FHIR SDC intersects with payer prior authorization workflows through Da Vinci DTR (Documentation Templates and Rules). Understanding the integration shapes CMS-0057 compliance.
Da Vinci DTR overview
DTR provides Questionnaires that guide providers through PA documentation. Payer publishes DTR Questionnaire; provider fills; QuestionnaireResponse feeds PA submission.
Integration flow
1. Provider initiates order. 2. Da Vinci CRD via CDS Hooks determines PA required. 3. If PA required, DTR Questionnaire loaded. 4. Provider fills; SDC pre-population from clinical data. 5. QuestionnaireResponse extracted to Claim + Observation resources. 6. Da Vinci PAS submits PA request to payer. 7. Payer response returned; PA status tracked.
SDC-specific requirements for DTR
1. Full enableWhen + enableWhenExpression. 2. Calculated expressions for auto-computed fields. 3. Server-side $extract to structured resources. 4. Pre-population from patient clinical data. 5. Multi-language for member-facing.
CMS-0057 compliance
1. Da Vinci PAS profile conformance. 2. Da Vinci CRD hook support. 3. Da Vinci DTR Questionnaire structure. 4. Inferno verification.
Common integration mistakes
1. Custom PA workflow vs. Da Vinci. 2. Manual documentation vs. DTR. 3. Missing pre-population. 4. Client-side calculation. 5. No extract to structured resources.

FHIR SDC in payer prior auth is the FHIR-native path. Sites using Da Vinci DTR + PAS ship CMS-0057-compliant workflows; sites building custom PA processes struggle.
