Modern UM.

Built for independent TPAs, self-insured employers, and the clinical operations inside larger benefit organizations.

How We Engage

External service,
or an extension
of your team.

VantaUM sells Med Review. When you use Vanta med review under UM's contract, the Brief Engine drops into the way you already work — across the book or on the cases that carry the most clinical time. It is not a standalone UM product, and it is not included if another shop does the review.

Under that contract the workflow is the same: a single clinician carrying each case from concierge intake through authorization and first-level appeal, with documentation prepared to be IRO-ready. Full IRO stays on the VantaHG lane.

Built for the teams that run the plan. Independent TPAs, self-insured employers, and the clinical operations inside larger benefit organizations — without inheriting anyone's technical debt.

The Workflow

One case.
One owner.
No handoffs.

Utilization management is where authorization decisions get made, appeals get filed, and documentation has to hold up when it's tested. Most operations split that journey across a queue of reviewers and lose the thread between every stage.

Under UM's Vanta med-review contract, VantaUM runs one continuous workflow: a concierge opens the case, the Brief Engine pre-briefs it, and a single clinician carries it through the authorization and the first-level appeal — leaving a file that's already IRO-ready. Full IRO stays on the VantaHG lane.

—Concierge intake. A named coordinator owns the record — no portal queue, no triage relay.
—AI Brief Engine. Every case pre-briefed against clinical criteria before a clinician opens it.
—Same clinician through first-level appeal. Continuity, not a relay race between reviewers.
—IRO-ready documentation. Clean, criteria-cited files. Full IRO is a separate service, only on escalation.

Packaging

Paid door: Med Review.
UM included with Vanta.

The commercial SKU is VantaUM Med Review. Brief Engine / utilization management is included free only when you use Vanta med review under UM's contract — not sold as a standalone UM product, and not included if another shop performs the review. VantaHG is IRO and IDR only. Terms are scoped on a conversation — we do not publish a standalone UM price.

Included — Vanta Med Review
Authorization
+ First-Level Appeal

One team, start to finish. Your dedicated clinical team owns your relationship from intake through outcome — one point of contact, full visibility, all the way downstream. And when a case moves to appeal or peer-to-peer, the decision transfers to a fully independent physician who had no part in the original determination. That separation isn’t just our policy — it’s the law, and it’s built into our platform so it can never be skipped. Your team stays with you. The decision changes hands.

When a case escalates beyond first-level appeal to full independent review, that work stays on the VantaHG lane. The file arrives already clean and IRO-ready from the included Brief Engine work. Terms are scoped separately — we do not publish a UM or IRO price here.

Specialized Capability

The same engine,
tuned for your
hardest cases.

The whole platform runs your everyday utilization management. But out-of-network is its own discipline — high-stakes, appeal-prone, and unforgiving on documentation — and it's where VantaUM is genuinely differentiated.

For out-of-network work, the same concierge intake, Brief Engine, and single-clinician continuity become a precision instrument: defensible authorizations, first-level appeals owned by the same reviewer, and files documented to independent-review standard. If a case escalates, full IRO stays on the VantaHG lane — not sold as standalone UM, and not included with another shop's review.

It's the capability ASOs and larger benefit organizations come for — and it sits on top of the general UM layer everyone else uses every day.

“The cases that decide your exposure”

Out-of-network authorization, the appeal that almost always follows, and the documentation that has to survive independent review. This is the slice of UM where specialized clinical ownership pays for itself — and where a clean file is the difference between a defensible decision and an expensive one.

General UM, end to end
Authorization through first-level appeal across your self-funded book — the everyday workflow, owned by one clinician per case.
Out-of-network, specialized
The same engine aimed at your highest-exposure cases, with documentation built to independent-review standard.
IRO when it escalates
Full independent review available as a separate escalation service — picking up a file that's already clean.

Our Philosophy

The Brief Engine is
the secret sauce.

Every case arrives as a stack of raw documents. The slow part isn't the clinical judgment — it's everything that has to happen before a clinician can exercise it.

The Brief Engine collapses that. It ingests the record, matches it against criteria, and hands the clinician a fully pre-briefed case. That's what lets one reviewer move fast, stay consistent, and carry the same case from authorization through appeal — leaving documentation clean enough to hand straight to an independent reviewer.

The VantaUM Model

Three layers.
One case through appeal.

01
Concierge Intake

A dedicated, named coordinator opens each case and assembles the record. They know the criteria, the provider relationships, and the case history. Available. Accountable. Never a portal queue.

Human-first
02
AI Brief Engine

The secret sauce. It extracts and classifies the clinical record, cross-references evidence-based criteria, and prepares the full brief before a clinician opens the file. That's what makes the workflow fast and consistent — and the documentation IRO-ready by default.

AI-powered
03
Same Clinician, Through Appeal

Board-certified specialists in active practice — the same reviewer who owns the authorization owns the first-level appeal. Continuity, not a queue. When a cardiology case arrives, a cardiologist carries it the whole way.

Clinical excellence
“

Most operations split a single case across a queue of reviewers and call it scale. We built VantaUM so one clinician owns the case from authorization through appeal — because continuity is what makes the documentation hold up.

Why VantaUM

What a generalist
UM queue won't tell you.

Most UM operations were built to process every case the same way. VantaUM was built around clinical ownership — one reviewer per case, from authorization through first-level appeal — with the documentation to back the decision when it's tested. It's why it holds up on everyday UM and shines on your hardest out-of-network cases.

Accreditation

Documentation
that holds up under
independent review.

A determination is only as strong as the record behind it. VantaUM is built to the standard that matters when a case is tested — URAC-aligned, criteria-cited, and ready for an independent reviewer the moment it's written.

IRO-ready by default
Every case is documented to independent-review standard during the included Brief Engine work — not reconstructed under deadline once a case escalates.
Criteria-cited determinations
Each decision is tied to the evidence-based criteria behind it, so the rationale is clear to a provider, an auditor, or an independent reviewer.
Credentialed clinical rigor
A credentialed operation that the most regulated programs and the most demanding self-funded plans can stand behind — signaled before a single conversation begins.
