Hi Sal14
I'm a guy. I got Evenity covered. I have traditional medicare and medicare supplemental, they covered after the fact. I also got it covered thru Amgen Safety Net. All of that seemed unlikely for a long time. It took 5 months. My case was complicated due to the insurance person at the doctor's office going on sick leave just after they started trying to get approval for it.
After many frustrations and few replies from the doctors office I tried switching doctors. They agreed to try to get me Evenity but had their doubts about success. Eventually I realized their insurance person was reluctant to fight for it. By this time I had submitted the forms and whatever to apply for help with Amgen Safety Net.
Finally they hired a new insurance person at my original doctors office. So, I went back to the original docs office. The new insurance person was a go getter. She had multiple phone calls to Medicare and said she got both yes's and no's depending on which rep she talked to.
Then Safety Net came thru and I started Evenity. Then the doctors office submitted to Medicare and Medicare paid.

Here's how I think it works at Medicare. Medicare will give pre-approval (in writing I think) for some drugs for some conditions like say cancer drugs. I think they do not do an official pre-approval for osteoporosis drugs. They may say yes or no on the phone but that seems to not be a guarantee like you could get for drugs for some other conditions. So I had a definite yes from Amgen Safety Net and the doctor started giving me the drug. Then they submitted to medicare after the first treatment and lo and behold Medicare did cover it and of course that meant the supplemental would and did cover it also.
This is my best understanding of what happened for me. It may not all be correct as I couldn't see behind the scenes at the two doctor's offices and I never found a definitive source on Medicare and osteoporosis drugs. If someone knows more about how this works I'd love to hear about it.

On I had a bad T-Score with a worst of -4.1 in the spine. I had no prior fragility fractures. I'm not sure what else the doctor's office would have put on my Medicare requests.
Evenity has worked great for me. At 10 months I had a 30% improvement in my spine and a small improvement in my hips. I couldn't believe the spine density increase!
Hope this helps and good luck to you and your husband.
