Comment It's called an inducement outlawed by Medicare (Score 1) 68
But the company has a program that lets me get it for $10/month, but ONLY if I have private insurance (so that they get the insurance company's share of the payment but not mine, basically). It doesn't work with government insurance for some reason which I won't care about until I turn 65 later this year. But the drug company basically sets the price to some level that gets them hundreds of dollars per month, whether I'm paying it or the insurance company is paying. The drug company takes in over $10 billion per year for this drug, last time I checked, so they're probably covering their costs OK.
It's called inducement. To expound on your case for everyone else: the drug company is basically giving you a huge rebate for your portion of the cost so it can charge the insurance company the huge remaining cost. Say your drug costs $600/month. You have a drug copay of $200/month, the insurance company might have a negotiated rate of $450. So it pays $250 of it and you're on the hook for $200. The drug company knows that's a lot of money and a lot of people would balk at paying that. So the drug company says "hey, no sweat, we're nice guys concerned about you, so we'll writeoff $190 (which they would not have gotten anyway), you pay $10, and we'll still get $250 from your insurance." Not a bad gig if you can swing it.
BUT BUT BUT now to the part you're uncertain about: why only for private insurance and government insurance, like Medicare?
It's because Medicare has an Anti-Kickback Statute [42 U.S.C. 1320a-7b(b)]. And it is EXTREMELY broad. Pretty much no form of remuneration can be used as inducement to use anything Medicare pays for.
