I went on medicare in December 2018. I have the Prescription plan part D with Envision. During 2018, up until December, I had a high deductible policy through my former employer. I take atorvastatin. 4 times I got 90 day refills on the atorvastatin in 2018 – once in AZ and 3 times in MI. Each time the charge to me was zero. I did not meet my deductible at any time during the year. I understood that there were certain common drugs that patients were not charged for and thought my insurance was immaterial to the transaction. Today I refilled the script for the first time since going on medicare and was charged $20 by Walgreens in FL. I questioned the tech but he did not have a clue. Checking the Envision website it verifies that the $20 is what I would be charged. If I had went to CVS the cost would have been $2. CVS is in my future. In MI Meijer does not charge for atorvastatin – maybe Walgreens was price matching there? Meijer is not in AZ though. I am confused – anyone have an idea what happened to my free drug?
