Can I join a Medicare plan if I have employer or union coverage?
In some cases, if you join a Medicare Advantage Plan or a Medicare Prescription Drug Plan and also have employer or union coverage, you may still be able to use your employer or union coverage along with the plan you join. In other cases, joining a Medicare plan when you have employer or union coverage might cause you to lose your employer or union coverage. Talk to your employer or union benefits administrator about the rules that apply.
Remember, if you drop your employer or union coverage, you may not be able to rejoin it later.
For more information, see Employer or Union Health Coverage.
