Interoperability Standards & Patterns
Technical guides for HL7, CDA, and healthcare data exchange standards
Medication Data Exchange
Reference guide to FHIR medication resources — MedicationRequest, MedicationDispense, MedicationAdministration, MedicationStatement — with coding, dosage, and reconciliation patterns.
Prior Authorization Workflow
End-to-end guide to electronic prior authorization using the Da Vinci CRD, DTR, and PAS IGs: what each step does, what provider and payer systems must implement, and CMS-0057-F compliance obligations.
CDex — Clinical Data Exchange
End-to-end reference for the Da Vinci CDex IG: direct query, Task-based, and attachment exchange patterns; use cases for claims adjudication, prior authorization, and audit; Task workflow mechanics; and SMART Backend Services authentication.
Healthcare Data Semantics
Clinical vocabulary reference for integrators: SNOMED CT, LOINC, RxNorm, ICD-10, CPT — what each system is, when to use it, and how to approach semantic mapping.
Healthcare Standards Primer
Practical reference for integrators on HL7 v2, CDA/C-CDA, FHIR, X12, and DICOM — what each standard is, how to recognise it, and when to use which.
Healthcare Interoperability: Landscape and Approach
Overview of healthcare interoperability challenges, standards landscape, integration patterns, and how to choose the right approach for your use case.
Legacy-to-FHIR Mapping
Reference for mapping legacy healthcare data models to FHIR resources, including 1:1, 1:many, and many:1 patterns and documentation expectations.
Patient Identity Matching
Reference guide to deterministic and probabilistic patient matching, MPI architecture, the FHIR $match operation, and deduplication strategy for integrators.
Clinical Data Mapping
Clinical-specific FHIR mapping reference for Observation, Condition, and Procedure resources — coding decisions, category traps, and anti-patterns unique to clinical data.
