Da Vinci Prior Authorization Support (PAS) FHIR IG
2.2.0-ballot - STU 2.2 - Ballot

Da Vinci Prior Authorization Support (PAS) FHIR IG, published by HL7 International / Financial Management. This guide is not an authorized publication; it is the continuous build for version 2.2.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/davinci-pas/ and changes regularly. See the Directory of published versions

## Artifacts Overview

Page standards status: Informative

Complying with this implementation guide means complying with a number of profiles, extensions, value sets and custom search parameters. This page provides an overview of where this information can be found.

These FHIR artifacts define the clinical data that can be submitted as part of a prior authorization submission and/or included as part of a prior authorization response using the Claim submit operation.

The artifacts are of four types:

- Profiles constrain FHIR resources to reflect PAS requirements
- Extensions define additional data elements that can be conveyed as part of a resource
- Code Systems define PAS-specific terminologies to be used in one or more of those profiles
- Value Sets define the specific subsets of both PAS-defined and other code systems that can be (or are recommended to be) used within one or more profile elements
- Operations which define the PAS-specific constraints on the Claim submit operation as well as a Claim inquiry operation.

Many of the profiles are based on US Core 7.0.0 while also declaring conformance with US Core 6.1.0 and 3.1.1. In some cases, the 7.0.0 and/or 6.1.0 releases introduce new "mustSupport" elements that are not mustSupport in 3.1.1. The intention of this implementation guide is NOT to move forward the timelines by which EHRs and/or payers must support USCDI 3 and 4 content. Rather, it is to allow seamless transition as systems start to support the newer US Core releases as systems start to bring them on stream. As such, clients and servers have no obligations with respect to elements that are newly mustSupport in 6.1.0 or 7.0.0 beyond "don't error if these elements are present" until such time as those systems claim conformance with the US Core release which introduces those elements as mustSupport. Once a system claims conformance to US Core 6.1.0 or 7.0.0, then the conformance expectations of those release of the US Core guide come into play.

Terminology Artifacts can be found on its own page.

### Guide Artifacts

#### Capability Statements

- EHR PAS Capabilities - Required for EHRs participating in a PAS Exchange
- Intermediary PAS Capabilities - Required for Intermediaries (and/or Payors) participating in a PAS Exchange

#### Operation Definitions

- Submit a Prior Authorization Request for Adjudication - This operation is used to make a search for a Prior Authorization Response by example. This Prior Authorization $inquire operation is a query-by-example that follows the X12 278 Inquiry rules. The only input parameter is the single Bundle resource with a PASClaimInquiry instance (along with other referenced resources) and the only output is a single Bundle with zero-to-many PASClaimInquiryResponses (and other referenced resources) or an OperationOutcome resource.
- Search for a Prior Authorization Response by example - This operation is used to submit a PreAuthorization Claim Request for adjudication as a Bundle containing the PASClaimRequest and other referenced resources for processing. The only input parameter is the single Bundle resource with a PASClaimRequest instance (along with other referenced resources) and the only output is a single Bundle with a PASClaimResponse (and other referenced resources) or an OperationOutcome resource. This is a variant of the FHIR Core Claim $submit operation.

#### Metrics Logical Model

- PAS Metric Data Logical Model - A logical model describing the information that should be captured by PAS implementers about every PAS invocation to support measures evaluating PAS implementation

#### PAS Subsription Topic

- PAS Subscription Topic -

#### Profiles

##### Bundle Profiles

### Cross-Version Analysis

This is an R4 IG. None of the features it uses are changed in R4B, so it can be used as is with R4B} systems. Packages for both R4 (hl7.fhir.us.davinci-pas.r4) and R4B (hl7.fhir.us.davinci-pas.r4b) are available.

### Global Profiles

There are no Global profiles defined
