If you are a state or California State University (CSU) retiree enrolled in a CalPERS Medicare health plan, you or your dependents may be entitled to a reimbursement if you pay above the standard Medicare Part B premium.

When your modified adjusted gross income, as reported on your IRS tax return, is above the set threshold established by the Centers for Medicare and Medicaid Services (CMS), you’ll pay the standard Medicare Part B premium amount, plus an additional income-related monthly adjustment amount (IRMAA).

What You Need to Know

Each year CMS announces the Medicare Part B premium. The 2024 Standard Medicare Part B premium amount is $174.70, up slightly from the 2023 premium of $164.90.

According to CMS, most Medicare beneficiaries will pay the standard Medicare Part B premium amount.

If you are required to pay an IRMAA, you will receive a notice from the Social Security Administration (SSA) advising you of your Medicare Part B premium cost for 2024, and how the cost was calculated.

CalPERS Will Automatically Reimburse You

If you or your dependents are eligible for Medicare Part B reimbursement, and are paying the standard Medicare Part B premium, CalPERS will automatically reimburse the eligible amount on your retiree warrant.

If you or your dependents are paying an increased Medicare Part B premium (IRMAA), you may be eligible for reimbursement of all or part of your Medicare Part B premium (some exceptions apply). The reimbursement amount is limited to the difference between your employer contribution and the cost of your plan’s premium, up to the amount of your Part B premium.

To understand IRMAA more, read our guide on Reimbursement of Premiums (PDF) available on the CalPERS website.

In December each year, CalPERS sends letters and emails to members currently receiving an IRMAA adjustment to their Part B premium reimbursement. The letters detail the standard Medicare Part B premium for 2024 and provide instructions for requesting additional reimbursement.

Requesting Additional Reimbursement

If you or your dependents are paying an increased Part B premium (IRMAA) and would like to request additional reimbursement, submit a copy of your entire SSA notice showing the IRMAA determination, MAGI, and increased Part B premium to CalPERS. Processing time for IRMAA documents is up to 60 calendar days, and you will receive a confirmation letter notifying you it has been processed.
