Denied claim & aged A/R recovery
The claims your practice wrote off aren't always lost.
Overturn works the denied and aged insurance claims your team no longer has hours to chase — payer follow-up, reprocessing and appeals. You keep your biller. You pay only on what we actually collect.
No patient data needed for the review. No setup fee. No retainer.

Why claims age out
It's rarely that the money isn't owed. It's that nobody has time to go get it.
New claims always feel more urgent than old ones. A denial that needs three payer calls gets pushed to next week — every week.
Every payer sets a deadline. Once a claim crosses it, the balance becomes permanently unrecoverable, no matter how valid it was.
When a billing team is stretched, the 90- and 120-day buckets quietly stop being worked and eventually get written off.
How it works
Proof before you commit to anything.
We start by showing you where the money sits in your own A/R — using a summary report that contains no patient information.
Send a de-identified summary
Export your A/R aging report with five columns: aging bucket, payer, CPT, denial code and balance. See the format.
Get a free review
Within about a week: where your aged A/R is concentrated, which denial types are typically workable, and what's nearing its filing limit. An estimate — honestly labelled as one.
Confirm on real claims
Every claim is different. After a BAA, we review a small sample with EOBs and history, then start a pilot on the claims that are actually workable.
Pay on collected cash
Billed monthly, only on payments posted to your practice from claims we worked.
What we do
One job, done properly: getting paid on claims that stalled.
We work alongside your existing billing team or billing company, on the claims they've had to set aside.
Payer follow-up
Status calls and portal checks on aged claims, so nothing sits unanswered past its filing limit.
Denial resolution
Root cause identified with the payer, then corrected and sent back for reprocessing — missing information, bundling, coordination of benefits.
Appeals
First- and second-level appeals for medical necessity, authorization and other contestable denials, with documentation and payer policy references.

Your data
The review doesn't need a single patient detail.
To size the opportunity, we only need a summary of your A/R — grouped by aging bucket, payer, procedure code and denial code. Every A/R system can produce one: Athenahealth, eClinicalWorks, Tebra, AdvancedMD, NextGen and others.
Claim-level work — where we do need access to individual claims — begins only after a Business Associate Agreement is signed.

Pricing
If we don't collect, you don't pay.
Contingency only
A percentage of the cash actually posted to your practice from claims we worked. The rate is set after the free review, based on the age and value of your claims.
- No setup fee, no retainer, no minimum term
- Nothing charged on claims that pay without our work
- Billed monthly in arrears, backed by remittance detail
- Never a percentage of your total collections
Why this structure
Some firms bill a percentage of everything collected during an engagement — including payments that were coming in anyway.
We only invoice on the specific aged claims you assign to us. If one of them pays and we didn't touch it, you don't pay us for it.
Start with the free reviewQuestions
What practices usually ask first.
Do we have to replace our billing team or billing company?
No. We work alongside them, on the aged and denied claims they've had to set aside. Everything under 90 days stays exactly where it is.
What happens if you don't recover anything?
You pay nothing. The only cost to you is the time it takes to export the summary report for the review.
Do you need access to our practice management system?
Not for the review — that uses a de-identified summary only. For claim-level work, yes, and only after a Business Associate Agreement is in place.
Who does the work, and where are you based?
Our team are accounts-receivable specialists who work US payer calls, claim reprocessing and appeals every day. We're based in Ahmedabad, India, and work US business hours.
Which practices is this a good fit for?
Specialty practices with meaningful claim values and a backlog of aged A/R — for example oncology and infusion, retina, imaging, gastroenterology, physical therapy and behavioral health.
Can every old claim be recovered?
No. Claims past their filing limit and contractual adjustments often aren't — though proof of timely filing or an underpayment can change that. Because every claim is different, the free review is an estimate from summary data. Before agreeing any recovery target, we look at a sample of your actual claims with their EOBs and history, so the numbers are based on your claims rather than averages.
