About Rebuttal
Built for the 99% who never fight back.
Every year, US health insurers deny more than 85 million claims. Less than 1% are ever appealed — not because patients don't have grounds, but because the system is designed to be exhausting.
Insurers know this. The denial letter is long. The deadlines are buried. The regulations are written in language nobody teaches you. Most people give up. Insurers count on it.
Rebuttal exists to change the math.
We built a system that reads your denial letter, identifies the exact federal regulations your insurer must respond to under penalty of law, and drafts a complete appeal letter — in seconds, for $9.99.
No law firm. No retainer. No six-week wait.
How we're different
We cite federal law, not templates.
Most appeal tools generate generic letters that insurers routinely ignore. Rebuttal maps your specific denial code — the CARC code on your explanation of benefits — to the exact federal regulations that govern your plan. Employer plans fall under ERISA § 503 and 29 CFR § 2560.503-1. ACA marketplace plans fall under PHS Act § 2719 and 45 CFR § 147.136. Your insurer's legal team knows these citations. Now your letter does too.
We evaluate every letter before you pay.
Before any letter reaches you — and before any charge is made — it passes an automated review. We verify that every regulatory citation in your letter exists in our verified database for your plan type, that no clinical advice has been included, and that the mandatory disclaimer is present. If the letter doesn't pass, we don't charge you. We don't ship letters we haven't verified.
We delete your document after delivery.
Your denial letter is processed in memory, used to generate your appeal, and then permanently deleted from our systems. We do not store, sell, or train on your documents. We do not retain your medical information. Your appeal letter is delivered by secure expiring link and then deleted as well. We keep nothing.
What we are not
Rebuttal is not a law firm. The letters we draft are for your review — they are not legal advice and do not create an attorney-client relationship. Every letter includes this disclosure prominently. We recommend verifying your specific plan deadlines and rights with a licensed professional before submitting any appeal.
