Da Vinci - Prior Authorization Support
0.1.0 - STU Ballot

Da Vinci - Prior Authorization Support, HL7 International - Financial Management Work Group - CI build for vesion 0.1.0). This version is based on the current content of https://github.com/HL7/davinci-pas/ and changes regularly. See the Directory of published versions

PAS IG Home Page

This specification is currently undergoing ballot and connectathon testing. It is expected to evolve, possibly significantly, as part of that process.

Feedback is welcome and may be submitted through the FHIR change tracker indicating “US Da Vinci PAS” as the specification.

This implementation guide is dependent on other specifications. Please submit any comments you have on these base specifications as follows:

  • Feedback on the FHIR core specification should be submitted to the FHIR change tracker with "FHIR Core" as the specification.
  • Feedback on the US core profiles should be submitted to the FHIR change tracker with "US Core" as the specification.

Note that this implementation guide is intended to support mapping between FHIR and X12 transactions. To respect X12 intellectual property, all mapping and X12-specific terminology information will be solely published by X12 and made available in accordance with X12 rules - which may require membership and/or payment.

Several of the profiles will require use of terminologies that are part of X12 which we anticipate being made publicly available. At such time as this occurs, the implementation guide will be updated to bind to these as external terminologies.

Overview

Prior authorization is an essential process in the management of healthcare costs by payer organizations. However, the process of requesting and receiving prior authorizations can be slow and inefficient. U.S. regulations mandate that X12 be used for communicating prior authorization requests and responses. However, few electronic health record (EHR) systems have implemented this interface. As a result, prior authorizations are often solicited by fax or by using payer-specific portals where clinicians re-key relevant information. Fax submission requires manual transcription on the payer side - and may result in significant back-and-forth requesting additional information prior to a decision being made. Re-keying information is inefficient and can result in data entry errors.

This implementation guide strives to enable direct submission of prior authorization requests from EHR systems using a standard already widely supported by most EHRs - FHIR. To meet regulatory requirements, these FHIR interfaces will communicate with an intermediary who, when necessary, can convert the FHIR requests to the corresponding X12 instances prior to passing the requests to the payer. Responses are handled by a reverse mechanism (payer to intermediary as X12, then converted to FHIR and passed to the EHR). Direct submission of prior authorization requests from the EHR will reduce costs for both providers and payers and result in faster prior authorization decisions - resulting in improved patient care and experience.

When combined with the Da Vinci Coverage requirements Discovery (CRD) and Documentation Templates and Rules (DTR) implementation guides, direct submission of prior authorization requests will further increase efficiency by ensuring that authorizations are always sent when (and only when) necessary and that such requests will almost always contain all relevant information needed to make the authorization decision on initial submission.

The implementation guide also defines capabilities around the management of prior authorization requests, including checking the status of a previously submitted request, revising a previously submitted request and cancelling a request.

A high-level summary of how all of these IGs will work together can be seen below:

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
  • HIPAA Regulations explains the relevant portions of the regulatory context in which this implementation guide operates
  • Formal Specification covers the detailed implementation requirements and conformance expectations
  • Artifacts introduces and provides links to the FHIR R4 profiles, operations 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 - draft - The balloted version of US Core based on FHIR R4. This implementation guide will be updated to be based on the final R4 release once it is published.

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