Since im sure there is a rule here against profanity, i will let you fill in the blanks of all the four-letter words i am thinking!! I have just had the rudest of awakenings…i got my Tandem t:slim x2 pump at the end of 2016 because i had met my deductible & max out of pocket due to a hosp admission. I stupidly thought my new insurer (FL Blue) would cover my pump & Dex supplies. Well, they do… AFTER i meet a $3,500 deductible. 
I gave myself intense training on all things Dex & pump last weekend after being quoted $735 for a transmitter & 8 sensors, and $1,461 for 4 boxes of pump cartridges & infusion sets. The inf sets are $270 per box of 10!! 
I shopped around & found “other brand” insets for $79.99-$109/box and as long as they have a luer lock, i am good to go. I experimented with refilling the same insulin cartridge & had no adverse effect so figure i might be able to get two infusion set changes from one cartridge.
This news is devastating to me! Does anyone have any ideas for those of us who are essentially paying out of pocket for these supplies despite a health insurance premium of over $700/month?
