Sorry to hear about mom, but the Medicare publications are born at CMS and that is where you find the basic information that forms the foundation of your professional knowledge, not a forum. While every question is welcome in here, it is malpractice to run around in a professional capacity when you don't possess the basic rules of Medicare. There are some convoluted issues that trick us all up, but not the basics. Welcome of a great profession, take it serious and be professional and study like one.
Good luck to you and well wishes to mom.
