Notify MCERA if Your Medicare Part B Premium Increased

Take a close look at your Medicare Part B and/or Social Security statements and any letters you received from Medicare or Social Security.

If your Medicare Part B premium is paid through your Social Security benefit you may not have seen a change in your net benefit because, for many people, Social Security increased benefits at the same rate they increased Medicare Part B premiums. Even if your net Social Security benefit is the same, the amount being deducted for Medicare may be different in 2017.

Please note that your monthly MCERA Deposit Confirmation only shows your current amount of reimbursement. It does not reflect the actual premium you owe for Medicare Part B.

Send MCERA documentation from Social Security or Medicare that shows what your Medicare Part B premium was in December 2016 and how it changed starting January 2017. This can be a letter notifying you of the change in premium, Medicare billing statements, or Social Security pay stubs.

Mail the information to: MCERA, One McInnis Parkway, Suite 100, San Rafael CA 94903.
Fax the information to: (415) 473-3612.
Email the scanned information to: MCERARetirees@marincounty.org.

If your Medicare Part B premium is paid through your Social Security benefit you can request a Benefit Verification Letter from Social Security.
