Just put on their bill that the payment is due in 30 days (standard) after that in incurs a 10% late fee.

Found with my eye surgeries they ALWAYS charge the patient 5% over what insurance will pay and make the excuse that you must not have met your deductible. To me that is just plain robbery. My insurance has a deductable on meds, but not procedures. I wait till they threaten to send the bill to collections then tell them I am happy to send them information that I don't have a deductible on procedures and they drop the charges.
