Input profiles

MedListIQ accepts standard FHIR R4 medication resources. Any mix of the following in a single request:

• MedicationRequest — orders and prescriptions. Status, intent, dosage instructions, reason codes.
• MedicationDispense — pharmacy fills. Proves the patient actually received the drug.
• MedicationStatement — patient-reported or clinician-reported medication history.
• MedicationAdministration — administration events (inpatient / infusion settings).
• Medication — referenced via medicationReference from the above. Resolved during processing.

Pass them as a flat resources array, a FHIR Bundle, or both. No Patient or subject references required — requests are single-patient-scoped by the API key’s calling context.

​

Output profiles

Pick a response shape via the format request parameter:

• inferred_list (default) — our proprietary JSON: { medications, provenance?, meta }. Purpose-built for dashboards, UIs, and CDS engines.
• fhir_bundle — FHIR R4 Bundle of MedicationRequest resources. At verbosity=full, companion Provenance resources are included in the same Bundle, each targeting a MedicationRequest and carrying our inference evidence + enrichments as extensions.
• fhir_array — flat list of FHIR resources (no Bundle wrapper). At verbosity=full, the array contains MedicationRequest resources followed by Provenance resources, identified by their resourceType field. Pipeline-friendly.

Full shape-by-verbosity matrix, example payloads, and the list of custom extension URLs (confidence, evidence, enrichments) live in the Output formats guide.

​

Planned — US Core conformance

Not shipped yet. Once US Core 7.0 profiles are wired up (mandatory fields, must-support extensions, meta.profile stamping), we’ll add them as a new format value rather than repurposing the existing ones. No breaking changes to fhir_bundle consumers.

Code systems we produce

See the Enrichments catalog for how we populate each of these from raw input.
