Ling, Medicare paid almost entirely for my vest. The cost would have been $1895 but I ended up paying $222. The first time my doctor contacted a company that wanted me to sign a paper saying I would pay for the vest, about $1500/month for 18 months, if Medicare wouldn't cover it. I didn't want to potentially take on that amount of debt. My doctor contacted SmartVest and I was assured that I would not have to sign anything. They gave me the vest and Medicare paid for all but the $222.
