We all need to take responsibility for our own healthcare and this law is the start. Having knowledge of Medicare, Med Supp and Part D, I think that we may see some plans such as the following, but again this is my opinion:
Insurers will have a Plan, A, B,C,D etc. Each plan will have the same coverages, however, the insurers "underwriting rules" may vary. Therefore, Plan A under Insurer A may cost $, whereas Plan A under another Insurer costs would be different. Plan B will have difference coverages etc. I can see these plans and coverages being from "bare bones or catastrophic coverages" to very comprehensive and you will get what you pay for. I can also see health insurers vying for the business and thus cost containment, thus the competition will bring prices down.
At present time, having spoken with Blue Rx on Part D, the costs there are determined by contracts between the insurer, Medicare and the Retailer. If I go to CVS for my prescription drugs, I may pay my copay and/or deductible for the drug at say $. If I decided to switch to Walgreens as a retailer, the costs for that same drug will be different because of the contract between the mfr, insurer and retailer.
I can see people comparing costs and this in itself will create competition. These are just my opinions on what I have expereienced with Medicare/Med Supp and Part D.
