How to integrate
- Read the (g)(10) documentation above. ONC criterion 170.315(g)(10) requires a standardized FHIR API for patient and population services.
- Register your application with the vendor, as its documentation describes.
- Authorize with SMART App Launch, or with SMART Backend Services for system-to-system access.
- Find the practice's FHIR base URL in the service base URL list.
- Plan for the gaps. (g)(10) certifies read access to USCDI data. Scheduling, charges, claims and write-back need vendor-specific APIs or another route.
