It may sound counterintuitive that an individual health plan would pay for PrEP, but it looks like some men have found ways to make this work, as with this one story on Blogger from Minnesota.
Andrew Sullivan, in 2015, had written about the controversy over the “gay men’s Pill” here. It’s important to note that PrEP requires medical supervision and some blood work, especially for liver function.
Kaiser Health has a detailed posting about “tiers” of drugs for HIV infection and cancers, under Obamacare, from early 2016, here.
It’s pretty obvious that a “repeal” of Obamacare and a “replacement,” which would purport to separate pre-existing conditions into publicly funded mechanisms (mostly for the better for the general public), would put affordable access to both PrEP and probably protease inhibitors at risk, as they would seem to be related to “behavior”. “Moral hazard” will become a conservative and Trump-ian buzzword (and not just on Buzzfeed).
