[EMPLOYEE_FIRST_NAME], We're writing to inform you that one of your dependents has aged out of our company's health benefits plan. This means they will no longer be covered under your plan, and you will see a reduction in the amount deducted from your regular paycheck. If this is a mistake, please let us know as soon as possible and provide any necessary documentation. If you have any questions about this change or need assistance finding alternative coverage for your dependent, please don't hesitate to contact your supervisor or HR. Thank you for your attention to this matter. Thank you, The [EMPLOYER_NAME] Leadership team
