Thanks Sue. I don't know if this is considered a "high frequency chest oscillation device" or not, since I am not very familiar with the device but I would think for it to work on secretions it would have to be, but according to the cms.gov website if it is, if you meet one of three criterion (i.e. CF, Bronchietasis (with qualifiers), or a host of neuromuscular disease diagnoses, AND have a well documented failure of standard treatments to adequately mobilize retained secretions, it should be covered by Medicare. I may be misreading something as I am not very familiar with this sort of thing and would love it someone would set me straight on where my thinking is incorrect. I will have to say, I was surprised that it might not be covered. I am wondering now if the Smart Vest and other similar devices are covered by Medicare. Anyone know from experience?
