The Medicare Premium Deduction Service is available to CalSTRS members currently enrolled in Medicare. The MPDS allows members to deduct their Medicare Part B premiums directly from their monthly benefit. This service is provided as a courtesy and there is no fee.

In some cases, it may be more convenient to pay your Medicare Premiums directly through CMS as third-party providers such as CalSTRS are limited to deducting only Medicare Part B premiums. CalSTRS is prohibited from deducting your Medicare Part A and D premiums. To learn more about CMS payment options visit Medicare.gov.
