I read something similar some time ago and that's what I do..........
but.........I wonder if it really will work when the time comes.........
1) The bus system in Honolulu gives a big discount if you show a Medicare care but they won't if you show a copy even w/ all the numbers.
2) I used to have the impression that a power of attorney would solve a host
of problems (not related to this subject) but the real world is different and I find that many (most?) institutions require the POA to be on their form or that you fill out an affidavit (their form) swearing that the POA is real.
Anyone have any real world experience w/ Medicare providers?
