What are all those codes on the bill?
Medical bills list procedures as five-character codes — 99213, 80053, 70553 — with no plain explanation. Paste the bill, or type one code, and this page tells you what each common code means. It only explains codes it knows, never guesses, and never tells you whether the bill is right — that part is between you and your provider.

Paste the bill, or type a code.
Result
In one line
The decode runs in the page you already loaded — no upload, no account, no server call. And it only returns meanings from a fixed list, so it can't invent what a code means. See the proof →
How it works
A decoder, not an auditor
This tool does one thing: it translates the common procedure codes on a bill into plain English. It deliberately does not tell you whether a code was billed correctly, whether you were overcharged, or whether something looks like fraud — those are real questions, but answering them takes your actual plan and provider records, and a wrong guess could send you down the wrong path. So it decodes and stops there.
It also only knows a curated list of the codes patients see most. If a code on your bill isn't shown, it isn't in the list — ask your provider for a plain-language description, which they're required to help with on an itemized bill.
Once you know what it is
Knowing the code is step one
If the charge came with a denial, decode the denial reason. If it's a surprise out-of-network bill, check whether it's protected under the No Surprises Act. And the medical terms around the codes? The plain-language decoder handles those.
Questions
Common questions
Does the bill I paste get sent anywhere?
No. The decode is done by code already running in your browser. There is no server endpoint behind this page — what you paste never travels over the network and is not stored.
Will it tell me if I was overcharged?
No — on purpose. This tool explains what a code means, not whether it was billed correctly. Deciding that needs your specific plan and provider records. For a billing dispute, ask for an itemized bill and contact your provider's billing office and your insurer.
Why isn't my code listed?
The list covers the codes patients see most often. There are thousands of codes, and this is a curated, common subset — if yours isn't here, it isn't a mistake, it's just not in the list. Your provider must give you a plain-language description on an itemized bill.
Is this billing or medical advice?
No. It is a plain-language reference for common procedure codes, not billing, coding, or medical advice, and it does not diagnose anything.
