Home / Free denial audit
Free for any US practiceSend us 90 days of ERA files. In two business days you get a plain-English report of every denial, what it cost you, and which ones you can still fix.
Short answer: a denial audit reads your 835 ERA files line by line, groups every denial by reason code, adds up the dollars, and flags the claims that can still be corrected or appealed before the payer's deadline. Ours is free, takes two business days, and starts with a signed BAA.
This is a sample built from made-up data for a small family practice. Your report uses your own numbers.

Sample only. Made-up practice, 90 days, 1,240 claim lines.
| Next step | Lines | Dollars | Typical codes |
|---|---|---|---|
| Fix and resend | 38 | $7,420 | CO-16 CO-4 CO-11 |
| Appeal before the deadline | 21 | $5,960 | CO-50 CO-197 CO-97 |
| Bill the patient | 64 | $4,180 | PR-1 PR-2 PR-3 |
| Write off (past the limit) | 9 | $1,380 | CO-29 |
| Total found | 132 | $18,940 |
In this sample, $13,380 was still recoverable by fixing or appealing claims before their deadlines. That is the number most practices care about first.
A handful of claims shows you a handful of problems. ERA files show every payment and every denial the payers sent you, with the exact reason codes. That is how you see the real pattern, like one payer denying the same code every week, or a front-desk step that keeps causing eligibility denials.
If you only want a quick look, the free 835 ERA reader explains a single file in your browser. For the full picture across 90 days, use the audit.
Yes. There is no fee, no contract and no card. You keep the report whether or not you work with us.
No. Many practices hand the report to their own team or billing company. If you want us to work the denials, we can talk about that after.
The 835 ERA files (electronic remittance advice) for the last 90 days. Your clearinghouse or billing software keeps them, usually under remittance or ERA. If you can't get 835 files, a denial or remittance report exported from your billing software also works.
We sign a Business Associate Agreement (BAA) with you before you send any file. Files are shared through a secure link, used only for your report, and deleted when the audit is done. The form on this page asks for business details only.
Two US business days after we receive the files. Large practices with many providers may take a little longer, and we tell you up front.
Your denial rate, every denial grouped by reason code with dollar totals, the claims you can still correct or appeal and their deadlines, possible underpayments if you share a fee schedule, and a short prevention list for your front desk and billing team.
Independent and small group practices in the US, and small billing companies that want a second look at a client's denials.
Look up any denial code in plain English, or read a single ERA file in your browser. Both are free and need no sign-up.
