Your Medicare Part D plan must either provide you with a 60-day advance written notice of any changes to your formulary that might affect you or notify you at the time of a refill and then provide you with a 60-day supply of your medication after you learn of the formulary change.
In practice, most Medicare Part D plans make every effort to ensure that you are aware of any formulary changes that will affect you and will send you a written notice of any drug list changes in your
Explanation of Benefits (or EOB) letter, plan newsletter, or a special mailing.
Your Medicare Part D plan’s website may also have regularly updated information about formulary changes online.
