Complex Medicare enrollment rules and lack of notification cause tens of thousands of older adults and people with disabilities to face lifetime penalties, coverage gaps, and other harmful consequences. The Beneficiary Enrollment Notification and Eligibility Simplification (BENES) Act (S. 1280/H.R. 2477) would help people avoid making these costly errors by modernizing the Part B enrollment process. It would ensure that people approaching Medicare eligibility receive clear and timely information about Medicare Part B enrollment rules, simplify Part B enrollment periods, and improve transitions to Medicare by eliminating needless gaps in coverage.
