I get this question often. Many of the older persons I speak to have a strong loyalty characteristic which stemmed from they way they were brought up. In many ways this is very commendable but, unfortunately, in some businesses companies take advantage of this situation.
Medicare Advantage and Medicare Supplements happen to fall in this category. This is why it is very important for you to have your plan reviewed on a regular basis. As an example here in New York State some Medicare Supplements are almost twice the cost of others! What makes this more concerning is the fact that these Supplements are standardized, meaning the plans are identical coverage from one company to another.
Part D or Prescription Drug plans can vary from one plan to another. For this reason it is important to make sure all your drugs are covered by your plan. This can change from year to year.
