Whether you choose original Medicare or Medicare Advantage, you can’t set it and forget it.

Doctors leave a Medicare Advantage plan network. Insurers drop your prescription from their list of approved drugs. Sometimes you may be so unhappy that you want to start all over again.

Sometimes you can. Medicare gives you a chance to look at Medicare Advantage or Part D prescription drug plans in your area during its annual open enrollment season. And you may be eligible to change outside of that timeframe.
