Medco always shortchanged in the quantity while filling the prescriptions as ordered by the doctor but charged me the flat rate as set by my health insurance. For example, if my doctor ordered to check my sugar 6 times a day, i.e before and after each meal every day, thus amounting to 540 test strips for 90 days, medco will give me only 500 strips, thus cheating me of 40 strips.
BUT they charged me full amount of coinsurance as set by my health insurance for 90 days prescription. Thus they cheated me and my health insurance both.
It was very frustrating experience. Now I have a different pharmacy which is much better and accurate to follow my doctors orders.
