I've had Humana Mail order pharmacy for several years and have to echo the comments about slow service and unexplained cancellations (with no customer notification), delays due to miscommunication with Dr's office, and delays due to re-repeating the prior authorization process at the last moment, and delays in not noting that refills have already been approved. As noted elsewhere, the problem seems to arise with certain medications which then evidently throws their process into chaos. Routine medications are handled more smoothly in my experience. On the telephone staff are very pleasant, take notes, make internal calls and give assurances which often don't hold up. This year the feds are evidently allowing dispensing of only 30 rather than 90 day supplies of certain meds meaning the hassle is now becomes monthly rather than quarterly. I'll drop Humana as soon as an alternative is identified, even if more expensive. Probably easier to just pick up an Rx from the corner drugstore.
