Assistance Required: Retrieving Patient Billing Information via Cerner FHIR

[Amanpreet Singh]

Hello Team,

I am currently working on retrieving billing information for a patient through the Cerner FHIR APIs. I explored the /ChargeItem endpoint; however, I observed that it does not support direct filtering by Patient ID. Instead, ChargeItem queries must be performed using either the Encounter (context) or Account resource identifiers.

So far, I have:

1. Fetched the Patient details and verified the identifiers.

2. Retrieved the patient’s Encounter data (e.g., Encounter ID: 97954262).

3. Attempted to call the ChargeItem API using the Encounter reference:

   GET /ChargeItem?context=97954262&-status=billable

   However, this did not return billing information.

4. I also attempted to use the Federated Person Principal Identifier (e.g., URN:CERNER:IDENTITY-FEDERATION:...), but I learned this is not the correct Account reference for billing, as ChargeItem requires a FHIR Account ID, not a federated identity value.

To proceed, I need guidance on:

• How to correctly retrieve the FHIR Account resource associated with the patient or the encounter.

• Confirming whether the Account or ChargeItem FHIR financial resources are enabled in our Cerner environment.

Any assistance or pointers would be appreciated.
