Hawaii Employer-Union Health Benefits Trust Fund

If you were hired before July 1, 2023, and are notified by Medicare that your Medicare Part B premium will have an income-related monthly adjustment amount (IRMAA), in other words your Medicare Part B premium is higher than the standard rate due to your higher income level, you will be reimbursed the higher amount. However, you MUST promptly (within two years) send the EUTF a copy of the letter from the Social Security Administration informing you of the higher Medicare premium. If you were hired on or after July 1, 2023, the EUTF will reimburse you the standard Medicare rate, but not IRMAA.

EUTF automatically resets your Medicare Part B reimbursement to the Medicare standard rate every January 1st. Every year Medicare reviews your income and sets your Medicare Part B premium accordingly, so every year, you must notify EUTF of your higher than standard Medicare Part B premium in order to receive the full reimbursement.
