201705 Attachments

Return to May 2017 Proposals

Attachments

Submitting WG/Project/Implementer Group

Attachments Work Group (AWG)

Justification

Electronic attachments are a high priority for processing claims and other payer/provider interactions. Current thinking has attachment submissions occurring via X12 messaging within the US, other countries have other mechanisms. However, there is substantial interest in experimenting with FHIR-based messaging for exchanging attachments. This track will explore the feasibility of this approach.

Roles

Please include information here regarding how much advance preparation will be required if creating a client and/or server.

Payer

Plays the role of a payer who may request and receive attachments. This is loosely analogous to the "FHIR Client - Claims Attachment Requestor" and "FHIR Client - Claims Attachment Processor" roles in the Financial Management track, but with a focus on content instead of process.

Provider

Plays the role of a provider who may receive requests for attachments and send attachments (solicited or unsolicited). This is loosely analogous to the FHIR Client - Claims Attachment Submitter role in the Financial Management track, but with a focus on content instead of process.

Scenarios

For all scenarios below, the following types of attachments are allowed:

• PDF attachment
• Unstructured C-CDA attachment
• Structured C-CDA attachment
• C-CDA on FHIR attachment

Solicited

Action: Payor sends an attachment request to the provider. Onus is on the payer to create the staple between the request and the attachment. Provider must return the payer's electronic staple (i.e. ID) with the attachment.

Here is an example of a request for an attachment from a payer:

http://hl7.org/fhir/2016Sep/communicationrequest-example-fm-solicit-attachment.xml.html

Here is an example of a solicited attachment from a provider (the payload would point to the PDF, C-CDA, or C-CDA on FHIR attachment):

http://hl7.org/fhir/2016Sep/communication-example-fm-solicited-attachment.xml.html

Precondition: None

Success Criteria: Provider receives the request, responds with the attachment, payer receives the attachment and is able to view it in their system.

Bonus point: Send to an adjudication engine in the Financial track.

Basic script for provider:

• Step 1: Assume payer has sent provider a communication request (example: http://fhirtest.uhn.ca/baseDstu3/CommunicationRequest/140045).
• Step 2: Provider uses the content of the request to craft a communication resource as the response (example: http://fhirtest.uhn.ca/baseDstu3/Communication/140046)
• Step 3: Provider creates an attachment (PDF, CDA, C-CDA on FHIR)
• Step 4: Provider POSTs the Communication resource and attachment to FHIR server.
• Step 5: Payer GETs the Communication resource and attachment and manually verifies the content.

Basic script for payer:

• Step 1: Payer crafts a communication request (example http://fhirtest.uhn.ca/baseDstu3/CommunicationRequest/140045).
• Step 2: Provider uses the content of the request to craft a communication resource as the response (example: http://fhirtest.uhn.ca/baseDstu3/Communication/140046)
• Step 3: Provider creates an attachment (PDF, CDA, C-CDA on FHIR)
• Step 4: Provider POSTs the Communication resource and attachment to FHIR server.
• Step 5: Payer GETs the Communication resource and attachment and manually verifies the content matches the request.

Unsolicited

Action: Provider sends an attachment to the payer in support of a claim without a request. Onus on the provider to create the electronic staple (i.e. matching IDs) between the claim and the attachment. Here is an example of a Communication resource for an unsolicited attachment from a provider (the payload would point to the PDF, C-CDA, or C-CDA on FHIR attachment):

http://hl7.org/fhir/2016Sep/communication-example-fm-attachment.xml.html

Precondition: Prior agreement in place between payer and provider.

Success Criteria: Payer receives the attachment and is able to view it in their system.

Bonus point: Send to an adjudication engine in the Financial track.

Prior Authorization

Action: Provider creates an attachment and sends it to the payer. Here is an example of a Communication resource for prior authorization (the payload would point to the PDF, C-CDA, or C-CDA on FHIR attachment):

http://hl7.org/fhir/2016Sep/communication-example-fm-attachment.xml.html

Precondition: Prior authorization has occurred, and the provider has an id (i.e. electronic staple) to associate the attachment with the claim.

Success Criteria: Payer receives the attachment and is able to view it.

Bonus point: Send to an adjudication engine in the Financial track.

TODO: Paul, how does the payer respond to the provider with an auth number and other info?
