3 Steps. About a Minute.

Here is how the free review works:

  1. 1Upload 4 columnsA standard export from your practice management system. Payer, denial code, count, billed amount.
  2. 2Every code is classifiedAgainst payer rules and filing windows, from the rows you sent. Nothing is estimated.
  3. 3One page, straight awayWhat is winnable, what is already lost, what needs a clinician, and the dollars behind each.

What You Get Back

One page, sorted by what you can actually do.

Start my review
  • Winnable now

    Recoverable denials by payer and reason code, and what they add up to.

  • Already lost

    Past the filing window, or really a contractual write-down. No point chasing it.

  • Needs a clinician

    Winnable on the merits, but somebody has to attest to medical necessity.

Every figure is computed from the rows you send. Nothing is estimated, and where we are unsure about a code we say so rather than guessing.

Why Is This Free?

There is no catch, and here is the reason.

Your export shows us which denials cost practices the most. The review shows you what is recoverable. You keep the answer, whether you buy or not.

Your Questions Answered

What do I need to send?

A standard export from your practice management system with 4 columns: payer, denial code, count and billed amount. If you can export it, you can upload it.

Do you need patient data?

No. No names, no member IDs, no dates of birth, no dates of service. If your file contains any, the upload is refused on the spot and we name the column. It is never stored.

What comes back?

One page, straight away: what is winnable, what is already lost, what needs a clinician, and the dollars behind each. Where we are unsure about a code we say so rather than guessing.

Why is the review free?

Your export shows us which denials cost practices the most. The review shows you what is recoverable. You keep the answer, whether you buy or not.

What does AppealHound cost after that?

Start with a free review of your denials. If the numbers hold up, we agree terms with you after the review. No subscription to sign up front.

Where do I find this export in my system?

Any report that lists denials by reason code works: a denial summary, an adjustment report grouped by CARC, or an ERA/835 summary. If it has payer, denial code, count and amount, it works. Stuck? Email us the column names and we tell you which report to pull.

My report is in Excel. Is that a problem?

Save it as CSV first. In Excel: File > Save As > CSV UTF-8. In Google Sheets: File > Download > CSV. If you upload the Excel file, the page tells you the same.

Is the recoverable number real or an estimate?

Every figure is computed from the rows you send. Nothing is estimated. The classification is our own reading of each code, and codes we are unsure about are shown separately and not counted.

Does it work for commercial payers, or only Medicare?

The review works for any payer, because it reads the denial code. For Medicare we cite CMS national coverage policy. For commercial payers we look up the payer's published policy where we have it, and we say so when we do not. We do not cite local coverage (LCD) policies yet.

Do we have to change our practice management system?

No. There is no integration. You upload the 835 or an export your system already produces.

Will you contact our payers or our patients?

No. Your person approves and sends every appeal, on your rail and your letterhead. We never contact patients.

What about medical necessity denials?

They are flagged “needs a clinician”. The appeal is prepared, but somebody clinical has to attest before it goes out. Nothing is sent without it.
