Missing Medicare enrollment deadlines imposes a permanent 30% surcharge on the $202.90 Part B premium, recalculated annually.
Missing Medicare’s Initial or Special Enrollment Period results in a lifelong 30% surcharge on the $202.90 monthly Part B premium. The penalty is recalculated each year as premiums rise, compounding long-term costs for enrollees.
The surcharge applies when individuals fail to enroll during their seven-month Initial Enrollment Period or an eight-month Special Enrollment Period after employer coverage ends. COBRA or retiree plans do not qualify as exempt coverage, leaving gaps that trigger penalties.
For workers at firms with fewer than 20 employees, Medicare becomes the primary payer at age 65. Delaying Part B enrollment risks both the penalty and uncovered medical expenses, with no relief for late sign-ups.
