ARDIA PRECISION HEALTHGoverned AI for healthcare revenue & precision care
● The models behind Ardia

Every model we've built, in one place

Ardia is an AI healthcare-infrastructure company building governed models for lab reimbursement, precision medicine and elder care. This is the single, honest answer to "what has Ardia actually built?" — each model, its AI engine, the standards it works to, and exactly how far along it is.

The honest line: Ardia is pre-revenue, seed-stage, Dallas–Fort Worth, founded December 2025 — no clients, no revenue, no clinical results. Only two things here are measured: Cadence (95.45% held-out on public UCI HAR) and Meridian's unit-tested PAMA math. The persona models (Lumen, Aria, MolecuIQ, ToxIQ, PulmoIQ, TARA) run on a frontier model under guardrails and have no published accuracy yet — anything not measured is labelled a modelled target. Never a diagnosis; emergencies escalate to 911.

The roster, by focus

Ten models across four focus areas plus a governed core. Each carries an honest status badge: ● measured = real numbers you can reproduce, ▶ live demo = runs today on a frontier model under guardrails (watchable, no published accuracy), ◐ modelled target = specified and being built, not yet measured.

Lab reimbursement (RCM)

2 models

ToxIQ

Toxicology revenue-cycle model
▶ live demo

Reads a toxicology lab's orders and claims and reasons about coverage, coding and medical necessity before a claim goes out — so definitive and presumptive drug-testing claims are clean the first time instead of denied.

MolecuIQ

Molecular & genomic revenue-cycle model
▶ live demo

The molecular-diagnostics counterpart to ToxIQ: maps molecular and NGS orders to the right CPT and MolDX Z-code, checks the governing LCD/NCD, and flags necessity gaps before submission.

Precision medicine

1 model

MolecuIQ — genomics & pharmacogenomics

The same MolecuIQ engine, viewed through its genomics capability
▶ live demo

Interprets next-generation-sequencing and pharmacogenomic results against published clinical guidance — matching NGS panels and PGx variants to the relevant NCCN and CPIC recommendations so a clinician sees the guideline-backed context. It is decision support, never a diagnosis.

PAMA rate cliff

1 model

Meridian

Deterministic PAMA / CLFS rate-cliff model
● measured

Not an LLM — a deterministic engine that models the PAMA Clinical Lab Fee Schedule rate cuts and shows a lab exactly how much revenue is at risk as rates step down. The math is unit-tested so the numbers can never drift from the code, and it runs entirely in the browser with no PHI.

Pulmonary care

1 model

PulmoIQ

Pulmonary / respiratory model
▶ live demo

Focuses the reimbursement and documentation reasoning of the IQ family on pulmonary and respiratory care — pulmonary-function testing, spirometry and related services — checking coverage and coding before a claim is filed. Non-diagnostic.

Elder care

2 models

Aria

Voice-first elder companion
▶ live demo

A warm, voice-first companion for older adults — conversation, reminders and a gentle daily check-in. It listens for concerns, keeps a caregiver in the loop, and hands off to a human. It never diagnoses, and a suspected emergency is escalated to 911.

Cadence

Trained movement / activity-recognition model
● measured

The one genuinely trained-and-measured model in the stack: a movement classifier that recognises daily activity from motion signals to give a picture of an older adult's routine. Trained from scratch and scored subject-independently on a public benchmark — the test people never appear in training.

Plain-language reports

1 model

Lumen

Patient report & scan explainer
▶ live demo

Turns a dense lab report or imaging summary into plain, calm language a patient can actually read — explaining what a result means and what to ask their clinician, always pointing back to the source report. It clarifies, it does not diagnose.

The governed core

3 models

TARA

Clinical-reasoning core (neuro-symbolic)
▶ live demo

The reasoning core the persona models run on — a neuro-symbolic design pairing a frontier model's language reasoning with a symbolic policy engine that applies coverage and coding rules deterministically. It is administrative software, not an FDA medical device.

Sentinel

HIPAA de-identification kernel
◐ modelled target

The privacy gate every other model sits behind — a deterministic rule engine that strips identifiers so no PHI reaches a prompt, enabling work on a Limited Data Set under a Data Use Agreement. Being built to the HIPAA Safe Harbor standard.

Crucible

Evaluation harness
◐ modelled target

The evaluation harness that keeps everyone honest — the same subject-independent, reproducible-from-public-data protocol that produced Cadence's numbers is being generalised so every persona model gets benchmarked the same way, once real data is available under a BAA.

AI tools we evaluated & use

The persona models are not a single home-grown neural network — they run on frontier models under guardrails, with one classifier we trained ourselves. Here is exactly which tool does what, and how far each is proven.

Every persona listed on this page runs on Google Gemini under Sentinel's de-identification and TARA's policy guardrails. None has a published accuracy figure yet — that arrives model-by-model through Crucible, once measured on real data under a BAA.

Frameworks we're building

What we're building (Phase 1): the ingestion-and-adjudication spine that turns a lab's raw claims traffic into governed, auditable decisions. Four pieces, built in order.

1

EDI 835 / 837 ingestion pipeline

Ingests the standard claim (837) and remittance (835) EDI feeds so the system reads a lab's real reimbursement traffic — the raw material every downstream decision is built on.

2

Symbolic Policy Engine

Deterministic coverage logic: MolDX / DEX Z-codes, the governing LCD / NCD, and NCCI / UDT frequency rules applied as explicit rules — so a decision is explainable, not a black box.

3

Appeal-letter generator + audit trail

Drafts a sourced appeal letter when a claim is wrongly denied, backed by a tamper-evident audit trail so every decision and its rationale can be reconstructed after the fact.

4

HIPAA GCP + SOC 2 foundation

Will run on a HIPAA-eligible Google Cloud footprint under BAA — Vertex AI, Cloud Healthcare API, BigQuery, FHIR R4, pinned to us-central1 — on the path to SOC 2. Today's stack is Vercel + Gemini/Claude; the GCP footprint under BAA is on the roadmap.

Timeline

Governance & data — Limited Data Set + Data Use Agreement in place
Q3–Q4 2026
Ingestion + policy — EDI pipeline & Symbolic Policy Engine online
Q4 2026 – Q1 2027
Reasoning + appeal + audit — the adjudication spine end-to-end
Q2–Q3 2027
First lab pilot — retrospective backtest first, then live
Phase 4 (future): precision medicine — extending the governed spine into cardiovascular and oncology decision support. Sequenced deliberately after the reimbursement core is proven.
Regulatory posture: TARA is administrative software, not an FDA medical device (not SaMD). Built to SB 1188 US data-residency and operated inside the TRAIGA / HB 149 NIST AI RMF sandbox.
