This instance of the External Validation Service Front-end (aka EVSClient) is configured to call the XUA validation service. 

***eHealth Exchange Content Testing ANNOUNCEMENT:*** 

The tools were last updated in August 2022 to remediate issues previously reported by participants.

All information related to the 2018 eHealth Exchange Content Testing Program can be found here https://ehealthexchange.org/testing-program/content-testing/

The User Guide, video and more information can be found at the eHealth Exchange website.

Questions should be emailed to testing@sequoiaproject.org. 

• Please note that you need to be logged into this tooling in the upper right corner order to perform content testing. 

• This tool is a user-friendly front-end to the validation web services offered by The Sequoia Project as part of the Interoperability Testing Platform (ITP).

• Value Sets reported for eHealth Exchange Content Testing come from the Value Set Authority Center (VSAC) hosted by the National Library of Medicine last updated August 10, 2022.

As of July 28, 2021, a validator was added to the drop down list under model based validators for testing against the USCDI version 1. This validator is provided for Participant use, but testing content is voluntary and passing this validator is not required.

KNOWN ISSUES - HL7 C-CDA R2.1

• CONF:1098-31579 and CONF:1098-7526 - These Errors should show as Warnings.  This has been reported to HL7 as an Errata (http://www.hl7.org/dstucomments/showdetail_comment.cfm?commentid=1856).  It appears that VSAC, which is our authoritative source of truth for the testing tooling related to value sets does not contain ALL the UCUM codes.  This effectively brings the valueSet validation to a SHOULD (since it’s only a fraction of all valid UCUM for current and near-future). We’ll be working with HL7 to help improve the valueSet for the UCUM codes, even though the binding was turned down to a warning. 
• CONF:1198-8476 - NUBC codes are licensed from AMA and the validator is missing some valid codes. Errors should be ignored for this conformance requirement. (SEQUOIA-373) & (SEQUOIA-382))
• CONF:81-7322 - Errors with this conformance reference should be labeled as CONF:1198-7365 to match the specification reference (SEQUOIA-442)
• CONF:1098-7419 - Validator is missing the Substance Reactant for Intolerance Value set 2.16.840.1.113762.1.4.1010.1 - Any errors reported for this should be ignored (SEQUOIA-456)
• CONF:1198-32928 - This error should be a warning, and is also mislabeled. Should be CONF:81-32928

KNOWN ISSUES - HL7 C-CDA R1.1 - Please NOTE that this specification is no longer being maintained by HL7 with regards to Errata processing.

• CONF:7419 - Validator is missing the Substance Reactant for Intolerance Value set 2.16.840.1.113762.1.4.1010.1 - Any errors reported for this should be ignored (SEQUOIA-456)
• Any Schematron related Errata for the HL7 C-CDA R1.1 specification found here will likely show as an error that cannot be remediated within the tooling for the foreseeable future as Sequoia depends on HL7 to maintain the Schematron.  There are 8 known issues logged that are Schematron related currently.
