Stand-alone prescription drug plans (see chart below) are normally for those who do not enroll in a Medicare Advantage Plan. That includes those who elect to use Original Medicare, with or without a Medigap Policy, or who select a Contra Costa Health Plan. Plans must conform to standards set forth by the Center for Medicare and Medicaid Services but are sold by private insurance companies.

Remember, every year during Open Enrollment (Oct. 15 – Dec. 7) you can change stand-alone prescription drug plans or Medicare Advantage plans for the following year as well as enroll in one for the first time. If you do not enroll in a Part D plan on a timely basis and do not have other creditable drug coverage you may be subject to a late enrollment penalty.

For those with low incomes and resources, Extra Help is available for your Part D. Click here to learn more about Extra Help.
