Members of Kentuckians for Single Payer Health Care, Kay Tillow and Dr Melissa Lucas discuss the differences between Traditional Medicare and Medicare Advantage. The primary difference being that under Medicare Advantage your Medicare Parts A, B and D are bundled into one, technically known as Part C. and a for-profit, private insurance company is given by Medicare, a specific amount of money per client to pay the client's medical bills, as well as the authority to determine which payments are made to your providers such as doctors and hospitals and specialists and therapists And which of those payments may be denied. The more claims that are successfully denied, the more profit is made by the insurer.
