DTR
Da Vinci Documentation Templates and Rules. DTR uses FHIR Questionnaire (with FHIRPath-driven prefill and skip logic) to collect the clinical documentation a payer needs to decide a prior authorization.
Payerbox supports two implementation paths.
| Page | Use case |
|---|---|
| Aidbox as Questionnaire storage | Server-side packaging of Questionnaire and ValueSet bundles for client-side rendering |
| DTR SMART App | EHR-launched SMART on FHIR app that renders the questionnaire and prefills it client-side |
Prefill runs on the client (the DTR SMART app or another DTR-aware client), not on Aidbox: the questionnaire's FHIRPath initialExpressions are evaluated client-side (SDC $populate), with no CQL engine. Aidbox stores the Questionnaire and ValueSet resources; $questionnaire-package returns a Bundle of the Questionnaire with its expanded ValueSets.
Both paths produce a QuestionnaireResponse that becomes input to PAS.
