You got a surgery bill
One operation produces several separate bills from several separate businesses, and they arrive weeks apart. That fragmentation is where the errors hide.
Wait for all of them before paying any of them
The hospital, the surgeon, the anesthesiologist, pathology and any assistant surgeon each bill separately. Paying the first one that arrives removes your leverage on the rest.
Check the anesthesia math
Anesthesia is not a flat fee. It is base units plus time units multiplied by a conversion factor, and every part of that is checkable against the record of how long you were actually under.
Look for charges that were never estimated
If you were given a good faith estimate and a provider on it is billing you more, or a provider who was never on it is billing you at all, that is a specific and disputable problem.
Verify you were charged for one of each thing
Duplicate line items, supplies billed separately when they are already in the facility fee, and recovery room time that overlaps the operating room time are all routine findings.

Why did I get four bills for one surgery?
Because the hospital, the surgeon, the anesthesiologist and pathology are usually separate businesses that each bill independently. It is normal, and it is also why totals are so hard to check.
The assistant surgeon billed me and I never met them.
That happens, and it is worth challenging. An assistant surgeon charge should be supported by the operative report. If the report does not document their involvement, the charge should not stand.
Can I dispute a bill I already paid?
Often yes. If you were overcharged and can show it, a refund is possible, though it is harder work than catching it before payment.
Rather not do this yourself?
Send us the bill and our investigator works the case for you: the itemized request, the line-by-line audit, and the calls with the billing office.
