And based on a preliminary analysis of only the 2022 stand-alone Part D plans, we found that the national average 2022 Medicare Part D premium (not considering plan enrollment) increased from $41.38 in 2021 to $47.55 in 2022, supporting the CMS projection that the monthly Medicare Part D plan premiums would increase slightly as compared to 2021.
We also found that the national average monthly 2022 Medicare Part D premium, weighted by the number of people currently enrolled in each plan, will increase to $43.19 a 15% increase over the 2021 weighted monthly premium of $37.54
Bottom Line: This means that many current members of 2021 Part D plans can expect to see increases in their 2022 Part D plan premiums - unless they consider moving to a lower-premium 2022 Part D plan or Medicare Advantage plan.
