How old are you? I am on medicare and could get coverage for Tymlos under a Plan D prescription plan. Since the changes under Biden you pay out $2000 max and then all prescription costs are covered. But Tymlos must be listed on your plan's "forumulary" and only two cover it: One is United Health Care and they are more reliable than the other. I pay 86.50 a month for this Plan D. After I spent $2,000 my Tymlos was free.
