Anyones insurance NOT cover pens?

Not that relevant to me b/c I pump, but I was just looking at my prescription benefit info (for the fun of it, yes, i’m a health policy wonk) and I noticed that they don’t cover Lantus Solostar, only lantus vials as a tier 2, all other pens as tier 3, other than novolog, which is tier 2 as a pen and tier 1 for a vial. I’m just curious…is this a new trend in health insurance to screw the diabetics, or is it just my crappy student insurance that does this?
