We recover denied claims. You pay only when a payer pays you back.
Hypex works invisibly behind your existing billing operation: deterministic appeals citing each payer's own policy, follow-ups that run on a clock, and recovery verified on the payer's own remittance. No added headcount, no upfront fee, no seat licenses. You keep 85% of every dollar we bring back.
The audit takes ~2 minutes and needs no signup - results render instantly.

The problem
Denials are rising. Most are never appealed.
Payers deny more claims every year, and denial work is pure labor: look up the rule, gather records, write the letter, chase the portal, follow up. Appeal volume scales with staff hours - so a large share of appealable denials is written off not because it lacks merit, but because nobody has a free Tuesday afternoon to fight it.
The industry's own numbers make the scale clear: initial denial rates sit in the low teens and climbing, roughly half of denied claims are never reworked, yet appeals that do get filed overturn at 40-80% depending on payer. The gap between "appealable" and "appealed" is where your revenue disappears.
Anatomy of an unworked denial

staff capacity is the ceiling
Sources: Change Healthcare denial index; MGMA rework surveys; payer overturn data (36-85% by payer, Medicare Advantage 57-80%). Hypex exists to close that last gap.
What we built
A working system that protects patient data and recovers revenue
Built to keep patient data out and to recover money you would otherwise write off, with your team in control at every step.
Patient data never leaves your environment
Identifiers are removed before anything is processed. Anything we cannot fully de-identify is rejected rather than stored, so protected data stays with you.
zero-PHIAppeals built to each payer's standard
Every appeal cites the specific denial reason and the payer rule it was judged against, in the format payer review teams expect.
payer-specificVerified, not self-reported
Recovery is confirmed against the payer's own remittance before we bill. You only pay us on dollars you can verify in your own system.
835-verifiedYour data, separated
Every organization's data is kept separate and access-controlled. Your workspace cannot read another's, and neither can ours read yours.

Click through the actual platform
Each tab is a real screen from the running Hypex console with de-identified demo data - not mockups. This is the same interface your team would use on day one.
Denial intake & triage
live platform · de-identified demo data
Every denied claim, de-identified. Batch-upload a CSV/835 or connect a clearinghouse feed; each claim is de-duplicated, scored for recoverability, and routed by payer rule. Identifiers were removed before anything reached this view.
Screenshots captured from the live production console. No PHI is shown anywhere.
How it works
From denial to recovered revenue
The workflow running in the live Hypex console today. Humans decide what ships; the system does the chasing, matching, and paperwork. Full detail lives on the How it works page.
Connect your denial feed
Share denials through your existing clearinghouse or a simple file upload - whatever your team already uses. Patient identifiers are removed immediately; only codes and amounts continue.
We find the real reason
Every denial is mapped to its true root cause - and whether it's worth appealing, what the filing deadline is, and exactly which evidence wins. Before any letter is written.
We draft, you approve
Appeals are written from your payer's own policy, with the cited rule shown beside each draft. Nothing submits without a person saying yes.
Get paid, then we bill
Approved appeals go out clean - checked for completeness, never filed twice. When money comes back, it's confirmed on the payer's own remittance, and our 15% applies only to what you actually received.
Silence gets chased
If a payer stays quiet, follow-up letters stage automatically on an escalating schedule for your reviewer to send. No appeal dies quietly in a queue.
Every outcome makes us smarter
You record won / partial / lost per appeal; those real results sharpen how the next denial is handled - for you and every client after you.
Roll out once it works
Start with one denial category and one payer, watch verified recoveries land, then expand at your pace. No upfront fee at any stage.

Architecture
Every claim on this page is enforced by code
Each capability below is something you get as a client - what it does for you, not how we built it.
Patient data can’t pile up
Identifiers are destroyed within minutes of use - automatically, with no manual step and no archive to breach.
zero-PHIThe real reason, every time
Each denial is mapped to its true root cause, whether it’s worth appealing, the filing deadline, and exactly what evidence wins - before any letter is written.
root causeAccurate letters, no AI roulette
Standard denials get precise letters assembled from your payer’s own policy. Complex cases get AI help that cites its source - and anything uncertain goes to a human, never out the door half-sure.
accuracy firstClean submissions, zero duplicates
Every resubmission is checked for completeness before it leaves, and the same appeal can never be filed twice - protecting your payer relationships and your compliance record.
clean claimsBilled only on money you keep
Your invoice comes from dollars the payer actually paid you - confirmed against their own remittance. Partial payments billed fairly; takebacks never billed at all.
fair billingSilence gets answered
Payers that go quiet are chased automatically on a schedule until they respond - and every win, partial, or loss sharpens how we handle your next denial.

What we do to protect PHI
Hypex operates as a business associate under HIPAA. Each control below carries an attestation stamp.
Zero-PHI test: request the verification package
A reproducible test asserts no patient identifier reaches the database, the model, or the letter store. Send a request and we email the runbook to your security team, so you can run it against our build before signing. Most vendors only assert this.
PHI never reaches the model
De-identified records only. The language model processes codes and tokens; patient data is not in its training, context, or storage path.
Encryption in transit and at rest
TLS 1.2 or higher on every connection. Managed encryption for storage and the database, with keys held in the cloud provider's key management service.
Access control and audit
Tenant-scoped data access, token or API-key authentication, IP-allowlisted machine ingest, least-privilege roles, and an append-only audit trail of every action.
Verifiable, not asserted
An open test suite asserts that no patient identifier reaches the database, the model, or the letter store. Your security team can run it themselves.
