Missing an Enrollment Period Can Matter

Delaying Enrollment May Cause Problems

Depending on your circumstances, delaying enrollment can result in:

  • Part B late-enrollment penalties
  • Part D late-enrollment penalties
  • Delays before coverage begins
  • Gaps in medical or prescription coverage

Special Enrollment Periods Are Event-Specific

A move, loss of coverage, change in Medicaid or Extra Help, plan termination, or another qualifying event may create a Special Enrollment Period.

Employer-related Part B enrollment periods and Medicare Advantage or Part D Special Enrollment Periods have different rules and deadlines.
