Is this extortion? Blue Cross Blue Shield refuses to send my med home, unless....

So I've been taking Tezspire since the pandemic for Severe Asthma. Tezspire it's an injection that lowers Interlukant 8 and 13 and I have to take it every 28 days just to stay alive. The problem is that I have to travel more than hour just to get the med injected on my shoulder. The whole thing takes less than 5 minutes. In the last 6 months, my condition got worse. I've been going to the emergency room a lot for shortness of breath and tachycardia. Fatigue is insane, sometimes it's hard to walk around the house. Symptoms show up randomly and it happens every single day 😔 These symptoms make me anxious and honestly it's really hard to travel when you can have an "episode" at anytime, especially when it's more than an hour away. I talked to Blue Cross Blue Shield and they said that they'll do it, if I stop going to the emergency room. I was like what?! You want me to stop going to ER And they said yes If you don't go, for at least 3 to 4 months will send your med home. The best I did was 30 days, but unfortunately last week I had to go bc it was just unbearable and I was alone at home. Is what their doing ok or legal? I feel like this is some form of extortion.
