I do not understand why you are not able to use it. Are you putting in Goodrx.com. They ask no questions, just put your zip code and med, then the prices come up. I have a plan G , plus a supplement and my own drug plan from another company, not affiliated with Medicare. If you have Medicare Advantage it may not work. At the end of their documents it gives the coverage. All insurance plus Medicare. There is no income questions. Maybe call them to get the answers. I am not giving you false information.
