• A child who is an eligible dependent of an employee in the PEBB Program and a school employee in the SEBB Program may only be enrolled as a dependent under one parent in either the PEBB or SEBB Program. C. Medicare Eligibility and Enrollment. 1. Employee and dependent If an employee or their dependent becomes eligible for Medicare, they should contact the Social Security Administration to ask about the advantages of immediate or deferred Medicare enrollment. An employee or their dependent are deemed eligible for Medicare when they have the option to receive Part A Medicare benefits. If an employee or their dependent chooses to enroll in Medicare Part A, Medicare regulations and guidelines will determine whether Medicare is the primary or secondary payer. An employee or their dependent who is enrolled in Medicare may remain enrolled in PEBB medical coverage. However, an employee may choose to waive their PEBB medical plan or remove their dependent from their PEBB medical plan and choose Medicare as their primary insurer. If an employee does so, neither the employee nor their dependent can enroll in PEBB medical except during the annual open enrollment or a special open enrollment. In most situations, an employee and their dependent can elect to defer Medicare Part B enrollment without a penalty while enrolled in PEBB medical coverage. When the employee terminates employment, the employee and the dependent can enroll in Medicare Part B during a Special Enrollment Period. If Medicare eligibility is due to disability, the employee or their dependent must contact the Social Security Administration about deferring enrollment in Medicare Part B. Upon retirement, Medicare will become the primary insurance payer, and the PEBB medical plan will become secondary. See “PEBB retiree insurance coverage.” 2. Continuation coverage subscriber, a retired employee of a former employer group, or their dependent If a continuation coverage subscriber, a retired employee of a former employer group, or their dependent becomes eligible for Medicare, federal regulations allow enrollment in Medicare three months before they turn age 65. If they do not enroll within three months before the month they turn age 65, enrollment in Medicare may be delayed. If enrollment in Medicare does not occur when the subscriber or their dependent is first eligible, a late enrollment penalty may apply. D. When Medical Coverage Begins. 1. Employees and dependents For a newly eligible employee and their eligible dependents, medical coverage begins the first day of the month following the date the employee becomes eligible. If the employee becomes eligible on the first working day of the month, then coverage begins on that date. If the eligible employee is a faculty member hired on a quarter-to-quarter or semester-to-semester basis, medical coverage begins the first day of the month following the beginning of the second consecutive quarter or semester. If the first day of the second consecutive quarter or semester is the first working day of the month, medical coverage begins on that day. For an employee regaining eligibility, including following a period of leave or after being between periods of leave described in PEBB Program rules, and their eligible dependents, medical coverage begins the first day of the month the employee is in pay status eight or mor hours. If the employee is a faculty member regaining eligibility no later than the 12th month after the month in which they lost eligibility for the employer contribution toward PEBB benefits, medical coverage begins the first day of the month in which the quarter or semester begins. Note: When an employee who is called to active duty in the uniformed services under the Uniformed Services Employment and Reemployment Rights Act (USERRA) loses eligibility for the employer contribution toward PEBB benefits, they regain eligibility for the employer contribution toward PEBB PEBB HMOHSA 2024 52
