Your insurer’s statement of what was billed, allowed, and what you owe.
An EOB is not a bill. It is the insurer’s summary showing what the provider charged, what the plan allowed and paid, and what you may owe. Comparing it to the provider’s bill is the fastest way to catch errors.
“This is not a bill. Amount you may owe: $180.”
Upload your bill or EOB and Main AI checks it line by line, flagging where a charge or term like this may not be right.

“Billed $1,000 / Allowed $600 / Plan paid $480 / You owe $120.”
