How to search all Patient resources based on Identifier system and code?

Question

Hi

Without using custom search parameters, Can you do the following:

1. Search all patient FHIR resources based on identifer system and code (system and code value inside identifier property)
2. Search all Claim FHIR resources based on code value inside diagnosis property.

Thanks

P, Pioline (Cognizant) Thanks for posting your question in Microsoft Q&A. You can use Chained search to perform search operations on a resource within a referenced resource or Reverse chain search to search resources based on properties of resources they refer to.

Based on the description, you can try the following code snippet for your scenarios:

#1 GET [fhir-server]/Patient?identifier:system=[system]&identifier[code]=[code] (Patient.identifier has reference to Identifier)

#2 GET [fhir-server]/Claim?diagnosis.code=[code]

For other search examples, check out FHIR search examples which would be very helpful. I hope this helps and let me know if you have any questions.
