Can my doctor charge me more for services already paid for?
I went to my doctor for a routine check-up and they recommended getting X-rays. I asked the cost and they quoted the total visit between $280 and $340 depending on how many x-rays. I agreed, received the service, then went to reception to pay my bill.
I notified them I don't have insurance and am paying the bill in full (because it's easier than EOBs or worrying about approvals). They gave me the bill and I asked if it was the full bill, they confirmed. A month later they reached out saying I have an overdue balance and when I asked for the itemized receipt they added new amounts totaling $400 as the new charge. The charges sound like what I agreed to, but the accounting amounts don't add up to the overdue balance (i.e. charges are $31 + $31 but overdue amount is $46). When I call they don't answer.
Is it legal for the doctor's office to change the price retroactively after I already paid? What can I request from them to try and sort out when and how the charges were applied? Thank you!
