medlistIQ
FHIR-native · rule-based · clinically vetted · deterministic

Clean medication lists
from messy data.

Your patient's meds are scattered across EHR orders, pharmacy dispenses, and self-reports. MedListIQ reconciles them into a deduplicated, clinically-classified list with a full provenance trail.

Many resources in. One clean med list out.

Reconcile across orders, dispenses, administrations, and patient-reported history using semantic matching — not just code equality. We handle the full terminology landscape (RxNorm, NDC, ATC, UMLS, free text) and derive status from auditable rules. Every medication ships with a provenance trail: inputs consumed, rules fired, fields enriched.

Typically three hires. One API.

Production medication reconciliation sits at the intersection of three specialties. Get the equivalent of three specialist hires as one API call — at a fraction of the cost:

Clinical pharmacy

What 'active' actually means when a stopped order and a recent dispense both exist. When to trust patient-reported meds. How to weight conflicting signals.

Health informatics

RxNorm TTY ranking (SCD > IN). SNOMED + NCIT enrichment for routes and methods. ICD-10 / SNOMED indications. Free-text to discrete.

FHIR integration

MedicationRequest / Dispense / Statement dedup. Inline codeableConcept vs. external medicationReference. US Core alignment. Bundle vs. flat-array.

Built for production use.

Every decision is auditable

Every inferred medication ships with its sources (which FHIR resources contributed), evidence (which rules fired), and enrichments (what we derived from the input). No black boxes.

Pick your payload

Three verbosity levels. `minimal` for a med-list UI alert. `standard` for EHR integration with RxNorm codes and dosage. `full` for clinical decision support with the complete provenance trail.

Normalized to the right codes

RxNorm SCD-preferred TTY ranking. SNOMED + NCIT mapping for routes and methods. ICD-10 / SNOMED for indications. Discrete data you can feed to downstream systems — or render human-readable.

Deterministic + versioned

Every response carries a ruleset_version (YYYY-MM-DD.vN). Pin to a version for stable integrations. No ML drift, no hallucinations, no unexpected behavior changes.

Stateless by design — no PHI persisted

Your FHIR payloads are processed in memory and discarded with the response. We never write patient data to disk. Only request metadata (timestamps, counts, status codes) is retained — for billing and observability, never the payload.

Who's building with this.

Care coordination

Platforms stitching records across multiple providers. MedListIQ dedups across EHR + pharmacy + patient input.

EHR integrations

Apps pulling meds from Epic, Cerner, Athena. MedListIQ normalizes the per-vendor quirks into one shape.

Telehealth + virtual care

Quick med-list ingest from a patient's uploaded records or HIE bundle. Ready for clinical review in seconds.

Clinical decision support

Rule engines need a clean active-medication input. Feed our output in; skip the reconciliation step.

“A medication inference engine built on substantive knowledge of prescriptions by an actual pharmacist — with zero introduced error from AI? That’s the dream.”

— Senior Clinical Research Scientist

“Wow. This is something we’d probably want to use.”
