Code Systems & Identifiers

Code Systems & Identifiers

Projo defines code systems and identifier systems under the same two namespaces as its extensions:

Namespace	Used for
https://projo.evoleen.com/fhir/...	Projo-owned code systems and identifier systems
https://firearrow.io/fhir/...	Transport-shared code systems (configurable via EXTENSION_BASE_URL)

Projo-owned code systems

System URL	Codes	Description
https://projo.evoleen.com/fhir/CodeSystem/task-business-status	waiting-for-delivery, invited, reminder-sent, collecting-responses, responses-collected, delivery-failed, expired	Task business status lifecycle. Bound to Task.businessStatus.
https://projo.evoleen.com/fhir/CodeSystem/task-output	communication-request, questionnaire-response	Discriminator codes for Task.output entries, indicating which referenced resource was produced.
https://projo.evoleen.com/fhir/CodeSystem/plan-slot-kind	onboarding, default, re-engagement, onboarding-routing	Kind of plan slot declared via the plan-slot Organization extension. Drives which PlanDefinition is applied at which lifecycle stage. ADR 0002, ADR 0007.
https://projo.evoleen.com/fhir/CodeSystem/extraction-provenance	sdc-extraction	Provenance activity code marking resources produced by SDC $extract.
https://projo.evoleen.com/fhir/CodeSystem/routing-provenance	clinical-routing	Provenance activity code marking resources produced by clinical routing (e.g. Flags created from extraction).
https://projo.evoleen.com/fhir/CodeSystem/bounded-action	enroll-plan, supersede-plan, route-to-review (implemented); notify-practitioner, raise-flag, send-message, create-task, assign-careteam (designed, not implemented)	Action codes for bounded PlanDefinition outputs. The implemented codes are produced by $apply; the designed-only codes are reserved for future knowledge artifacts.
https://projo.evoleen.com/fhir/CodeSystem/extraction-writeback-target	subject	Target of extraction writeback. Used by the extraction-writeback Questionnaire extension. ADR 0010.
https://projo.evoleen.com/fhir/CodeSystem/extraction-writeback-mode	fill-if-empty	Writeback mode. Currently only fill-if-empty is defined. Used by the extraction-writeback Questionnaire extension. ADR 0010.
https://projo.evoleen.com/fhir/CodeSystem/identity-resolution-reason	no-match, multiple-matches, non-conversational-only, no-active-cr, unresolved-receiver	Reason code recorded on a reverse CommunicationRequest when identity resolution could not be completed. Bound to the identity-resolution-reason extension.

Fire-Arrow-shared code systems

System URL	Codes	Description
https://firearrow.io/fhir/CodeSystem/communication-medium	whatsapp, rcs, web	Channel used to send or receive a CommunicationRequest / Communication. rcs added by ADR 0012; web by ADR 0011.
https://firearrow.io/fhir/CodeSystem/communication-category	invitation, question, answer, reminder, abandoned, completion	Category codes classifying Communication / CommunicationRequest resources by purpose in the conversation.
https://firearrow.io/fhir/CodeSystem/cr-category	identity-resolution-required, reminder	Specialized category for reverse CommunicationRequests (inbound-driven). identity-resolution-required marks a CR that needs server-side identity resolution; reminder marks an outbound reminder.
https://firearrow.io/fhir/CodeSystem/managed-subscription	sidecar-cr-events, projo-cr-status-events, projo-identity-resolution-events, projo-careplan-bootstrap	Discriminator codes for managed FHIR Subscriptions. Each code names a subscription topic that one of the three apps owns. See Subscriptions.
https://firearrow.io/fhir/CodeSystem/careplan-scheduling	scheduled	Server-owned flag written by Fire Arrow's $subscribe-due-events operation to mark a CarePlan activity as scheduled for due-event evaluation.

Identifier systems

System URL	Used on	Value format	Description
https://firearrow.io/fhir/identifier/whatsapp-bsuid	Patient.identifier (and related resources)	Meta business-scoped user id (string)	WhatsApp user-scoped id. Used to match inbound messages to a patient.
https://firearrow.io/fhir/identifier/wamid	Communication.identifier	WhatsApp message id	WhatsApp message id (wamid). Round-tripped from the WhatsApp API.
https://firearrow.io/fhir/identifier/inbound-sender-phone	CommunicationRequest.identifier (reverse CR)	E.164 phone number	Sender phone number for a reverse (inbound-driven) CommunicationRequest.
https://firearrow.io/fhir/identifier/inbound-business-phone	CommunicationRequest.recipient[].identifier	E.164 phone number	Receiving business phone number for a reverse CommunicationRequest.
https://projo.evoleen.com/fhir/identifier/extracted-resource	Observation.identifier, Condition.identifier (and other extracted resources)	<qrId>#<ResourceType>#<codeSystem>#<code>#<contentHash>	Stable identifier minted by SDC extraction writeback. Enables idempotent re-extraction: the same QuestionnaireResponse yields the same identifier, so re-running $extract updates rather than duplicates. ADR 0010.
https://projo.evoleen.com/fhir/identifier/routing-resource	Flag.identifier	<qrId>:review	Identifier on Flags created by clinical routing, linking the Flag back to the source QuestionnaireResponse review task.
https://projo.evoleen.com/fhir/identifier/organization	Organization.identifier	Tenant-defined	External identifier for the organization.
https://projo.evoleen.com/fhir/identifier/projo-azure-identity	(server-side only)	Azure-resolved identity reference	Server-side identity resolution marker. Written by the orchestrator when an Azure-backed identity lookup resolves a patient.
https://projo.evoleen.com/fhir/identifier/ciam-unique-client-id	(server-side only)	CIAM client id	Server-side CIAM identity resolution marker. Written by the orchestrator when a CIAM unique client id resolves a patient.
