Don't bank on it.

I enrolled in Humana Medicare part d in 2018. 2018 premium was $20.40 per month. In 2019 it increased to $28.60 a month. For 2020 they switched me to a plan that is $57.30 even though they introduced a new lower cost plan. All the while this was going on, they kept trying to get me to enroll in one of their Medicare Advantage plans. You know, those "Simon says" not in network plans that leave you high and dry with big bills unpaid. This year I terminated Humana. Your just a "lead" for them when you enroll in Humana. The pharmacy isn't bad but the premium hikes are ridiculous.
