Retrieve a patient's diagnoses

Retrieve a patient's diagnoses

You can use this action if you want to access a patient’s diagnoses—as documented by a specific organization. The EHR system returns a patient’s general diagnoses, problems, or health concerns. Typically, you can use this for offering:

  • patient education for specific conditions
  • targeted services to relevant patients

Supported systems

You can use this API action with the Redox FHIR® API.

Your connection's system can return results with their own FHIR® or query-based API.
