The Notice of Creditable Coverage (PDF 3 KB) confirms that existing drug coverage through the State Employees Group Insurance Program is as good as, or better than, prescription coverage through Medicare Part D. Members should not enroll in a Medicare Part D Plan unless they qualify for low-income/extra-help assistance under the Social Security Administration. Members with questions regarding the Notice of Creditable Coverage or other questions related to any Medicare issues should call the CMS Medicare Coordination of Benefits (COB) Unit at (800) 442-1300 or (217) 782-7007.
