I have Humana for part D. They covered it this year although it's not formulary of course. My pulmonologist must have applied for a formulary exception, and I had to pay the part D cap the first month I was on it. Now I'm worrying about 2027, because my pulmonologist is on an extended maternity leave. I will have to apply for the formulary exception myself. I responded to my Medicare ins agent's email request to fill out the form for part D (RX list) she needs and I hope she will help me before the deadline, but the agency has already warned that they are prioritizing people who are losing Advantage Coverage in our area, so I'll be later on the list to have a meeting. I guess meanwhile I will call Humana.
