Dr. Mehmet Oz, the administrator for the Centers for Medicare and Medicaid Services (CMS), said Sunday the Trump administration is holding “discussions” on extending subsidies offered under the Affordable Care Act (ACA).

“There are discussions around extending the subsidies, if we deal with the fraud, waste and abuse that, right now, is paralyzing the system,” Oz told host Dana Bash on CNN’s “State of the Union.”

The majority of fraud that Oz is referencing concerns agents, brokers, web brokers and third parties that enroll individuals in the ACA marketplace, according to health policy research group KFF.
