TPM was reporting earlier that tougher regulations were part of the deal, but didn't give any detail. The washington post seems to be the first with details saying that a 90% medical loss ratio is one of the new regs. The House bill sets the MLR at 85% and currently most IC's only spend 75 to 80%.
And private insurance companies would face stringent new regulations, including a requirement that they spend at least 90 cents of every dollar they collect in premiums on medical services for their customers
