Existing wording:

Therefore, CRD Clients SHALL provide support for Coverage Requirements Discovery without PHI using a redacted view where the resources exposed through the CDS Hooks and SMART on FHIR interfaces are filtered as follows:

AND

CRD Clients SHALL determine whether a CRD Service will use the PHI or non-PHI version of the CRD interface at the time the CRD Service is configured to have access to their system. In situations where PHI will never be required to perform Coverage Requirements Discovery, the redacted view SHALL be used. 

Issue:

Not all FHIR implementations have the capabilities to de-identify and strip out potential PHI as described. Therefore use of SHALL here is very prescriptive and unreasonable. Request to change it to MAY or SHOULD.

Proposed wording:

Therefore, CRD Clients MAY provide support for Coverage Requirements Discovery without PHI using a redacted view where the resources exposed through the CDS Hooks and SMART on FHIR interfaces are filtered as follows:

 AND

CRD Clients SHOULD determine whether a CRD Service will use the PHI or non-PHI version of the CRD interface at the time the CRD Service is configured to have access to their system. In situations where PHI will never be required to perform Coverage Requirements Discovery, the redacted view MAY be used.
