CID said Medtronic. Caller asked if I was still having trouble with my back and my knee and said my PCP had ordered a back brace and a knee brace and they were free via Medicare. Asked if I had my Red White Blue Medicare card. I don\'t use , that card anymore, I use the card from the insurance company. Also said I\'d seen my PCP 4 months ago, but I have no record of that appointment. Very suspicious.
