One of my chemo meds was about to cost me thousands or at least many hundreds of bucks per month despite the best efforts of a devoted (a vet himself), highly experienced, full-time, professional pharmaceuticals procurer at my oncology clinic. It also required weeks to months of legal hoops and appeals just to get it approved from specialty pharmacies who deal only in such drugs.
Enter Tricare. A couple of phone calls from me directly to them got full approval for delivering that drug and two other specialty chemo drugs straight to my front door ... refrigerated ... for $20 apiece including drugs and shipping ... for a 90-day supply and plenty of 90-day refills @ $20 a pop.
The heck with CVS, Community/Walgreens, etc. If you don't have Medicare Part D (if you're eligible for Tricare, you don't want Part D), log onto or call ExpressScripts/Tricare at (877) 363-1303. It's one of the few instances in which our veterans medical benefits actually pay off as promised.
