When you say that you can use the HIE's to contribute new data to the providers in the network, is that data actually going into the EHR's as if it was a record added in the EHR directly? If not, where are these contributed documents being stored?
We support 2 methods: (1) uploading FHIR data: https://docs.metriport.com/medical-api/api-reference/fhir/cr..., or (2) uploading documents like C-CDAs, PDFs, and images: https://docs.metriport.com/medical-api/api-reference/documen....
If you send Metriport FHIR data we'll convert it to C-CDAs under the hood when responding to providers in the HIEs, and this data is parsed and integrated as structured data directly in the EHR in the patient's chart. Same thing goes if you upload C-CDAs to Metriport yourself.
You can also share binary docs like PDFs and images, those will also be included in the patient chart in the EHR, but not parsed to discrete structured fields for display.
So concretely, by using Metriport you can pull data from EHRs connected to the HIEs we connect to (like Epic or other major EHRs like Cerner, Athena, etc), and send data back, so that the provider using the EHR can see the updated patient data directly in the chart in the UI.
