I got my vest paid with private insurance company 5 yrs or so ago from American Biosystems, and they did all the filing for me. They would call monthly for a while to see if I was using it, and since I hated it with a passion, I would still get manual CPT from someone and only used it if I had to. So my "mileage" was very low, they would tell me to use it more. But I've now embraced the vest, use it more often than not. Since I'm working and active as a 23yr old, I'm trying to get the up-dated version (smaller lighter one that's 10 lbs, mine weighs about 50lbs+ and cant be taken anywhere) and the vest company said I would have to do the filing with the insurance company myself. They dont have the people to file for you anymore, unless you are already in the system and using the same insurance as before. This has been quite aggravating. We requested a case manager (for anyone filing with private insurance, its a good idea to have a case manager since everytime you speak to an ins. co. you talk to someone different. with a case manager one person deals with your case and has the power to approve something when the company would normally say no to. and if nothing else you dont have to explain the situation each and every time you call, the CM knows.) I wanted to let people know that ABS might require you to do all the dealing with the insurance companies now. Has anyone successfully gotten an up-dated version of the vest by filing private insurance?
