Creditable coverage rules decide what you tell Medicare-eligible employees.
The Medicare Part D rules require employers to tell people eligible for Medicare whether the plan’s drug coverage is creditable, meaning it is expected to pay at least as much as standard Part D coverage.
The Basics for Employers.
A plain-English summary. This is general information, not legal advice, and the rules change, so check the current text.
Annual Notice
Employers give Medicare-eligible participants a notice each year before Part D enrollment begins in the fall.
Disclosure to CMS
Employers also disclose the creditable coverage status to the Centers for Medicare and Medicaid Services each plan year.
Why It Matters
People who skip creditable coverage can face a late-enrollment penalty if they later join Part D.
How it plays out.
Creditable coverage rules ask a simple question: is the plan’s prescription drug coverage at least as good as the standard Medicare Part D benefit? The answer decides what the employer must tell Medicare-eligible people.
If coverage is creditable, a person who delays Part D will not face a late-enrollment penalty because of it. If it is not, the person should know that so they can decide whether to enroll in Part D.
Employers send a notice to Medicare-eligible participants each year before the Part D enrollment period begins, and also disclose to CMS. The carrier usually provides the determination for insured plans, and self-funded plans use a calculation or the simplified method.
