OptumRx Mail Order part of United Health Group. UHG is my prescription insurer, they set our policy to favor OptumRx mail-order for 90-day supply vs the retail pharmacy (like Walgreens). OptumRx does NOT accept manufacturer coupons. For Tier 1 and Tier 2 drugs, Optum charges hundreds of dollars. While when I go to Walgreens with the manufacturer coupon, I pay $0 at Walgreens vs $222 at Optum! Another drug, I pay at Walgreens a 1/3rd of what Optum charges for the same drug! In other instances, I have found that I over-pay at Optum when I order 90-days by mail vs when I can find pen needles at online stores (with the same prescription) at a fraction of the price. We have other drugs where Optum and UHG pay $0 towards the drug and charge us the co-payment which is the actual cost of the drug. I see alot of price-fixing taking place at Optum. And don't try calling their customer care, they don't care.
