I can confirm that they are already covered by major insurance plans, but the premise of this question is somewhat flawed.

Large insurance companies are offering plans that cover drugs as specified in your criteria, and have been doing so for some time already. However, each company offers multiple plans under their brand, which may have different formularies and copay/coinsurance percentages. The different plans can also be contracted with different PBMs. In short, it is possible for the criteria to be met and not met at the same time. Coverage can also depend on the network of the providing pharmacy.

Anyway, if you needed proof to resolve yes, here is my plan's formulary (Anthem). Tier 2 is a $30 copay for 30 days, or $60 for 90 days in network, 50% OON. Tier 3 is $50 and $100. NC is not covered. S is specialty, 30% with a cap of $150

Some plans are definitely more flexible than others, though, and approvals can be hit or miss. If anyone is considering using insurance for weight loss meds, I’d recommend checking your policy’s fine print (and maybe preparing for some back-and-forth with customer service).

I will be very embarrassed if a large insurance company is already doing this.
