Thank you for the reply Keifer.
I've update the Statement Account search to use the Account identifier value with the
https://fhir.cerner.com/accountnumber identifier. X-Request-ID: c362ac380f69db9524170d39f47f69d5. I got Account identifier value from a Financial Account search. That is also returning a 404 error, Resource not found. According to the documentation, it seems that this should be a valid search. Then is not a valid search? If is not, then is there a way to get the Statement Number for a Patient from another resource?
Thank you.
