PDP "Prior Authorization"

[steve960]

After enduring years of significant cost increases with AARP /UHC PDP, I am inclined to change to an alternative carrier for a significant cost savings. Reviewing the formulary of the new carrier prior to switching reveals the need for “Prior Authorization” before filling a tier 3 prescription. While this is not unexpected having experienced initial rejection and eventual approval at AARP /UHC, I am concerned that the “Authorization” criteria is likely to vary between carriers regardless of any published consensus guidelines. Should the prescription not gain Authorization then the out-of-pocket expenses would dwarf the potential savings. I am curious whether others have experienced failed Authorization for a medication previously Authorized by a former carrier? Without access to my medical record and prescribing physician, is there any way to verify Authorization before making the carrier switch?
