Medicare
In 2011, the Fund started incentivizing participation in Medicare Part B for eligible individuals by providing reimbursement of 75% of standard Medicare Part B premiums. Effective January 1, 2021, any retiree or dependent who participates in the Fund’s Medical Benefit Plan (MBP) and becomes eligible for Medicare Part B on or after that date is required to enroll in Medicare Part B. Reimbursement is provided by the Fund through P&A (a third-party organization) for the full monthly premium, i.e., standard premium, plus any Income-Related Monthly Adjustment Amount (IRMAA). Benefits are coordinated with those that are provided under the MBP.
