Mrs. Schneider has Original Medicare Parts A and B and has just qualified for her state’s Medicaid program, so the state is now paying her Part B premium and she is considered a dual eligible. Will gaining eligibility for this program affect her ability to enroll in a Medicare Advantage or Medicare Prescription Drug plan?

It would have a positive effect.

Explanation:

If Mrs. Schneider has Original Medicare, she can choose to change to the Medicare Advantage Plan. Furthermore, being considered as a dual eligible, she automatically qualifies for Extra Help to pay her Medicare prescription drug coverage.

Extra Help is a Medicare program for those with limited incomes, and the qualifications are to have Medicare and to get help from a state Medicaid program that pays the Part B premiums, such as in Mrs. Schneider´s case

so what is your question?
