If you are insured, place a call to your insurance company, your Human Resources contact, or the Treatment Option you have selected and ask for their Insurance coordinator.

You need to insure that there are no questions unasked and that you fully and completely understand how much your insurance will pay, how much YOU will need to pay and you need to ask if you can get that in writing.
