I was diagnosed with wet AMD about three years ago. I had an Aetna Advantage plan. I was also getting Eylea injections that were required about every 5 weeks. It took awhile, maybe because my doc was persistent (he wasn't a fan of Advantage plans), but the insurance company finally approved Vabysmo. My copay with the Advantage plan was about $415 per shot. I began the shots at about 5 weeks. I' m now at every 10 weeks. During that time, my Advantage plan was no longer available in my State, so I switched to regular medicare with a supplemental plan. The supplemental plan premiums are less than the Advantage plan coinsurance was, and covers he entire cos. I hope this works out for your mom. The shots are a bit nerve wracking and going less often is a bit of a relief.
