I was pre-approved, got the first bottle (only had to pay $5 with copay coupon), finished it, started the second bottle (again, $5 with copay coupon), and got both good and bad news within 2 days--I am cured!! But the next day I got a denial letter from my insurance company. How can they deny me since I am almost half way through the treatment? How can they reverse a pre-authorization once the treatment is under way? I still want to do the whole 12 weeks of the medication.
