In the state of la there is no state tax on prescription drugs, but local municiplaties can charge a tax. The local tax in pineville, la is 5%. Cvs adds the tax to your insurance co-pay where it does not show up on the receipt. When you ask why your co-pay is more than it should be, you are told that your insurance company tells them what to charge. Nothing is mentioned about tax being added to the co-pay. I feel this is an underhanded way of charging the tax without the consumer knowing they are being charged. I asked my insurance company why the co-pay was more than it should have been and they researched it and told me about the tax. When I called the pineville cvs, the pharmacy manager first denied that the tax was being charged, then said she knew it was being charged and the computer program was supposed to be corrected where it was not charged, told me she would refund the tax charged; when I came tot he pharmacy requesting the refund, she called her district manager, and said I would have to go through him. Also, cvs charges tax on the total cost of the drug, not just the co-pay amount. This resulted in my paying $12 in tax on a $30 prescription co-pay. Cvs says the insurance company should pay tax on their portion, but if they don't they just charge the consumer. I finally after a month was able to get a phone number for cvs corporate. They said the district manager would arrange to refund the tax. He refused. When I reported this to cvs corporate, he was forced to give me a cvs gift card in the amount of the refund. Other pharmacies in our area do not tax the drug if you have an insurance co-pay. I can only speculate that the pharmacists get a bonus based on the amount of drugs they sell, since the pharmacy manager kept saying "but that will come out of our money" if they had to give me a refund. Maybe if the companies would quit creating incentive programs that encourage their employees to short-change or rip off the consumer, maybe stuff like this would stop.
