The only pharmacy in my area that claims they can get sodium chloride 3% does not accept coupons but will bill medicare. However, they claim that medicare part b will only cover sodium chloride 3% if mixed with something else. I called Medicare and they can't find it on the list of covered meds but she said she doesn't have the complete list so my doctor should call the medicare provider line etc. Can anyone help with the exact words to use with the pharmacy? Thanks (I have been on the phone trying to get the drug for weeks)
