There are a few physicians who are not on your system ie their billing numbers ... is there a way to access this on your end. or do i need to ask them to get it.

Hi,

The referring physician list is compiled from users like yourself and when hospitals provide us their database. We update it every year.

If you can´t find the billing number, please obtain it from the referring physician and feel free to enter it.

Thanks.
