Buddy for medical bills
Send me the bill and the explanation of benefits. I’ll line them up, show you where they don’t match, and write down what to ask before you pay.
A son in Bellingham, Washington, with his mom’s mail spread across his desk at lunch.
Buddy made the photos of the bill and the explanation of benefits in this conversation to stand in for the ones a person would send. The hospital is made up.

Send me the bill and the explanation of benefits. I’ll line them up, show you where they don’t match, and write down what to ask before you pay.
From two envelopes to four questions
Send both papers
Photos or PDFs of the bill and the explanation of benefits. If a page is hard to read, I’ll ask for a clearer copy.
I line them up
Each charge on the bill sits next to what the EOB says about it, and anything that shows up on one and not the other gets called out.
You make the call
I write down the questions. Whether a charge is right is for the billing office and the insurer to answer, and what you pay is your decision.
More you can ask for
- Here’s Mom’s bill and her explanation of benefits. Does anything look off?

What you get back
Where they don’t match
Charges on one paper and not the other, amounts that differ, and claims still marked pending. I tell you what each page says, not which one is right.
Work with filesQuestions to ask
A one-page list with each charge and the question that goes with it, to keep in front of you on the call.
A record of the year
Ask for a spreadsheet of this year’s bills with dates, amounts, and what’s been paid, and a new copy when another bill comes.
Working with dataA note you decide to send

Questions people ask
Will Buddy tell me if a bill is wrong?
No. Buddy reads the bill and the explanation of benefits, tells you what each one says, and lists where they don’t match. He isn’t an insurer or a billing advocate. The billing office and the insurer are the ones who can say whether a charge is right.
Can he contact the billing office for me?
He can draft the letter or email. Sending it to someone else needs a connected email app and a request from you.
What if he reads a number wrong?
Check the amounts against the papers before you call or pay. If a page is blurry or cut off, ask Buddy which part he couldn’t read and send a clearer copy.
