Detective
Reads the denial
I read your insurer's letter twice. I pull out the specific policy section they cited, the claim ID, the deadline, and exactly which clinical criterion they say you missed. Most denials hinge on one sentence; I find it.
For patients who were told noThey said no.
They said no.
The math says appeal.
Upload your denial letter and we'll tell you, in twenty minutes, whether the policy your insurer cited actually applies — and how likely an appeal is to win. Free to look. Pay only for the letter.

The process
How Revetra works
It only takes three simple steps.
Step 1: Upload Your Denial Letter
Step 2: Understand Your Results
Step 3: Generate Your Appeal
A note for the person reading this
A denial letter does its damage on both ends — for the patient who can't make sense of it, and for the clinician who can't fix care that depends on it. The wording is hostile, the deadlines feel arbitrary, the implication is that someone official has decided. So most letters end up in a drawer. We built this for the moments below.
Tuesday, 11:47 pm
“I got home from a twelve-hour shift and there's a $2,800 bill for the MRI my doctor ordered. The letter says not medically necessary. I have no idea what that means or what to do.”
Saturday morning
“My son needs the medication his pediatrician prescribed. The insurer said he has to try cheaper drugs first. We already did that two years ago. Where do I even start?”
Three weeks after surgery
“They covered the surgery but not the anesthesiologist. I'm being told I owe $4,100 for someone I never met. I don't know how to argue with a 30-page policy.”
If you recognize any of those — or if you're the person trying to help someone through one — you're in the right place.
The team on your case
Six AI specialists, working like a firm would.
An appeal isn't one task — it's six different jobs. Each Revetra specialist has a focused role and hands work to the next. Below is what each one does, in their own voice. They're AI, not people. We're naming them so you can see what is doing what.
Researcher
Finds the winning policy
I look up your plan's actual coverage policy — not a paraphrase — plus CMS, ACR, AMA, and specialty-society guidelines that apply to your condition. I bring back the passages that contradict the denial, with sources.
Medical Records
Builds the clinical timeline
If you upload your chart, I read it the way a reviewer would. I pull out the dates, the prior treatments tried, the lab values — the evidence that your documentation already meets the criteria your insurer says it doesn't.
Letter Drafter
Writes your appeal
I write the appeal letter section by section, in the formal register insurers expect. Every clinical claim I write is tied to a real source — never a fabricated citation. You can refine any paragraph before you sign.
Citation Checker
Verifies every reference
Before your letter is finished, I check every cited passage against the actual source — page numbers, quoted text, dates. If something doesn't verify, it doesn't go in. This is the step that separates a real appeal from a fluent one.
Submission
Packages it to mail
I package the final letter — PDF and editable Word — with a payer-specific cover sheet, the right mailing address, and a one-page instruction card. You print, sign, and send. The work is done.
About the team being AI. Every specialist above is a Revetra system, not a person. We give them names and voices so you can see what's doing what — and so you can review, refine, or reject any step before your appeal is sent.
Before you upload anything
Whether Revetra is right for you
We're not for everyone. Below is when Revetra is the right tool — and when something else (a lawyer, your provider's billing office, an advocate) is what you actually need.
Revetra is right when
- 01You received a written denial or prior-auth refusal from a U.S. health insurer in the last 180 days.
- 02The denial is about medical necessity, coverage criteria, or prior authorization — not eligibility or premium issues.
- 03You can find or describe the clinical context — what was prescribed, ordered, or performed, and roughly why.
- 04You want a first-pass internal appeal — Level 1, signed by you, sent to your insurer.
Revetra is the wrong tool when
- 01You've already exhausted internal and external appeals and are considering litigation — that's a lawyer's job.
- 02You need medical advice. We don't diagnose, recommend treatment, or replace your physician.
- 03Your insurer is denying you coverage entirely (loss of eligibility) — that's a different process and we'll point you to it.
