Hi George,
Much depends upon what your doc told you about insurance coverage.
IF you were told Medicare and your supplement would cover the cost AND the doc did not tell you you might be liable for a part of the cost you cannot be held responsible.
A few years ago I was on an Amifostine trial. Was told medicare & BCBS would cover all costs. It didn’t. Medicare sent a letter to my doc telling him there was no coverage. Further, sinice I was not told I might have to cough up the cost, the doc could not bill me.
After all was said & done the producer of the drug picked up the tab—for 6 of us.
A possibel problem with your situation is Vidaza is FDA approved. It is no longer provided on a trial basis. What are the implications? If you doc has stated insurance will cover it, would be inclined to go with his adcvice. To be perfectly safe would call Medicare and and your supplement ( if you have drug coverage) to be clear. Would also want it in writing.
