Who actually decides this
Not the logo on your card, most of the time. Three parties sit between you and the answer, and knowing which one is saying no tells you who to ask.

The pharmacy benefit manager · CVS Caremark
Aetna hands its formulary to CVS Caremark, so what is preferred, excluded or subject to step therapy is CVS Caremark’s decision rather than Aetna’s. When you read that a formulary changed, this is the company that changed it.

Your employer, if the plan comes through work
Weight-loss drugs are usually a category an employer buys or declines, not something the insurer includes by default. That is why two people holding identical cards get opposite answers, and why the useful question for member services is whether your plan includes the weight-loss medication benefit at all, before anything about criteria.
Get your real answer
Have your prescriber submit the Aetna/Caremark prior auth with your type 2 diabetes diagnosis and metformin history documented, then confirm your tier price with caremark.com's "Check Drug Cost & Coverage" tool.
Coverage is plan-specific: this page reports what Aetna publishes, not a promise about your plan. Not medical or insurance advice.
