Proprietary Codes

Overview

Cerner’s implementation of the HL7^® R4 FHIR^® standard allows Millennium proprietary code values to be used in addition to standard value set codes. This allows developers to read and write data with clients’ proprietary codes, eliminating the need to map proprietary codes to standard codes. This is particularly beneficial for concepts that are highly customized by clients such as appointment and document types.

Millennium groups repetitive textual information into code sets. A code set stores numeric code values that represent textual or character displays. Code sets are consistent across all clients, however the values within a code set vary between clients and are only guaranteed unique within a specific EHR system. For this reason the region and the EHR source id (or tenant) are included in the system URL. See Multi-Region Support for further details.

The following are true for all Millennium proprietary codes:

The system value uses the following format: https://fhir.<region>.cerner.com/<EHR source id>/codeSet/<code set>
The code value is the numeric code value as a string
The display value is the code value display
The userSelected value is set to true
On inbound requests (POST, PUT, PATCH), proprietary codes and standard codes may not be set in the same coding array. If they are, the create or update request will fail with a 422 Unprocessable Entity response.

Example outbound CodeableConcept displaying both standard and proprietary codes:

Overview

Proprietary codes and systems that are dependent on a specific EHR system may include a Cerner cloud region in their system value. Unless stated otherwise below, the system value format is https://fhir.cerner.com/<EHR source id>/.

Region-specific Systems

The following regions override the format above with a region-specific system:

Canada: https://fhir.ca.cerner.com/<EHR source id>/
Asia-Pacific: https://fhir.au.cerner.com/<EHR source id>/

Exclusions

The proprietary systems that are not dependent on a EHR system will not include region in their system value, for example https://fhir.cerner.com/medicationrequest-category is applied for all regions.
