinical, payer/administrative and pharmacy domains, plus the terminology systems that make a mapping actually correct.

Terminology & code systems (translation + normalization)
Crosswalks such as ICD-10 E11.9 ↔ SNOMED, and RxNorm ↔ NDC (e.g. ATORVASTATIN CALCIUM, NDC 59651-608) are handled by the Terminology agent with a confidence score on every match.
Engine capability, without the consulting tax
Everything a legacy engine does, plus AI mapping, conformance reporting and deployment flexibility that API networks and hyperscaler stores don't give you.
Bidirectional by design
Every meaningful pairing runs both directions. v2→FHIR powers APIs and patient access; FHIR→v2 keeps feeding the systems that still speak HL7 v2.
AI mapping, human review
Agents propose mappings; your team approves them. Every mapping is versioned with diff and one-click rollback, and every field carries a plain-English explanation.
Conformance you can hand to procurement
Validation against US Core, Da Vinci and IPS profiles produces exportable conformance reports. That is the artifact buyers require before they integrate.
Real-time, batch & streaming
MLLP feeds, REST APIs, nightly batch and Bulk FHIR $export all run on the same engine, with guaranteed delivery, retry and replay.
Deploy where your data lives
Cloud, single-tenant VPC or on-prem. Control data residency and keep PHI inside your boundary. That is a control API networks can't offer.
First interface in days
The Onboarding agent learns a partner's format from sample messages and bootstraps the first interfaces, collapsing weeks-long builds into days.
Twelve specialists, one orchestrator
Each agent owns a domain (mapping, terminology, validation, prior-auth, pharmacy and more) and operates with human-in-the-loop review and full audit.
Agent codenames are working names pending trademark & domain clearance. Functional names describe what each agent does.
Explore the platform
Each surface has its own deep dive, from the core translation engine to prior authorization, pharmacy and security.
