Adam, I just got a letter from my company saying that my premium is going up next month. The enrollment period is not until October. Am I stuck with this higher rate until then?
No, you are not stuck with that higher rate until October. Medicare Supplements can be changed whenever you want. They DO NOT have enrollment times outside of the initial enrollment period when you are first eligible for Medicare. Keep in the mind that in order to change Medicare Supplements you will need to answer some health questions.
The Annual Enrollment Period (AEP) that runs every year from October 15th to December 7th is only for Part D Medicine and Medicare Advantage (MA) plans.
