Carta Health Review"Febrile overnight to 39.2. Blood cultures grew E. coli. Creatinine improving with fluids. Assessment: sepsis, urinary source, responding to treatment. IV antibiotics continued."
Every suggestion links to the exact words in the chart. Nothing is invented.

Upload the chart
Drop in the note or connect the EHR. No IT project, no new workflow for physicians.
AI proposes, with proof
Every suggested code arrives with the exact sentences in the note that support it.
The spine verifies
Deterministic checks against all 98,262 codes, severity tiers, DRG rules, and payment tables. The AI never gets the final word.
You approve and export
A person accepts every change. The selected codes go back to your EHR and on to whoever runs your billing.
Finds what the chart supports and the claim missed.
Missing diagnoses, codes that should be more specific, and codes the record does not support. Each finding shows the dollar impact and the reasoning, in plain language.
“Blood cultures from day 2 grew Escherichia coli; patient remains febrile, started on IV cefepime.”
Every code is proven against the official rulebook before you see it.
Carta Health does not rely on AI alone. A deterministic engine checks each suggestion against the official coding tables, so hallucinated codes, false positives, and invalid combinations are caught before they reach your queue.
Accuracy first. Upgrades only when the chart supports them.
Every chart gets an accuracy check first: the assignment the documentation actually supports, determined by rule. Only then does Carta Health look for more: if the record supports a more specific or higher-severity code, it shows you that option with the evidence attached. It never shops codes by payment.
Recovers money already left on the table.
Before touching tomorrow’s claims, Carta Health rescans the last twelve months of paid claims inside the rebill window and finds the ones worth correcting. That is money with no new patients attached.
Knows the difference between history and today.
Notes are full of old problems. Carta Health fences the current encounter from the patient’s history and screens history language deterministically, so resolved conditions never sneak onto a new claim. That is one of the most common denial triggers, gone.
Drops into the systems you already run.
The approved codes leave Carta Health in the formats your billing and interface teams already use. No rip and replace, nothing new to learn downstream.
Simple to start. Simple to keep.
Free
Full platform, no invoice. We would rather grow with the clinics that need this most than bill them.
Per reviewed discharge
Sized by your annual volume, with outcomes-aligned options. Large systems move to an annual subscription.
Accuracy here is architecture, not a promise.
The AI proposes
It reads the chart, drafts the codes, and cites its evidence. It never decides anything.
The spine decides
A deterministic engine checks every code against the official tables. Same input, same answer, every single time.
Your team approves
Nothing changes on a claim until a person accepts it. Carta Health drafts, your people sign.

Three jobs get easier the day Carta Health turns on.
Physicians check their own coding the way they spell check a note. Nurses and admin staff verify it without decoding medical language. Billing teams watch the savings add up.
Physicians
You select ICD codes in your EHR exactly as you do today. Carta Health reads your selections and your note together, flags what is missing, wrong, or unsupported, and shows the sentences that prove it. One pass, then back to patients.
Code the encounter the way you always have. Nothing new to learn.
Carta Health checks your selections against your own documentation.
Keep what is right, fix what it caught, get credit for the care you gave.
Nurses and admin staff
You verify the physician’s coding before it goes out. Every code explains itself in plain language, offers Carta Health’s own suggestion when it disagrees, and traces straight back to the patient’s records and the doctor’s notes. You never have to decode medicine to check it.
Each claim arrives explained in plain words, not in code.
Click any code and see the exact note lines behind it.
Agree, or accept the suggestion. Either way it is on the record.
CFOs and billing teams
Carta Health keeps score of what checking is worth: recovered rebills from the lookback, denials that never happened, lift per corrected claim, month after month. Every total drills down to the claim and the evidence behind it.
The lookback report lands. Findings on real paid claims.
Recovered and protected dollars, tracked over time.
Drill from any number to the chart line that earned it.
Community hospitals first.
Large systems staff armies of coders and consultants to fight for every dollar. Community hospitals run lean, and every denied or underpaid claim cuts deeper. Carta Health gives a lean team the same rigor, without adding headcount.

Built to protect patient data at every step.
Healthcare first, software second. Patient data stays encrypted end to end under a signed BAA, the AI reads and forgets, a person approves every change, and every action leaves a permanent, replayable trail.
How patient data is handled.
AES-256 at rest and in transit. Patient data is never stored or moved in the clear.
A signed Business Associate Agreement comes first, with every deployment. No exceptions.
The model reads the chart to do its job and retains no PHI afterward.
Nothing changes on a claim and nothing is submitted anywhere without a human approving it.
Every finding, question, answer, and approval is timestamped and replayable for auditors.
Role-based access for your team and ours. People see only what their job requires.
Read and forget. Nothing persists beyond the work itself.
A person approves every change and every export. By architecture, not by policy.
Common questions.
Where does our status stand on certifications?
HIPAA-aligned controls are in place today and a BAA is standard with every deployment. We are preparing for a SOC 2 Type II audit and will share the report once it is complete. We would rather tell you exactly where we are than put a badge on it early.
Does patient data train the AI?
Charts are processed to produce findings for your claims. Any use beyond that, including improving our models, happens only if your agreement and BAA explicitly allow it. You stay in control.
Can Carta Health submit a claim by itself?
No. The system drafts and verifies, but a person on your team approves every change and every export. That is an architectural rule, not a setting.
What does the AI actually see?
The minimum the job requires: the chart for the encounter under review and the claim data attached to it, under the BAA, encrypted in transit and at rest.
What happens if we leave?
Your claims, findings, and audit trail export with you, and PHI is deleted from our systems on a documented schedule you can verify.

Simple pricing. Free for clinics.
Hospitals pay per reviewed discharge. Large systems run on an annual subscription. And clinics are free, because tools like this should not be out of reach.
Start free. Scale when you’re ready.
No prices to decode. Clinics run free, and everyone else shapes a fair number with us on one call.
Full platform. No invoice. No catch.
Sized by your annual volume. Part of the fee can ride on recovered dollars, so it pays for itself.
Sized by discharge volume across your facilities. Outcomes-aligned options available.
Why free for clinics?
American healthcare loses billions every year to broken billing, and the smallest practices absorb the worst of it. We started Carta Health to help bend the cost curve of American healthcare. Tools like this should not cost so much that the people who need them most cannot afford them. If you run a clinic, we would rather partner with you and grow together than send you an invoice.
Common questions.
What does the free lookback cost?
Nothing. We rescan your last twelve months of anonymized claims and hand you the rebilling opportunities we find, and you keep the report either way.
How does pricing actually work?
The way this industry actually prices: by the discharge. Clinics run free. Hospitals pay per reviewed discharge, sized by annual volume, and part of the fee can be tied to recovered dollars so the platform pays for itself. Large systems move to an annual subscription across facilities. Exact numbers get shaped on a call with your volume, not on a pricing page.
Is there a lock-in?
No. The lookback commits you to nothing, and ongoing pricing is month to month unless you want otherwise.
Who approves what gets rebilled?
Your team. Carta Health packages each finding with its evidence, and nothing is resubmitted without your approval.
