Just reading the latest posts again on this and thought I should add additional commentary and the continuing saga on my part.
My local Walgreens told me in February (after uninterrupted Medicare coverage for the past 5 years) that Medicare only covers saline 7% from a particular manufacturer (Nephron) and they are back-ordered. After several months and attempts they are now saying that their wholesaler is no longer carrying this version.
I talked to Medicare DME rep and they had Walgreens Medicare on the line who said that in order to be covered it has to be prescribed with Albuterol or similar. Not true as it turned out. I had them re-run my saline and again it came up with the message 'NDC not covered'.
I called Medicare again and they told me something interesting. They claimed that they could not see a denial on their side and questioned that they even tried to file a claim.
I've given up with Walgreens at this point and am going to try and file a claim with Medicare. Also, I talked to Nephron and they claim they have no supply issues but refuse to tell me who carries it.
So many road blocks 🙁
