When Can I Enroll In A Medicare Part D Plan? 
There are a couple of times when you can sign up for a Medicare Part D plan . When you first become eligible for Medicare , you have a seven month window of time starting three months before your 65th birthday month and ending three months after your 65th birthday month . If you are on Medicare for disability and not yet 65 , the window occurs the 22nd through 28th month of disability . You will also qualify during the window around your 65th birthday if this is the case . Every year between October 15 and December 7 you can enroll or change the Part D plan you are on . This change takes affect at the beginning of the next year . If you qualify for certain events , there are additional times that you can change or add Part D coverage . These include moving out of the area of your current plan , living in a nursing home or similar institution , qualifying for state Medicaid or losing other credible insurance coverage . If you think any of these might apply to you , contact your local broker and they will be able to help confirm the qualifying event .
