What changes from 2026 to 2027?

The changed lines are marked and come first. In-network amounts; members keep paying the Part B premium unless the plan reduces it. Where the plan files different amounts for parts of its area, the premium and limit show their range (your county's are in the table below). The plan files its benefits in parts for different counties, so lines marked ◆ show the most generous part of its area and some counties get less: the plan's Evidence of Coverage gives your county's amounts.
