Why we built Denial Decoder

It started with a letter my father got in the mail.

He'd had a scan his doctor ordered - nothing optional, nothing cosmetic. A few weeks later, the insurance company sent back a page of dense, cold language that, as far as either of us could tell, said they weren't going to pay for it. What it actually meant, what we were supposed to do about it, and how long we had to do it - none of that was clear. It read like it was written to be given up on.

So I did what a lot of people do: I spent hours on hold, got transferred, got vague answers, and nearly accepted the bill just to make the stress stop. It was only by accident that I learned the denial could be appealed - and that appeals like his are overturned far more often than people realize. We filed one. It worked.

That stuck with me. My father had me to sit on hold and dig through the fine print. Most people don't. They get the same confusing letter, assume "denied" means "final," and quietly pay for care their plan should have covered - or skip the care altogether.

You paste your letter, and in plain English it tells you why you were denied, your deadline, the exact steps to push back, and the documents to gather - then it can draft your appeal. No account, and we don't store your letter on our servers - it's never used to train AI.

We built it for patients, because we were one. We hope it helps you fight for the care you've already paid for.
