The accuracy with which they bill our insurance companies for each procedure performed is amazing! They are always very thorough when reviewing my account statement or invoices as well! I have yet been disappointed at any time from them regarding their service but that has never happened!! We use this software not only because it's so easy and efficient to keep up with all your medical bills (bills) but also due to its ability to be able to monitor how much we spend per month compared against what was billed through Medicare & Insurance carriers - therefore helping us save money.
