The main problem is that our government contracts public traded corporations such as the above mentioned to take tax payer government funds and allow these companies to make administrative decisions on what claims get paid or not. The main issue with that is these are profit-based corporations required to put shareholders profits before members. The Medicare & Medicaid Members are secondary to them in regards to being their customer. The shareholders are their priority customer.
It is time for the government to drop these public stock traded health insurance corporations and find a way to contract with not-for-profit, non-public-stock-traded, companies to administer Medicare Advantage and Medicaid.
