The Aetna 2025 formularies are available. I used View Aetna Medicare Coverage & Benefits | Aetna Medicare to get to them. Looks like they have at least 2 Silverscript formularies for 2025 depending on what state you are in. I checked the one for California and the insulin list says to me “T1D go away”. I hope you don’t have too much trouble finding a different plan that works for you.
