Pharmacy's can get in trouble with the drug plan carriers for doing that in most states. They are not allowed via their carrier agreement to advise customers of a lower price by paying cash, using coupon, etc.
That may change soon but AFAIK it hasn't changed yet.
I had a SilverScript problem last year. Mcare showed a particular drug (don't recall which) as tier 2 generic, no deductible. Client filled Rx in January and had to pay around $100. Checking with SS discovered it was actually tier 3 and subject to their new (2019) $100 deductible.
As indicated before, Mcare effectively showed a lower price than SS online. I was told that SS changed their pricing internally the end of Sept or first part of Oct for AEP. Was also told that Mcare updated their information in August so they "missed" the last update.
Unless I have missed it there are no disclaimers on pricing on the Mcare site.
Bottom line, you cannot and should not promise or guarantee any pricing report shared with clients . . . unless you like dealing with angry clients.
That being said, even if you took the time to run reports on carrier sites if tiers/pricing changes AFTER the report is run you are still in the same boat.
I give clients the copay run but also tell them to check with the carrier for current pricing.
That's about all you can do.
I’ve been told numerous times that they pay no more than the tier copay. If the drug cost less then they pay less.
I’d have to do some research but I have trained by Ins companies that it’s the way it is
I’ve never guaranteed any pricing, other than, “you can pay up to this amount for each tier”. No one in their right mind would guarantee the Medicare.gov copays
