Medexa.

Trusted AI for payer-ready approvals.

Medexa listens to the visit, codes it with evidence, and carries the claim all the way to a payer-ready approval — eligibility, prior authorization, submission and denial recovery, with a human approving every decision.

The problem

The paperwork is electronic. The work is still manual.

Eligibility checks and prior authorizations still mean staff re-keying data across portals, chasing requests by phone, and racing hard regulatory clocks — Dubai's pre-auth window is one hour. The result: slow approvals, avoidable denials, and clinical teams doing clerical work.

How it works

From conversation to payer-ready approval.

One loop, end to end — the encounter is captured once, and Medexa carries it the rest of the way.

01

The visit is captured ambiently

Medexa listens to the clinician–patient conversation. No dictation, no forms — say “Hey Medexa, start session” and see the visit documented as it happens.

02

Codes surface with their evidence

ICD-10 and CPT codes appear live in the room, each one linked to the exact words that justify it — so coding review starts from proof, not guesswork.

03

Everything becomes one clean record

Patient, coverage, encounter and codes normalize into canonical FHIR R4 — a single source of truth every downstream step reads from.

04

AI agents draft the decision

Eligibility and prior-auth agents consult a deterministic Rules Engine and draft the decision with a risk-readiness score — never a black-box “confidence.”

05

A human approves — always

Your reviewer sees the agent's reasoning and the named rule it cited, then approves, overrides or escalates. No unsupervised submission, ever.

06

Payer-ready, on your rails

Approved requests are signed and submitted over the rails you already run — DHPO / eClaimLink, NPHIES — and every outcome feeds the learning loop.

The agents

Five agents. One claim, carried to settlement.

Each agent owns one stage of the revenue cycle — and every decision it drafts cites the rule it applied.

Live

Eligibility

At registration

Verifies coverage the moment the patient registers — member ID, plan and policy checked against the payer before care begins.

Live

Pre-Authorization

Before care

Triggered by the ordered service itself. Drafts the prior-auth decision, cites the payer rule it applied, and starts the regulatory SLA clock.

Roadmap

Claim Submission

After approval

Assembles, scrubs and submits payer-ready claims over the rails you already use — no re-keying, no portal hopping.

Roadmap

Reconciliation

After payment

Matches remittances to claims automatically and flags underpayments and variances your team would otherwise never catch.

Roadmap

Denial & Appeals

After a denial

Drafts evidence-backed appeals — and learns which arguments actually overturn denials for each payer.

Submission, Reconciliation and Denial & Appeals are on the roadmap — shown in the product today so you can see where the platform is headed.

Why it's different

Built for trust, not just throughput.

A co-pilot, not another RCM

Medexa sits on top of the systems you already run. No rip-and-replace, no data migration — it integrates through the rails you already use.

Every decision cites its rule

A deterministic Rules Engine holds the payer- and procedure-specific rules. Each decision names the rule it applied — explainable and auditable by design.

It gets smarter with use

In shadow mode the agents run alongside your team. Every disagreement your reviewers resolve becomes a new rule — knowledge that compounds.

Trust is earned, per payer

Agents graduate from shadow to assist per agent and per payer, gated on measured agreement with your reviewers — not on promises.

Denials prevented, not appealed

A denial-risk predictor scores every claim before submission, with the factors and a fix-list — so problems are caught while they're still cheap.

Audit-grade by default

Every action — human or agent — lands in an immutable audit trail. SLA cockpits track the regulatory clock on every pre-auth in flight.
