Medicare Supplemental Plan

The State Health Plan Medicare Supplemental Plan works like a Medigap policy. It pays the part of Medicare-approved charges that Medicare does not. This includes deductibles and coinsurance. The Plan coordinates only with Medicare Parts A and B. It does not coordinate with Part C.


The Supplemental Plan does not pay for any services for which Medicare does not pay. Sometimes, providers who do not accept Medicare charge you more than what Medicare allows. If so, you will pay the difference under the Supplemental Plan.


Prescription drug coverage

Express Scripts is the pharmacy benefits manager. PEBA automatically enrolls all Medicare-eligible retirees and dependents into Express Scripts Medicare®. This is the State Health Plan’s Medicare Part D prescription drug program. PEBA offers this coverage whether you enroll in the Supplemental Plan. More information about Express Scripts Medicare is available in the Insurance Coverage for the Medicare-eligible Member handbook.



PEBA enrolls State Health Plan retirees automatically when they become eligible for Medicare due to age. You will receive a letter about your pending enrollment. You can still choose another health plan by responding within 30 days of eligibility.


If eligible, you can change to the Medicare Supplemental Plan during open enrollment. This takes place every year in October. Changes made during open enrollment become effective the following January 1. If you move out of the United States permanently you may be eligible to change to the Standard Plan.
