I finally found out my insurance plan (BCBS FEP 106) has retail and mail order different coverage. Retail (direct from CVS pharmacy) allows 15% discount on this prescription (Ceron) and $90 co-pay for mail order. The mail order prescription ordered by Mayo (Ceron) was out of stock at CVS Caremark and they contacted my Doctor for a replacement which he made (ZENPEP). This was in stock and cost $90 (co-pay) for 67 day supply (200 capsules)…. much cheaper than retail which I initially payed $190 for 90 capsules (one month)
I suggest everyone check their insurance coverage especially mail order prices….they are much cheaper!
Hope this helps.
