CMS Deductible Change Benefit Mailings
Every year, the Centers for Medicare & Medicaid Services (CMS) updates coinsurance, copayments, and deductibles covered by Medicare. We’ll let you know what those changes are.
Creditable Coverage Letter
Creditable coverage means you have a health care plan that meets a minimum set of standards. Every year, this letter confirms that your plan meets the minimum standards for health coverage. If you want to change your plan, you should show this letter when choosing a new plan.
Explanation of Benefits (EOB)
This statement details what you have paid and describes the level of benefits you've used. It is not a bill. Review your EOB to make sure it is right. If you think there are errors, contact Customer Service. If you think you are the victim of fraud, report it immediately.
