I'll put those links in my left pocket for safe keeping

Another thought that enters my mind...
If I remember correctly, I think these units technically fall under the category of DME (durable medical equipment) so maybe that in itself would not be considered as pre-existing.... The DME isn't a condition per se. The battery is a piece of equipment that needs maintenance.

I spose this could be looked at in several different ways.

This is something that could probably easily be looked into and maybe even the company (Medtronic) would advise on this.....or like Joan says, there might be some sort of legislation that has this covered.
