The problem
Federal studies show that 19–25% of US hospital bills contain billing errors. Almost all of those errors are in the hospital's favor. Insurers won't catch them — they don't have the records. Hospitals won't catch them — the errors are profitable.
You have rights: the No Surprises Act, ERISA appeals, your state's consumer protection laws. But exercising them means decoding CPT codes, learning insurance jargon, and writing letters from scratch while you're already dealing with a sick family member or a recovery.
Audra does the part you can't afford an advocate for.
How it works
01
Drop a PDF, photo, or EOB. Your browser encrypts the file with AES-256-GCM before it ever leaves your device. Audra never sees plaintext.
02
Each charge is checked against federal billing codes (CPT/HCPCS/DRG), your insurer’s contracted rates, and your state’s billing protection laws. Errors, upcoding, and illegal charges surface in 60 seconds.
03
You get a clear savings estimate, a ready-to-send appeal letter, a phone script, and a 30-day deadline tracker. Copy and send.
Inside the audit
Audra's reports read like a senior patient advocate wrote them by hand. Every claim is backed by a specific rule from CMS, your insurer's policy, or your state's billing statutes. Hospitals respond to citations, not vibes.

What Audra catches
Every audit checks for the most common — and most expensive — patterns of US medical billing error. A typical disputed bill turns up two to four of these.
Duplicate charges
Same procedure billed twice on different lines or different dates.
Upcoded procedures
A routine visit billed at a higher complexity level than the record supports.
Unbundled charges
Charges separated that CMS rules require be billed as a single package.
No Surprises Act
Out-of-network charges from in-network facilities you never consented to.
Balance billing
Hospitals charging the gap when state law forbids it.
Phantom services
Procedures or supplies billed but never delivered.
Wrong CPT codes
Procedure codes that don’t match the documented service.
Missing pre-auth
Charges that should have been reduced when prior auth was obtained.

Grounded in the industry-published rates of billing errors on hospital bills. Conservative midpoint — your number is likely higher if you've had a hospital stay this year.

Estimated overcharges Audra could surface
$336per year
Based on industry data: ~60% of hospital bills contain at least one billing error, with an average error amount of ~7% of the billed total. Your number is likely higher if you had any inpatient stay, ER visit, or specialty imaging in the period.
Built for trust
Audra treats every uploaded bill as protected health information from the moment you drop it in. Read the full security overview.
Every file is encrypted in your browser with AES-256-GCM. The decryption key never reaches our servers in plaintext. Even if our infrastructure were compromised, your bills would be unreadable.
No ad networks. No data brokers. No sharing with insurers, hospitals, or marketers. Your bills are used to audit your bills. That’s it.
One click in Settings purges everything: bills, audits, profile, appeal history. Hard-delete, not soft.
How Audra works
Most AI tools generate confident-sounding text. Audra generates findings tied to a specific rule, with the citation in the appeal letter. Different category of product.
Rules
Every finding cites a specific rule: the No Surprises Act (45 CFR § 149.410), CMS National Correct Coding Initiative edits, Medicare Physician Fee Schedule allowables, and your state's surprise-billing statutes. We don't say "this looks high" — we say "this exceeds the CMS allowable for code 80053 by 28x."
Pipeline
A rules engine runs math validation, duplicate detection, unbundling checks against the live NCCI edit list, and benchmark comparisons against current CPT allowables. The AI only acts on what the rules engine extracted. It cannot invent line items or fabricate findings.
Sources
Appeal letters include the exact statute, paragraph number, and CMS reference behind each disputed charge. Hospital billing departments routinely concede when shown a regulation citation. Vague complaints get ignored; cited ones get refunded.
Privacy
Files are encrypted with AES-256-GCM in your browser. Only ciphertext reaches our storage. The per-file key is wrapped with a server-side master key (envelope encryption). Row-level security on every database table means even Audra engineers cannot query another user's bill data.
Pricing
Pay only when Audra finds something worth disputing. If we don't surface at least one finding worth more than the audit fee, the audit is on us.
