I have also tried with no success to get saline vials covered by Medicare. I have been given so many different answers by pharmacists, Lincare, Medicare, etc. One Medicare rep. that I spoke with on the phone last summer told me that it is covered under Part B, but in my area, only at Lincare and CVS. Pharmacists at both places told me that it is NOT. I tried calling Medicare again recently. The first person I spoke with tried to convince me that drugs are covered under Part D, not B! Unfortunately, their employees are not being trained. The next Medicare rep. I talked with was unsure, but did take the time to do some research and said that she thought it is covered. I have pretty much given up and use a GoodRx coupon. I purchased 180 vials of 7% saline for about $18. I will continue to follow replies to this issue to learn how others have succeeded. Donna
