Resources & Insights
Expert guidance on healthcare data integration - HIPAA X12, FHIR R4, HL7, and regulatory compliance from the team at Redix.
Architecture & Strategy
System design decisions for healthcare data infrastructureWhy 278 PAS? The Question Nobody Is Asking
The X12 278 has among the lowest adoption of any HIPAA transaction. CMS responded with FHIR-based Prior Auth APIs - but the legal and architectural implications of running two parallel standards are rarely discussed.
FHIR Is an Interface Contract - Not an Operational Core
Why binding internal prior authorization logic to FHIR creates long-term architectural fragility, and how a canonical operational model reduces risk as standards evolve.
Compliance & Regulatory
CMS mandates, HIPAA requirements, and deadline guidanceFHIR Provenance: The Compliance Audit Trail for CMS-0057-F
CMS-0057-F is about traceability, not just APIs. What FHIR Provenance is, why prior authorization needs an audit trail, and how Redix emits it.

Which Da Vinci PAS version should you build and validate against? How PAS 2.0.1, 2.1.0, and 2.2.1 affect X12 278 to FHIR PAS work.
What Medicare Advantage Plans Need to Know About Prior Authorization APIs
MA plans are directly in scope for CMS-0057-F. The dual-stack path: a FHIR API out front, X12 278 inside, and a conversion layer between.

Use Cases & ROI
Real-world implementation strategiesFrom Months to Minutes: Accelerating EDI Integration
Stop building healthcare data parsers. Shift from months of EDI development to minutes of API integration. Focus engineering talent on proprietary value.
837 and 835 Audit Archives: Why PDF Conversion Alone Is Not Enough
Auditors ask for specific claim and remittance images years later. A converter renders a file; an archive lets you find it, show what it came from, and hand over a verifiable package.
