your missing the point Medicare Eligibility. you can be 65 and not be eligible for Medicare. that is why it does not say 65 in the brochure. it says eligible for Medicare. they can keep insurance until they are Eligible. if your client is eligible for Medicare then they will not be eligible for the insurance. you don't have different rates. the rates you are talking about were filled in june of this year. you are over thinking this issue. your original question was about a client. to answer your question on that client. if they become eligible for Medicare then they will lose there plan. If they are not eligible for Medicare then they can keep there plan.
