Missing subscriber_id and group_number in FHIR Coverage Resource Response

Support

Situation
I am working on integrating insurance data from OpenEMR using the FHIR API.
When I retrieve the Coverage resource (using Coverage.read), I am able to get basic insurance information like status, beneficiary, and payor.

However, two important fields are missing from the API response:

  • subscriberId → The unique identifier for the insurance policy.
  • Group Number → The identifier for the insurance group.

These fields are essential for billing and insurance verification processes.

Here is a sample API response I’m receiving (sensitive data removed):
{
“resourceType”: “Coverage”,
“id”: “12345”,
“status”: “active”,
“beneficiary”: {
“reference”: “Patient/67890”
},
“payor”: [
{
“reference”: “Organization/98765”
}
]
// Missing subscriberId and group number
}
Question

  1. Is there any configuration or mapping in OpenEMR to include these fields in the FHIR Coverage resource?
  2. If not, do I need to modify the CoverageService implementation to expose these fields?
  3. Are there known limitations or planned enhancements for including these fields in a future version?

OpenEMR Version
I’m using OpenEMR version: 7.0.2

Browser
I’m using: Chrome

Operating System
I’m using: Windows 11

Logs
I have checked the logs, but I didn’t see any related errors.
I can share the specific API request/response if needed.

Coverage wasn’t a required certified field for the 3.1.1 version of US Core FHIR. We are updating FHIR to version 7 of US Core which will have this information.

You can grab a bunch of this information using the non-FHIR api also called the ‘standard’ api.

All of this will get released around the November/December timeframe.

I’m in working on this resource right now and can put a link up to the PR when I have something you can look at.
