We take prior authorization denials off your plate.
Recover revenue lost to prior authorization denials, without hiring more staff or changing how your practice works.
Payer-specific. No new workflow to adopt.
Denied prior authorizations, appealed automatically.
MercuryAuth picks up denials as they come in, builds the appeal from the payer’s own rules and your patient’s chart, and files it without your team writing a word.

DeadlinesFollow-upOutcome
When a payer needs something only your team can provide, MercuryAuth tells you exactly what and why.
Protect revenue without adding more work.
A denial puts revenue at risk after you’ve already delivered care. We handle the appeal work so your team can stay focused on patients.
No new system to manage
MercuryAuth works alongside the workflow and EHR your practice already uses.
No appeal writing for your staff
We handle the records, policy analysis, drafting, submission, and payer follow-up.
No missed momentum
Every deadline and next step is tracked from the day the denial arrives.
Appeals today.
A smarter system tomorrow.
We start as a done-for-you appeals service. Over time, every appeal helps build a criterion-level map of what each payer actually approves - the foundation for a more intelligent platform.
Our approachBuilt from real appeals. Grounded in payer outcomes.
Human expertise delivers results
Software amplifies what works
One denial, one payer, one criterion-level argument, end to end.
Every outcome records what that payer accepted, at which criterion.
Those outcomes compound into a map of what actually gets approved.
Eventually the map does the work up front, before the denial is written.
Approval rate is the only metric that matters, and you cannot optimize it blind.
You cannot improve approval rate without knowing what a payer actually accepts. That is written down nowhere. The only place it gets recorded is in the appeal, in the gap between the denial that failed and the argument that overturned it.
So that is where we start. Not because appeals are the business, but because they are the only source of truth about what works.
Every appeal records what a given payer accepted, for a given treatment, at a given criterion. Over time that becomes the thing no one else has: a map of what actually gets approved.
Everyone else optimizes for speed. We optimize for whether you get paid.
The problem
A denied high-cost claim is not deferred revenue. It is often a loss you have already incurred.
No one on staff has the time or training to write a real medical-necessity argument for every denial.
The appeal window starts the day the denial lands, and it does not wait for a free afternoon.
Send the denial.We take it from there.
From understanding the denial to following up with the payer, we handle the details of your appeal.
-
You send the denial.
Forward it from your inbox or share it from your EHR. We coordinate access to the relevant clinical records.
-
We build the case.
Our AI connects the payer’s policy with the patient’s chart to prepare an evidence-backed appeal, including the clinical argument for medical necessity.
-
We file it and follow through.
We submit the appeal, track deadlines, follow up with the payer, and report the final decision back to your practice.
Why MercuryAuth
Every appeal makes the next one more informed.
We prioritize accuracy as well as speed.
-
Payer-specific intelligence
We record what was submitted, how each criterion was addressed, and what the payer ultimately decided. Over time, this creates a growing knowledge base of what works for each payer, treatment, and denial reason.
-
Built criterion by criterion
Every appeal is organized around the payer’s actual requirements. We connect each criterion to supporting evidence in the patient’s chart instead of producing a generic appeal letter.
-
Managed through the decision
We take responsibility for the operational work around the appeal: preparation, filing, proof of submission, deadlines, payer follow-up, and final outcome reporting.
-
Built around your existing workflow
MercuryAuth sits on top of the systems and processes your team already uses. Appeals fit into your day-to-day workflow, with less change for your practice and less disruption for your staff.
Intelligence that improves with every outcome.
One workspace per denied claim, from intake to outcome.
Nothing has been drafted yet. The criteria above are parsed from the payer's own published policy, not from a template.
Recorded to the map: Meridian accepted fourteen weeks of conservative therapy at §3.2 for CPT 22633. The next Meridian fusion appeal starts from that.

Have denials worth pursuing? Let us take a look.
We are onboarding a small number of specialty practices. If prior authorization denials are consuming staff time or leaving revenue behind, we would like to talk.
