Caller ID came up BCBSM and you get a nice pitch about "free in home health screening, which they will share with your primary care provider". Somehow they even have that information (although they gave the wrong name in our case). They convincingly make it sound like they are somehow affiliated with whoever your health insurance provider is, but it's just a way to get in the door and charge off for medical services. The callback number that they give is 888-306-0615, which rings back to MedX
