Sorted by monthly premium. The lowest premium isn't always the lowest total cost: drug costs, copays and the out-of-pocket maximum matter too.
Plan costs and benefits are from CMS's 2027 Medicare plan data (data as of October 27, 2026). Star ratings are CMS's 2027 Star Ratings. Every year, Medicare evaluates plans based on a 5-star rating system. Benefits, premiums and copays can change from year to year; check the plan's Evidence of Coverage, call the plan, or use Medicare.gov before you enroll.
