RFA Assist · a ReviewBox product

AI-drafted RFA appeals grounded in IMR precedent.

RFA Assist is an AI workflow that helps physicians respond to Request for Authorization denials and draft Independent Medical Review (IMR) appeals — using a corpus of prior IMR decisions to ground every argument in real precedent.

The problem

Treatment requests get denied. The physician knows the request is medically necessary — but writing a winning appeal means knowing which arguments and which guideline citations have actually succeeded at Independent Medical Review, not just what sounds persuasive in the abstract. That knowledge lives in tens of thousands of historical IMR decisions, and no clinician has time to search them.

What RFA Assist does

Reads the denialIngests the UR denial letter, the original RFA, and supporting chart documentation.
Surfaces precedentSearches a corpus of prior IMR decisions for analogous cases where similar requests were overturned.
Drafts the appealProduces a structured response citing specific guidelines (MTUS, ACOEM, ODG) and analogous IMR holdings.
Cites everythingEvery guideline quote and IMR reference is linked, so the physician can verify before submitting.
Physician-editedThe draft is a starting point. The physician edits, adds clinical reasoning specific to the patient, and signs.
Works with ReviewBoxPulls record context from ReviewBox when the chart has already been processed there.

Why grounded in IMR precedent

A generic LLM can write a fluent appeal that loses. RFA Assist is built around the idea that the right argument is the one IMR has already accepted in analogous cases — so we anchor every draft in the specific guidelines and precedent decisions that actually move the needle. Citations, not vibes.
