I'd really appreciate some help. At issue is a charge for nerve conduction tests.

I was originally quoted a fixed fee, which I paid upfront. After the tests were finished, the neurologist increased his fee without any advance notice. I protested, and involved my own GP as intermediary. He obtained an agreement for the neurologist to finish the tests/report for no extra payment.

However, the neurologist subsequently went back on this agreement and, several months later, sent me a new bill.

My GP is willing to support me in my contention that I should not have incurred any extra payments beyond that originally quoted and paid.

The amount involved is relatively small ($206), but I don't think I should have to pay it. The neurologist is threatening to go to a collections agency to enforce payment.

Any advice?

Thanks.

As long as you have that paper that says there are no additional fees, then you are all set. Let him send it to small claims court. The court will tell him he can't renig unless it is a charge not covered by the agreement or something in fine print. Look at the agreement, compare to the bill.

If there is a discrepancy you may be responsible for the payment.
