Creditable drug coverage is, on average, as good as or better than the basic Part D benefit. You should receive a notice from your employer or plan around September of each year, informing you if your drug coverage is creditable. If you have not received this notice, contact your human resources department, drug plan, or benefits manager. Be aware that this information may not come as a separate piece of mail; it can be included with other materials, such as a plan newsletter.

Several types of plans offer creditable drug coverage, including:

If you are considering delaying Part D enrollment because you already have prescription drug coverage, make sure to find out if your coverage is considered creditable. Maintaining enrollment in creditable drug coverage means you will not incur a late enrollment penalty (LEP) for delaying Part D enrollment. Additionally, having creditable coverage means that if you learn that you are going to lose such coverage and you want Part D coverage, you will have a two-month Special Enrollment Period (SEP) to enroll in a Part D plan.

If you have no drug coverage, or have drug coverage that is not creditable, Part D may help you. Even if you do not take prescription drugs, it is important to enroll in Part D so that if you later need to access prescriptions you do not face penalties or gaps in coverage.

Remember, if you decide to delay enrollment in any part of Medicare, keep a record of your insurance until you enroll in Medicare. You may need this documentation in order to sign up for Medicare later.
