Is there somewhere where i can find out what is covered and what is not...I had bought a bunch of supplies like BM storage bags, spare parts accessory kit and the labeling system with lids and the only thing that was covered was the spare parts kit but everywhere online it says anything that 'assists in lactation/breastfeeding' is covered....im confused...there has to be a list somehwhere, how do they know what to cover and what to deny?
