Get your mind outta the gutter! We need a sticky on the INR machine process. I know it varies with insurance, but I mean with just the basics...like links to all the providers, QAS, Raytel, Phillips....like that. Links to the sites where one can buy a machine for cash. Names of companies that give a discount if paying for cash. The fact that one needs a script or a page filled out by the doctor (my insur. called it a letter of medical neccessity.)
