The workflow won't be any different for different providers.  In all cases, as an order is being written or appointment is being being booked CRD will be called and it will provide information about whether the service is covered at all, whether prior authorization is needed, or any other guidance it has. If the workflow is "query to see what benefits exist, then order accordingly", CRD won't help with that as querying for plan benefits is out of scope. However, we will update the specification to explicitly call out its utility for specialty providers and ensure that at least one of the use-cases shows specialty practice use. Will make this a 'sad path' scenario where the result from the payer is "this service is not a benefit and will not be covered, and patient opts to not receive care". Will do this as part of the change made in FHIR-36576
