Da Vinci - Member Attribution (ATR) List
2.0.0-ballot - STU 2.0.0 US

This page is part of the Risk Based Contracts Member Attribution List FHIR IG (v2.0.0-ballot: STU2 Release 1 Ballot 1) based on FHIR R4. The current version which supercedes this version is 1.0.0. For a full list of available versions, see the Directory of published versions

Official URL: http://hl7.org/fhir/us/davinci-atr/ImplementationGuide/hl7.fhir.us.davinci-atr Version: 2.0.0-ballot
Active as of 2022-12-05 Computable Name: MemberAttributionList

The following is the list of changes in STU2.

  • New operation has been added to provide a generic Bulk Export capability for the different DaVinci use cases. This operation will eventually be moved into the HRex Implementation Guide.
  • The Attribution List profile has been generalized to support multiple use cases which require Patient Lists. This profile will eventually be moved into HRex Implementation Guide.
  • Added the STU2 workflow diagram in the use cases section
  • Updated specification for usage of the Bulk Data IG for davinci-data-export operation
  • Updated specification on the usage of the reconciliation APIs for member-add and member-remove
  • New operation member-add has been added to support the reconciliation of the attribution list.
  • New operation member-remove has been added to support the reconciliation of the attribution list.

Overview

Member Attribution (ATR) lists are used between Payers and Providers for implementing risk-based contracts, value based contracts, care gap closures and quality reporting. The processes of establishing and exchanging member attribution lists are complex and time consuming. Currently there are no standards in use for establishing and exchanging risk-based contract member lists between payers and providers. The most common method in use today involves creation of files (CSVs, txt etc) and exchanging them using different methods such as Email and Secure File Transfer Protocol (SFTP).This implementation guide will use HL7 FHIR to specify standards for exchanging of Member Attribution Lists between providers and payers. The list can be used by providers and payers to implement use cases for Value Based Contracts (VBC), Quality Reporting, Da Vinci Payer Data Exchange (PDex), Da Vinci Clinical Data Exchange (CDex) among others.

The purpose of this implementation guide is to define the mechanisms (APIs, protocols), data structures and value sets to be used for exchanging the Member Attribution List. The Member Attribution List typically contains the following information:

  • Plan/Contract information which is the basis for the Member Attribution list
  • Patient Information
  • Attributed Individual Provider Information
  • Attributed Organization Information
  • Member and Subscriber Coverage Information

The implementation guide is designed to allow

  • Exchange of a Full Member Attribution Lists.
  • Requesting changes to existing Member Attribution Lists.

The following features are in scope for future versions of the implementation guide

  • Notification of changes in Member Attribution Lists
  • Exchange of partial Member Attribution Lists which contain information about changes and not the complete list.

The following aspects are not in-scope for the implementation guide

  • Member Attribution List Creation and Reconciliation processes and workflows used by payers and providers

Content and organization

The implementation guide is organized into the following sections:

  • Use Cases and Overview describes the intent of the implementation guide, gives examples of its use and provides a high-level overview of expected process flow
  • Technical Background describes the different specifications this implementation guide relies on and indicates what developers should read and understand prior to implementing this specification
  • Formal Specification covers the detailed implementation requirements and conformance expectation
  • Artifacts introduces and provides links to the FHIR R4 profiles, search parameters and other FHIR artifacts used in this implementation guide
  • Downloads allows download of this and other specifications as well as other useful files
  • Credits identifies the individuals and organizations involved in developing this implementation guide

Dependencies

This implementation guide relies on the following other specifications:

  • FHIR R4 - The ‘current’ official version of FHIR as of the time this implementation guide was published. See the background page for key pieces of this specification implementers should be familiar with.
  • US Core STU3 - The US Core version based on FHIR R4.
  • Bulk Data IG - The Bulk Data Implementation Guide that will be leveraged as part of this IG.
  • SMART on FHIR Backend Services Authorization - Security protocols to be used for exchanging the Member Attribution List.

This implementation guide defines additional constraints and usage expectations above and beyond the information found in these base specifications.
