Consider all your drug coverage choices
Before you make a decision, learn how prescription drug coverage works with your other drug coverage. For example, you may have drug coverage from an employer or union, TRICARE, the Department of Veterans Affairs (VA), the Indian Health Service, or a Medicare Supplement Insurance (Medigap) policy. Compare your current coverage to Medicare drug coverage. The drug coverage you already have may change because of Medicare drug coverage, so consider all your coverage options.
If you have (or are eligible for) other types of drug coverage, read all the materials you get from your insurer or plan provider. Talk to your benefits administrator, insurer, or plan provider before you make any changes to your current coverage.
