Thanks for the info. It explains why the Rapid Antigen test is not covered by insurance but it does not explain why it is so difficult to book this option on the CVS website In my case, although I have health insurance coverage in the US, I am willing to pay for a Rapid Antigen test because I find this option faster and more convenient (and also cheaper than a PCR test). But I noticed that on the CVS website, whether or not you answer yes to the question asking if you have insurance, it doesn't offer you the choice of the rapid antigen test. Only when one answers yes to the question you listed above ("Are you seeking a covid-19 test because of high transmission rates..."), it proposes the rapid antigen test. This does not make sense to me.
