Guides / Medical bills
Read the itemised bill first
The one-line summary is not a bill. Ask for the itemised version, then check these six things.
Never pay a hospital bill you have not seen itemised. The summary exists to be paid without questions.
Ask for it, in these words
"Please send me a fully itemised bill with CPT and revenue codes for every line."
You are entitled to know what you are being charged for. The itemised version is what shows the duplicate charge, the drug you refused, the room you were in for four hours billed as a day.
A price is not a fixed fact
The same brain MRI at the same hospital, priced two ways: what a self-payer is asked, against what an insurer typically pays there. At Great Falls Clinic that is $2,646 against $461. 6 of these 7 hospitals ask a self-payer more than the typical insurer rate. That gap is what you are negotiating against.

Six things to check
1. Dates. Charges dated before you arrived or after you left. It happens more than it should.
2. Duplicates. The same test billed twice, or a panel billed alongside its own components.
3. Quantities. Supplies and medication counts. A quantity of 10 where it should read 1 is a common data-entry error and rarely gets caught by anyone but the patient.
4. Things that did not happen. Medication you declined, a consult you never had, a service cancelled on the day.
5. Room and time. Observation billed as inpatient. Hours billed as a full day.
6. Bundling. Items that should be part of a procedure billed separately on top of it.
The call
Be calm and specific. Vague dissatisfaction gets a payment plan. A line number and a question gets a review.
"Line 14 shows two of the same test on the same day. Can you tell me what the second one was for?"
Ask for the name of the person you spoke to and a reference number. Follow up by email so there is a written trail.
If a charge is removed, ask for a corrected itemised bill rather than a verbal assurance.
Before you agree to a payment plan
A payment plan is an agreement to pay the full amount. Check financial assistance first, because the bill may not need paying at all. Once you are on a plan, the conversation is much harder to reopen.

Who publishes this. CoreMed Healthcare is a Montana healthcare membership company. We publish these guides because we think the information should be easy to find, and because our own members need it. They are written to answer your question rather than to sell you a membership: where the right answer is a hospital charity care programme or a different kind of plan, that is what they say. Nothing here is legal, tax or medical advice.
Common questions
Am I entitled to an itemised bill?
Ask for one and you will be given one. It is a normal request and billing departments handle it constantly.
Should I pay while I am disputing it?
Ask for the account to be held during a review or a financial assistance application, and get that confirmation in writing.
Is it worth doing for a small bill?
Errors are proportionally just as common on small bills. Whether it is worth your afternoon is your call.
Do I need a professional?
Usually not for a single bill. For a long hospital stay with thousands of lines, a medical billing advocate can be worth it.

Hospital charity care in Montana
Most Montana hospitals are legally required to have a programme that can reduce your bill to nothing. Hardly anyone knows to ask.
Getting a price before you are treated
If you are paying cash, you have a legal right to a written price before scheduled care. Most people never ask for it.
Surprise bills and balance billing
Some bills you are simply not allowed to be sent. Knowing which ones is worth real money.
