How does the analysis work?

Upload a photo or PDF of your bill. rekupr reads every line item, translates the CPT and ICD-10 codes into plain English, and checks each charge against 35+ billing rules, including CMS NCCI edits, duplicate-charge patterns, upcoding, and unbundling. Anything that looks wrong is flagged with the specific reason. Add your Explanation of Benefits and we line it up against the bill to surface any gap between what your insurer paid and what you are being charged.

Hospital bills, doctor visit bills, lab and imaging bills, emergency room bills, and Explanation of Benefits (EOB) statements. Any itemized medical bill from a US provider works, as a clear photo or a PDF. The clearer the document, the more we can read from it.

Is my medical information safe?

Yes. Your documents are encrypted in transit and at rest, and we run on HIPAA-compliant infrastructure. The original files you upload are deleted within days of analysis and never kept beyond 90 days. We never sell or share your information, and we do not use your documents to train AI models.

The summary is free, with no account required: how many issues we found, the amounts involved, and a preview of what we saw. The full line-by-line report, with plain-English explanations, code translations, and appeal letters, is $19.99 per bill, tax included.

What happens when you find an error?

We show you the exact line, what the code means, and the rule the charge appears to break, so you can judge it for yourself. The Appeals Center then researches the codes and payer rules behind the flag, gathers the evidence from your bill and EOB, and drafts an appeal letter for your situation that cites the relevant rules and tells you who to send it to.

Does rekupr replace a billing advocate or lawyer?

No. rekupr is a tool that helps you understand your bill and spot charges worth questioning. It is not a licensed medical billing advocate, attorney, or financial advisor. For complex disputes or denied claims, a professional may be the right next step, and rekupr helps you walk in prepared.

Built for the person paying the bill

Medical bills are already stressful. Advocating for yourself shouldn't be.

Between the confusing charges and the fear of missing something, appealing an incorrect bill on your own is exhausting. rekupr takes the overwhelm out of the experience by explaining what everything means, checking for errors, and creating a personalized appeal for you.

Finding the error is half of it

The appeal is the part people give up on. The Appeals Center does it with you: it researches the rules behind each flag, gathers the evidence, drafts the letter, and walks you through sending it.

Researches the rules
It pulls the billing codes, payer rules, and NCCI edits that apply to your flagged charges.
Gathers the evidence
Your bill, your EOB, and the supporting references, lined up so the dispute holds up.

To the billing department,

I am writing to dispute three charges on this account. Code CPT 36415 (venipuncture) appears twice on the same date of service, which reads as a duplicate charge. Code CPT 80053 was billed as separate labs rather than the bundled panel, contrary to NCCI edits.

Please review and adjust the balance accordingly...

Findings you can check, line by line.

Medical billing is high-stakes, so we hold our analysis to the standards of the people who work inside it. Here is how rekupr decides that something on your bill is worth questioning.

Grounded in authoritative data, not opinion

Every line is checked against licensed CPT code definitions, the ICD-10 diagnosis set, and the federal National Correct Coding Initiative (NCCI) edits, the same references professional coders and insurers use.

Deterministic rules, not AI guesswork

Overcharges, duplicate charges, unbundled panels, and upcoding are flagged by explicit rules tied to specific codes and amounts. We do not ask a model to "decide" whether a charge is wrong.

Every finding shows its evidence

When we flag something, we show the exact code, the comparison, and the dollar figure behind it, so you can verify it and take it to your provider or insurer.

Educational, never a black box

Our analysis helps you understand and question your bill. It is not medical, legal, or financial advice, and we always encourage you to confirm findings with your provider or insurer.

After the ER, I just wanted it over with. ChatGPT told me the bill looked normal, so I almost paid it. rekupr caught the upcoded charge and walked me through fighting it. I ended up paying less than half of what they first asked.
