Medical billing
A medical bill that doesn't look right. Keep the record while you sort it out.
A medical bill can be wrong in many ways: a service you didn't get, a charge made twice, an amount your health plan says you shouldn't owe. Sorting it out takes calls, letters and patience. Keep each one.

You're disputing a bill
- The bill, and the itemized version if you've asked for one
- Your plan's explanation of benefits for the same visit
- Every call to the provider and to your plan: date, who, what was said, any reference number
- Every letter you sent, and the date it went
- Payments you've made
A provider or billing office is chasing you
- Each statement, with the date it arrived
- What you've already paid, and when
- Any request you made to pause billing while it's checked, and the reply
- Any payment plan offered, in writing
- Any notice that the bill has gone to collections
Health information in a case is handled as set out on the health data privacy page. Only your account can see your case.
How it works
One record, either way round.
Everything in one place. Your own notes, photos, files, emails, pasted texts and voice notes go into one dated register for this case.
Two dates on every entry. When it happened, and when you wrote it down. The second date can’t be changed, not by you and not by us.
Letters for both directions. 84 letters, eight of them written for the person answering. Each one fills in the facts from your record and leaves the ask blank. What you want is yours to write. Nothing is sent for you, and when you send one, it goes back into the record as a dated item.
Emails go into the case. Every case can have its own email address. Once you’ve turned it on with Copy in the case’s “Email it in” box, the emails you write from your case carry it in BCC. Emails you forward from your own sign-in address file themselves; anything else waits in Mail waiting until you check it.
Get an AI to help, if you want to. Copy a ready-made request into your own AI and bring the answer back. When it comes back as a letter draft, BuildMyEvidence checks its dates, amounts, item numbers and names against your record. There is no AI inside BuildMyEvidence.
One case file at the end. A cover, a one-page summary, the contents, then the record, numbered and dated, with every file at the back. The summary page also downloads on its own.
What it costs
Free to build. $59 once, when you want the finished file.
Building the record is free, for as long as you need it. So is reading every page of the case file, downloading any single file, and taking everything out: every file you’ve added, each with its fingerprint. You pay $59 once per case when you want to download the finished case file, the summary page or the itemized packs. No subscription. Nothing renews.
What it won’t do
It won’t tell you what happened, who’s right, or what to ask for. It doesn’t give legal advice. It keeps the record that anyone advising you would want to see.
Questions
- What's an explanation of benefits?
- It's the statement from your health plan showing what was billed, what the plan paid, and what it says you owe. Compare it with the bill line by line.
- The bill has gone to collections.
- See debt collection. The same record carries on.
- My plan refused to cover it.
- See health insurance denied.
